Scientists overwhelmingly agree that our climate is changing, Earth is getting warmer, sea levels are rising, and it's primarily because of humans putting lots of carbon dioxide in the atmosphere. Whether you already trust in the science, you're undecided, or you disagree with what all this, this video is for you!

"You can always count on Americans to do the right thing - after they've tried everything else."
-Winston Churchill
I think the saddest thing about this quote is it made me feel a little better.
Can always count on Europeans to be arrogantly obnoxious lol. Good thing we helped save you after trying to make Americans British subjectsđ
CaptainHappen you can always count on the british to think they are superior to Americans
@@pcgamerz3081 Hopefully they don't need our help for anything... AGAIN.đđșđžâ
@@mattjohnston5807 lol, everyone can play that: Can always count on Americans to arrogantly bring back WW and diminish the role of the USSR.
Ah, if only facts convinced people of stuff.
It's definitely a problem. I'll get to that in the next video.
It's Okay To Be Smart
looking forward to that Joe! :) EDIT: Damnit, I keep confusing you with Hank Green... You two looks so alike it's uncanny.
Who needs facts when you can just read the Bible and have the answers about EVERYTHING??? And they're all 100% accurate!!
/sarcasm
nmlss dude, I'm an atheist, too, but that was really unnecessary and unrelated. It's not only bible belt nuts who deny climate change, it's more of its own thing that got nothing to do with religion.
haiggoh I'm sure that a vast majority of religious people are climate change deniers. And what's wrong on mocking stupid beliefs?
It's like arguing with flat Earthers. Eventually they start yelling that you work for NASA and throwing things.
Earth is plane at ground level, spherical at satellite level, and circular at moon distance. This is because of general relativity. It all depends on the referential on which you are for observing the Earth.
The Earth can't be flat. If it were, cats would have pushed everything off it by now.
Yea, the alarmist can be insane if you do not agree with their bullshit.
@Seth Adkins IF gravity pulls everything into a sphere, how do you explain the flat head alarmist?:)

Temperature and CO2 have changed from low to high in cycles throughout earth's history. geology.utah.gov/map-pub/survey-notes/glad-you-asked/ice-ages-what-are-they-and-what-causes-them/
"There have been five or six major ice ages in the history of Earth over the past 3 billion years". [Wiki]. "Current CO2 concentrations at 400 ppmv are low when compared with the average atmospheric CO2 concentrations over the past 300 million years or so which ranged between 1000 ppmv and 1200 ppmv." "in past eras [it] reached concentrations that were 20 times higher than the current concentration. . .the Earth is actually cooling, in the context of the total geological timescale. . .It is possible that . . .CO2 will increase normally in the course of the next 50 million years to 1050 ppmV or 2500 ppmV."

I just want to say, I study Earth Sciences and we regularly look at climate change. While Joe Hanson did give it emphasis, probably not enough. The rising CO2 levels are bad, but it is really the dropping pH (the water getting more acidic) what is the true and utter terrifying prospect. I don't like fear mongering, but a more acidic ocean (from CO2 atmosphere to ocean transfer and gas methane hydrates) really will spell the end of life on earth as we know it. Will life end? Probably not. But will human life end? Most likely.
Edit: fixed some grammar errors
iamihop I think you are confusing knowing what technology is needed and actually having the tech. Sure, we know for large parts how to survive on the moon. But even if we fast track it, it could be over a hundred years of R&D before we have a stable colony, anywhere.
And what I am trying to hit home is that ocean life is dieing. The increased acidity is dissolving the shells of animals that need calcium. We know this is a problem, but people dont seem to like it because it wont directly effect them. People* are lazy and only want to do something if it directly benefits them. Sadly, not drowning to death, or starving, are succumbing to tropical diseases in a temperate area of the world dont count as direct benefits.
The main reason why scientist say: "this and that could supposedly happen..." is because we are charting unexplored areas. We dont know what is going to happen, but pretty much 100% of our scientists, the best and brightest of humanity, agree that it isn't going to end well if we do nothing.
No, I dont like fear mongering. But we should be afraid of this very real and very direct threat. I could tell you of all the things that could happen. But from a strictly scientifically point, I would have to claim it as a possibility and not a certainty, even if it is very likely.
But I can tell you, it won't end well if we keep going on.
I myself was very skeptical of the imminence of the danger. It was only until last September when we started investigating the oceans for our Geochemical Cycles course that the facts really started to sink in. Our whole class, usually a very joyful and friendly bunch, couldn't and cant stop talking about it.
Learning of the importance of the oceans was, for me, the turning point. And I am still trying to find words to best emphasize their importance.
PS: sorry it got a little long, really just find it important to explain this.
*: I am describing an average behavior of people, not a specific one for everybody.
iamihop
boy do I feel silly now. I revised my text like three times to make sure it was understandable to someone who isnt in geology xD.
The real concern for me is the stability of gas methane hydrates (GMH) in ocean sediments. It only takes a slight temperature change to make the crystal unstable and dissolve. There are two lighter sides (if you look at it in a very obscure way): the rising temperatures wont affect deep or intermediate ocean right away of course. So that could give us an extra 100 to 500 years. And the increase of sea level increases the pressure too.
That not so fun side is that basically the USGS has done (ballpark estimate) 80% of the research on GMH's. When we made a Stella Model, we didnt have good numbers for anything.
When we tried to calculate the production of GMH there was only 1 article that we could find that gave us something we could use. And even that was with a wide margin.
(for the article, look for: F. S. Colwell, S. Boyd, M. E. Delwiche, D. W. Reed, T. J. Phelps and D. T. Newby, âEstimates of Biogenic Methane Production Rates in Deep Marine Sediments at Hydrate Ridge, Cascadia Marginâ Appl. Environ. Microbiol. 2008, 74(11):3444. DOI: 10.1128/AEM.02114-07.)
But killing of 8 billion people would be hard. But loss of coastal lands, degraded farming (droughts, flooding, soil depletion, saltification), ocean dead zones and acidification increased temps, water scarcity and go on and on. We are seeing deaths from climate stress (climate factors and social unrest due to climate) which could probably kill off 70 to 90% of humanity (again, a ballpark estimate). Wouldnt be everything, but it wouldnt be hard to end human life on earth. We will probably be hit by an asteroid we where no longer looking for. That would be a kind of dark humor.
My real concern is that we just dont know enough, and that when we do, it will be too late. Maybe a bit outdated, but if I where to have kids, I don't want them to live in an Interstelleresque kind of world, where starving to death, or the black lung are legitimate causes of death.
PS: Also maybe important, I am in my second year of Earth Sciences. Not an expert yet, but University does like to grind new information into you.
iamihop Continue, guys! :)
pipu
maybe tomorrow, its 2:30 am for me and have to be at school by 9am
iamihop It sounds like you agree that the human race will at least be seriously diminished if these changes occur. Relying on a few humans surviving the collapse of an ecosystem is risky and a worse case scenario in my opinion.
even if climate change isn't real, does it really hurt to move to renewables? If we protect ourselves now, we don't need to worry all that much about what the future holds, we either know what it is, or are already protected against it.
Right. And the thing is..... IT IS REAL! LETS MOVE TO RENEWABLES!!!
Steve C D I tried to restore you previous comment, but ti didn't work, I;m sorry. But please, do explain, you interest me. How does reducing pollution kill people? Or is it the job loss? Because you can get jobs back with construction and maintenance crews
Steve C D alright, I'll stop speaking to you now. Tinfoil hattists do not speak to me.
A quick search will tell you that wind is already cheaper than fossil fuels in many countries and solar is headed that way _fast_. With those facts down pat, how can ANYTHING be 50% cheaper than fossil fuels and 10 TIMES cheaper than wind, if wind is already cheaper than fossil. That's not how maths works.
Steve C D Umm, my government happens to be anti-renewable... so I don't know what propaganda you're talking about. (Maybe they're extra sneaky :P)
Also, why do you reckon renewables to be inefficient? Solar is almost efficient as coal, and the technology has been in use for MUCH less time and had a lot less money devoted to it.

