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…

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).

Destruction of habitats and wildlife has intensified and accelerated to an almost unimaginable degree during the capitalist era. Scientists say the 40-50% of plant species now facing extinction will be obliterated in a handful of decades. It didn't have to be like this. Rethink. Plants are going extinct up to 350 times faster than the historical norm 1. Capitalism: a 'meteorite'

'previous mass extinctions.. took 10,000s, 100,000s, even millions of years to happen. this is happening so fast, now in just two, three decades..'

icymi: our coastal cities will be smashed by multi-metre sea level rise within decades Peak global mean temperature, atmospheric CO2, maximum global mean sea level (GMSL), and source(s) of meltwater. Light blue shading indicates uncertainty of GMSL maximum. Red pie charts over Greenland and Antarctica denote fraction (not location) of ice retreat. The Greenland ice sheet is now losing around 9 billion litres of ice an hour [Geological Survey of Denmark &Greenland]

With the ice sheet at “a tipping point of irreversible melting”, scientists currently expect an unavoidable sea level rise of 1-2 metres.weforum.org/stories/2025/0…

BREAKING: as global warming accelerates wildly normally reticent Establishment scientists begin to discuss plausibility of near-term human extinction 🧵 1/'It seems very unlikely that extinction is on the table for any but the most severe scenarios of climate negligence. However, it is easy to envision a collapse of human civilization.'

What Dr Mann won't say: new papers show 3.5-5°C is entirely likely. gizmodo.com/is-climate-cha…

Has capitalism left it too late to avoid hellish 2/2.5°C of global warming and rising?

Yes.

Can we adapt?

No.

Has the scientific community issued major consensus reports indicating political-economic systems changes are mandatory?

Yes.

Will journalists reveal this?

No.

🧵 The planet you think you're living on no longer exists. This Extinction Economy has set up conditions which scientists fear will prove unsurvivable for the majority of species within decades. Change this Doom-growth system now while it's still too late.
Global warming will happen faster than expected

BREAKING: fears of catastrophe grow as Establishment scientists who organised IPCC's dangerously wrong climate assumptions begin to acknowledge they were wrong 🧵 1. Are Establishment figures really beginning to acknowledge their mistake? Scientists like Hansen, Simons, etc have been pointing out the likelihood of 2°C by the 2030s for a long time, but corporate journalists naturally refuse to investigate seriously.

Irreversible unsurvivable warming:

1.5-1.75°C by 2024-2026
1.75-2°C by 2029-2031
2-2.25°C by 2034-2036

Time's up.

Rethink human systems now to protect species and everyone while it's still too late.

🧵 1.75°C by 2030 State-corporate journalists/editors have ignored the latest climate models for years and years. They've had the information needed to warn the public for decades. Hellish two degrees and rising in the 2030s is nearly here.

System change to try to survive.

Scientists used to think utterly unsurvivable extremes wouldn't hit until 2081-2300 or later (or never). Now they fully expect abrupt global extinction horror by the 2040s. 1. 'What happens in the next two decades will very likely define the future of biodiversity and H. sapiens.' From 2023.

DOOM: For 250 years between 1720 and 1969, the US, UK, & Europe were the main CO2 emitters and the key wreckers of biodiversity. These criminal countries subsequently blocked any attempts to change the deeply entrenched economic system away from deadly capitalism and growth. Share of global CO2 emissions- Our World in Data 1. The US knew by the 1950s/60s that systems change was required to avoid global catastrophe. Scientists informed the President. However, the priorities remained power and wealth.

Earth's species will suffer global warming of 2, 2.5, or 3°C in 12 to 14 years. (No scientist really thinks we won't hit at least 1.96°C for the first time by 2038 after hitting 1.68°C in 2024.) Primates like humans are unlikely to survive for very much longer. Time to rethink.🧵 Headline excerpt : the world will see 3°C much faster than expected 1. "a rise in global temperatures of 3.1C is not compatible with human survival." @jeremycorbyn

New research shows we're heading for rapid mass extinction at 3-5°C of global warming even if we avoid the so-called worst-case scenarios. 🧵 SSP scenarios will result in far more warming than thought 3 to 4 or even 5°C with the 'moderate' SSP2-4.5 emissions scenario.
SSP3-7.0 looks closer to reality to me, so 4-5°C.

The economy is a heat engine.
How will it cool the planet?
Collapse is already here.
Time to rethink. 🧵 1.

Economic growth: the engine of collapse

The hope is that, with astute academic guidance and sufficiently powerful doses of political will, we can safely navigate our way through the Anthropocene. 

But there are physical limits to what is possible.
