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!)
I’ve been reading that we are in the beginning stages of a long cold period - part of a cycle that happens like clockwork every 206 years. The sun has very few sunspots - called a ‘minimum’ - though I suspect you already know. We are also at the farthest from the sun in the Milankovitch cycle. Looks like you are right. We might be heading into some very cold weather.
I’m just a 63 year old woman who has been following this stuff. Didn’t know much about any of it until recently. Very interesting. Wish I had taken more interest in college!
