Global warming?

My paleoclimatologist daughter has cautioned me about my recent post on global warming. Yes, most scientists agree that climate is warming, she says, but it's impossible to say how much of the warming is due to humans. Maybe 5%, maybe 75%; it's hard to say.

She also suggests that the Kyoto Protocol is a drop in the bucket, and would probably have little noticeable effect on climate. Does that make Kyoto political, as the Bushies say? Maybe, she says.

My own gut feeling is that the recent warming trend is almost certainly human-induced; call it circumstantial evidence. But she's the expert, so let's say "case unproved." We agree that government-mandated conservation can't be a bad thing.
