It's 2021 and some very smart people are blithely carrying on as if global warming wasn't accelerating.

The measurement of ocean heat content is considered one of the most effective ways to show how fast Earth is warming, and the world's oceans are 'warming at a rapidly increasing pace'. (2020)

1/ 'At 412 ppm and rising, ...temperature rises of 3-4C are likely now locked in.

"It's like a crazy experiment: 'Let's take that CO2 that took 100 million years to be sequestrated and put it back—instantly, on a geological timescale—in the atmosphere and see what happens"
2/ 'Earth has seen sustained concentrations of carbon dioxide was even higher than 400 ppm, but it took millions of years for those increases to occur.

Manmade greenhouse gas emissions, on the other hand, have boosted CO2 levels by more than 40% in a little over 150 years.'
3/ 'The last time that CO2 hit 400 parts per million (ppm) Greenland was ice free and trees grew at the edge of Antarctica.

..400 ppm was last surpassed 3 million years ago during the Late Pliocene, when temperatures were several degrees Celsius higher'..

News:

* 2020: hottest year ever recorded

* 2021: carbon emissions already rebounding to pre-COVID19 levels

Next:

* 2022: last chance to cut emissions to avoid 2-2.5°C?

* 2023/24: 1.5°C?

* 2025/26: 1.6°C if emissions don't stop rising?

* 2027/28: summer Arctic sea ice goes?
2020 is the hottest or joint hottest year (to be confirmed in a week or two).

"..the monthly data suggests that emissions have almost come back to 2019 levels now.”

As usual this corporate media article refuses to mention the threat of global crop failures as we approach 2C and Arctic sea ice destruction disrupts the jet stream.

1/ Dear Journalists,

Subject: Ecological Ruin

Emissions must stop rising in 2021 for a fair chance of decent human survival.

Emissions must plummet towards zero in the years 2021-2029 for a fair chance of decent human survival.

Emissions are likely to keep rising in 2021.
2/
We are in a profound Ecological Catastrophe caused by the human activities of industrial capitalism. Economic growth has proved to be extraordinarily destructive. Technology will not prevent our predicament from becoming impossible to handle.

3/
Ecosystem collapse is already happening, and not just because of abrupt climate change.

Dangerous Assumptions

1. CO₂ sucking machines will soon work
2. Economic growth isn't destructive
3. Global warming of 2°C won't break us
4. Arctic summer sea ice loss isn't key
5. Permafrost thaw isn't yet a worry
6. Sea level won't rise 0.22m by 2035

THREADs for journalists:
1.
We should work on the assumption that CCS, DAC, BECCS won't work soon, though the IPCC suggests they should be up and running well by now.

This means 'net zero 2050' must be rejected and replaced by 'real zero 2025-2030'.

Thread:
2.
Economic growth is destructive. The economy is causing a mass extinction and the collapse of Earth's major ecosystems. Degrowth looks like the only logical alternative if we want decent survival.

Remember:

1) Earth's ecosystems are collapsing, some uncontrollably

2) 37- 55% of species look set to face extinction in the next few decades

3) horrific 1.6- 2°C of global warming will hit by 2035

And yet...silence.

The Biggest News Story In Human History is being ignored.
"Ecosystem collapse is already happening".

It appears to be too late to stop the destruction of 99% of tropical corals and many major forests like the Amazon, but most scientists say that it is still possible in theory to limit/end the damage. We must try.
Until people are allowed to fully grasp the deeply grim reality of the science, meaningful action which challenges capitalist growth will remain elusive.

'Scientists estimate we're now lowering species at 1,000 to 10,000 times the normal rate'.

Dear Journalists & Editors,

Please find enclosed a first Thread of 10 Threads with peer-reviewed & IPCC science to help you report on key aspects of the rapidly expanding Ecological-Climate Catastrophe.

First up: Arctic Sea Ice Loss & The Polar Jet Stream Crisis

Cheers,
Ben

1. Arctic Sea Ice Loss by 2035 will be one of a number of threats to global food security as we approach or even exceed 2°C at which point the IPCC says agriculture will shift from being at 'moderate' to 'high' risk.

Thread:
2. The ongoing destruction of Earth's forests appears to have lead us to a crucial tipping point.

Tropical Rainforests look increasingly unlikely to avoid collapse in the coming decades.
