The Amazon Rainforest will be gone by 2029, with catastrophic consequences for all life on Earth.

[Thread]
The Amazon Rainforest could be converted into barren desert *overnight*.

🔺response to rising global temperatures & increased risk of severe drought “non-linear”

🔺Huge risk of hitting irreversible tipping point

🔺Scientific models underestimate risk

State-corporate media have known about climate catastrophe and the death of the Amazon for decades.

Papers like @guardian won't make it sustained front page news.

And it's never on TV.

Only those on social media can inform themselves about this crisis.

The book 'Six Degrees' discusses feedbacks under the heading 'The death of the Amazon':

ncbi.nlm.nih.gov/pubmed/1108996…

It states the Amazon will be 'doomed' over 2°C.

And we will go over 2°C very soon.

Meanwhile, deforestation continues for cattle and feed.
The Amazon Rainforest has experienced three 100-yr droughts in the space of just 10 years.

counterpunch.org/2018/10/26/the…
In the past 50 years, ~20% of the Amazon has been cut down in Brazil.

⚠️If another 20% of the Amazon were to go, that could trigger a dieback feedback loop, in which the forest dries out and burns. The Amazon would devolve into a savannah-like landscape.⚠️businessinsider.fr/us/amazon-rain…
Climate breakdown could speed up the large-scale destruction of the Amazon rainforest and bring the "point of no return" much closer than previously thought.

⚠️ Almost 60% of the region's forests could be wiped out or severely damaged by 2030.

theguardian.com/environment/20…
ALL TROPICAL RAINFORESTS ARE BEING KILLED.

See thread:👇
Amazon destruction from deforestation is at a peak. Desertification at 1.5°C - 2°C will follow as climate breakdown fires cause widespread collapse of the fragmented forests.

Corporate capitalism is killing life on the planet.

68% of the Indigenous lands and protected natural areas in the nine nations encompassing the Amazon region are under pressure from roads, mining, dams, oil drilling, forest fires and deforestation.

60-75% of Earth's species risk sudden extinction in a few decades given:
* extreme population declines
* likely vulnerability of data deficient species
* pollution and habitat & wildlife destruction trends
* accelerating warming of 3/3.5°C in 2-6 decades

Most at risk?

Primates.
Percentage of species at risk of extinction (% with declining populations)

50% (61%) of birds
47% (up to 75%) of amphibians
40% (up to 70%) of plants
40% (up to 89%) of insects
37% (up to 75%) of mammals
28% (up to 63%) of reptiles
24% (up to 84%) of fishes
66% (93%) of primates

Conservative analysis reveals utterly horrific global warming of 1.75-2°C is likely set to hit within 4 to 12 years with truly catastrophic consequences for food systems.
Estimate of 1.44°C (20-year average) warming for 2015-34:

12-40% of species extinct is considered catastrophic. So many amphibian species (~50%), plant & bird species (~40-50%), insect & mammal species (~30-40%), and reptile & fish species (~25%) are currently seen as being at risk. 48% of species are in decline. How will humans cope?
1. under a pessimistic global warming scenario (~4°C increase), climate change alone might only cause the extinction of ~20–30% of extant species in the next ~50–100 years [41,42]. Taken together, these losses would be catastrophic, but very far from 75%.'
sciencedirect.com/science/articl…
2. 'Current projections of future extinction seem more consistent with ~12–40% species loss, which would be catastrophic but far from the 75% criterion used to argue for a 6th mass extinction.'

Some experts fear >50% at 3-4°C even with moderate emissions.

Earth's species will suffer 2-2.6°C and rising even in capitalism's most ambitious decarbonization scenario. Scientists anticipate unsurvivable 3-7°C, with geologic periods like the Miocene climatic optimum (MCO) seen as good analogues for our current 21st century climate hell.🧵 The multimethod, multitaxon pCO2 reconstruction presented here indicates that pCO2 was moderately elevated at ~450–550 ppm during the MCO. These results are somewhat higher than most previously published pCO2 records, which generally report pCO2 < 450 ppm (see Foster et al., 2017), but still considerably lower pCO2 than climate modeling requires to reproduce MCO temperatures (Goldner et al., 2014). This indicates that climate sensitivity must have been elevated during the MCO, leading to highly elevated temperatures at moderately elevated pCO2. With 415 ppm measured for the first time in sp...
1/The race is now on to improve our knowledge of the Earth system in order to understand whether.. moderate levels of pCO2 may.. cause a devastating..increase of up to 7°C in the (near?) future, and if so, take action to prevent it. agupubs.onlinelibrary.wiley.com/doi/10.1029/20… x.com/ClimateBen/sta…
2. The temperature regime reconstructed for most of the Miocene, ∼5°C–8°C above modern, is equivalent to projected future warming in about a century under unmitigated carbon emissions scenarios.. an important warm-climate analog..

COLLAPSE/EXTINCTION: scientists fear global warming of 3.5°C, which wipes out 33-70% of species (IPCC AR4 2007, IPCC AR6 2022), will likely hit by the 2060s give or take a decade or two 🧵
1. IPCC scenario SSP3-7.0 shows 3.5°C by 2080 or from 2062 (not the worst-case scenario). Even a moderate emissions scenario can lead to 3.5°C this century (new research shows 2060s-80s possible).


Species extinct IPCC:
3.5C 40-70% 2007
3C 29%, 4C 39% 2022esd.copernicus.org/articles/12/25…
2. A new pre-print from highly respected climate scientists implies 3.5°C by 2065-77 at current rates of warming. The authors warn this rate could increase or decrease perhaps suggesting 3.5°C by around 2055-2087 rather like IPCC high emissions scenarios.

BREAKING: scientists say Earth's major systems are undergoing abrupt changes — and soon we'll all feel them 🧵
1. 'prepare for a future of abrupt change.. choices made now will determine whether we face a future of worsening impacts and irreversible change or one of managed resilience to the changes already locked in.' phys.org/news/2025-08-s…
2. Society must now brace for catastrophic impacts.
