Amazon Deforestation: The Next Climate Tipping Point?
Vložit
- čas přidán 27. 05. 2024
- The Amazon rainforest is on the brink of a major climate tipping point - a small shift in the climate system that could have drastic long-term consequences for the entire planet. Scientists believe deforestation could cause the Amazon to dry out within the next 20 years, leading to more frequent droughts and lower crop yields across the Western Hemisphere.
Meanwhile, is the Gulf Stream collapsing? The Atlantic Meridional Overturning Circulation is slowing down and is now at its weakest point in at least 1,600 years. Could it cross a tipping point where it shuts down entirely, just like in the Hollywood film The Day After Tomorrow?
And let’s not forget that two massive glaciers in West Antarctica - Thwaites Glacier and Pine Island Glacier - are rapidly melting, threatening the world with sea level rise. If both of these glaciers were to melt, they could raise global sea levels by more than a meter.
In this video, we explain all you need to know about Amazon dieback, the Gulf Stream collapse, the West Antarctic ice sheet, and other climate tipping points.

What do you think it would take to keep global warming below 2°C?
Time travel
I think the key is population and consuming less I don't personally see a way to resolve these two keys tho it's just me
We should execute oil executives and redistribute the profits of the oil industries into clean energy for the good of society and the planet :)
decolonization, give the land back to indigenous people, stop capitalist corporations from over-producing, tax the rich, etc
Put all the forests back
this is so important and has so less fews.. Good video !
Solution: Worldwide boycott of food from Brazil! Boycott to beef, grains, and other crops from those deforestation areas!
The longest tunnel in Europe is 35 miles. Bore a tunnel 10 to 15 miles straight down through non fractured stable rock, and you have super heated steam. Built to scale, with turbines stacked on top of one another, and water recycled, a geo thermal project such as this could supply a city or more. The issue obviously is heat, overcoming the heat until you have an insulator installed. Once done this, with proper maintenance would last centuries and be 24/7. The other issue, is the lack of will, and the meddling of the oil companies who don't won't the competition. My hope is someone will pass this along to some engineering firm who is up to the challenge, especially in Europe.
A big problem in Brazil is certainly the unhindered influx of people into the Amazon basin. All across Brazil in advertisements people are advertised to go into the Amazon where they get land for free. While the Amazon Basin was in the 1970s a place with only several hundred thousands of inhabitants, it is now an area with millions and millions of people. Where there are human beings they want to grow and have space for business and private developments. That's why, if you want the Amazon primeval forest to be saved, kick the people out in the first place. Block the Transamazonica and other big roads all across the basin. Then give the forest time and it will start to conquer back the lost millions of square kilometres by itself.
They already had a sustainable economy from the Amazon without destroying it. It was making more per year, that it is now. Many scientist and biologist s have gone to the Amazon to try to save it, and one of the things they did was to create jobs without destroying the Amazon.
When will the "Americans" return to the UK and allow the regeneration of the incredible North American fauna?
EU ACABEI DE ENTREGAR TEU IP PARA AS FORCAS ARMADAS DO BRASIL AGORA. VOCE ESTÁ SENDO RASTREADO PELO GOVERNO DO BRASIL AGORA.
Yes, and the people who go there are not Framers, they destroy the rainforest and have no idea how to raise cattle, typically 1 acre can't support one cow! they humid heat of the rainforest is replaced with just heat which turns any pastureland into a very hot arid land that will be scrubland in the future, fit for man nor beast. Brazil is the villain here it needs to be stopped and the Amazon needs reforestation before dieback occurs, if dieback does occur then it is game over
What's happening is a modern colonization of native land. Another example of how irresponsible settlers with too much power are the main ones responsible for the worlds problems such as immigration, global warming, human trafficking and many problems they created.
We need to shift to a plant centered diet, moving away from animal meat on our plates.
Or other meat options. Meat doesn't end with chicken, beef and pork.
Agree
more than 40,000 species of plants, 3,000 of fishes, 1,300 of birds, 427 of mammals, 427 of amphibians, 378 of reptiles and of more than 1,25,000 invertebrates. Scientists estimate that in these rain forests there might be at least two million insect species waiting to be discovered and named.
....in Amazon
Sure let's eat the rainforest. You are obviously evil, trying to eat all of those animals food. You should be ashamed. Eat nothing like a truly caring person.
About 7 BILLION LESS People.
You are correct! The HUGE human population on this planet is the fundamental reason for all of the destruction of the Earth that has been accelerating for the past few centuries. If human beings could curb their insatiable appetites for consuming the resources of planet Earth, then even with 10 billion people on this planet there wouldn't be the relentless
destruction of the Amazon and other regions across the planet at the rate that it is going on now. Humans are driven by their base-biology, just like the animals that human beings are, to breed, to eat, to consume. A few million humans on this Earth , their impact would not be so terrible. 8000 million humans increasing to 10 000 million in the next few decades...the planet Earth will experience so much destruction of beautiful regions like the Amazon. I fear the Amazon will not survive!