I live in Sweden and over here almost everybody believes in climate change, I'm a twelve year old girl and at school everybody talks about it. Some are more worried than other but everybody agrees that something must be done. I didn't really know how many people in the U.S.A didn't believe in climate change until now. Truly eye opening to see how other people think about climate change and there's sooooo many who don't believe it! Thank you for this inspiring video!!!
The reason for the contrast in views on climate change between Sweden and the US is primarily down to two things: Education and culture. Swedish education is very progressive whereas in the US it is compromised by pressure groups trying to mould education to their world view.
The Swedes (and Scandinavians in general), by and large, are quite collectivist in their outlook. They generally subscribe to the idea that everyone is better off when we work for collective gains. This is why Scandinavians are far more relaxed about paying high taxes than others: They are confident that well-invested taxes provide exponential results. Americans are far more individualistic. They don't take kindly to being told what to do or how to think, and the White House hates the idea of being subjugated to international bodies such as the UN, the ICC or the IPCC. Since America is so corrupt, they have no faith in their governments disbursing tax receipts constructively. Big industry, in particular big pharma, the fossil fuel industry and the military industrial cartel, are the big winners from US tax spending.
You could also add that the very religious Americans are kinda gullible and prone to latching onto any viewpoints that accord with their own world view, whereas the more pragmatic Swedes place their faith in scientists.
So now you're 14. In school do they talk about the carbon footprint of the military industrial complex?

Thanks for sharing đ
Yeah Sweden are not the main ones to blame....but the US, Russia, China, India, Israel, Iran, Palestine, Qatar, UAE, Saudi Arabia etc...is a totally different matter. Even Japan, Germany, Canada, Brazil and Mexico!
No reason to blame Sweden, the Faeroe Island, Greenland, Tonga, Fiji, Nepal, North Macedonia, Ghana, New Zealand, Norway, Denmark and Switzerland...these are some of the countries doing the best by comparison.
"I don't want to believe, I want to know." Carl Sagan
Then do *MATH*
You don't need to believe, there is nothing to believe in climate science, it's not a religion, it's science and it has facts and proof.
@Charr Aznable Because the earth is round and climate change is caused by humans are clear facts.
@Char Aznable name some that's happened to?
@Andrii Shumskyi huh? I was asking a dude to name some scientists that had their reputations destroyed for 'questioning the narrative'... where'd I say anything about skepticism? Any skeptic can go and perform the same experiments and gather the same 'raw data' then do the math and figure it out.. psychology is the only 'science' with ego bias
I live in Alaska, and when I was a kid, it snowed in September. End of story. But in the past 20 years, I have seen that average climb all the way up until November, with the snow falling less, having far more melting cycles through winter, and having spring start nearly a month earlier than it did when I was a kid. Yet people here, who have lived here and witnessed this, STILL believe it's not happening. People would rather believe a convenient and comforting lie than believe a disturbing and important truth.
The Pacific was in its 30-yr PDO warm cycle from 1980~2008... It's now in its 30-yr PDO COOL Cycle.
Over the past 4 years a rare pool of warm water (called "The Blob") surrounded Alaska, which generated inordinately warm weather around Alaska. There were also 2 El Nino events (2009/10 and 2014/16) which made Alaska's weather mild.
We're just entering a La Nina event, The PDO is in its 30-yr cool cycle and "The Blob" anomaly will soon be gone.
From 2017, Alaska's winters will become brutally cold, especially with the weakest solar cycle in 200 years starting from 2022....
Mellanie Mellbourne u do realize that your brain cant correctly remember somthing from that long ago. So that means its probable the same amount of snow but u just remember it wrong.
Something as simple as remembering what month snow usually fell is not something I'm going to forget in a mere 20 or so years. What I ate for Christmas dinner in 1996? No idea. Whether it snowed in September, October, or November that same year? Easy.
All of that said, scientific proof cannot rely on mere anecdote such as mine. What matters are the data and trends, and sorting through to find if the correlating data are due to causation. I am simply stating that all of the evidence makes sense to me personally, and I don't see how so many people, especially where I live, are adamant that climate change isn't real.
Mellanie Mellbourne If you look at my post of October 27, as predicted, Alaska is now suffering from BRUTAL cold.....
ALL 50 states will experience record breaking cold this week. Frigging Hawaii will get 3 FEET of snow on its tallest mountains, for the first time this early in the season than ever recorded....
Kuwait just got its first show accumulation in November for the first time......evahhhh.
Tokyo just had 2 inches of snow accumulation on November 25th, which is the fist time since 1875.....
Jeez...
The PDO and AMO will BOTH be in their respective 30-yr cool cycles from 2019, so global temps will fall for 30-years thereafter....
We're also experiencing record low solar cycles, which will add to global cooling for the next 100 years....
Can we please stop wasting $trillions on this CAGW hoax????
I can see your mind has been made up, and I certainly wont have mine changed, so I suppose it's best to drop it and agree to disagree.
Comments are painful. Proper science education in schools PLEASE.
They'll never do that. Not with Betsy Devos in charge.
Proper by what standard?
@HUNNID K BEATZ The greenhouse effect and climate change are taught in schools, you know this, right? The education system as it is just allows teachers to remove it from their curriculum if they don't believe it. And isn't it your side that preaches "facts don't care about your feelings?"
Won't help, kids who have republican parents will never believe contradicting science because they idolize their parents and their beliefs.
@@henrikswanstrom9218 you mean the science of prophecies of destruction? Why don't you listen to scientists who claim global temperature data isn't possible to accurately collect? Why dont you care that climate scientists hide their sources so they don't get criticized? Why don't you care that the billions of dollars that has been poured in to one ideological side has also been used to produce hit pieces on Nobel prize winners who dare to criticize the admitted ignorance of the actual scientific method. Criticism is openly not allowed, their science is without fail. You are the kook here, believing in this religion which claims science as its ally yet hides the literal science used to back it up.
who went to the comments 2 find people denying climate change lol

