#560ppm
'I added the Hansen line for 10C. You can see 6C for 424ppm CO2 and 10C for today's real-world 560ppm CO2-equivalent (all GHGs) per Hansen's Pipeline paper.'

The consensus view has been with a doubling of CO2 (for modern day that'd be 280ppm to 560ppm), Earth will warm 1.5°C to 4.5°C.

But a new analysis from late 2023 suggests 5°C to 8°C.

At our current 420ppm we are halfway to doubling. So ~4°C may *already* be baked in.

4°C would be catastrophic.

Scientists have produced a new curve of how atmospheric carbon dioxide affects climate. It makes clear that its effects can be long lasting.

CO2 was about 280 in 1850.
Temp was roughly 13.6°C.

At current rate with a best fit polynomial I came up with using Mauna Loa data from 1960 - current, my guess is we hit 560ppm ~2068.

According to link, historically, a DOUBLING OF CO2 MEANS 8°C RISE (so 21.6°C)

2023 temp was 14.98°C

After discussions with the building facilities management, the fresh air flow rates were adapted and the indoor air quality is now excellent in this room.

Super interesting graph!

But I thought we were at around 425ppm, which is bad enough...

560ppm, why?

Ende vom Lied: 1,5 grad dieses Jahrzehnt, 2 vor 2050 und mit schnellen feedbacks irgendwann (angenommen 560ppm CO2 bi net Zero) 4,8 mit langsamen feedbacks 8-10 grad Erwärmung

sehr lesenswert sind vor allem die letzten 2 kapitel (Zusammenfassung und policy Empfehlung von James Hansen)

außerdem müssen nicht auf „net zero“ sondern auf „zero“ also sogar „net negative“ emissionen, die jetzige CO2 konzentratiom von 420ppm (mit anderen THG 560ppm CO2eq) muss runter auf 350ppm wenn die moderne menschliche zivilisation eine zukunft haben will

dh 600mrd tonnen CO2 müssen raus aus der atm