Save Our Planet Now
My thoughs after watched the video is after deforestation why not try to reforestation or make a outside activity such as, to save our planet. Or make them cut down the only trees that has already have an agreement from forest ranger.
We are well over 508 ppm Co2e (2021 NOAA) which means 2,7C temperature rise if this level is kept long times. This is also backed up with elevated radiative forcing that can be measured reliably. Also noting that even a single unit added to current 1,2C leads to 1,8C. This dimming effect comes from aerosols that are produced while burning fossil fuels (main effect comes from sulphur). We have to stop producing more ghg's and then this 0,6C rushes in. So it is extremely hard to stay under 2,0C. A study in 2021 said we had 5% chance to stay below 2C... And yet still we keep on emitting on record level making ghg situation ever worse.
One thing that you missed is current trend where local forest are becoming sources of carbon. They were sinks before and now many of the forest have became a source. This is really a wide threat and has devastating impacts which in some point are already here. When the ground in many areas become a carbon source it releases its stored carbon to the atmosphere and climate will warm ever faster.
It is not very likely that we could stay under 2,0C. But yet still we has to try.
Stop burning. Stop ALL burning. Today.
Hopefully if there is sea level rise there will be less space for cars, roads and humans.
We need to have the will
I feel as though the most important change we can make right now is incorporating nuclear power to replace fossil fuels, because nuclear power gives off 0 emissions and is extremely efficient. The world is simply not in a state where it can support a switch to full renewable energy on a whim, and we need nuclear power to buy us time for a transitional phase.
Nuclear is very far from clean, you’re forgetting about the front end of the process which burns millions of gallons of diesel in the mining and refining of the fuel for the reactors
@@Medicinnov8r That's understandable, I imagine it takes quite the load to set up.
However, once Nuclear *is* set up, it's very clean. At the very least clean comparatively to what we're doing now, which is burning millions of tons of crap and then moving onto the next pile of crap.
They need to be shut down now as we head into abrupt climate change so what survival there is has a chance...
All over the world we need “sustainable square” / “checkerboard development”
This is where humans live in a village on 1 acre and they’re surrounded by 5 acres of protected land to care for the species.
We need to prove that there are good jobs living this way for example, there will be jobs for researchers to study the species and for tourist to come in. Observe the species and museums about the species and also there is Permaculture (growing some small scale native plants while leaving the canopy up. There can be gardening, maybe playing soccer on half court fields, and table tennis & teaching jobs - through college on site.’
It needs to happen, especially in the South American forest, but we can demonstrate it also in other countries. And plant more trees around the world - and lots of kelp forests too!
here I'm going to leave my comment on another video where they blamed us Brazilians as causing climate disgrace among other things, and also remembering that the richest countries are the ones that pollute the most and besides Germany and Norway that has an "Initiative with a background" Nobody Brazil pays more to maintain the Amazon but everyone says they need it ironic, right?
these videos that serve to deceive the laity, in fact deforestation was higher in the previous governments of Lula and smaller in Bolsonaro's and again it was higher in Lula's government what happens is that, Bolsonaro wanted to explore the Amazon in an ecologically renewable way However, this would end up with some countries that would lose a lot of economic power compared to the products that could leave there, mainly Europe where most of the wood that is smuggled ends up in European countries, as in the Bolsonaro government, trackers were placed on wood that was being smuggled and they ended up discovering their European buyers, squid doesn't care about the amazon he wants the money that foreign countries will give as a way of "taking care" of it through these NGOs that do nothing more than serve as a post for smuggling these materials including gold that in French Guiana an extramarine territory of France is explored without any shame, all Brazilians who they are not alienated by these lies from NGOs they know the truth that foreign countries want to control the amazon so that in the future they can take the precious materials that are in it which, if used by brazil, could transform the country into the most powerful in the world, we have 80% a metal called niobium, and China already exploits a mine because of Lula's previous government, this material is extremely important and, if studied, can be used in several applications, such as more durable batteries, more resistant helmets, etc., these materials are used for aliens. people that we are bad that we don't take care of the forests etc but in fact which other country has a forest as preserved and alive as ours? they are passing the responsibility of taking care of the world to us but we don't even receive the right payment for it they say that we must live in poverty without economic development so that they squander how they can buy different things and the next day throw it away without caring about the environment or how many things were destroyed to make what they discard so easily, the sheer hypocrisy of such countries, Brazilians are already connected to this and will not let us no longer tolerate being slaves to countries that devastated their forests and now squander how they are profiting from their factories polluting the world and enjoying the good and the best while Brazil has to be their "lung" and the people live in poverty, if the elections were not stolen we would still have sovereignty over it but with this corrupt thief possibly he will hand over to foreigners our amazonia and when that happens the people will rise up and there will be a war 10x worse than vietnam where whoever enters alive in the forest he left dead in a coffin.
