"Anthropogenic global warming", on the other hand, is a different beast altogether. It began as speculation in search of facts, or put another way, a bias in search of confirmation. It doesn't seek to explain a past, but to predict a future. It also has the unfortunate feature of being a warped political justification for increased wealth confiscation - something all States fundamentally seek to gain. And wouldn't you know it; the State is the single biggest provider of grants and funding research (confirmatory only) into the potential goldmine. "The end is nigh... unless you pay up!"
Is this like the relationship between CFC output and depletion of the ozone layer? You know, where the EPA, and then finally the Montreal Protocol reduced CFC output. All those damned money grubbing scientists getting grants from the nasty governments, showing the detrimental effects of CFCs, and then, god forbid, the passing of regulations which, ahem, reduced CFC production?
Sounds exactly the same to me.
