Climate Change

The hon. Gentleman has been very generous in taking interventions. In principle, there ought to be an objective scientific issue to be debated. Relatively few of us are expert scientists, but what puzzles me about this issue is that it tends to cause alignment on political grounds. I wonder whether he has any thoughts, because he is a thoughtful man, about why it tends to be people of the right who are sceptical about the science. Is it that climate change might imply some sort of collective action, which is anathema to them, so they look for the flaws in the science? That is an important question. Why does it tend to be the right that does not believe the science?
