BREAKING: catastrophically rapid global warming via an 'aerosol termination shock' in the 2020s and 2030s cannot be ruled out say scientists as they urge immediate media coverage 🧵
1. A recent albedo decrease and increase in planetary heat uptake coincided with a decrease in anthropogenic sulfur emissions.
This trend could accelerate further with more sulfur emission reductions.
3. There’s a fix for at least some of this short-term increase in the rate of warming:
"The only measures that can counteract this increased rate of warming over the next decades are methane reductions"insideclimatenews.org/news/15092021/…
4. Methane is rising sharply
5. The thread is being updated with further details:
6. global warming acceleration is due to the one huge climate forcing that we have chosen not to measure: forcing caused by imposed changes of atmospheric aerosols

7. Scroll up to read this helpful conversation.
Dire 1.5°C can be expected by the 2020s, or if not, by the 2030s.
2°C hell looks hard/impossible to avoid by the 2030s-2060s to my mind, though theoretically it could be delayed for many decades/centuries.
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.
Mass extinction media won't explain why we will hit 2/2.5°C by or before 2040-41. They are part of the state-corporate doom machine and don't want you researching clouds, aerosols, and climate sensitivity. Time to rethink to protect species and everyone.
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.
2. Conservative scientists have insisted for years we should disregard models that show even more extreme warming should be anticipated (and sooner) than the already extreme warming previously expected.
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.
🧵
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.
The Extinction Economy is wiping out life as we know it. 40-70% of species are at critical extreme risk of extinction within a few decades. Abrupt climate change is just one compounding factor in the annihilation of biodiversity and life as we know it.
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.
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.🧵
