Apologies for the six weeks blog-oliday. Put it down to Copenhagen blues!

I’m still reeling from the surreal sight of Lord Whacko Monckton (the climate contrarians’ eccentric of choice), captured on Newsnight last night doing an imitation of Al Gore at a public meeting in Australia. Frightening stuff.

Whenever I see Monckton at work, it reminds me just how desperate people must be to have their doubts and prejudices about climate change affirmed by some public figure – indeed, by any public figure at this stage of the debate.

The politics of climate change in Australia are even worse that they are here in the UK. That may well be, paradoxically, because changes in their own micro-climates over the last 10 years have been so much more visible. And painful. And this has polarised the debate about whether these changes are primarily a consequence of man-made emissions of greenhouse gases, or primarily natural climate variability. The end result is that the Australian Prime Minister, Kevin Rudd, might have to call a general election to break the impasse on his proposals for a carbon-trading scheme.

Could it get that bad here in the UK? Very improbably, but the whole tenor of the debate has deteriorated so badly, so rapidly, that it’s now a serious political headache, rather than a minor irritant.

The combination of the ‘climate gate’ fiasco at the University of East Anglia and the growing concerns about the workings of the Intergovernmental Panel on Climate Change (IPCC), broader concerns of the whole peer review process (the so-called ‘Gold Standard’ of scientific research), and the utter failure of Copenhagen has transformed the climate debate here in the UK.

Where they were once thought as contrarian outliers, both the Daily Mail and the Daily Express are now thought to be closely aligned with public opinion. Ed Miliband (the Secretary of State in the Dept of Energy and Climate Change) must be in despair.

So should we be pressing the panic button? I think we should. The damage done to the credibility not just of climate science but also of the UK’s entire approach to climate change is already serious – and getting worse. This could be extremely problematic in the run up to the general election.

So if I was Gordon Brown, I would be asking David Cameron and Nick Clegg to issue a joint invitation to Martin Rees, the President of the Royal Society, asking him to convene a high-level Scientific Panel to comment on ‘the state of the science’ two years from the publication of the IPCC’s Fourth Assessment Report at the end of 2007.

Does it still stack up? What should people make of all these recent revelations? Is the Climate Change Act (to which all three political parties have signed up) still based on robust scientific foundations? Can people still have confidence in the way climate science drives climate policy?

Martin Rees would be asked to recruit three or four top scientists (reflecting different shades of opinion), a couple of business people (like James Dyson or Richard Lambert of the CBI), and a couple of scientifically-literate ‘pillars of the community’ in whom the general public has absolute trust. No NGOs, let alone campaigners!

Give them two months. Bang out a short, sharp report written for lay people, not for scientists. Blitz the media. Run a full-page ad in the Mail and Express for weeks on end – instead of today’s highly questionable ‘Act on CO2 ‘ ads.

Overkill? Possibly. It seems ludicrous that what is still by any standards a rock-solid scientific consensus should have to be shored up by such extreme measures. But if we don’t, might we be looking at an Aussie-style meltdown in public opinion in the near term?
