Today is Feb 12, 2024. I watched the video talking about the climate change. During this time, I just passed three questions mentioned in the video.
First question: What is the climate change?
Climate change is about the heat being added to the Earth system. Human activities like burning fossil fuels, cutting down forests that have been standing for hundreds of thousands of years create carbon dioxide in the atmosphere. Carbon dioxide is a greenhouse gas. The more greenhouse gas you have in the atmosphere, the more of the sun's heat get trapped in the atmosphere and the warmer the surface gets and that's why it's called greenhouse effect.
2. What are greenhouse gases?
Greenhouse gases exist naturally in the atmosphere. If there's no greenhouse gases in the atmosphere, the world would be too cold for comfort. Greenhouse gases on their own are actually great. It helps to insulate the Earth. The problems we are facing now is the numerous of greenhouse gases being added to the Earth.
3. What are fossil fuels?
All of the systems that underpin our lives. So how we produce food to eat, how we create energy to heat our homes, how we create electricity to power our devices, how we fuel our cars. For the most part, historically, we burn fossil fuels to produce energy. Fossil fuels are essentially from plants and animals from millions of years ago. We burn fossil fuels to create heat and electricity and everything. But then we also produce carbon dioxide as a side effect.
is this for geography homework or something lol
@@The_Cat_God at least hes educating people
@@allayna1688 ok
User, that is simplistic.
Co2 which most consider the most powerful actually decreases in potency as it's concentration increase on a logarithmic scale. H2O is actually far more potent and has very much more influence.
That said every action has a reaction and increasing temperature increases water evaporation which is cooling. There are many other reactions which doesn't follow the more CO2 equals more heating, it's much more complex.
The sun is not considered by the IPCC but it too is variable.
i only got the first question but thanks
I am an electric engineering statement and I do believe that there is a permanent source for producing electricity❤
I just love this episode and topic on which the whole vidoes are talked.. There is a still hope to control the adverse effects of climate changes.

