BREAKING: world's scientists show that without immediate, total system change the activities of the global growth economy will lead us to mass death and extinctions by around 2045
🧵 1. It's not too late to totally change the global system hurtling us into mass extinction (as >20,000 scientists warn) by rapidly expanding the growing movement for a postgrowth economy to avoid a dead world of ruined habitats, but media remain silent.ecowatch.com/warning-to-hum…
2. 10%-20% of plants, insects, fish, birds, and mammals face extinction at 1.6-2°C due to abrupt climate change, but more species are also threatened by the habitat destruction & pollution of the global growth-inequality economy.

We can act.

3. IPCC scientists' best estimates based on continued economic growth:

Horrific global warming of

1.6C 'by mid-century' (extremely optimistic scenarios)

'2C somewhere between the early 2040s and early 2050s' (realistic projections); 2032-2039 possible.carbonbrief.org/analysis-what-…
4. Mass death of species has already begun at 1C-1.4C of warming, and will become far worse. It's painful to acknowledge this, but more painful and damaging to deny it or remain silent.

Not mentioning climate change until paragraph 17: typical downplaying.cbc.ca/radio/thecurre…
5. Billions of children, women, and men, especially in the Global South, oppressed & exploited by poverty, face atrocious dangers in the 2020s/30s and beyond. We must and can have total change to protect everyone.

Media rarely share the POSTGROWTH answer:cnbc.com/2021/02/19/deg…
6. IUCN: 20% of species in danger of extinction in 2020s-40s; scientifically undeniable we're on path of 6th major extinction
frontiersin.org/articles/10.33…

'western, white and elitist framing of reality' 'centuries of European colonization and fossil capitalism'frontiersin.org/articles/10.33…
7. Mass mortality events have been becoming more frequent and increasing in magnitude for decades.

We must acknowledge mass deaths of the very recent past, present, and the near future at 1.6-2C to limit damage.

This must become context for all reporting.cbsnews.com/news/mass-anim…
8. State-corporate media unsurprisingly ignore the fact that the whole global economy must be totally changed as this would threaten profits and extreme wealth. Abrupt climate change is a staggering threat, but the entire system must change for survival:

9. The US, Canada, and Russia are major food producers, as well as being the countries with most of the Northern Hemispheres permafrost which is beginning to thaw.

And these countries are the fastest warming.

We need to:
rethink energy
build agroecology
10. A rapid, postgrowth, political-economic-system-change transition to tackle utterly unsustainable overconsumption by the ultra-wealthy/affluent is possible. We must be informed why this is necessary, though. It means breaking media silence.

Info thread:
11. A 1998 American Museum of Natural History poll found 70% of 400 biology experts agreed Earth is in one of its fastest mass extinctions threating humans and 20%-50% of species by 2027:

Mass media are silent 99.9% of the time:

Destruction of habitats and wildlife has intensified and accelerated to an almost unimaginable degree during the capitalist era. Scientists say the 40-50% of plant species now facing extinction will be obliterated in a handful of decades. It didn't have to be like this. Rethink. Plants are going extinct up to 350 times faster than the historical norm
1. Capitalism: a 'meteorite'

'previous mass extinctions.. took 10,000s, 100,000s, even millions of years to happen. this is happening so fast, now in just two, three decades..'
google.com/amp/s/www.cbsn…

Recovery: "we most likely won’t be there to see it"..
discovermagazine.com/earth-is-on-th…
2. Current estimates of plant extinctions are, without a doubt, gross underestimates. Extinctions will surpass background rates by 1000s of times over the next 80 years. universityofcalifornia.edu/news/plants-ar…

BREAKING: as tropical forests show increasingly clear signs they are entering a collapse phase scientists warn irreversible mass extinction conditions are on the horizon 🧵
1. rapid warming & collapse

".. warming could continue to accelerate.. even if we reach zero human emissions. We will have fundamentally changed the carbon cycle in a way that can take geological timescales to recover, which has happened in Earth’s past.”scitechdaily.com/mass-extinctio…
2. “There will be a point in the not too distant future when we suddenly see and feel this mass extinction all around us very clearly”

“A key point of extinction crises is that life has always recovered.. However..we most likely won’t be there to see it."

icymi: our coastal cities will be smashed by multi-metre sea level rise within decades Peak global mean temperature, atmospheric CO2, maximum global mean sea level (GMSL), and source(s) of meltwater.  Light blue shading indicates uncertainty of GMSL maximum. Red pie charts over Greenland and Antarctica denote fraction (not location) of ice retreat.
The Greenland ice sheet is now losing around 9 billion litres of ice an hour [Geological Survey of Denmark &Greenland]

With the ice sheet at “a tipping point of irreversible melting”, scientists currently expect an unavoidable sea level rise of 1-2 metres.weforum.org/stories/2025/0…
4 to 10 m sea level rise committed in the coming 2000 years, with the majoroty of that in the coming decades/centuries it would appear.

BREAKING: horrific worst-case scenarios firmly back on the table as scientists confirm large-scale Earth systems such as forests, ice sheets, and ocean currents may already be collapsing 🧵
'large-scale Earth systems may be experiencing gradual collapses that are easy to miss, with profound implications

"we may already be crossing tipping points without realizing"

Slow changes can be deceptive

some systems may slide into collapse silently'

BREAKING: as global warming accelerates wildly normally reticent Establishment scientists begin to discuss plausibility of near-term human extinction 🧵
1/'It seems very unlikely that extinction is on the table for any but the most severe scenarios of climate negligence. However, it is easy to envision a collapse of human civilization.'

What Dr Mann won't say: new papers show 3.5-5°C is entirely likely. gizmodo.com/is-climate-cha…
2/We know relatively low levels of warming like 2 or 2.5°C (which are in fact absolutely extreme given the rapid rate of change) could mean human extinction. Dr Mann would agree 2.25-3.25°C is likely/very likely to hit in a few/handful of decades.

BREAKING: climate scientists say it's now easy to envision a collapse of human civilization 🧵
1. it is easy to envision a collapse of human civilization:

'Without even appealing to the uncertain science of climate tipping points, the known impacts of climate change.. would be more than adequate to destabilize our societal infrastructure.'
gizmodo.com/is-climate-cha…
2. Climate scientists project 2°C and rising by the 2030s/40s, with 2.5°C or more by the 2040s/50s or soon after. There is no evidence whatsoever humans can survive that rate of change and the abrupt shift to extreme new conditions.

2-4°C is very likely.
