Andrew Bolt gets a perfect score on global warming

Andrew Bolt welcomes Al Gore to Australia with a column that accuses Gore of being "one of the worst of the fact-fiddling Green evangelicals".

Bolt writes:

Well, here are just 10 of my own "minor quibbles" with Gore's film. These are my own "inconvenient truths", and judge from them the credibility of Gore's warnings of the end of all civilisation.

So let's assess Bolt's 10 "inconvenient truths". I'll classify them as either:

1. wrong; or
2. not wrong, but misleading, Bolt having omitted other facts that undercut his position; or
3. a valid point about Gore's movie.

To get a passing grade Bolt needs 5 out of 10. Let's go:

1: Gore claims that a survey of 928 scientific articles on global warming showed not one disputed that man's gasses were mostly to blame for rising global temperatures ...

In fact, as Dr Benny Peiser, from Liverpool John Moores University has demonstrated, Gore relies on a bungled survey reported in Science.

Peiser checked again and found just 13 of those 928 papers explicitly endorsed man-made global warming, and 34 rejected or doubted it.

This one is wrong. Even Peiser has admitted his analysis was full of errors.

2: Gore says the man who first made him realise we were heating up the earth was his late professor, oceanographer Roger Revelle, who noticed carbon dioxide levels were increasing.

In fact Revelle, shortly before his death, co-authored a paper warning that "the scientific basis for a greenhouse warming is too uncertain to justify drastic action at this time".