I will tell you what climate change is It is something to say when politicians want to change the subject they do it all time
Climate change is not "turbocharging weather events".
The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that severe weather events cannot be detected as increasing, nor attributed to human caused climate change:
Increased Flooding: not detected, no attribution.
Increased Meteorological Drought: not detected, no attribution.
Increased Hydrological Drought: not detected, no attribution.
Increased Tropical Cyclones: not detected, no attribution.
Increased Winter Storms: not detected, no attribution.
Increased Thunderstorms: not detected, no attribution.
Increased Hail: not detected, no attribution.
increased lightning: not detected, no attribution.
Increased Extreme Winds: not detected, no attribution.
There is no climate crisis.
The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that certain severe weather events cannot be detected as increasing, nor attributed to human caused climate change:
Pages 1761 - 1765, Table 11.A.2 Synthesis table summarising assessments
Heavy Precipitation: 24 out of 45 global regions low confidence in observed trend (12 medium confidence), 43 out 45 low confidence in human attribution.
Agricultural Drought: 31 out of 45 global regions low confidence in observed trend
(14 medium confidence. No high confidence assessment). 42 out 45 low confidence in human attribution (3 medium, no high confidence).
Ecological Drought as above.
Hydrological Drought: 38 out of 45 global regions low confidence in observed trend.
43 out 45 low confidence in human attribution (2 medium confidence, no high confidence).
So the IPCC are saying we didn't cause droughts and we didn't make it rain. How surprising!
There is no objective observational evidence that we are living in a global climate crisis.
The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed:
Air Pollution Weather (temperature inversions),
Aridity,
Avalanche (snow),
Average precipitation,
Average Wind Speed,
Coastal Flood,
Agricultural drought,
Hydrological drought,
Erosion of Coastlines,
Fire Weather (hot and windy),
Flooding From Heavy Rain (pluvial floods),
Frost,
Hail,
Heavy Rain,
Heavy Snowfall and Ice Storms,
Landslides,
Marine Heatwaves,
Ocean Acidity,
Radiation at the Earth’s Surface,
River/Lake Floods,
Sand and Dust Storms,
Sea Level,
Severe Wind Storms,
Snow, Glacier, and Ice Sheets,
Tropical Cyclones.
How about some quotes from the UN's IPCC AR6?
"There is low confidence in the emergence of heavy precipitation and pluvial and river flood frequency in observations, despite trends that have been found in a few regions."
"There is low confidence in the emergence of drought frequency in observations, for any type of drought, in all regions."
"Observed mean surface wind speed trends are present in many areas, but the emergence of these trends from the interannual natural variability and their attribution to human-induced climate change remains of low confidence due to various factors such as changes in the type and exposure of recording instruments, and their relation to climate change is not established. . . The same limitation also holds for wind extremes (severe storms, tropical cyclones, sand and dust storms)."
There is no objective observational evidence that we are living through a global climate crisis. None.
Are you trying to prove climate change is natural?
Heres three reasons why climate change is mostly caused by human works :
My first point :
Yes ,climate change can happen naturally, like in the sun , but temperature on Earth is increasing more rapidly , maybe even faster than the Sun. Human works , like different diamond or gold mines produce methane when the soil is dug up and that methane gas rises to the air , reflecting sunlight from the sun more , creating what is called a greenhouse effect , heating up the planet faster , increasing the temperature at least by 1 degrees Celsius by 2025 .
My second point :
Factories produce different chemicals like mercury , plastics , petrochemicals, pharmaceuticals and even excess gunpowder, and a wide variety of different chemicals, killing off the plants in the water and other marine animals , making the levels of photosynthesis decrease rapidly and causing carbon dioxide emissions to drastically increase while oxygen levels would plummet, warming up the surroundings as a result , along with other greenhouse gases that are also produced.
My third point :
Electrical appliances, such as fridges , produce excessive chemicals such as chlorofluorocarbons (CFCs) or hydrochlorofluorocarbons , which deplete the ozone layer , heating up the climate .
My fourth point :
Trees in the Amazon forest the size of two football fields are being cut down every hour , and since trees help absorb carbon dioxide and other harmful chemicals, when they are cut down , they release a huge amount of carbon dioxide into the atmosphere, causing the temperatures to warm up .
My fifth reason:
Nuclear power plants which generate electricity through nuclear fission also produce greenhouse gas emissions, and creates nuclear waste , which , in turn to store them , we need to cut down an estimated 2120 trees by 2026 to supply enough space for the nuclear waste , which in turn create more carbon dioxide, warming up the climate.
My sixth point :
The domestication of livestock are rapidly increasing, and farmers , in turn burn down more trees to supply more space , creating the haze epidemics ( 2018 -2019) in Indonesia, India and even China. On top of that , farmers try to feed their livestock as much as possible, creating more emitting of greenhouse gases (farts and burps ) which in turn warm up the surroundings even more !
My seventh point :
Cars that run on gasoline create even more greenhouse emissions by chemical reactions in their engines , releasing carbon monoxide, methane , and most importantly, carbon dioxide.
My eighth point :
As more gasoline is used up , more fossil fuels are dip up and burnt , creating carbon dioxide, hydroxide , and much more chemicals, creating more greenhouse emissions by everything put together .
My addition to my fifth point : nuclear power plants can also produce greenhouse gases like carbon dioxide, sulfur dioxide ( poisonous chemical, created by burning sulfur )and other stuff that also warm up the surroundings
Plus , how about the super cyclone that hit the eastern coast of New York City ? Your “evidence” of the matter seems outdated from 2019 . The cyclone was caused by - you guessed it- climate change , which is why the 1 billion oyster program was created to restore the city’s carbon footprint.
How about the melting of global ice caps ? The world loses about ten metric tons of ice per year! That is about the weight of 400 elephants of ice ! How is that not caused by human activity?
How about the Australian wildfires in 2019 ? This disaster was one of the largest wildfires in the world since the 2000s !
How about increasing change in rainfall patterns? Ever since humans first began to increase the greenhouse gas emissions, different floods are happening around the globe, and have you heard that Ireland is about to sink by 2190 ?
Its me, darlu g.
We need energy to heat and cool and run our machines etc.
Renewable energy sources can’t supply enough of our energy needs.
Maybe reducing the world’s population would mean we’d need to produce less energy and our reliance on fossil fuel sources would be reduced.
ITS MORE HARD TO LIVE WITHOUT IMPATHY BY OTHERS...CRUEL WORLD TO CRUEL WEATHER ISNT IT! "
Now we know that oil and gas can be formed abiotically through subterranean heat and pressure, and that the Earth contains a virtually endless supply - oil is the new ‘renewable’ energy.
Love this podcast! :) I like everything, the topic, how the interview goes, and the subtitles. I wish I had known it before, although I've been watching BBC but didn't explore this in the past. I have been listening to different podcasts, this one is the best! Wish we could have more of this informative topics! :) I'll keep this on my regular routine! 🙂🙂