@@killersushi99 what goes up must come down... after we burn out the condensation freezes us over again as the sunlights reflected
Just fighting the good fight
Sat Nov. 8 Northeast Oklahoma 40F. Following week forecast: Low: Monday night freeze of 22F High: Sat Day 53F. Early Oklahoma Winter, 2019. (it will usually warm briefly in January and then another wave of winter worse than the first half commences). This is almost every year I can remember. Some years we have northern style snows, where it will freeze or snow remains for several days, almost a two weeks, or/and then remain cold and dry. Oklahoma is known for "random" weather.. but the pattern is kinda similar each year, it just varies in timing of when it happens. But it's definitely... abruptly winter from mildly warm falls, remains winter with a few struggles for warmth if it's dry, but the systems nail us with the cold.
So, I am not extremely educated on scientific matters. I didn't get a science degree in college. I studied philosophy.
As such, I don't feel qualified to personally understand what the causes of climate change are.
I do however have a decent amount of friends who are engineers, and I have seen the types of alternative energies there are available.
My opinion is; regardless of whether or not the use of fossil fuel and coal are causing the climate problems we see today; we should be using cleaner, safer, cheaper energy, even if our irresponsible use of resources has nothing to do with our environment changing.
Arguing about the cause of climate change makes no difference. Fossil fuels and coal are antiquated sources of fuel. There are FAR better options out there.
+Facey Neck And what are those better sources of energy you speak of?
The fact is you can improve the efficiency of cars, houses and such, but not with the solar panels, windmills and nonsense Al your pal Gore has. Want to get 80-90-% of the CO2 out of your life. Write me, let's have a chat.
I have a plan. Send me $5 million and I will do the R&D to get the first prototype done. That is cheap...Bill Gates is up to $200 million with ecomotors.com and nothing to show for it....
It will lead to 300 mpg cars that can hit a wall at 70 mph. That same car can power your house. That same engine can go into a roadable airplanes (hence seaplaneguy).
So, if you want to do something, then find me the right people to work with. Otherwise keep the clapper shut...
seaplaneguy "So, if you want to do something, then find me the right people to work with. Otherwise keep the clapper shut..."
You seem to be _explicitly_ saying that unless I have the means, time AND education to put into use sources of energy that will improve the globe, I should censor myself from speaking about them?
Why are you so insecure about the spread of information? Could it be because what you propose is preposterous and you fear competition?
Your proposal is extraordinary. Extraordinary claims require greater than or equal to extraordinary evidence for them to have weight.
Your comment was essentially a lot of huffing-and-puffing without substance of any sort. Literally a blow-hard.
The alternatives to fossil fuel are well known and proven. If you really are educated on the matter to a point where your claim could be implemented, you would know this.
Holy fuck. Regardless of what I type on CZcams, there will always be simpletons trying to look like the next Messiah.
Facey Neck
Not scared of spread of true information. Just get the facts right before you open your mouth, that's all. No, just good engineering. I only prove the claim to people who can make me a deal. Why would I want to prove to you anything?
No, just thought I might find some intelligent life out there that wants to solve this oil issue. Since you have nothing to offer, please go away.
Actually, there are no viable "alternative fuels" that works in current systems. Wake up. A fuel is only good with a certain piece of equipment. For example, NG takes too much space to be viable for current cars with the limited stations. If you triple the range you can get to the needed range per volume if there were enough stations. Normally you need more range for alternative fuel, not less. This is why electric cars don't work. The range needs to be 2 x just to compete. Try getting 600-1000 miles on an electric car.. But you knew that, right?
seaplaneguy First you said: "So, if you want to do something, then find me the right people to work with. Otherwise keep the clapper shut..."
...now you're saying: "Not scared of spread of true information. Just get the facts right before you open your mouth, that's all."
Do you see how you're changing your words?
You EXPLICITLY, in NO uncertain terms, told me to stop talking about cleaner sources of energy. Now, you're saying, 'Well uh... I mean, just make sure your facts are in order.'
Shut up dude!
I'm not gonna get into a debate with someone who changes their stance on something as simple as 'shut-the-fuck-up' in one fucking post. If you know how to revolutionize the world with clean energy; great. Go do that.
At the moment you're trying to argue with me about what constitutes viable energy sources, and stroking your own ego. Neither of which is going to do anything good.
The point of my original post should be obvious: whether or not the climate is changing due to human activity, the primitive energy sources we're using are outdated and there are much better options.
I will leave you with this though: No, you cannot currently drive over 600 miles on one single electric charge. So fucking what? EV's were never intended for long-distance travel. Doesn't matter in the slightest though, because electric vehicles could be implemented and altered in most people's cars, as the overwhelming majority of people do not need to drive more than 200 miles in a given day. Leave the fossil fuels to the large transportation vehicles that need to do that.
That's one of a countless other number of safe, easy, JOB-CREATING solutions that you're trying to not look at. And I know you're trying to be a dick about it, because you suggested that I didn't know what I was talking about, and then you suggest that I don't know the limitations of electric transportation, which I am very well aware of. Once again; I have a lot of smart engineer friends.
Move along sir.
Facey Neck
I am an engineer with the solution. I have worked with those "smart" guys from Caltech, Stanford and MIT. None have solutions that work. Sorry....
An electric car is designed with 200 mile range because the stinking battery weights 400-600 lbs per gallon equiv.. Natural Gas weighs 12 lbs/gallon with the tank. Do the math. Electric motors are really only 60% efficient. My new engine will be that with the conversion on board, meaning I get climate control for free via the cycle. Your piece of junk e car needs to run another cycle to cool the car. Try running that Tesla junk in Alaska or anywhere where it is cold or hot. Forget it. My technology will be twice as good in range when it is hot or cold. Fact....
