I'm not going to start making sandwiches just yet.
The last geology history book I read recently put the recurring frequency of that sort of sea level change at a minimum of 3 million years...
I don’t know if that image link will be clickable - but it shows the previous warm periods for the last 450,000 years. 25,000 years ago there was the mile of ice over Chicago (and Seattle, etc.)
This current warm period that we are in has lasted longer that the previous ones - so just based on cycles being somewhat consistent (the chart shows that they are) - I’m guessing we are due. Just my simple-minded view of looking at it - who knows what else goes behind it all. These cycles weren’t around for millions of years prior - when the earth was just warm. So beats me why things changed - I suppose earlier there was more volcanic activity (releasing heat) as the earth was still in its growing pains or something.
So perhaps something else has changed now that will make the earth a reasonable 65 degrees average forever from now on. (Ha!)
