Now, see, it's that kind of "they always say" that I'm talking about. There is no they. At least, not that matter any to the science of climatology or the science of ecology. There are a lot of self-appointed blabbermouths who can safely be ignored, and then there's the science. And that speaks for itself.

So before you say "they this" and "they that", consider the source, then ignore "them". Go with the evidence, not the noise of the crowd.
