The scientific principles behind CO2 causing our planet to heat up are
very convincing.

Not really: consider that ice core data shows that previous
temperature increases *precede* increases in atmospheric CO2 levels.
Kinda hard to show a cause-and-effect relationship when the supposed
"cause" follows the "effect".

That makes GW still more scary, IMO. The CO2 increase like now
(industrial revolution) has never before occurred (unless there was
indeed volcanic CO2 output).

Is CO2 the worst of the gases? No, methane is much worse, but because
it is present in so much lesser quantities, it may not reach the
importance of CO2.
Is the heating by the increased CO2 that much?

First off, there's *no* evidence that increasing atmospheric CO2
levels *cause* the very slight warming that has been observed...

The papers I have seen in reputable journals like Science indicate to me
otherwise.

On a scale of 0 to a
million degrees Kelvin, again, no, but try heating your body up 5
degrees K, from 310 to 315 degrees. That is not even a 2% increase!
But less than a few hours and you're cooked.

.. and second, this is an entirely specious comparison. The slight
temperature increase that has been observed so far is NOWHERE NEAR 5
degrees Kelvin.

I was trying to make a point, but apparently didn't succeed. The point
was that human life (and society in general) is predicated on
agriculture, which is really bound to a rather narrow temperature range.
You can shift things somewhat to or from the equator, but that's it.

I hope I am just seeing the dark side of things and that it won't be as
bad as the doomsayers suggest, but wouldn't you want to be on the safe
side?
