It is a real shame that the start of the Copenhagen summit will be partly overshadowed by the silly controversy about
the leaked e-mails from the University of East Anglia.
To the climate change denying mischief-makers, this story was gold dust. They found initially plausible evidence that the whole idea of climate change was being made up by a secret cabal of scientists - to what end, who knows! However, to anyone with any knowledge of practical science, there is simply no story. The UEA e-mails change nothing - man-made climate change is
real and urgent.
The seemingly incriminating e-mails are refer to statistical approaches to correcting the raw data that they were analysing for a variety of known errors and quirks. Yes, they are written in offhand language. Yes, they look a bit silly when taken out of context. But they also look like dozens that I've sent in my 'real life' occupation as an academic. When I am analysing data I often talk about 'playing with data', 'fixing data', 'having a fiddle', 'trying a little trick', 'slicing and dicing', 'separating sheep and goats' and so on. It doesn't mean I'm making stuff up. It's just silly stats slang! In particular, it's something I do when I am e-mailing people less numerate than me as if I explained what I was doing properly, they probably wouldn't understand it. Thankfully, my casual e-mails aren't the subject of Freedom of Information requests and they aren't posted on the internet.
There is a great demolition and explanation on the
New Scientist website. Even if the UEA were falsifying evidence (and
it does happen in science and academia occasionally), they are only one small piece in a worldwide agreement about climate change. It wouldn't make it a sham or a lie, as Daily Mail journalists and Saudi Arabian politicians say. It would be a small group of fraudsters in a big pond of good scientists. But there is no evidence that this is the case anyway - just scientists doing their jobs.
One of the major challenges of dealing with climate change is that we are all (and especially us politicians) very reliant on scientists. The basic concept is simple and compelling, but the detail is mucky, complex and often contradictory. Scientists with different views are pitched against each other in the media and this is used by those with a denial agenda to undermine climate change - and the whole of science. Barely a day goes by without a story about one scientist disproving another's work... so who do you believe? But the key thing is that if you asked climate scientists the simple question of "Is our climate changing and is it caused by humans?", over 95% would say "yes" twice.
There is, of course, a chance that the vast majority of scientists could be wrong - it's
happened before. Maybe. But with this issue, the perils of a false positive are more than outweighed by the false negative. It must be better to do something
now than to wait and see and find it's too late. Especially when the 'doing something' is simply about good housekeeping of the planet anyway. And, as someone pointed out to me the other day, even if you deny climate change, we will run out of cheap fossil fuels in my lifetime and that is undeniable. By definition, they are finite.
I do confess to having two climate change heresies that will anger purists. Firstly, I believe in the Great Technological Solution. I think humankind will solve climate change and find ways of maintaining our standard of living without some of the catastrophic shifts that some commentators predict. As a species, we have solved countless big problems before and I see no reason why we won't this time. Secondly, we're actually overdue an ice age, which could make all this stuff irrelevant anyway! Predicting ice ages is a pretty imprecise science and we might be 5,000 years either way. Maybe we're actually in an ice age already, but global warming has overtaken it. Something in the back of my mind tells me that humankind will need to turn its attention to warming the place up in the next little while (in geological timeframes). Our planet is in a '
Goldilocks zone' for life and it doesn't take much in either direction to disrupt the
status quo. In the long game, humans are going to have to become adept at managing global temperatures lest we go the way of the 95% of species that have ever lived!
But I might well be wrong on either or both of these - and in any case, neither are a reason for not believing the science on climate change and not acting on it now. The stakes are just too high.
