How do current climate scientists reconcile reporting the relatively slow loss of glacial ice at both poles currently is something that’s unnatural, worrying, proof of humans destroying the planet, a doomsday scenario for life on earth… with the fact that North America was covered by a sheet of ice that was 2-3 kilometres thick only 20,000 years ago. A blink in geological time.
Disclaimer: Yes, human greenhouse gas emissions contribute to climate change etc etc. Yes we should be moving away from fossil fuels. I wholeheartedly agree with all the correct views. But even the most conservative napkin math on the average loss of ice that occurred long before humans were emitting with more than a few thousand campfires globally is orders of magnitude more than we observe now. And that ignores the fact that melt rate accelerates as mass decreases for ice, which would be expected if humans never existed in the first place.