Ur politicians are all corrupted so.
So why if OAP's are told to turn down the heating, to walk intead taking the car, Yet they send people they employ for a 5 min clip 1st class, with film crew, go to every sporting stage, and take all thier staff, Balding Linekar, Myrie, Rita, Chakroborty, Anita Rani,Hariry bikers, Rick Stien, Vicky Young, Sarah Smith, Nadia Huessian, Anju Adnam.

Rome's Portus grain port 200 AD at sea level, now up to 40 metres above sea level, is obviously not silted over, as NASA proclaims, attached, because it's visible on Google maps and satellite. Google maps indicate a current elevation about 40 metres above current sea levels.
CZcams Drain the Oceans Rome pictures the evidence. It's the tip of the iceberg. There's a huge community of marine archeology studying sea levels fluctuations. Mostly below sea levels but some above. Apparently one researcher sought permission to scan the flood plains below Troy.
Apparently there are hundreds of ports from the Roman era which are now above sea levels. Isle of Thanet, Shore Forts, Port of Rye UK. It appears the conventional explanation is "SILTED OVER" but new evidence, beyond a reasonable doubt, is sea levels were higher in Roman times. Rebuilding global ports needs 100 years lead time ( check with Arcadis, Netherlands) and because we're talking about the End of Civilization, this issue is STAT.
Scientists who debated a physical environment without inspecting it are like Ancient Greek scientists who debated how many teeth a horse has without inspecting horses.
It's urgent that marine archeology, inSAR, NISAR, Adrok Scotland ( AI and big data radar points) and ground penetrating radar ( a new technology), geomatics ( a new science of ground instability or movement), mining tech, volcanology, ash layers, and so on re-examine the physical evidence because civilizations built on ports end when their ports are high and dry or submerged. Don't know whether sea levels will return to their (recent) peak in 10, 100 or 1,000 years, nor what the cyclical processes are.

Of course back in the 19th century rivers & lakes use to freeze over in the winter & there were even makets held on the Thames & Matt Taylor of the BBC said it was caused by low sun activity for years but in the last 20 years there has been high activity by the sun, does any body not think that may have something to do with climate change? Of course there have also been over 2000 nuclear bomb test since the WW2 with over 500 emitted into the atmosphere. All of these things have made differences to the worlds climate & I sincerely believe that all that radiation has caused one in two people now getting cancer.

One thing I notice about climate videos is they're too wonky and academic for regular people to take this issue seriously. It's always framed as either gloom and doom or a fun educational adventure. Nothing showing how an earth on fire will affect people's practical lives.
Because it is quite gloom and doom if you want to be honest. Scienctific facts don’t give a shit about your feelings to be true. We’d accept it and act quickly or suffer the consequences
@@thanhnguyensolo and this approach has gotten you how far with the general public? Who you very much need?
Yes l think we should be more serious cause fossel fuel is the big joke
So why do the BBC keep sending thier presenters 1st class for a 4 min clip on some stupid, "and finally" news article and then tell OAPs, to turn down the heating an switch off the plug when they are cauing so many emissions and the poor OAP ends up in hospital with pneumonia?
@@thanhnguyensolo😂😂😂
Keep going, I love to watch stupidity at work in climate change people lol. You people make me laugh so hard hearing how you actually believe the crap your spewing even though it a load of 💩 and not true. Some on my side want you to shut up but not me, I love comic relief. To see just how dumb and gullible you are!!!!

geo homework
After the energy crises of the 1970s we statarted the intensive use of energy and in global characterised the era of industrialisation. Future moves in direction we reguire! For instance many European countries during the last few decades uses the hot water traditionally to supply energy. Low enthalpy sources for heating offer various spectrum of applications. It is time for all of us to prevent it with renewable energy sources!

