Remember: 1. The oceans are being killed. 2. Forests will soon be gone. 3. Fertile soil is disappearing. 4. Megafauna risk extermination. 5. Insects are vanishing. 6. Climate chaos is inevitable. 7. Extinction is now. 8. Plastic is in our blood. None of this is front page news.

@CaptainAdvance1 The pledges are bullshit and that research is very growth-friendly and capitalist-friendly. Plenty of system change actions we can take but given we're at 550ppm CO2e and extinction is being caused by non-climate factors (eg pesticides) this is a predicament not a problem.

@ClimateBen Those temperature projections are about what is expected based on current pledges if we don't backslide. There are many calls to do so. I agree it is dire. You don't offer many solutions, Ben. What do you make of research that offering agency creates more support than fear?

COLLASPE: a conservative projection assuming action soon to cut emissions would slow the rate of warming (this would still be unsurvivable for 30-50% of species 🤯 - ask IPCC scientists P. Forster, E. Hawkins, Z. Hausfather, etc). 1.41°C 2025 2.15°C 2050 2.75°C 2075 2.96°C 2100

RAPID MASS EXTINCTION: I assume the rate of warming won't go back down to below 0.1°C per decade for at least ~50 years (unless there is fatal abrupt cooling)? That implies broadly unsurvivable 3°C and rising within ~1 to 7 decades*. * regionally from the 2030s, globally 2040s

Remember: 1. primates 2. trees 3. freshwater fish 4. large mammals 5. crocodiles 6. turtles & tortoises 7. high seas sharks 8. island species 9. frogs, toads, newts, & salamanders 10. flowering plants For all of these, a staggering 50-75% of species already risk extinction.

a high-precision age model for the end-Permian mass extinction, which was the most severe loss of marine and terrestrial biota in the last 542 My, that allows exploration of the sequence of events at millennial to decamillenial timescales 252 Mya (2014) pnas.org/doi/abs/10.107…

48-90% of species face extinction * extinction rates: fastest ever * 48% of species: declining populations * conditions to become increasingly extreme given inertia in the: - economy (industrial capitalist/growth; agriculture, energy) - climate system (2.9-5.2°C v. likely)

AMAZING: 48-90% of species now at extreme risk of extinction within decades (not millennia) and.. nobody seems to know

@zmooc @rupephoto True, capitalism with 8 billion industrial vegans wouldn't be sustainable, but first and foremost it's the economic system which creates catastrophic outcomes. 8 billion non-industrial vegans in a culture/economy where nature was the most important thing wouldn't do such damage.

@zmooc @rupephoto Industrial animal agriculture is catastrophic. That's why some relatively very rich people like me end up going vegan. But plenty of humans in the past managed to eat meat without totally wrecking the biosphere.

"They don't eat meat, humans do." Let's take a look at the scientific consensus: the first underlying cause of biodiversity destruction is 'disconnection from and domination of nature and people' through 'colonialism, slavery, modernity, capitalism, and growth-driven economies'.

@ClimateBen Meat is a major driver of climate change and there is no realistic low carbon footprint meat. That also means that blaming capitalism or companies or governments or whatever is rather disingenuous. They don't eat meat, humans do. And they have to stop (or at least reduce). 2/

'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.' nature.com/articles/s4146…

@danmiller999 Haha I assume SRM (Solar Radiation Management?) will be attempted at some point and that it will create new difficulties. 😬

@ClimateBen Ben, I assume you support Sunlight Reflection Methods (SRM) to keep temps from reaching these catastrophic levels?
