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

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.
The factory food, fossil fuel, and arms industries are all thriving. Cement, plastics, steel.. This capitalist Extinction Economy is the worst-case scenario. It won't stop emissions. It has condemned us to essentially unsurvivable warming at 1.9-2°C and rising by 2029-41. 🧵
1. Mass media journalists are silent on 2°C by 2032-41 as warming hits 1.38-1.5C increasing by 0.35-0.45C per decade.
'12 months after the peak of the El Niño event and global temperatures are still exceptionally high'
BREAKING: World Meteorological Organization issues Red Alert to humanity as accelerating global warming of 1.4-1.7°C and rising heralds essentially unsurvivable conditions within years not decades 🧵
1. The January –September 2024 global mean surface air temperature was 1.54°C (with a margin of uncertainty of ±0.13°C) above the pre-industrial average boosted by a warming El Niño event according to an analysis of six international datasets used by WMO.
BREAKING: scientists hold back tears and shake their heads sadly as they explain utterly compromised COP29 climate conference was meant to be the last chance to organise rapid and deep emissions cuts for any chance of staying well below essentially unsurvivable 2°C 🧵
1. Time has run out to avoid 1.5°C (now sure to hit in the 2020s) and avoid the worst impacts of climate change. 1.75°C will be exceeded soon after with dire 2°C expected by 2030-2050
2. Abrupt climate change is just one compounding factor in extinction catastrophe.
Biodiversity destruction is a core part of the reality of industrial capitalism.
Change this Doom Economy now while it's still too late to protect species and everyone.🧵⬇️
COLLAPSING: scientists confirm there's no doubt humanity will see the real risk of catastrophic multiple breadbasket failures by 2035-2045 🧵
1. “.. we will, certainly, in the next 15 to 20 years, see continued food crises, and the real risk of multiple breadbasket failures … that’s in addition to a lot of the other risks that might impact us through fresh-water pollution, ocean acidification..”dumptheguardian.com/environment/20…

2. even under conservative climate projections predicting a 2°C rise, it is evident that plankton cannot keep pace with the rapid warming we are experiencing, which shows no signs of slowing down'
BREAKING: scientists confirm plastic production is unsustainable and must end as their fears that 30-70% of Earth's species will go extinct this century intensify 🧵
1. “What is clear is we cannot manage the amount of plastic we are producing..Only 10% of it gets recycled, something needs to be done"