Now halp my sorry good bay
Today is Feb 17, 2024.
1. Why is the Earth getting warmer considered as a global issue?
Some people will be thinking I like hot weather. What's wrong with it?
Some parts of the word are already pretty hot. If you are in a particularly hot city and that suddenly gets a chunk hotter, that's going to make it a lot harder to live in that city. Beyond that, around the world, we have seen first-hand the effects of the world getting warmer. Climate change is turbocharging all sorts of extreme weather events like heatwaves, floods, droughts, wildfires.
2. How do the climate change cause floods and?
That seems to be the opposite of what some people have thought would happen. Warm water takes up more spaces than cold water. And so, you get this thing called thermal expansion. Sea level rising is due to the amount of the warm water in the sea. Besides that, hot atmosphere causes ice sheets to melt, not just melt from the top down, but also to flow faster into the ocean. We 've already seen a huge increase in the rate of ice loss. Some parts of the word are also experiencing more drought as more water gets carried away from those areas,
Is this program for kids? It is not appealing to hear voices but not see faces and instead we just see some graphics. A poor communication strategy!
Climate change refers to the long-term changes in weather patterns that are observed across different regions of the Earth. These changes are primarily driven by human activities that release large amounts of greenhouse gases, such as carbon dioxide, into the atmosphere, leading to global warming. The effects of climate change include rising sea levels, melting glaciers and ice caps, more frequent and intense heatwaves, droughts, and wildfires, as well as more frequent and severe storms and hurricanes. The scientific consensus is that human activities are the main cause of climate change, and urgent action is needed to mitigate its impacts and adapt to its consequences. activities that release large amounts of greenhouse gases, such as carbon dioxide, into the atmosphere, leading to global warming.

Except any scientist that disagrees is cancelled
The above statement is a manufactured Fraud being used as a political tool.
CO2 is Not a pollutant, it is Not harmful and does Not cause climate change to any significant degree. CO2 is in FACT the most important gas on earth as it is the bases of the entire food chain for all life on the planet.
Our current level of CO2 is dangerously low and we should be doing all we can to increase it. If we can raise the level to at least 2000 ppm, the entire ecosystem will benefit greatly.
And BTW, The term "Fossil Fuel" is a fabrication and a fraud.
None of the beggar countries test nuclear weapons.
That is bollox. Our addition of gases does not make much difference.
While other countries getting more cold
Extreme Weather is what we are facing. If it is climate change then we can predict its pattern.

I do think that what you guys saying is just preposterously ridiculous because in my city the impacts of climate change are quite visible it caused to rise in cancer and other respiratory disease
@rawazardalan2288 I am uncertain of your location and how a small increase in the concentration of CO2 in the atmosphere results in an increase in cancer rates in just your area. There are, however, lots of positive effects associated with climate change. There has been a 10% decline in natural disasters since 2000 (CRED). Normalised disaster losses have decreased since 1990 and human mortality due to extreme weather has decreased by more than 95% since 1920, so you're 50 times less likely to die from a climate-related disaster in a world that's 1°C warmer than 100 years ago (EM-DAT, CRED/UC). Deaths from drought have declined by 99%!
Climate change saved 555,103 lives in England and Wales between 2001 and 2020 (ONS, 2022).
There are over 5 million excess deaths per annum globally due to abnormal temperatures from the 2000-2019 study led Prof. Guo of Monash University. It found that over 90% of excess deaths were caused by excess COLD rather than excess heat. This applied globally including in the hottest continent, Africa. So, in a world with increasingly mild temperatures, there will be less excess death. Warming is good not bad.
One of the main causes of death in the poorer parts of the world is attributable to air pollution. This is because they have to burn wood and dung over open fires for cooking and heating in their homes. These people need access to gas stoves and electricity to improve their health and life expectancy. They need fossil fuels to make them healthy and wealthy.

Do you deny current atmospheric concentrations of CO2 are over 30% higher than they were about 150 years ago at the dawn of the industrial revolution and in the same time span the average global temperature on Earth has increased by about 0.8° Celsius (1.4° Fahrenheit) since 1880. Two-thirds of the warming has occurred since 1975, at a rate of roughly 0.15-0.20°C per decade, roughly ten times faster than the average rate of ice-age-recovery warming?