Another problem with the Amazon is the investments of other countries, the Amazon has a lot of precious stones, water and a great biodiversity (as one of the main materials to make Channel N°. 5 was a leaf that was highly explored. The chance of this financial aid in favor of biodiversity being a mask for financial interests in the future for exploration are great, even more in relation to the water that will end one day. There are other areas in Brasil and other countries with unique biomes and also a lot of biodiversity, but these countries do not appear to link with the loss of other forests and animals, but they care about the one that have gold and a lot of water, this is really weird and suspect.The Amazon must be preserved and the local economy should be supported by ecotourism with a lot of supervision. Nobody in that history is the good guy!!
Getting away from coal and gas as energy sources as quickly as possible!!
Since the ocean takes up almost half of our GHG emissions, wouldn't the most effective way to tackle climate change than be to give our oceans some rest and time to recover by taking out less fish? Like decreasing global fishery by 10% - how much more carbon could be taken up by the ocean and eventually carried down to the bottom for the next couple 100-1000 years?
Only 18% ?
The presenter has not demonstrated what a Hadley cell is. Hadley sells are huge component to Global atmospheric circulation. Hadley cell walls converge over the Amazon rainforest. Hadley cells walls are accelerating away from the rainforest to creating an artificial low pressure front. This low pressure front circles the entire planet. So if you drew a line from the Amazon rainforest and Drew it around the planet, and true and L on a chalkboard and Drew a circle around it and you do that L side by side at the zero degree latitude, that is the Hadley cell walls that are leaving the tropics and are traveling outwards at 30° north and 30° South before the Hadley cell walls converge and compress the atmosphere creating an artificial high pressure front which creates deserts at that Latitude
Wtf is wrong with humans?!
Take care everyone. I love you all. I hope civilization ends quickly for the sake of all of us. Because if it's slow, it won't be nice...
Hope in Jesus has his twicket to the front of the ride. Personally, I don't want to starve, or see other people starve, so I'm hoping he gets here quick.
But look at the bright side Brazil GDP is increasing by deforestation. They could lead a awesome lifestyle.
😮
Not twice but similar to the size of India.
Hi cool right
I love the economic terms used when you talk about the amazon, it's like the average person is too dumb to realize some things are more important than money. smh
The Amazon intact is worth more economically than what they're doing to it now. I'm glad I'm not a scientist, because I'd be p.o.ed.
A lot of money and time was spent trying to save the Amazon, and create a sustainable economy without destroying it. It's a real shame what's happening here.
I think the amount of money and time that was spent on trying to save the Amazon, shows that wasn't important.
I hope you got a B+ or higher from your school teacher for that. Have you heard of David Attenborough.
Holy hell why is everything so negative
If the Amazon cannot be reforested because of human habitats and cities...nations in South Africa with deserts should forest half it and help keep South America with forests...
All living things evolved and will continue to evolve History has shown a pattern of the Earth going through changes dating back to billions of years ago Who’s to say this isn’t an evolutionary period & natural selection process I’m sure Methane and CO2 don’t help our eco system I believe the process regardless is inevitable Still I’ll need do more research on the topic I’m all for saving the Rainforest and boycotting their president!
E O O HISTORICO AMBIENTAL DO TEU PAÍS DE MERDA E O TEU PRESIDENTE NAO DEVEM SOFRER SEVERAS PUNIÇÕES ?
Ice that's already in the water can't raise the water level only ice that falls from land into water can raise it's level am I wrong about this
you're not. Right now it's the front part of the Thwaites glacier, which is in the water, that's in danger of breaking. But even though it wouldn't cause sea level rise if it broke off, it would no longer be buttressing the back, which is on land, so it would soon slide down and break off too. This could happen to the entire West Antarctic ice sheet, and there's a chance we're already committed to it (although it would take a long time).
" So observe the effects of the mercy of Allah - how He gives life to the earth after its lifelessness. Indeed, that [same one] will give life to the dead, and He is over all things competent."
Qur'an 30:50
You will not disappear.
You will not rot under the ground
Who created you from nothing;
He will give body and life again.
Infinite and will have a life worthy of human beings.
Death will be the beginning of eternal life.
1893 bayram
Relying on god to save the world is gonna do nothing.
Downvoted. Came here for the Amazon not glaciers
Human is cused his own death
The whole thing is the most B.S. I've ever seen and heard.
Plant a billion trees a year !
Unfortunately it don’t work like that, Trees take many years to get to maturity an be able to absorb large amounts of carbon. People know what needs to be done, stop the destruction now! yet it’s still ignored.
Find another zone in the world to plant as many trees as the Amazon Rain Forest !
