Quite possibly so.

But I’m selfish enough to care about the impact on mankind, rather than gasping stomata.

IF we can have no effect on climate, and the climate is ever-changing, that’s about the worst case it could be...yet that seems to be what so many FReepers are cheering for. It’s quite an interesting phenomenon.

How are humans going to influence the sun, the ultimate controller of climate? There are variations in orbit, sunspot activity, etc. IMHO, CO2 concentration's effect is minor to insignificant.

Is global warming caused by human activity?

Have you read that article? I found it very persuasive.
