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".

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...

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.
