'Emergency System Change NOW.'


1. Land degradation will hit 79% by 2025
2. Antarctica risks collapse from 2030
3. Arctic sea ice will go by 2035
4. Coral reefs dead by 2040
5. Rainforests dying by 2045
6. 50% species will risk extinction: 2050

Give us screaming headlines.
People in the Global South are dying now.

We need a new economy for ecological/climate justice.

* urbanization and industrial for-profit agriculture are killing the ecosystems needed for survival

* terrifying 2°C of global warming by 2038-2043 is likely
More than three quarters of the Earth’s land areas 'have lost some or most of their functions, undermining the well-being of the 3.2 billion people that rely on them to produce food crops, provide clean water, control flooding and more.'…
In 1978, the glaciologist John Mercer issued a warning: 'If people kept burning fossil fuels at the present rate, he wrote, then within 50 years they could set off the “rapid deglaciation” of West Antarctica'.

Recent evidence shows this is a real threat.…
"We know the Arctic is undergoing significant changes as our planet warms..

The prospect of loss of sea-ice by 2035 should really be focussing all our minds on achieving a low-carbon world as soon as humanly feasible."…
Ocean extinction:

* 90% of corals dead by the 2040s…
'By 2024 the untouched pristine moist forests in their original condition will disappear from Ivory Coast; by 2040, they will be gone from Madagascar, Angola & India, if current rates of deforestation & forest degradation are kept'

(Worse if 2C by 2030s?)…
'Scientists estimate that by mid-century, as many as 30 to 50 percent of all species could face extinction.'…
"there are extreme warming scenarios where 55% of the species would be lost from intact habitats. And note that deforestation also increases global warming. It is a double whammy against biodiversity."

33 - 55% of species to face extinction by 2050s/…
We face 90% of Earth's soils becoming degraded by the 2040s.…

Abrupt climate change and ecosystem collapse will be so severe by 2043 (give or take nine years) that it will be difficult for humans to live.

2°C of global warming 'will likely be exceeded between 2034 and 2052' making it "hard for everyone to live" as an 'abrupt collapse' of tropical ocean ecosystems & forests (by 2030/2050) occurs.………
'Global warming is about to tear big holes into Earth’s delicate web of life..

At the current rate of warming, abrupt exposure events in tropical oceans will begin before 2030 and spread to tropical forests and higher latitudes by 2050.'…

* Ecosystems severely damaged at +1C
* Abrupt extinction events from +1.25C
* Planet's liveability at risk by +1.5C
* Global crop failure fears +1.75C
* Impacts we can't adapt to +2C
* Hothouse Earth zone? +2.25C
* Survival is hard before +2.5C

+2.5C likely by 2050-2075
Ocean extinctions:

'The first completely global bleaching event was in 1998. That was a wake-up call for people here in Australia, because that was the first time ever that the Great Barrier Reef had bleached.'

99% of tropical corals will be doomed at…

Why omit that Bill Gates' Microsoft and mentor Warren Buffett continue to support and massively invest in new fossil fuel production projects?

Why not explain how emissions-slashing net-zero 2030 is less of a fairytale than carbon-sucking net-zero 2050?…
Warren Buffett Is One of the World's Richest Fossil-Fuel Billionaires.…

Ten billion dollar investment in 2020:…
'the firm Gates founded is two years into a seven-year deal—rumored to be worth over a billion dollars—to help Chevron, one of the world’s largest oil companies, better extract and distribute oil.'…

I made a thread of unarguable sources because I just feel we all have the right to know the combined impacts of ecological collapse and climate change during capitalism will likely become so severe by 2043 (give or take nine years) that it will be 'hard for everyone to live'

We need emergency system change now:

Richard Alley, geoscientist at Pennsylvania State University and contributor to multiple IPCC reports:

at 2°C “you are having impacts on most people, impacts on the market, that make it hard for everyone to live.”

We need emergency system change now.

2°C: 'will likely be exceeded between 2034 and 2052 in the highest emissions scenario, with a median year of 2043.'

(scenario of modest mitigation: 2C threshold could be exceeded as early as 2038; median 2052)

Scientsts: global warming of 3.2C is

* hard to survive
* hard to prevent
* likely by 2090
* possible by 2070
* plausible by 2050
* just one of many existential threats that mean a rethink of economic growth is now essential for survival



'for the majority of animals and plants, 3.2°C of warming would mean having most of their habitat wiped out entirely'…
The IPCC & IPBES say we need total economic transformation.

Even ecomodernist scientists who downplay feedbacks and only want policy changes admit 'the world is on course for around 3°C of the end of the century— still a catastrophic outcome'…

You're in a room full of climate scientists. You ask how many think we'll exceed 2C of global warming within decades. You ask if it's possible the carbon 'budget' for 2C has already nearly been used up. You ask whether humans can adapt to all the impacts of well over 2C..


Most scientists expect 2.5 to 6C of warming within decades. These are truly horrific levels of warming happening with virtually unprecedented speed in the history of animal life on Earth.

Guardian policy? Ignore this reality virtually everyday.…

New computer climate models suggest profoundly destructive 2C by around 2043 (give or take 9 years).

These models can't yet factor in all dangerous feedbacks properly so with emissions still rising we can't be sure 2C won't hit as early as…
