Ok, I don't want to get pigoenholed this early into what I hope is a long and illustrious posting history along the lines of "the best bacon sarnie within an hours cruising of hawksbury junction" or "the best improvised device for removing frogspawn from my water tank" but...
Ad hominem criticism is the refuge of the bounder, but Steve McIntyre (of climateaudit) isn't entirely free of Engine Salesman Syndrome. He's worked in mineral exploitation (go Wikipedia) which is an industry generally with a vested interest in downplaying man induced global warming, but I'd heard of him because he was one of the people who attempted to discredit the "hockey stick" graphs of recent climate change. I'm on a little safer ground here, as working with peat, I've come across a lot of work on paleoclimatic reconstruction from peat cores (peat is an excellent record of historic vegetation, and therefore what the climate was like). He found some errors in the way NASA had been calculating temperature averages, which he then used to cast doubt on the whole process (ironic, given that incorrect extrapolation of data from two sources was his main criticism of NASA). However, in the UK, we don't just have to take the word of NASA, as we have some of the best historical continuous temperature recording in the world, so we can look at our own data, from places like the Ratcliffe Observatory or Durham University, and we can draw our own graphs. Plus, I've got 20m of peat core that will give you a fair indication back to the last ice age.
Guess what? It's getting hotter
Which isn't to say it's man induced. The evidence for that is a whole lot thinner. But Warming itself? that's real enough. And Steve McIntyre wasn't wrong. He correctly identified an error and brought it to wider attention. That's how it's supposed to work.
And the IPCC report(s) were peer reviewed by practically the whole US government. Most of it's findings were toned down under pressure from them. The published findings of the IPCC were the least worst scenarios.
Anyway, I've got a big diesel car, a slightly bigger diesel boat and I know what the inside of an aeroplane looks like, but I'm not convinced that hairshirts are the way forward, either. Buy locally, at least read the energy efficiency stats on your next fridge/ cooker before you buy it, and turn the PC off if you're going out. Speaking of which....
