I agree, but must add two comments....
1 Improvements must be economically feasible.
2 Most importantly, Your premise that skeptics are pro-pollution is incorrect.
I will go so far as to say man's actions likely do affect global temperature, however my belief is that this is immeasurable. Much like when you get into a swimming pool, your body heat is absorbed by the pool water, technically this has increased water temperature, but not by a measurable or meaningful amount.
Someone has never been in a pool with a bunch of other people...
Reality doesn't care what you believe.