Make work causes CO2. It does not help your religion. Your smart engineer friends have no clue. Find one. Get him on here and I will debate it.
As for CO2, the AGW theory is false, absurd and shows how stupid the smart guys are.
The part where this video fails is that it assumes that CO2 emissions are 100% to blame for out warming planet. No one is going to deny that humans pump out a lot of CO2, but you're assuming that the amount of CO2 we put out has a noticeable effect on the climate. It correlates, but is there causation?
+Jason Bilangino
There is most certainly is a causality happening here.
You can see on many graphs that earths heat follows the CO2 concentration.
Most of the CO2 is emitted naturally, but the hydrosphere absorbs it , we humans have messed with this harmony and now there is a wheel of heating >> consequences >> some consequences help the greenhouse effect >> heating >> and so on...
I think that even if we stop emitting CO2 all at once it wont be enough, to completely solve this problem we'll need to turn the wheel back.
It can only ever be correlation regarding climate change because we cannot conduct a controlled experiment on such a phenomenon. That does not mean that it is 'only' correlation as if it can be dismissed; it is obviously a very very strong correlation, just like the correlation between smoking cigarettes and lung cancer which cannot be experimented on either because of ethical issues.
There's a correlation, and over a hundred years ago chemists showed why there's probably also causation (though that wasn't their aim, and correlation is also not without merit if you can rule out other factors); CO2 absorbs outgoing radiation in a part of the spectrum where water does not, meaning that that radiation "vent" if you like is getting plugged by rising CO2 concentrations. That water vapour traps heat is pretty intuitive to anyone who's been out on a cold winter day with and without clouds, and CO2 works by the same principle.
CO2 isn't the only reason for the temperature increase, but it's the main one. Changes in Earth's orbit, the sun's radiation output (as mentioned in the video) or a lowering albedo can't explain the increase in temperature, so CO2 appears to be the main culprit.
Of course all afaik, but there you go.
Any chance you guys could update the links for the sources? Need to convince a friend. Thanks!
They won't do that climate change biggest hoax in history
Wayne Johnson There is no evidence that proves that climate change doesnât exist. You can search it up, there isnât any scientific data backing up the blogs of random people. If you go onto NASAâs web page, there is a graph on how much co2 is in the air as of this year compared to 1950.
*You're gonna have a bad time*
Megalovania starts playing
*Climatelovania Intensifies*
And now I'd like the two hour version of this!
lol
Tice Roose yus
Tice Roose me too
Ditto.
Check potholer45 for more thorough info. And their video descriptions for the actual studies.
I'll talk off my elbows for a second here, and suggest that what we need to do is to find a way to _shift_ the whole discussion around the main culprit for climate change. I suggest:
*For us to stop trying to yank people off their addiction to fossil fuels and instead, find ways to make them addicted to renewable energies.*
Because I think that we're trying to replace fossil fuels for the _wrong_ kind of reasons...
Right now, any new source of non-fossil energy presents itself as either a solution to climate change, or as a handy replacement for when fossil fuel reserves run out.
_This_ wind turbine can replace _this_ coal plant! With _this_ electric car you replace _that_ gas car! With _this_ solar panel you don't need to worry about the sun _running out_ soon! And so on.
But are these the right arguments one should make to convince people to leave fossil fuels?
Aren't we dreaming a little *too small* with those ideas?
Because by continuously framing things like this, renewable energies keep looking, at best, like a replacement for fossil fuels, and at worst, as an inefficient but _necessary_ replacement for them. Something that we have to use we like it or not.
And so the solar panel/wind turbine/whatevs looks expensive, primitive, and as enjoyable as brushing your teeth or going to the doctor. It looks like "a backup", a desperate solution, a resource you will be _forced_ to use for when everything else fails.
And that's no way to sell the future to people.
So let us imagine, just for a moment, and just for the sake of argument, that renewable energy had been presented to us, not as a "replacement" for fossil fuels, not as a way to "save the planet" or "fight climate change", but rather, as an *improvement* beyond our good' ol gas engines.
Imagine if we thought of it as methods to obtain energy (and therefore, to get shit done) that not only does what fossil fuels do right now, but which can do _even more_ than they could ever dream of.
And before you slam me about how renewable energies are "not there yet", let me tell you the kicker:
We've already done this.
There was a time when a new kind of technology appeared which depended on unreliable sources of energy, which was expensive and technical and which was barely able to do what your old technology did with ease. Yet it became the default source of energy for centuries:
Fossil fuels.
People didn't replaced farm animals for machinery because machinery was "necessary" or good for the environment. People didn't began using cars instead of horses because horses were a "bad habit" or because cars were "saving the world". People switched to fossil fuels in the first place because they were _better_. Because they allowed you to build, move and produce faster, bigger, and on a scale unimaginable at the time.
And I think we're missing the same kind of opportunity here.
So forget about how renewable energy competes with gas or coal, forget about how expensive or technical it is in comparison to what you're used to, forget the initial investments or the mountains of research still to be done. These were all the same kind of problems people had to deal with when selling gas or coal engines in the first place. And they won by framing it like this:
What do the new source of energy does that the old one _cannot_ do? What does it _allows_ you to do as a person, or as a society, that you were _unable_ to do before?
What do renewable energies posses that will make fossil fuels looks not only obsolete, but _barbaric_?
Find THAT pitch, find that *unfair advantage* in renewable energy, and you can finally stop selling it like the backup or compensation prize that it feels like right now.
Find the unique characteristic that differentiates it from the rest. Stop competing with the old one, change the discussion and give people something they didn't know they needed before.
And as a bonus, we get to the save the planet.
Solution is easy. Nuclear :P
Ned Jeffery fission or fusion? ;)
Arturo Gutierrez fusion preferably. But that won't happen any time soon đą

