It’s not the absolute global temperature that’s the problem, it’s the rate of change.
Here’s the last 800 thousand years. That massive spike at the end is the problem. It’s had much more CO2/heat in the past, but it’s the rate of change that’s the problem. Here’s the last 70 million years, and it has been higher a long time ago but earth naturally changes pretty slowly at a few different cyclical periods, or over even longer periods of time.
If it increased naturally up to 430 ppm over time (like hundreds of thousands or millions of years), then life would have time to adapt. But it has shot up in less than 150 years and life just can’t evolve or adapt that quickly.
edit: oh I didn’t realize I’m in the Climate community, so people here probably know the above. This is meant for more general communities who may have heard about Fossil Capital’s propaganda but don’t actually know themselves what’s true.
I’m not a member of this community, but it did show up on my “home feed”. While I knew the gist of your comment, it’s good to have a refresher, plus anyone that doesn’t know would be well served by reading it. Thank you for posting it :)
