Though I'm one to question a lot of things and this is my 2 cents. How the hell we know this current changes are completely abnormal? I read about some weird climate anomalies centuries ago and of course there's a lot of evidence that current events are completely abnormal but one question always come to my mind.
What if we're wrong? What if we're being too cooky thinking that by having looked into some evidence that made sense, we're not completely wrong here and current events are just part of a cycle in the planet weather?
Again, I'm questioning but I don't need you guys to present me the proof, I'm aware of it. Just questioning if we're not wrong all along and are here destroying our mental health for nothing. Seems like even by the 1940s standards our generation is being constantly swarmed with problems which we can't fix, which are causing all sort of mental issues due to the complete stress we live in.
This being said, the switch from fossil fuels should be done ASAP, even if we're wrong and it's not causing issues in the environment, they are for sure causing health issues.
For a long time scale, a rapid warming is associated with a rapid increase in greenhouse gases. This causes ocean acidification. Ocean acidification leaves a clear record in the paleontological record. The last one which was comparable to what we're doing through now was https://www.britannica.com/science/Paleocene-Eocene-Thermal-... about 55 million years ago. And current projections for the speed and severity of acidification are worse. Which indicates that the warming that we are going through is also faster than that experienced at any point in the last 55 million years.
