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.

Rapid global warming, cannot be excluded.

⬇️

2. James Hansen warns of dire 2°C by 2040 as carefully explained here by @bberwyn.

Where are the other journalists?

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 Image
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

expect warming rate for 2015-2040 to double 'unless appropriate countermeasures are taken'

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.

Warming: Image
4°C for the first time by 2045 would be utterly extraordinary. However, 4°C for the first time by 2095 looks more and more likely.

Scientsts: global warming of 3°C is

* hard/impossible to survive
* hard/impossible to prevent
* likely by 2069-2092
* plausible by 2045
* just one of many existential threats that mean a total rethink of economic growth is mandatory to protect species and everyone

Journalists:
Capitalism has set up the early deaths of billions of people.

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

Yes.

Has the scientific community issued major consensus reports indicating only political-economic systems changes may end biodiversity destruction and limit abrupt climate chaos?

Yes.
A lot has happened in the past 10 months.

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'

Capitalsim won't 'redouble efforts'.cbc.ca/news/science/2…

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.🧵⬇️
