Here's my sealion of a question. What parts of climate change research are actually backed up by the scientific method (experiments with falsifiable hypotheses and all that) and what parts are more akin to natural history or something else? To clarify, I believe humans caused the problem (it appears that stating this makes people like you more, which is weird, but ok) but I cringe every time I hear the word science attached to the debate. Is it like a social science? I think someone told me that we know for sure that greenhouse gas emissions cause ozone depletion but I can't remember anymore. What is the actual hard science here?
