BIOLOGICAL ANNIHILATION EMERGENCY:
There is 'a common misimpression that Earth’s biota is not immediately threatened, just slowly entering an episode of major biodiversity loss.'
In reality 'the window for effective action is very short'.
⚠️ We cannot keep the current growth economy if we want to survive according to the recent IPBES report and the 23,000 scientists who put their names to the ideas in this paper (academic.oup.com/bioscience/art…) amongst many others...
'If the U.S. and the world are to succeed in limiting disruptive climate change, the U.S. will have to give up the idea that free markets alone can adequately address climate change markets need help from governments'scientificamerican.com/article/withou…
INEQUALITY EMERGENCY:
"A key constituent of sustainable pathways is steering away from the current limited paradigm of economic growth..That implies incorporating the reduction of inequalities into development pathways, reducing overconsumption and waste"
The only decent, workable response 'is energy as a public good, a global decentralised RE energy system, with a massive reduction in energy use together w/ total break up of agribusiness model with food as a right & agro-ecology as model.'
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.🧵
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.. agupubs.onlinelibrary.wiley.com/doi/full/10.10… 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).
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. researchsquare.com/article/rs-607…
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.
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.
'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..' google.com/amp/s/www.cbsn…
2. Current estimates of plant extinctions are, without a doubt, gross underestimates. Extinctions will surpass background rates by 1000s of times over the next 80 years. universityofcalifornia.edu/news/plants-ar…
BREAKING: as tropical forests show increasingly clear signs they are entering a collapse phase scientists warn irreversible mass extinction conditions are on the horizon 🧵
1. rapid warming & collapse
".. warming could continue to accelerate.. even if we reach zero human emissions. We will have fundamentally changed the carbon cycle in a way that can take geological timescales to recover, which has happened in Earth’s past.”scitechdaily.com/mass-extinctio…
2. “There will be a point in the not too distant future when we suddenly see and feel this mass extinction all around us very clearly”
“A key point of extinction crises is that life has always recovered.. However..we most likely won’t be there to see it."
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…
4 to 10 m sea level rise committed in the coming 2000 years, with the majoroty of that in the coming decades/centuries it would appear. science.org/doi/10.1126/sc…
