This is a good point. I try to simply say that this is a complex problem and we need to listen to the climate scientists—they actually understand this stuff. A recent paper by James Hansen suggest that dealing with the issue is even more difficult than we believed. It seems that something related to aerosols have been sharply decreasing the heating effects of C02...but will need to be managed carefully as we reduce C02.

I think Greta still says it best: Listen to the scientists. And we must act NOW because our house is on fire. We have no time for argument or delay.
