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".

Yes really. Thermodynamics and molecular spectroscopy provides
that scientific basis, not meteorlogical or geological records.

The greenhouse effect is on a sound theoretical footing. Climate
change is not.

You are confusing causality with correlation--So does Al Gore.


Is CO2 the worst of the gases?

The are neither good, nor bad. Although without a greenhouse
effect the Earth would be frozen solid. That is very easy to
demonstrate *scientifically*.

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...

There is no question that increasing greenhouse gases in the
atmosphere drives temperatures up. There is also no question
that there are many other factors.


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.

Of course he didn't say it was. He was pointing out that what is
a small change in the purely physical sense is important to
us.

But of course you knew that.
