"Further, skepticism does not refute the claim, it questions it."

Fine question all you want, the answer isn't going to change. The fact of the matter is that unregulated greenhouse gas emissions are causing a planetary energy imbalance  and provoking vast changes in the climate system (of which I'm sure you're aware of by now). It will be cheaper to mitigate these changes now than adapting to them later. These are all scientifically non-controversial statements.
