It is not even up for debate that one of the properties of CO2 is that
it helps retain energy in the Earth's atmosphere (many gases, such as
CH4 - methane - have a greater effect). Increasing the concentration of
CO2 will increase the amount of energy that is retained by the Earth's
atmosphere as surely as night follows day, or as surely as increasing
the burner under a pan of water means more energy goes into the pan of
water. It isn't even up for debate that the concentration of CO2 has
increased particularly in the last century.

What is up for debate is whether we should care, or not. Iowa, in fact,
will be a huge winner in any "global warming" -- but that's beside the
point.

More importantly, all evidence points toward us being able to change/do
precisely nothing about this phenomenon. Given this fact, all the
hand-wringing and whining isn't going to help do anything but sell
newspapers.
