At 420 ppm of CO2 with emissions rising to extreme record levels and no solid plans to deal with aerosols or destructive industrial agriculture the question now is can the public see through state-corporate media distortions to force fair emergency action which limits the doom?🧵
1. We're still heading for 2C-3C by the 2050s.
We're somewhere around the SSP2-4.5, SSP3-7.0, and SSP5-8.5 scenarios (IPCC climate report AR6 from 2021).
3. Food systems are responsible for a third of human-caused greenhouse gas emissions
Even if the world stopped burning fossil fuels immediately, global food system emissions could still push global temperatures over the 1.5C warming threshold
4. Progress?! We must support independent media to smash myths spread by corporate journalists/editors for the system changes necessary for any hope of a chance of decent survival.
We're still on track for 2C by the 2040s followed by 3C-5C sooner or later.vox.com/the-weeds/2021…

The best estimates (and very likely ranges) for 2081-2100 in the two scenarios that I believe are widely considered to correspond to our current situation are 2.7C (2.1-3.5C) and 3.6C (2.8-4.6C).
Could another 15-25 years of emissions around today's levels mean 3-4C by 2090?
Nov 2021: A 4.0°C rise could see nearly half of the world’s population living in areas potentially affected by extreme heat stress – a potentially fatal combination of heat and humidity.
We are somewhere around the IPCC's 'intermediate' or 'high' emissions scenarios (or even 'very high'?) which suggests 4C-5C or more by 2100 can't be ruled out.
Only a postgrowth economy could keep us below 1.6C by 2050.
'5.2 °C above the pre-industrial level at present rates of increase would likely result in mass extinction comparable to that of the major Phanerozoic events, even without other, non-climatic anthropogenic impacts'
BREAKING: the percentage of primate species threatened with extinction has risen from 60% in 2017 (75% in decline) to 66% in 2021 (85% in decline) 🧵

'Much has changed over the past 4 to 5 years, and none of the changes benefit primate population persistence.' inverse.com/science/primat…
🧵2. 'Deforestation of tropical rainforest continues, as large agribusiness companies and governments continue to convert natural habitats to monocultures and fragmented and polluted landscapes for products that are consumed by people in a smaller number of rich nations.'
Might 2°C calamity by around 2036-2045 or soon after still be avoided with the correct actions?
We should all be talking about this, but journalists and editors remain silent (particularly on a much feared aerosol 'termination shock') so people generally have no idea.
BREAKING: as both temperatures & CO2 emissions soar towards record levels by 2023 and industrial trawling and mining wreck the sea bed, climate scientists fear the ocean will soon be unable to provide Earth's largest long-term carbon store
🧵1. Abrupt climate change has 'a "worrying" effect' on the ocean's ability to lock away carbon. If global temperatures increase to levels predicted, the ocean 'will not be able to provide what is currently Earth's largest long-term carbon store'. bbc.com/news/science-e…
🧵2. We're heading for 1.6°C-2°C by the 2030s as corporations d governments openly plan together to increase fossil fuel production in the 2020s. We can't survive the ocean destruction being driven by economic growth. A postgrowth economy is the only way.cnbc.com/2021/07/20/co2…
