you'd like to point to one time in the millions of years Earth existed that the environment stayed constant

happy to oblige. for the last half hour the temperature outside my office hasn't changed as far as my sensor can detect.

but of course your request is a bogus & irrelevant one. the question is whether this change is happening to a great extent because of human activity & whether we can do anything to lessen its results.

Dear Tench:

During the early Jurassic era, the climate was warm without any ice cap at either pole. All of the land was one big supercontinent. Think mostly tropical over the all the land. That lasted for many millions of years. Global average temperatures were higher than they are now.
