The Difference Between Climate Change Caused By Humans and Those of Milankovitch Cycles

The Difference Between Climate Change Caused By Humans and Those of Milankovitch Cycles

As I knew would happen, my review of the very serious and heavily documented book, Unprecedented Crime (https://www.paulcraigroberts.org/2018/10/26/global-warming-is-real-the-threat-is-real-ecocide-is-on-the-horizon/ ) resulted in condemnations from the fossil fuel industry’s trolls and from libertarians who think that global warming is a scheme for government to seize more power over private industry. Personally, I wish the fossil fuel trolls and libertarians were correct, but there is scant, if any, evidence on their side. I must say that I am discouraged that the oligarchs’ disinformation campaigns are again taking precedence over fact.

Global warming deniers, which includes honest, non-ideological people, say that the planet has been subjected to many warming and cooling periods, and that it is only natural that the cycles are contining. Climate scientists know this very well, and that is what disturbs them. The fact that the planet has warmed and cooled before does not mean that there is no danger.

Searching around for a simple explanation for readers, I found this report ( https://www.cnn.com/2015/11/06/world/two-degrees-question-ice-ages/index.html ) from a CNN meteorologist in 2015. (Note that the 0.85 centigrade rise in temperature in the report is, only 3 years later, up to 1.1C.)

The real question is: why are man-made greenhouse emissions since about 1880, the onset of the industrial era, more dangerous than those of the Milankovitch Cycles? The answer is: the speed of change.

Here is the gist of the CNN report:

Scientists understand the natural processes behind the previous warm and cold periods that lead to ice ages. They occur in regular patterns called Milankovitch cycles. These cycles occur because the Earth’s orbit around the sun is not constant.
