“roughly 13,000 years ago, just as the world was thawing from the last ice age”
My pet peeve.
We are still in an ice age that is currently 4 million years old.
The event above was the last GLACIATION, which is when glaciers advance significantly WITHIN an ice age.
We have had 60 such glaciations in the past 4 million years as evidenced by layers of morraine.
Note, after a glaciation, the glaciers retreat significantly (the other half of the cycle).
All occurring naturally without human causes.
Based on the relatively recent activity, you’d expect it to be getting warmer overall now. Just going off averages, we’d be 15000 years into a 33000 year warming cycle, to be followed by another 33 of cooling (presuming we remain in ice age).
And given the fact that ice ages only make up about 25% of earth’s geologic history, you’d also logically conclude that being in an ice age is not the normal state - it SHOULD be warmer.
AND in case you haven’t noticed that there seems to be much more life in warmer climes than at the poles, you’d also want to conclude that WARMER IS BETTER!
. Where did you get that from?
