News on the politics and science of Climate Change.

In science, people are supposed to rock the boat. If someone challenges your findings, you make measurements, check the arguments, and see if they might be right. Well-established theories such as evolution and relativity have survived this process. The ideas you don’t hear about are the ones that didn’t make it through this ordeal by fire.
If you depart too far from this in your desire for consensus, the consequences can be disturbing. The emails from scientists at the University of East Anglia suggest that certain members of the IPCC felt that the consensus was so precious that some external challenges had to be kept outside the discussion. That is clearly not acceptable.
Moreover, this leads to the danger that people will go beyond the science that is truly reliable, and pick up almost anything that seems to support the argument. The dodgy dossier saying that all ice would vanish from the Himalayas within the next 30 years is an example of that. When I heard Dr Pachauri, the head of the IPCC, declare this at Copenhagen last December I could hardly believe my ears. This issue is far too important for scientists to risk crossing the line into advocacy.
However, it’s not all the IPCC’s fault. Climate scientists have been forced into this corner by a disastrous combination of cynical lobbying and a misguided desire for certainty.
people and governments hunger for certainty. The problem is that science doesn’t work that way. Nothing can ever be 100% sure; we use science to draw conclusions about how probable it is.
When cigarette manufacturers paid lobbyists to try to discredit the scientific theory that smoking causes lung cancer, they used the argument that it wasn’t a proven fact. Well it wasn’t then, and nor will it ever be, but would you now bet against it? We have built many successful enterprises by going with the balance of probabilities that science deals us. And in the case of climate change, the scientific probability that the world is warming, and that humans are the chief cause, is overwhelming.
Given all this evidence, it’s ridiculous to say this that human-induced climate change isn’t happening, absurd to say we don’t understand why, and any suggestion that we have nothing to worry about is like making a very bad bet.
We know that we need to decarbonise our economy, so let’s do it. Let’s work to create a new, smart manufacturing sector in this county that is fit to tackle the carbon challenge while stimulating our economy back into growth.
The number of British people who are sceptical about climate change is rising, a poll for BBC News suggests. The Populus poll of 1,001 adults found 25% did not think global warming was happening, an increase of 10% since a similar poll was conducted in November. The percentage of respondents who said climate change was a reality had fallen from 83% in November to 75% this month. And only 26% of those asked believed climate change was happening and "now established as largely man-made". The findings are based on interviews carried out on 3-4 February. In November 2009, a similar poll by Populus - commissioned by the Times newspaper - showed that 41% agreed that climate change was happening and it was largely the result of human activities. "It is very unusual indeed to see such a dramatic shift in opinion in such a short period," Populus managing director Michael Simmonds told BBC News. | |
