According to scientists, economic growth cannot prevent us exceeding somewhere between 1.6°C and 2.4°C of global warming by the 2040s, when a staggering 20% of species face extinction.
When you listen to the scientists, you realise economic system change is the only way. 🧵

'The most optimistic scenario has global temperature nudging past 1.5°C by mid-century but then dropping back by late century. Such a relatively short excursion above 1.5°C might not trigger the worst outcomes, according to the panel.'
'might not'..

Of course, a lot of climate scientists still cling to the "don't reduce emissions so fast that it disrupts the economy" idea.
But plenty recognise that 10%-30% of species threatened within 25 years by the growth economy signals a need for change.

Abrupt climate change is not the only reason we might consider ourselves in a terrible predicament. Extinction is escalating due to deforestation, logging, road-building, pollution..
Only system change may limit the damage and/or protect us.

Can we avoid >2°C by the 2040s?
Aerosols - the Devil's Bargain - must be dealt with.
