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🧵

🧵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

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.

Two degrees - which means mass death and mass extinction - will hit from 10 years time in a very high emissions scenario.

Emissions are very high and are projected to rise steeply towards ever more extreme record levels for years.

These journalists will be the death of us all.
1. 'more than 2 degrees Celsius (3.6 Fahrenheit)..Think droughts, rising seas, mass extinctions..Humans never have lived in post-2-degree world..."If we start warming the planet way beyond what humans have ever experienced, God knows what will wait for us"edition.cnn.com/2015/04/21/opi…
2. 'in the very high emissions SSP5-8.5 scenario' the world is likely to pass 2C around '2041 (with a range of 2032 to 2053).'

Some scientists trust government pledges which delay 2C to from 2037 onwards.

No postgrowth system change = 2C by 2030s/40s.

even now, when scientists have clearly communicated that the economy will most likely tip us over dire 2°C of global warming as extinction catastrophe accelerates by 2037-2052, people are clutching at the poisoned security blanket of capitalism

please let go of the myths

please
1. POST-GROWTH

There is an alternative.

Thread on the danger species are in, and possibilities for total change:
2. END THIS VIOLENCE

I invite you to explore a recent @caitoz article and explore the links.

It's very well done - concise and clear!

worth knowing...

1. there's a new scientific consensus: continued economic growth means 1.5°C-2.5°C of crop-destroying global warming & likely mass extinction in 25 years

2. a new postgrowth economy can be created if the public is informed

3. we must support independent media
1. POST-GROWTH
focus on human needs/well-being: reduce inequality, ensure living wages, shorten working week to maintain full employment, guarantee universal access to public healthcare, education, transportation, energy, water, affordable housing

Threads:
2. 6th mass extinction

There's no good reason to think continued economic growth can end habitat destruction or pollution. Over 20,000 scientists put their names to a 2017 paper saying we're in a mass extinction with economic growth a key problem.

icymi: by 2030 or 2040 Earth's climate (temperature _and_ precipitation) is expected to resemble that of the mid-Pliocene, going back more than 3 million years in geologic time, as Arctic sea ice vanishes and sea levels rise rapidly towards levels threatening most major cities 🧵
70% of climate change impact studies show declines in crop yields by the 2030s. Half the studies show horrific 10–50% declines.

A rapid emergency postgrowth transition is our only real option to try to avoid 1.75°C-2°C and >450 ppm by the 2030s.

Thread:
'sea level rise may happen faster than current models project.

The IPCC projects that the sea level will rise about a meter by the century’s end, but this study finds that estimate to be conservative.'

IPCC now accepts >1.5m by the 2090s is possible.