Hello, we are a group of English students from Granollers (Barcelona). We watched your video to learn about climate change and we answered your question in class, as a paper. Here are the students opinions:
Francesc:
Nothing changes suddenly on peopleâs lifes, so if they canât see it they donât believe it.
Marc: They donât believe in climate change, because some politicians, say that itâs fake, or itâs the normal cycle of the Earth.
NoĂ©: Because they suppose that this wonât change their lifes, or it is too difficult to this could happen...
I hope you like their comments!
Have you told your students that there is no known physically possible way that atmospheric CO2 could measurably influence Earth's surface temperatures?

Simple, in their pockets.
The climate agreements will only hurt us in us. Wont solve problemo
I'm 19 and I show my family the evidence for human-accelerated climate change. They know it's a problem but don't seem to understand the severity. I don't know if they don't respect my opinions or if they're not scientifically literate enough to comprehend. Either way, they value the economy and "terrorism" as problems more deserving of resolve. It's really pretty depressing.
wow you are brainwashed. This is a hoax and you have been lied to.
I would try appealing to their worries about the economy and terrorism by explaining how climate change can worsen the economy and increase terrorism.
1. Climate change leads to flooding, natural disasters, a reduction in agricultural productivity (for example the gulf stream could disappear or weaken, cooling Europe and collapsing most of European agriculture). These things would have a significant negative impact on the economy.
2. The negative effects of climate change (natural disasters, flooding, food shortages, economic recessions, ect.) cause social unrest and political instability which increase terrorism
Your family will never do anything to actually affect other people, so it really doesn't matter what they believe. What you have to do is accept that your family doesn't understand climate change and instead focus on changing the minds of people who hold power. Or better yet, become one of the people who hold power in this world and change it for the better.
that's just not true. How likely is it that he will change the mind of a person in power? almost zero.
how likely is it that the people in power do something because more people vote for people who care about issues like this one? close to 100%
get the people around you invested in this stuff and they will vote. voting is the best instrument in a democracy, because everything people in power care about, is to stay in power.
There is no evidence...
I have the utmost respect for science. I have never doubted the scientific consensus concerning the acidification of the oceans, rising temperatures, increasing severity of wild fires and hurricanes. I have never doubted that increasing levels of carbon dioxide is the cause and that human activity is the source of that increase. However, you must also weigh the consequences of reducing carbon emissions. That is what thoughtful people do.
The other day I heard someone claim that we must eliminate carbon emissions now. I thought to myself, "How could anyone be so stupid that they could actually say such a thing?" Think about it. What would I have to do to eliminate my carbon emissions. Well, first I would have to stop breathing. Every time I breathe out I am spewing carbon dioxide into the air. Let's leave this one though. Assume it's ok for me to breathe. Let's concentrate on activities that involve fossil fuels. So, I would not be able to drive my Toyota Prius because it uses gas. Perhaps I could drive an electric car? Well no. I live in an area where my electricity is generated by burning coal. So, while driving electric would be better than driving my Prius, it would not be allowed. Since my electricity come from coal, I would have to unplug my refrigerator and freezer. My potable water is pumped using fossil fuel energy so say goodbye to my water supply. I guess I would have hunt small game and cook it over a wood fire. I would be dead in a few days or few weeks at most. I do not have the skills to live without energy from fossil fuels.
The immediate consequences of not using fossil fuels are far far worse than the consequences of continuing to use them. This is also a fact every bit as much as the fact of global warming. Not recognizing this fact is just plain stupid.
The problem with climate change is that it is a huge problem with no simple solutions. Creating a world that does not depend on fossil fuels will require the energy of a lot of fossil fuel. Global warming is something that has already happened. As I write this California is having the worst wild fire season in history. But life goes on. Rising sea levels will not extinguish human life. People will move long before they are knee deep in water.
What we need is rationality. We need engineering. We need to know costs of doing nothing and the costs doing various somethings and then somehow make collective decisions about what should be done.
No you are wrong on your first point already Breathing is carbon neutral because the co2 was absorbed by plants and is part of the natural carbon cycle. this will not increase carbon in the atmosphere .
But yes we can not stop emiting co2 tomorrow.
@@Dundoril Agreed. I know. That is why I immediately moved onto the real issue of burning fossil fuels.

The real debate is what to do about it.
Why can't everybody just agree that we are damaging the environment?
because some humans think the human race is perfect
You really think experts in climate science are that dumb? A final paper authored by a group of very renowned climate scientist concluded once and for all that:
"1) Depending on exactly how you measure the expert consensus, itâs somewhere between 90% and 100% that agree humans are responsible for climate change, with most of our studies finding 97% consensus among publishing climate scientists.
2) The greater the climate expertise among those surveyed, the higher the consensus on human-caused global warming."
From skepticalscience(dot)com/global-warming-scientific-consensus-intermediate.html, Consensus on Consensus - Cook et al. (2016)
Why not let the experts who studied those issues their entire life talk about it instaed of thinking that us, uneducated brats, can say anything about their conclusions without even having strong evidence?
He was being facetious. Or at least I hope so..
The oceans make climate. You may make it warmer with materials locally. However you could never impact the big picture.

You've convinced me! I've been environmentally minded since before it became fashionable, and before climate change was a topic, but until I saw this, I wasn't convinced that it was humans alone causing the problem. As much as I'm aware of the problems we create for the environment these days, I also wondered if the change in the climate could be part of a weather cycle which began before man walked the earth. Thanks for the clarification.
Me, too. I've been into climate science since the SAME people were panicking about the coming ice age. This was back in the 1970s, after 40-some years of cooling. Of course, they memory-holed the cooling, took its lowest point in '78-'79, and tried to make us panic about the warming since then. Of course, the ice pack didn't block seaways in the '70s and they're not disappearing, now.
We should live cleaner, but the government isn't going to get us there. The government is why we pollute so much, as it is.
the climate alarms should have more to do with the bottom being pulled out of the global food supply.
get up to date here, and carefully forward to academia.....climate change is more due to loss of carbon sink, ( loss of topsoil and deforestation )
it's just that most climate scientists never even saw it, ( well we all have to eat, right? ...so it subconsciously gets discarded )
Meanwhile, in paleo-anthropology, linear human evolution has become Shattered theory....and it turns out that past interns in the field, ( who got hooked on the african heroin ), latter in their carriers took positions interpreting the data, and through the Shear Terror of the Withdraws, put the source of their junk at the center of the universe....well the reality is that approximately 1 /5th of sub-saharan DNA came from something that was not even bi-pedal at the time, and that whatever it was had skipped over the first 2 to 3 million years of homin evolution....so while sub-saharans are technically the same species by 4/5ths of their DNA, they also Technically carry Species Invasive DNA, and are NON-FEASABLE to the human species......they breed faster than the food grows, into a murderous reproductive swill, if they have food, or into withholding nutrients from their own starving children that they have the energy to make more....they are litterally a caloric sink hole from hell, and do not report their numbers, or income, to facilitate endless growth, ( i have seen the loss of Two Feet of american topsoil in my 57 year old lifetime, we are down to inches, and i traced the abnormal losses back to africa's "humanitarian aid", which turns out to be heroin money laundering.... humans can't be like that, we live on a finite planet, and have the ability to get what we need......so back to my original statements now, it turns out that people of sub-saharan decent have been causing climate change For Thousands Of Years, and we are just further into a tipping point than most would be comfortable admitting .... we just need to get sub-saharans re-classified as a planetary invasive slated for extermination, and the planet will begin recovering.....we have CRISPR now, and can bring their Species Applicable DNA back in Latter..but their Invasive Sequences have to go.....but don't talk to them about it because they get information about the rest of us faster that we do about them as it is, and they kill people who find out.....they are not like they are on TV when you live somewhere near where they are pulling out shiploads of food, and they have been doing this as far back as i have well studied in the united states, but much further back in the paleo-anthropological record....history shows, whenever they meet a supply and demand food system, Total Disaster soon follows....and trying to keep "everyone" feed ends up an exercise in fueling their methane factory and near term future starvation.
You haven't changed my mind at all! (Okay - because I already accept the facts of science anyway.)
But any time I've tried talking to a science denier, they immediately burst into a tirade of conspiracy theories. It's like trying to educate a brick.
You would have thought, with global temperatures going up and up and up, they would show a bit of humility and perhaps accept that the people who study the climate for a living know what they are talking about.

