There’s Always an Alternative View on Climate Change…..

I suppose that on the day the Government outlines new targets for addressing climate change, it’s inevitable that there would be an alternative view – and there is: from Lord Turnbull in the Daily Telegraph today.

We’ve heard many of these arguments before, but Lord Turnbull discusses them like this:

“First, the science is nowhere near as conclusive as it is presented. Though there is no disagreement that CO₂ is a greenhouse gas, there is no consensus on the relationship between CO2 and temperature. Many scientists also challenge the dominant role assigned to man-made CO2, arguing that other variables such as the sun, cosmic rays, oceans and clouds have been underplayed. Given this, it is unwise of the Government to have placed such heavy bets on just one interpretation of the evidence

Second, there have been failings in the governance of science. Senior figures in our scientific establishment, rather than promoting challenge, have sought to close the debate down and tell us the science is settled. The gap between the IPCC’s huge responsibilities to advise on one of the biggest issues of the day, and its competence to do so, is now so vast that it should be scrapped and replaced.

Third, the framework provided by the Climate Change Act takes no account of what other nations are doing. For a country like the UK, which produces only 2-3 per cent of global man-made emissions, this makes no sense. If we push too hard on decarbonisation, we will suffer double jeopardy: our energy-using industries will migrate and we may still need to invest heavily in adapting our infrastructure.

Fourth, the way in which the policy responses are being prioritised makes no sense. In a logical world, one would start with those technologies that are most effective in terms of cost per ton of CO₂ abated. But the EU renewables policy denies this logic. One set of technologies – in particular, wind – is guaranteed a market share and an indexed price regardless of how competitive it really is. Taking account of wind’s intermittency, its cost per kilowatt hour (kwh) exceeds that of other low carbon sources. Wind capacity should not be confused with output.

Fifth, current policies are hugely unfair. Those with large properties or landholdings on which to install solar panels or wind turbines can earn 30p-40p per kwh, which is retailed at around 11p. The loss is paid for by a levy on all households and businesses. If you live in a tower block in Lambeth, you don’t have much opportunity to share in this.

Finally, policies are failing to adapt to change, notably the impact of shale gas, which can make a huge contribution to carbon reduction with little extra cost.”

Lord Turnbull suggests that “in responding to the advice from the Committee on Climate Change on the next set of targets, the Government has an opportunity for a rethink. Instead, it seems likely that the requirements of keeping the Coalition together will take precedence.”

I don’t agree with Lord Turnbull’s analysis on climate change, though I do agree that there are probably some Coalition politics involved in today’s announcement. It will be interesting to see how the Coalition puts its argument later today.
