2025: emissions reach record levels due to ecosystem-wrecking economic growth just as Earth's species are hammered by ultra-dangerous 1.5°C
2021: there is an alternative 🧵
1.
The chance of reaching 1.5 degrees Celsius of heating by 2025 has “roughly doubled” compared to last year’s predictions and now sits at 40%. gizmodo.com/were-speeding-…
2.
'If countries meet their net-zero and other new climate goals..fossil-fuel emissions would peak by 2025 and then start to rapidly decline..
Despite a peak and decline..the world’s climate pledges still falls well short of..1.5C'
Limiting global warming to 1.5 °C would prevent most of the tropics from reaching extreme wet-bulb temperatures of 35 °C, 'the limit of human adaptation.'
5.'the US is unjustly consuming energy at the highest rate..not simply for the conservation & reproduction of life, but for non-productive expenditures such as luxury & war. Therefore..socio-ecological transformations that we must make must start in the US'theecologist.org/2020/jun/12/de…

2. 'estimates show all scenarios reaching 1.5 ∘C of warming.. in the second half of the current decade.. The warming level of 2 ∘C of warming is reached as early as 2039'
Unchecked conomic growth would mean 1.6C-2C catastrophe in the 2030s/2040s.
'To pave a square meter is a crime against humanity, at this stage of development'
Do schools, universities, state-corporate media ever reflect on slowing down? Do we understand energy? Do we even acknowledge extinction? Are we applying reductionist thinking to living systems?🧵
1. I'm introducing Jeff's thread here, not one of my own, and I'll add a few other comments too below.
How many journalists and teachers examine our predicament in a helpful way? I find it challenging to say the least.
1. economic growth means hellish 1.6-2°C by the 2030s (worst case scenario) or by the 2040s (best case) making parts of the world uninhabitable as agriculture teeters on the edge
2. an alternative economic system is ready for implementation
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.
Previously unconvinced scientists acknowledge the new research
"the actual scientific evidence..until fairly recently, has been pretty weak. This new study does add an important empirical data point into the ‘a relationship probably does exist’ column"
1. scientists say processes like permafrost thaw can trigger 3°C-5°C of warming to confirm one of Earth's worst ever mass extinctions even if coal use doesn’t rise
2. they urge epic 2020s action on gas & oil warning of impacts by 2037-2051 we just can't adapt to🧵
1. State-corporate media have been sidelining scientists warnings of impacts we can't adapt to at catastrophic 2°C of warming for years, even decades.
'There’s a lot we can’t adapt to even at 2C. At 4C the impacts are very high and we cannot adapt to them'theconversation.com/ipcc-expert-wr…
2a. 'Many scientists argue that even if coal use doesn’t rise in a catastrophic way, 5°C of warming could occur by other means..'
