The global warming theorists were out in force on this site to condemn for me for asking a simple question of Mr Ed Miliband. They accused me of being silly, of failing to grasp the “settled science” and of wasting Parliament’s time and money. The question was “Why is the Northern hemisphere winter so cold, and which climate model predicted this?”. If the question was so wayward, why couldn’t Mr Miliband answer it?
They made a number of false claims about me. They said I did not understand the distinction they draw between climate and weather. Of course I understand that. The point at issue is when does enough weather become climate? When does a succession of cold winters and/or summers affect the averages sufficiently to change the trend? Some used to think that if it got colder – or warmer – for a decade that was “climate”. Now it appears the global warmists think it has to be a trend for 30 years. I hope they remember that if we do have some very hot days for a change next summer. On their own logic that will not be evidence for global warming. They said I do not understand the settled science. Of course I understand their claims, as my blog on the theory makes clear.
So I found it fascinating yesterday that on both the BBC and Channel 4 they decided to run pieces from their global warming experts reaffirming the “settled science” and saying that of course a hard winter is compatible with the theory. At least those commentators graced their audience with saying they could understand why people were asking the question. They thought the question warranted prime time to reaffirm global warming. They attempted to answer it sensibly, making this new precautionary claim that climate takes 30 years to reveal itself.
When I set out a different view of the UK economy – with very different forecasts – from the government’s I do not tell everyone the economics is settled and anyone with a different view is being silly. It so happens my predictions on the course of the Uk economy in the last few years have been more accurate than the government’s. They missed the banking crash and the recession before it was on them, and have been late to accept the inflation they are now creating. They might have been right. You get on and debate the clash of views. Everyone knows that economics proceeds by means of theories that have to be tested by reality. You are as good as your last prediction. Why can’t the global warmists participate in an intelligent debate about when weather becomes climate, instead of making offensive remarks and seeking to close down the topic? The world may be warming – so let’s hear the evidence and find out what difference a cold winter makes to the averages.
As someone unversed in climate change might say ,” Let’s look on the bright side. If this is global warming, we should be very glad we are not facing global cooling. “
