How many times does it need to be stated that science does not advance by consensus. Science is not an exercise in democracy. Evidence, yes, but please don't talk about consensus.

I suggest you don't get your science from Discovery magazine or from the Washington Post. This link (from a sceptical website) cites innumerable original peer-reviewed papers showing that even the IPCC now retract on their earlier claims about an increase in extreme weather. You can find many more links to <evidence supported> data on the site.

That said, we should all bemoan the cutting down of forest and the pollution of the oceans to mention only two aspects of man's disastrous activities on our planet.

Why is it a problem to discuss consensus if the consensus is from educated parties and founded on empirical evidence supporting the consensus? Challenging the status quo is fine if you have data to back up your assertions but that isn't what happens in the most case. With the issue being so politicised, data is no longer the ultimate trump card. That's the problem.

Regarding the sources, they're simply the first that I find when I search for information I've previously read and want to reference. I applaud your effort to source thoroughly cited references on points you present, but unfortunately when I'm reading HN between my day job I don't have the same time to build an equally bulletproof case.

FWIW, I don't hold a particular view either way on what you cited. I haven't read it enough. I'm sorry that I can't comment specifically on it.

When people talk about general relativity they don't refer to the scientific consensus behind the theory? It stands up to scrutiny because there are numerous reproducible experiments lending to its validity along with some very solid mathematics to back it up. The science behind climate change is very hard to create experiments for, however, and so we must lean heavily on computer simulated models (which, by the way, are rarely used to prove much of anything in the hard sciences). Thus, you hear a lot more about "consensus" than you would otherwise.
