See the green dot at the far right side of this graph? That’s where we are today, already descending, I fear, into a major glaciation.
Each bright green dot represents a time when our orbit was the same as now.
Every time – I mean, every time – the orbit was similar to today, temperatures on our planet had already begun a major descent, or were about to.
Each red line represents major cooling.
You can see four times in the last 400,000 years when our planet has been even warmer than today, (so much for man-made global warming!) and many, many periods of major cooling.
I think you will soon see a fat red line (major cooling) added to the right-hand side of the graph.
You may want to look at the above graph*, created by Jan Theart, as you watch the video. (*See note below)
Please keep in mind that the numbers you will see on the video are referring to degrees C.

Note: I included a much simpler version of this graph in Not by Fire but by Ice. That graph, entitled “Pacemaker of the ice ages” was based on global ice volume during the last 500,000 years as determined by CLIMAP isotopic measurements.
