With UK climatologists now generally on their best behaviour on the subject of a possible link between extreme weather and global warming, Channel Four news seems to have struggled to find someone credible to push the green line. They seem eventually to have persuaded the weather forecaster Michael Fish to give the sermon and you can see the results below. The line taken by the great man was, in essence, that although all the science has been unable to identify a link (unsurprising since there appears to be no actual evidence of adverse changes in weather extremes to explain), he could feel the causation in his water.
Strewth.
