The Earth’s “carbon budget” — the emissions that can be released to have a 50% chance of keeping global temperature rise under 1.5°C — is shrinking fast. In 2020, the IPCC calculated the remaining budget at 500 gigatons of carbon dioxide and other greenhouse gases. It is now about 250 gigatons.
Improving the odds to 66% or 80% would cut the budget to 150 gigatons and 100 gigatons, which at present rates will be exhausted in less than three years.
Man, these reports just get gloomier and gloomier huh…

yeah it’s long been a given we’re just shooting for a least-bad here, not 1.5C or probably even 2C of warming. my guesstimate is 2.5-3C, although i’d obviously love to be wrong.

Yeah… climate news is really depressing these days.
