While I'm here, I'd like to draw a line under this matter.

Nothing will be enough to quell the warmists' semi-religious fervour.

They are like medieval preachers, proclaiming to baying crowds that the end of the word is nigh.

Given the margin of error associated with the old-style thermometers which were, until only recently, used to record temperatures, it should be stated thus: over the past 100 years, temperature has risen by 0.7C - plus or minus 1.3 degrees!

The only importance the serious scientists can attach to such a figure is that less serious people think it meaningful.

My own science teacher would have kept me in after school for saying this was a valuable figure.

But, as you will have noticed, it worked. The catastrophists piled in - some of whom had previously flourished warnings about global cooling. For some, any figure will do, especially when it gives them a media profile (and grants for research).

Those who worry about facts should look at the findings of NASA (see the website), whose up-to-date and sophisticated global surveys throw such doubt on the warmists' claims
Here's a link for the usual suspects who start bouncing up & down if there isn't one

I know it's the Mail - what else? - so there's no need to bang on about that but the facts of the matter are true.
