Global warming: predicting climate, not weather

leave a comment »

I didn’t realize that some confuse climate prediction with weather prediction until someone’s commet made it clear that it’s worth a note to explain the difference: climatologists study the history and causes of climate, whereas meterologists focus on the weather. Global warming is a climate prediction, and our inability to predict the weather a few weeks from now is irrelevant.

Think of the tide: we can accurately predict the tide, but we can’t accurately predict individual waves.

BTW, a thought occurred to me: we have tended to treat “sea level” as a constant—e.g., the little inset placque on the Denver Capitol steps that marks exactly one mile above sea level. All those measurements will change once the sea level changes. Probably we should use something more stable—e.g., distance from the center of the earth or some such.
