Cold and wet again this weekend on Kangaroo Island. So wet the race club’s major meet for the year had to be cancelled. I guess this proves global warming.

Strange, after all the predictions of drought and heat, you’d think the climate alarmists would at least have the deceny to say ‘Oops. Got that wrong. Sorry. Maybe we ought to look at those figures again.’

But no, Al Gore pops up and says ‘No, really, that’s what we’ve been saying all along.’

Right Al. Right Tim. Sure David.

Then, as if on cue, a study is published in Nature demonstrating a connection between use of fossil fuels and global increases in rain, snow and ice. Based on modelling of selected data. With the assumption that what cannot be explained by what we think we know about natural variation must be caused by us. Roger Pielke Jr has more on why the Nature articles don’t demonstrate any connection between AGW and a purported increase in natural disasters.

But what is really happening? And why?

Mexican geo-physicist Víctor Manuel Velasco has been saying for years that there is no correlation between human activity and global climate change. Based on observations of solar activity, and records of past correlation between solar activity and climate, Dr Velasco says the change we need to be preparing for is an extended period of cold.

Piers Corbyn says the same thing. And his predictions have been uncannily accurate. Predictions from Al Gore/Tim Flannery/David Suzuki and the whole global warming cabal have not.

That is not a small point. Science advances step by step by saying ‘On the basis of the evidence, if this theory is true, then this should happen.’ Then checking to see if it does happen.

If the prediction is not accurate, the scientist looks at the evidence again, and considers whether it matches the theory, and if not, whether the theory might be wrong.

Evidence, facts, observation, trump theory every time. If the theory doesn’t fit reality, it isn’t reality that is wrong.

That is not the way of the alarmists. Their response is to do more computer modelling, to pretend they said something else, to state their views ever more stridently, and if all else fails (and it has) to discredit, abuse and belittle anyone who disagrees with them.

James Delingpole has a few choice examples.

Billions of dollars have been wasted on the global warming scam, and the Australian government is still determined to introduce a carbon tax. A tax designed to slow down the economy, to reduce farming and maufacturing output, to increase the cost of transport. A tax that will increase the cost of every basic commodity.

My school motto was ‘Truth will prevail.’ Even as a teen I thought that was probably wishful thinking.

But in science, truth does prevail. Eventually. Because societies that prefer ideology to science cannot compete in the real world. The USSR discovered this (after immense cost to its people) with Lysenkoism.

The similarities between warming alarmism and Lysenkoism have previously been noted by Australian geologist and paleo-climatologist Bob Carter.

Lysenko, incidentally, denounced real biologists as ‘wreckers’ and ‘people haters.’  He would have called them denialists if he’d thought of it.

Piers Corbyn can have the last word:
