So, these guys are documenting what appears to be a naturally occurring cycle???

But, we have been told that we need to make drastic changes to our lives, because global warming is man made.

To me, this is just more evidence that we don’t fully understand earth climate cycles. And even if we want to say for sake of argument that man contributes to global warming, we don’t know how much or how significant our contribution is, as compared to naturally occurring phenomena, which we have no control over.

How many ice ages have their been in earth’s history? Previous ice ages did not end because Cro-Magnon Man or Neanderthals were driving SUVs.

Chicago was buried under a mile of ice during the last ice age. All that ice didn’t melt due to Neanderthals running coal fired power plants.

Point is, ice ages came and went due to natural cycles, which we don’t fully understand.

And THEY better not mess with Mother Nature.

If the Neanderthals had SUVs and coal plants, that was no big deal. There weren't that many of them. And the pop growth didn't take off until the industrial revolution.

In 1800 there were less than a billion, now more than 7 billion, and 11 billion by 2100.

At some point, the number of humans becomes such a large force that it exceeds some or all the cyclic forces.