I think a good way of convincing people to act would be to go into greater detail and depth about the consequences of our activities. People hear "rising temperatures" and "rising sea levels." But what they need to know is that such things can cause mass extinctions, the displacement of millions of people on coastal cities, etc.
The sweeping our economies causes past extinctions also.

One of my friends asked this question ... If Cities are emitting CO2 more that Oceans while would Artic or Antartic ice melt ? How do I address that. Does the C02 equally across the globe ?
explain how diffusion works. if you release laughing gas into a room, it spreads around the room. it doesn't just stay in one place. any other gases spreading through the air also works.
by global warming theory, water vapor is a green house gas.. and water vapor (or steam) dwarfs by far the amount of CO2 in the world's atmosphere which makes any fraction increment of CO2 insignificant .. funny how you forget to mention that.. so when I heat water to make my coffee I'm destroying environment.. man, I'm feeling bad now..
+Pascoal Freitas You should probably learn about "positive feedback loops" before trying this one again
+It's Okay To Be Smart CO2 concentration in Mars's atmosphere is 16 times higher than Earth's.. and it is hotter than Earth.. ops.. wait.. no, it is not.. is this one good enough for you?
+Pascoal Freitas The atmosphere of Mars is 1/100th the density of Earth's and even if it were 100% CO2 it couldn't effectively trap solar radiation. Next!
It's Okay To Be Smart exactly.. but does it not contradict greenhouse gases theory?? hahaha.. thanks for confirming it: what matters is the amount of all gases in the atmosphere not only a few ones
+It's Okay To Be Smart You should probably reference how your argument rests on amplification effect of CO2 for your positive feedback loops to work, and the data collected does not match climate change prediction models......at all.

I wish that people over all the world can hopefully open their eyes from the darkness and see that this problem can be resolved. Climate change cant be stopped, it's got to a point where it will cause the wildlife and our population extinction just because we didn't understand the effects of our mess with COÂČ. just because we "can't stop climate change "it doesn't mean that we should keep going with our ways. We all should take on the main problem and change it to make the whole planet a better place for both humans and the wildlife.

I'm from germany, and the problem is huge here. Naturally, our state/ government takes for ever to change things. Its just how we are as people here. The same goes for everyday life. I have countless friends who could EASILY ride the bike to work, or for gods sake, take the bus, but they just don't care. "It's more convenient" and "I don't want to be sweaty when I arrive" are just 2 out of many excuses I hear. Having a car is no problem. Use it for heavy groceries and visiting people you can't reach that easily otherwise. Speeding across the motorway with 220 km/h and driving 4km to work everyday is.
And that is just one example. I don't even want to start about the amount of energy we consumpt and how easily we could turn it down (just don't leave your charger plugged in, use reusable packagings, don't order too frequently on amazon etc.), but in my experience, people here are just too "unaffected" to change things. By that, I mean most of the people, not all. There are exceptions, but few.

Most of my closest friends do not think that climate change is real, and this seems to be because their parents do not believe that it is real.

