Hey, Mike. The truth is inconvenient for Cecil.


Here's the inconvenient truth:

The same thing has happened five times in the past
500,000 years including a few hundred thousand years
before man ever walked the earth. Who caused the
last four global warming cycles?


What are you talking about Cecil? You are presupposing that the "other"
side is saying that all global warming is due to Human activity.

It isn't. Volcanoes can belch out a lot of the stuff. There is a good
chance that methane ice at the bottom of some parts of the ocean can
"let loose" a lot of global warming material.

Of course the obvious answer to your question is "not humans".

And equally of course, the question is not relevant.

There are many answers to your question. No doubt that precession has a
lot to do with it. The Sun itself can vary. I can't imagine that the
Deccan Trap episode of volcanism didn't warm things up after the initial
cooling effect it must have had. Didn't have a thing to do with human
beings.

But your argument has a fatal flaw. That not all causes of global
warming are caused by humans does not mean that none are.
