Andrew Bolt gets a perfect score on global warming

Last chance for Bolt.

10: Gore never even hints at other possible explanations scientists have given for the warming globe.

And here's just one: increased solar activity. That's a theory suggested by leading American scientists such as Sallie Baliunas, Willie Soon, Fred Singer and Frederick Seitz, past president of the National Academy of Sciences.

Some even predict we're about to suffer a new bout of global cooling. Says Professor Bill Gray, world hurricane authority from Colorado State University: "My belief is that three, four years from now, the globe will start to cool again."

This one is wrong. For increased solar activity to explain recent warming, there would have had to have been an actual increase in solar activity. RealClimate:

Regardless of any discussion about solar irradiance in past centuries, the sunspot record and neutron monitor data (which can be compared with radionuclide records) show that solar activity has not increased since the 1950s and is therefore unlikely to be able to explain the recent warming.

As for Gray, he says it will cool, but he won't put his money where his mouth is.

Final score for Bolt: zero out of ten. Not just a failure, a miserable failure.