For every major discussion topic in history, there have been people on both sides of a debate who base their ideas on a vague faith in something they've been told. So the discussion about climate change needs to be from a scientific perspective. I'm by no means saying I understand even a fraction of the depth of climate science needed to evaluate it properly. I'm saying the discussion should be without prejudice, and with as little emotion as humanly possible. The most important value in science is to question everything, they tell you that in grade school but not many take it to heart. Everyone knows the most legendary scientists have taken down paradigms, but not many are open to questioning mainstream theories themselves. No theory is ever proven and there are always alternative theories. A scientist has weakly supported opinions and strongly supported theories but they are NEVER certain. This is what i mean when i say scientific perspective. Not more or less knowledge, not on a particular side of any particular debate.
We have to try to understand the more complicated aspects of the subject , not simply quote the media.
This topic, climate, is a very, VERY complicated one. We all know that weather is not climate. You cannot simply look out the window, see that it's snowing and say there's no global warming. You also cannot point to any forest fire or hurricane and say its caused by "climate change". It is not simple. It is a matter of probabilities and statistical analysis beyond my comprehension.
It is widely established that the Earth is on a natural warming trend. Climate always changes in a local area, on different scales, but over many years the NET trend is toward a warmer Earth.
đ§most scientists agree on:
- glaciers are on a melting trend, most glaciers globally are receding
- the Earth was probably due for a warming trend (although trends in climate are not a predictable pattern whatsoever), it would be regardless of humans , we recently (in geological time) came out of a glacial period. This is due in part to the Milankovitch Cycle, a well established and academically accepted understanding of the cycles of Earth's climate dependent on the tilt and relationship to the sun etc
- a change in global climate trends can have extreme effects as equilibriums are disturbed , (like the wind in the spring)
- the greenhouse effect is a natural, very IMPORTANT part of our planets ability to sustain life
- levels of C02 are measured in certain locations, some in Tanzania and Hawaii because secluded and away from urban heat Islands, (keep in mind the local conditions including volcanoes that can increase C02 readings).... it gets complicated when you start thinking about atmospheric chemistry - I cant wait to learn more!
- C02 levels are rising (if you are to believe the data and trust the individuals who put out the statistics, which personally i don't)
- the changing climate will effect all life on Earth, some organisms will benefit, others will struggle, evolve, ecosysytems will have to rearrange, people will have to move houses away from rising sea levels etc Coral reefs have already shown adapting behaviour, when the seas warm they are bleeched and their mutualistic bacteria that photosynthesize for them are killed off but they are OBSERVED COMING BACK because they adapt and change their skeleton
- contrails add cloud and change local weather patterns, condensing more water and making it fall more often? I am unsure the effects of this system
there's more but.......
- the Carbon cycle is necessary for all life on earth. fossil fuels are a reservoir for plants. increased CO2 increases vegetation.
đ§Opinions based on faith/belief:
Whether or not humans and fossil fuels are putting enough C02 into the atmosphere to accelerate the greenhouse effect in a SIGNIFICANT manner AND whether or not this is detrimental to the planet or simply another change in the environment that humans and all other organisms must adapt to because that's the nature of life on Earth
Even IF there is any kind of substantial effect from humans, lets be clear and not narcissistic, the Earth and life in general will be fine. The biosphere has survived drastic changed in climate time and again over the millions of years of evolution. The nature of life is to adapt. The adapting coral reefs as mentioned, who is to say this isn't what they always do in fluctuating temperatures and scientists are simply just observing it now and believing the bleeching to be "our fault"
Do I hate polar bears and revel in the idea of their demise? No, on the contrary, the thought of any living thing being harmed in any way saddens me. But emotion has no place in science. I am very wary of those who try to sway me with emotion.
Respect others beliefs without judging or thinking you're better than them or assuming they are horrible people who don't care. I care, probably more than most. I always bring my own water bottle, a coffee bottle to the coffee shop, love the reusable bags, use all my things until they are functionally unusable even if they don't look great anymore, I have a biodiverse lawn etc etc I do everything I can that I feel is right in my local community and ecosystem not because I want to impress anyone but because it is better. Pollution and mass production suck, I don't like a lot about it and there are better ways of doing things. I also don't hate humanity and think our species is a "plague" to the planet. We are beautiful and deserve to survive like every other animal. Every bad thing that happens to every other animal is not OUR FAULT. NATURE IS NOT A FAIRY-TALE. ANY EDGE ANY OTHER ANIMAL CAN GET TO SURVIVE THEY DO without remorse. WE CARE, we try to do right and have morality, that's good, but we should not be degrading our own worth and existence, that is a ploy by those in power. I don't feel bad about driving a car, I do wish it was electric but I cannot afford it and if the powers at be really cared about the pollution they would make electric cars better and cheaper. YES they could in the snap of a finger but they don't give a rats ass, and carbon taxes do NOTHING but put money in their pockets.
If I'm presented with evidence that strongly points to humans ARE accelerating the trend and this is horrible for the Earth, will I admit I was wrong ? Yes, wholeheartedly and without shame.
The point is to follow the evidence to the most likely truth regardless of belief.
You forgot Carbon-14 in your explanation. Because it's radioactive there is 0% Carbon-14 in fossil fuels and the percentage of Carbon-14 in the atmosphere is falling at a faster rate than Carbon-13 exactly as expected of burning fossil fuels. It's a minor issue though because either way the proof is undeniable. Thank you for the video sir.
I didn't know that!
Why is there so much conflicting data on this issue?
Because big companies make a lot of money with fossile energy. It is the easier way to go.
It is the same as it was with the smoking companies when the health risks of smoking became popular. They made their own laboratories and payed their own "scientists" to publish data in their favor.
ĐĐŸŃĐŸ ĐĐ°ŃĐșĐŸĐČ because there isn't. it's real. all intelligent people know this
Same reason there used to be conflicting data on whether tobacco products were bad for you or whether sugar was bad for you. If people can make money by lying to the world, a lot of them will do it no matter how many people die as a result.
There's no conflicting data on how far the Moon is from Earth, for example. That's why we have science. Then you have misinformation because of special interest, mainly through the mass media. So it is important for people to make the distinction between information and science. I just want the science, not people's opinion. the problem is: who do you trust, and how do you judge that?
ĐĐŸŃĐŸ ĐĐ°ŃĐșĐŸĐČ The ones with evidence
Duh..?
If you like the background music. Check out "massive attack tear drops"
Excellent video. Thank you.
Anyone else here because your teacher sent you the link?
I believe the reason a lot of people don't believe in climate change has to do with Petroleum companies. They're rich, and have the power to spread rumors that completely go against reality
You can't be more right but not all fossil fuel companies do not want to change.
And also because of the boss of indoctrination : the military industrial complex

No we simply dont believe it because science dont support it. There are enough measurements that show different data that IPCC chose to not use. If that is not good enough reason I dont know what is. Its like reading assement on junkfood being healthy by McDonalds company.

Thank you
Part of the issue isnât just that people donât believe in the science. A major divide right now is based on politics and political activism. Many skeptics are simply not convinced that government is the solution to tackling issues, and as such, shouldnât be the solution.
Itâs not just that people deny the Earth is warming. A great chunk see human innovation as the solution. And as a result, those of us who do get labeled as science deniers by political activists because they simply cannot see how individuals in a free market can solve the issues we face.
Great presentation by the way. I think sticking with the facts like this in a calm and rational manner is the way to bring those that are skeptical to consider the data.

Thanks for this video it's great for school
+Okay "Have an idea for an episode or an amazing science question you want answered? Leave a comment below!"
Sure. Explain, using physics, how 400 ppm CO2 can warm the atmosphere. No magic involved. Use Fourier, but all of his thinking, not just the part he rejected "greenhouse effect", and explain how a glass covered building that does not allow wet air expansion to rise (doing work) can be considered a model for anything but another greenhouse.
The so called greenhouse gases do not trap heat as shown in the video and which is generally taught in schools. The actual physics is that these gases like carbon dioxide, methane absorb the infrared radiations from the sun and convert them into their vibrational energy. Later on as they absorb more infrared radiation i.e. Heat.. they start losing this vibrational energy again in the form of heat because it is the easiest and simplest mode of loss of energy. That's why we see that most losses of energy in our nature and even in the industrial sector are into heat like friction and air resistance
The temperature data that shows that the globe is warming on average are found within cities often in airports. In other words, this data does not account for the urban heat island effect.
+Ibliss Even if that would be the case (which it is not), it would not have an effect. See my comment on +swingdocta
+Reiner Jung It does have an effect but it's minor and negligible

If I had a dollar for every time someone says âthe evidence is overwhelmingâ I would be able to hire a hitman to make sure nobody utters the phrase again.
Thats a good one
Well itâs cause it is indeed overwhelming, itâs just when itâs presented to people who donât believe in climate change, they either deny the evidence or make something up.

