1.6°C by 2030-2050

1. tropics becoming uninhabitable
2. a million species extinct
3. unsurvivable heat
4. corals 90% dead
5. water scarcity hell
6. global food insecurity
7. dire permafrost thaw
8. risk of climate feedback doom

Only a postgrowth economy can aim to avoid this.🧵
🧵1. “On our current trajectory, we are talking about climate change endangering roughly half of all plants and all insect species..

economic growth is just not viable as a mechanism for future prosperity. In fact, it is associated with future cataclysm.”cnbc.com/2021/02/19/deg…
🧵2. The most optimistic IPCC scenario based on a growth economy? Global temperature hits 1.6°C by 2050 then drops back by 2100. Scientists don't think this will happen.

'Such a relatively short excursion above 1.5°C might not trigger the worst outcomes'😱yaleclimateconnections.org/2021/08/key-ta…
🧵3. What scientists actually expect assuming continued economic growth is 1.7°C-1.9°C by the 2040s and 2°C-4°C by the 2090s.

That's 20%-90% of species extinct (assuming mass extinction is confirmed somewhere between 2C and 4C).

Media are quiet on this.
🧵4. Growth economics is driving toxic pollution & habitat destruction such as deforestation to extreme levels. For-profit industrial agriculture/fishing is wrecking the land & oceans. Degrowth is the way to limit warming and stop other non-climatic damage.
🧵5. There is no guarantee degrowth would avoid 1.6°C at this point, but studies suggest it's a possibility unlike with growth which is driving ecosystem collapse and likely results in 2.5C-5C.

Deforestation must end by 2025. This economy won't allow that.insideclimatenews.org/news/18062021/…

1. corals: 90% dead
2. unsurvivable heat
3. water scarcity hell
4. Antarctica collapses
5. global food insecurity
6. a million species extinct
7. tropics becoming uninhabitable
8. high risk of climate feedback doom

Only a postgrowth economy can avoid this now.🧵
🧵1 . Scientists agree: economic growth will make the extinction crisis of habitat destruction, toxic pollution and abrupt climate change difficult for humanity to survive decently, or perhaps even at all

* 1.5°C horrors by 2025-2030

The answer? Degrowth:cnbc.com/2021/02/19/deg…
🧵2. Mass media are virtually completely silent on what is essential for survival: rich countries rapidly and fairly degrowing their economies to aim for survival.

* new scientific consensus:

1.6°C-2.4°C hell by 2050 if we don't progress away from growth.yaleclimateconnections.org/2021/08/key-ta…

Today at >417 ppm of CO2 it seems a clear majority of climate scientists think we'll very likely hit 1.6°C-2.5°C hell by mid-century followed by unthinkable 2.1°C-4.6°C by the 2090s according to the IPCC scenarios which are rooted in economic growth-as-usual. We need degrowth. 🧵

2. IPCC scientists survey:

>75% of respondents said they expect 2.5C, 3C, 3.5C, or 4C by 2100:➡️nature.com/articles/d4158…

1.6C by the 2030s/2040s is unavoidable with economic growth-as-usual.

1.6-2.4°C is hell and with growth it's very likely by 2050:

Remember:

1. the tropics may become uninhabitable if global warming reaches 1.6°C-1.7°C

2. the best case scenarios with economic growth: 1.6°C-1.7°C by the 2040s

3. media refuse to explain the postgrowth alternatives that have been well understood by economists for decades

🧵2. 'The tropics could become uninhabitable if we don’t limit global warming to less than 1.5°C'

We're somewhere between intermediate, high, and very high emissions scenarios: 2°C-2.4°C by 2041-2060; 3°C possible

IPCC unlikely best case scenario: 1.6°C

🧵Dear Journalists & Editors,

Please report that according to the IPCC, the global growth economy will cause extinctions at 1.5°C to 2°C of warming by 2032 then 1.6°C-2.4°C by 2050, but a new postgrowth paradigm could prevent such horror.

This silence is deadly.

Love from,
Ben
1. '6% of insects, 8% of plants and 4% of vertebrates are projected to lose over half of their climatically determined geographic range for global warming of 1.5°C, compared with 18% of insects, 16% of plants and 8% of vertebrates for global warming of 2°C'ipcc.ch/sr15/chapter/s…
2. We can't rule out 2.5°C-3°C by 2050. People must be informed.

* 1.5C by 2027-2035

* 2C in the very high emissions SSP5-8.5 scenario: range of 2032 to 2053

* 1.6C-2.4C by 2050

Remember:

1. this global growth economy will cause climate chaos at 1.6°C-2.1°C by the 2030s/2040s as it

* destroys Arctic ice
* cuts crop yields by 10%-50%
* makes sea level rise surge
* drives 10%-50% of species extinct

2. postgrowth economists show this hell is avoidable🧵

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.
