Man-made global warming started with ancient hunters

The econuts think that primitive man was closer to Nature and therefore whatever he did was the right thing to do because he was a Natural Man and they believe, an environmentalist.

Allrightie, then.

Why did they want to wipe out the mammoths? They must have known something, way back in their beady little minds the amygdala was telling them—”Kill off the mammoths and you can rule the animal kingdom.”

We are about to ressurect mammothdom by cloning them from finds found frozen in the tundra. You watch, we will become a live Japanese monster movie. Mammothzilla is on the way.

We’re doomed.

mammoth flu will wipe us all out.

Then, as now and ever, variations in solar radiant energy flux dominate the earth’s temperature and its trends.

That's certainly part of the formula. But you have to also add in variations in Earth's orbit over time, axial precession (Milankovitch cycles), ocean currents, etc. See: Milankovitch

The planet has gone through many glacial/warming cycles and the human race only really began to prosper during the most recent interglacial warming period. If our species survives long enough (I have my doubts) we'll be challenged, like the Neanderthals, to adapt to a new glacial cycle.

My only point is that the sun, the source of virtually every calorie of heat energy that warms our planet and its atmosphere, cannot logically be set aside and ignored when constructing a mathematical model to be used for temperature predictive purposes, as I’m told the United Nations Inter-Governmental Panel on Climate Change did. Certainly other lesser influences exist and should not be ignored.
For example, solar cosmic ray emanations, which vary in intensity over time and are thought related to sunspots, are believed to interact with water vapor at very high altitudes to create a layer of thin, wispy clouds that may exert a shading, cooling effect, would be another potential cause of variations in the earth’s temperature.