What you need to know is politicians cannot control the climate
gpettipas they choose whether or not to fund oil companies or tree planting companies. So, yea they kinda do
@Seth Adkins CO2 is not a significant driver of the greehouse effect.
Neither can anyone else control or change the climate, Skippy.
What do you mean by 'it's okay to be smart'? Like it's not cool to be smart.
its not. da soshal meedeea is fool of mizpellings and gramatical airors. #TooStupidForSchool
I'm joking though. I'm not so sure as to how old you are but, the smarter peple of the world used to be bullied more. They still are but they're older and the nerds are scientist, engineers, and programmers while their bullies are politicians. This video talks about their fight.
Thatch Lobos Yeah my Gen is more tolerant to intelligent people, when I was growing up, I was praised for my intelligence and was never really picked on for it. I'm glad today science is cool ^^
Dr Alec Reaper I was somewhere in between. somewhat bullied but in most cases i was too big to bully. It's good to be big and smart. you can talk shit and then intimidate anyone who tries to pick on you.
We'd rather be smart than stupid, but you know, you go do your thing and be stupid.
I watched this video for geography. This is a really important issue and this was so well explained, thank you! This is really interesting as well.

Average temperature rise is about .35 degrees over the last 50 years according to a group of about 30,000 scientists( some from NASA. UC Davis did a study on methane gas and the result was very little impact on the environment. The climate is always changing, sometimes it is warmer and sometimes it gets colder. Global warming group switched to climate change to be PC.
This video came out nearly 5 years ago. Look how far we've come....
Yeah, look at how wrong they were!
@@VariantAEC and how wrong where they exactly we have lost thousands of species in this time frame so do entertain me with your hardcore proof backed by real science you all so belive and hold so dearly
@@Sora_Nai
Which ones went extinct?
Why is 2019 cooler than 2018 which was cooler than 2017 which was cooler than the eecord breaking year 2016 (which in and of itself was still much cooler than 1934) when atmospheric CO2 concentrations continued to increase uniformly?
Additionally since Scripps started recording CO2 concentrations anthropogenic emissions rose 720% while atmospheric CO2 only rose 299%. Where is the linearity?
@@VariantAEC cooler? wtf numbers are you looking at? your local ecologies averages? because the world average has been steadily going up.. and do you even know why co2 is the main one that talk about? because it's a photon sink... Do you understand what a photon sink is? also co2 levels are easily documented year to year in areas where trees are allowed to grow for many decades... so in cases of several 100 year old trees they are given access to several 100 years in collected co2 samples from year to year (each ring being roughly a year in cyclic climates)
@@kingscroach
The world averages can be found here and the "unadjusted" (meaning less adjusted) data can also be found here:
data.giss.nasa.gov/cgi-bin/gistemp/stdata_show_v4.cgi?id=JQW00021603&ds=15&dt=1
Yeah the world isn't getting hotter. It's only after these scientists screw with all the data that it gets twisted up and is magically made to show heating.
You may also have as much difficulty as I did trying to figure out exactly why and how some of the adjusted and unadjusted data are so distant from each other.
Anyway this is one of those things you can prove by being alive for a while and tracking temperature, precipitation and other meteorological factors. Some regions are seeing warming not all most actually aren't and the only nations with any good weather records show the climate is more of the same with extra boring sameness to come for the next century at least.

IPCC 2014 report
â there remains significant errors on the model simulations of clouds. It is very likely that these errors contributed significantly to the uncertainties in estimates in cloud feedback, and consequently in the climate change projections.â
âThese projections were not intended to be predictions over the short time scales for which observations are available to date.â
Yet the conclusion of the IPCC are clear: "We're at a crossroads. What happens between now and 2030 is critical."

Kuldip Tangri what's your current level of understanding of physics and chemistry? Knowing this will assist in answering your question in a way that you will be able to understand.
@@boilerhousegarage It does, and we can. It creates an insulating blanket, just like the glass on a greenhouse. are you also refuting well established physics to prove yourself right? get out of your bubble!
Not a bad video, and very concise for the topic.
I love Potholer54 and his climate change saga more though.
He delivers information and humor.
He is awesome
As far as I remember, water very very minimally expands depending on temperature. Especially from a few degrees. Or does it? (Ice's melting effect is obvious though.)
Yes, it "very minimally" expands with temperature, and the temperature rise is small. However, the average depth of the ocean is around 3700m (12,100'), so that "very minimally" and "small" has a lot to work with.
You are not telling the whole story here. Do we make more or less CO2 now than in the 1970s when we saw the fastest change in temperature? Also, you failed to mention that the big scary 2,000 GT of human based carbon emissions you mention is a drop in the bucket compared to what our oceans and land biomass contribute. The point I'm trying to make is that the global climate is very complex and to say that consensus 'proves' that we are to blame for these varying factors and models is not what many bonafide climate scientists believe.
3:04-3:13 So.. Easiest course of action is to plant a lot of trees? Sounds easy enough.
But we would need to plant more trees than we cut down. That's almost impossible at the current rate of deforestation.
+Reptile \o/ DANG IT, HUMANS!!
Trees are great but are part of the short carbon cycle. So in 100 years all the CO2 they absorbed will get released when they decay and rot. CCS technology is really our best hope at making a meaningful difference. Funny enough, CCS tech is becoming more commonplace since it's used for advanced oil recovery.
fact 11 - again you need to do a first order analysis of the instrumental data before concluding net sink/source statements. Natural emissions have increased - hence a net source.
I hope this is not too late for asking, but.. shouldn't the shift in the magnetic field also be kept in consideration, when talking about climate change?
people react only on there feelings and not on facts.
The best thing is to scare people of what will happen.
+Lars Andresin What they are doing is planting a seed of doubt in their mind. You can never really prove anything like climate change without there being some doubt. Just like with cigarettes, they said "But...But..Are cigarettes really bad for you? Can we be sure?" Doing that alone prolonged the whole cigarette debate by a few DECADES! History is repeating itself.
alot of people just say: "Yes lets save the clima" but they never do
And sorry but I'm not any better like alot of us.
@5dope you're so damn right. I'm not any better than almost everyone. We are all just people that wants to save the clima but we are not willing to sacrifice any of our stuff or opportunities in this life for the clima.
Because if one of us changes his life the impact will be resulted in nearly nothing.

Temperature is complicated as are greenhouse gases and other atmospheric gases. We may never know all long-term general atmospheric temperature trends and atmospheric gas trends. A LOT of it goes beyond our technology's capabilities. Facts may not decide our future. Unfortunately, that usually makes things political. That's why I put so many climate change videos in a playlist called "Science and Politics" and not the one I have called "Science". On a side note, I loved the rendition of the climate skeptic you showed, especially what he said about Al Gore as supreme polar bear emperor.
