The BBC's report of a Dutch investigation into the IPCC was that there were "no errors that would undermine the main conclusions". Similar Guardian report here.
Of course there are still deniers. The Times headlined "UN report on climate change was one-sided". The article is behind the paywall and I don't expect you want to pay for it. There will still be deniers in fifty and a hundred years time, it's just that with every passing year they look more and more stupid.
But what I want to know is why is John Redwood, the Daily Express and other assorted scientific illiterates, who complained that this year's cold winter cast doubt on climate science, not recanting now the weather is so hot and dry? They should either accept that 'the weather' is different to 'the climate', or stop cherry-picking weather evidence to suit their views.
