IT was a breath of fresh air to see our MEP, Godfrey Bloom, questioning the validity of the theory of man-made global warming. Coming from a politician, this is indeed a rare and welcome event.No doubt the greens will be along in a flash to pour scorn on Godfrey. Their standard response is to attack the messenger, not the message. Regrettably for them, there is nothing but bluff to back up their assertions. Ask any climate scientist to show you evidence for a visible man-made signal in global temperature data, above the noise of natural variation, and he will not be able to do so. Because there is no signal, anywhere, in any observed data. Predicted man made global warming (sorry, climate change now, isn't it?) exists only in hopelessly flawed and inadequate computer models.Some scientists refuse to make their work available for scrutiny on the grounds that they have invested tens of years in their research, which they will not have challenged. Scientific research has always advanced by scrutiny of existing research, but not in the field of climate research, it seems. The global warming scam is perpetuated to raise taxes, give scientists a nice little earner and provide the old loony left with a bit of influence, having swapped their red flags for green ones.
