ABRUPT CLIMATE CHANGE IS HERE
"The current global growth Economy will definitely take us to unthinkable suffering, death and extinctions at 1.8°C or more of global warming by between 2030 and 2090 unless we achieve profound political and economic system change."🧵

1. 'If temperatures rise to between 1.7 and 1.8C above the 1850s level, then the report states that half the human population could be exposed to periods of life-threatening climatic conditions arising from heat and humidity.'

2. If we get on to a lower emissions pathway in the coming years (emissions are rising towards record levels by 2025) we risk horrific 1.8°C as early as 2030.
Even the best case scenario which few scientists consider plausible may mean 1.8°C by the 2080s.yaleclimateconnections.org/2021/08/key-ta…

3. In reality we can expect 1.8-2C by the 2030s/40s assuming no system change.
1.8C wipes out 15-20% of species even without considering other extinction factors like pesticides, logging, etc

5. Can degrowth system change prevent/delay 1.8C?
Studies suggest it's theoretically plausible (even though we're at 417 ppm CO2!), but even if it couldn't, at least system change would mean the ability to protect everyone from the coming horrors. Today's economy won't do that.

6a. Just to be precise: 'Globally, the percentage of species at high risk of extinction will be 9%-14% at 1.5C, 10%-18% at 2C'carbonbrief.org/scientists-rea…
6b.
Extinction is due to far more than just climate change.
Deforestation, logging, pollution, industrial fishing/agriculture, etc, etc. The whole growth Economy is the threat.
Some calculations suggest 30-50% of species could be gone by mid-century.
