“The change that’s now going on is very strongly concentrated in the Arctic. In fact in three respects, it’s not global, which I think is very important. First of all, it is mainly in the Arctic. Secondly, it’s mainly in the winter rather than summer. And thirdly, it’s mainly in the night rather than at the daytime. In all three respects, the warming is happening where it is cold, not where it is hot.


The people in Greenland love it. They tell you it’s made their lives a lot easier. They hope it continues. I am not saying none of these consequences are happening. I am just questioning whether they are harmful.

There’s a lot made out of the people who died in heat waves. And there is no doubt that we have heat waves and people die. What they don’t say is actually five times as many people die of cold in winters as die of heat in summer. And it is also true that more of the warming happens in winter than in summer. So, if anything, it’s heavily favorable as far as that goes. It certainly saves more lives in winter than it costs in summer.

So that kind of argument is never made. And I see a systematic bias in the way things are reported. Anything that looks bad is reported, and anything that looks good is not reported.

A lot of these things are not anything to do with human activities. Take the shrinking of glaciers, which certainly has been going on for 300 years and has been well documented. So it certainly wasn’t due to human activities, most of the time. There’s been a very strong warming, in fact, ever since the Little Ice Age, which was most intense in the 17th century. That certainly was not due to human activity.

And the most serious of almost all the problems is the rising sea level. But there again, we have no evidence that this is due to climate change. A good deal of evidence says it’s not. I mean, we know that that’s been going on for 12,000 years, and there’s very doubtful arguments as to what’s been happening in the last 50 years and (whether) human activities have been important. It’s not clear whether it’s been accelerating or not. But certainly, most of it is not due to human activities. So it would be a shame if we’ve made huge efforts to stop global warming and the sea continued to rise. That would be a tragedy. Sea level is a real problem, but we should be attacking it directly and not attacking the wrong problem.”
