Did you know state-corporate media are completely ignoring this Aug 2021 peer-reviewed article showing that unless we slow down today's abrupt climate change we may expect a mass extinction equal to the worst in Earth's history within a matter of decades? nature.com/articles/s4146…
'5.2 °C.. at present rates of increase would likely result in mass extinction comparable to that of the major Phanerozoic events, even without other, non-climatic anthropogenic impacts' nature.com/articles/s4146…
'Given the rapid pace of change we've set in motion and without arresting or at least slowing down those changes the record shows that we can expect massive extinctions in the natural world equal to the worst in Earth's history.' skepticalscience.com/news.php?n=5151

'252 million years ago, life on Earth faced the “Great Dying”: the Permian-Triassic extinction. The cataclysm was the single worst event life on Earth has ever experienced.'
1/ 'Insects do not appear to have ever suffered a sudden mass extinction. If the current biodiversity crisis extinguishes diverse higher-level clades, then perhaps humans will have caused insects’ first true mass extinction.' 🧵academic.oup.com/aesa/article/1…
2/ 'However, at present, there are no indications that we are anywhere near a crisis of this severity.'
Really?
What about heading for 2.5°C-5°C of global warming within decades in the context of major eosystems collapsing during a mass extinction event?academic.oup.com/aesa/article/1…
3/ 252 million years ago: the Permian-Triassic extinction.
'The cataclysm was the single worst event life on Earth has ever experienced.. Of the five mass extinctions, the Permian-Triassic is the only one that wiped out large numbers of insect species.'nationalgeographic.com/science/articl…
We'll be approaching 450ppm of CO2 by 2029 which corresponds to 2-4°C of global warming, the end of human agriculture as we know it, and the worst mass extinction in 500 million years, and media, politicians & corporations want us to join them to discuss the role of fossil fuels.
2. "Global warming of 2°C would leave the Earth warmer than it has been in millions of years, a disruption of climate conditions that have been stable for longer than the history of human agriculture.
1. the curve from sperm-decline meta-analysis predicts that by 2045 median sperm counts will reach zero (because of chemicals in plastics) with no evidence the trend is tapering off
2. by 2045 global warming of >2°C may subject humans to thermal infertility
We can act.🧵
1.
We can act on this:
'If you follow the curve from the 2017 sperm-decline meta-analysis, it predicts that by 2045 we will have a median sperm count of zero. It is speculative to extrapolate, but there is also ft no evidence that it is tapering off.'dumptheguardian.com/society/2021/m…

BREAKING: the UN has indicated that with today's plans for economic growth Earth's species will likely suffer profoundly catastrophic global heating of somewhere between 1.65 and 2 degrees Celsius by the 2030s
Where are the appropriate headlines?
There won't ever be any, not in state-corporate media anyway.
Extinction is driven by the whole global growth economy of industrial agriculture, logging, road-building, mining, war, etc
new peer-reviewed science: a temperature increase of 5.2 °C above the pre-industrial level at present rates of increase would likely result in mass extinction comparable to that of the major Phanerozoic events, even without other, non-climatic anthropogenic impacts
journalists:
1.
We're heading for somewhere between 2.5 °C and 6 °C with collapsing rainforests and Arctic sea ice destruction within decades on the current economic growth pathway.
Economic growth can only offer, via deeply implausible future scenarios, an horrific 1.9°C-2.4°C future.
And if best estimates are wrong, it's 2.5°C-5.7°C climate hell.
Only postgrowth emergency action could aim for (still disastrous) 1.5°C-1.8°C.
A thread..🧵
1.
'long-term net-zero targets that have robust plans for reducing emissions by 2030 would reduce the uncertainty in temperatures beyond this year, and could limit heating to 1.9-2.0°C.'
