BREAKING: by 2030 Earth's climate is expected to resemble that of the mid-Pliocene going back more than 3 million years in geologic time
We need postgrowth emergency action to limit the damage from abrupt climate change during 20th/21st century capitalism, colonialism, and imperialism.

Explore these threads for more details:

'climates by 2150 could compare to the warm and mostly ice-free Eocene..' (50 million years ago)

"We are moving toward very dramatic changes.."

'whether humans and the flora & fauna we are familiar with can adapt to these rapid changes remains to be seen'phys.org/news/2018-12-h…
We need an immediate shift to a postgrowth global economy to halt catastrophic habitat & ecosystem destruction as well as extinction levels of chemical, light, and noise pollution.

Thread :
Of course, this isn't breaking news at all. The scientific paper referred to above is 3 yrs old. Perhaps unsurprisingly, state-corporate media downplay the climate-extinction crisis. Who grasps 20%-50% of species we love and rely on face extinction by 2050?
The scientific paper doesn't mince words:

'The expected departure of future climates from those experienced in human history challenges efforts to adapt..

Our study suggests that climates like those of the Pliocene will prevail as soon as 2030' pnas.org/content/115/52…

Remember:

1. we're at staggering >417 ppm of atmospheric CO₂

2. aerosols are temporarily hiding the true extent of global warming

3. emissions & rainforest fragmentation are reaching record levels

4. 2°C in the 2030s looms

Ignoring reality makes emergency action impossible.
Scientists are dangerously underestimating the
impact of reducing sulfate aerosol pollution.

Dr James Hansen expects warming rate 'to double in an “acceleration that can be traced to aerosols"

That 'could lead to.. 2 degrees Celsius by 2040'.insideclimatenews.org/news/15092021/…
'Deforestation of the tropical rainforests is progressing unstoppably.'

Accelerated forest fragmentation, at a higher rate than expected, is leading to a critical increase in tropical forest edge area with large amounts of carbon released at those edges.

Economic growth is locking in

1. unsurvivable deforestation
2. >1.7°C global warming hell
3. chemical pollution threatening mammal fertility
4. extinction of 25%-75% of species

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

6 million species:
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.

Remember

1. industrial agriculture
2. deforestation
3. chemical, plastic & light pollution
4. road construction
5. mining
6. industrial fishing
7. logging
8. oil & gas extraction

Media are silent on how economic growth is hurling us into a mass extinction of 75%-90% of species.
Economic growth: a catalyst of overconsumption.

'if consumption continues at the current rate for the next several decades, it can trigger a full or almost full extinction of humanity'

An extraordinary conclusion, but then again this is a mass extinction.en.m.wikipedia.org/wiki/Overconsu…
"If we continue business as usual and we see the same rates of biodiversity loss we've seen over the past 100 to 500 years, we will see the magnitude of loss that was characteristic of the dinosaurs dying out - in a couple of centuries, maybe sooner."bbc.com/news/science-e…

For decades scientists have been saying a vast degradation of habitat and extinction of species is happening on a catastrophically short timescale and effects will fundamentally reset the future evolution of Earth's biota.

BBC News has been all but silent.bbc.co.uk/news/science-e…
'Once-common species will be extinct, or exist only in human-made environments like zoos or private breeding colonies..such as the lemur sanctuary in the Caribbean that Virgin boss Richard Branson proposed last year'

We get scraps of hypercapitalist dross.bbc.com/future/article…
This from the BBC's education section was just a few months ago.

Disgusting.

How might we avoid a global extinction tsunami at horrific 1.5°C - 2°C from 2029? 🧵
1. 'Prominent economists' have explained the need for a "post-growth" plan which necessarily opposes capitalism's pursuit of endless growth, the root cause of today's 'obscene inequality, impending ecological collapse, and climate breakdown.'
salon.com/2021/10/09/sol…
2. 40%-60% of primate, tree, amphibian, and invertebrate pollinator species already face annihilation today due to the ever-expanding destructive activities of the global growth economy. It's not just about abrupt climate change.

Are we all aware 50% of Earth's wondrous species necessary for human survival are in the shadow of mass extinction within 25 years as the endless growth of toxic industrial capitalism thrusts us towards a contaminated 1.5°C Earth by 2027 or is the propaganda too slick for us? 🧵
1. Immediate emergency postgrowth action to radically and totally transform the global economy away from pollution and habitat destruction & fragmentation into a post-capitalist endeavour could yet slow us down and push back 1.5°C by decades or even theoretically maybe avoid it.
2. Scientists say we're in a profound climate-extinction crisis.

Postgrowth action for economic system change is achievable. Positive quirks of fate are a real possibility.

1.5°C-2°C horror in the 2030s may be avoided, IF we warn of the danger.
