Media: more growth!
Governments: more growth!
IPCC: more growth!
UN: more growth!

1. There is an alternative: a postgrowth global economy which respects species and ecosystems that secures decolonization and decarbonization with immediate emergency degrowth action in rich countries for the benefit (and survival) of the many not the few.
2. Deforestation must end in the next few years for any hope of a chance of avoiding the near-term collapse of rainforests. This would be possible with international cooperation, but won't happen with the current economic system.
3. 'multiple lines of evidence showing it will be virtually impossible to keep average global temperature rise to 1.5℃ or below this century, without...' theconversation.com/failure-is-not…
but degrowth could still give a chance of avoiding or delaying 1.5C: boell.de/en/2020/12/09/…
4. Chemicals in plastics causing fertility decline & threat of thermal infertility at >2°C. Thread:
5. 'a global climate mitigation scenario that explores the climate effects of limiting global production and consumptions and of envisioning a broader societal transformation to accompany these transformations to reach a good life for all.'
DOOM: majority of scientists think difficult-or-impossible-to-survive warming of 1.9-2.1°C and rising is now unavoidable and set to begin wiping out species within years 🧵
1. 'New assessment warns area the size of the USA will become too hot during extreme heat events for even healthy young humans to maintain a safe body temperature if we hit 2°C' kcl.ac.uk/news/half-a-de…
2. Even before new research confirming warming is accelerating, the overwhelming majority of climate scientists fully expected ~2°C (in most cases much more).
COLLAPSE: scientists indicate all aspects of human societies will be wrecked by 2029-2092 as habitat destruction and pollution intensify with unsurvivable accelerating warming of 1.95-2.15°C and rising now unavoidable even with capitalism's best-case emissions reductions 🧵
"The 2C target is dead, because the global energy use is rising, and it will continue to rise”.. global heating is likely to reach 2C by 2045 dumptheguardian.com/environment/20…
The economy is a heat engine.
How will it cool the planet?
Collapse is already here.
Time to rethink. 🧵

Economic growth: the engine of collapse
The hope is that, with astute academic guidance and sufficiently powerful doses of political will, we can safely navigate our way through the Anthropocene.
But there are physical limits to what is possible.
2.
To get a sense of any physical limits, it helps to look at how physical systems function. A useful concept here is a thermodynamic “heat engine”... available energy powers cyclical motions thereby enabling “work’’ to be done to move something else while giving off waste heat.
COLLAPSE: there is a very high likelihood that capitalism has condemned 2 to 7 billion people to an early death by 2038-2058. 🧵

'At 3C or more of heating by 2050, there could be more than 4 billion deaths, significant sociopolitical fragmentation worldwide, failure of states..'
* 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.
