,,, despite the fact that I had written a thoroughly well-documented book about global warming (An Appeal To Reason), which happily became something of a best-seller, and the following year founded a think-tank, the Global Warming Policy Foundation (which is advised by a number of eminent scientists), I was never invited on Today to discuss any aspect of climate change.
That was until earlier this year, when I was asked on to discuss the recent bad weather, which had caused widespread flooding in parts of England, the extent to which this may have been connected with man-made climate change, and what should be done about it.
My opposite number was the scientist Sir Brian Hoskins. It was an appropriate pairing, since Sir Brian is no remote and unworldly academic: he is chairman of the Grantham Institute for Climate Change, a lavishly-funded alarmist pressure group, and a member of the Government-appointed Climate Change Committee, which exists chiefly to promote the abandonment of fossil fuels (coal, oil and gas) by the UK.

I'm not sure what there is to debate. Carbon dioxide and other GH gases inhibit re-radiation of energy. Decrease the level of CO2 in the atmosphere and more energy is re-radiated. Increase the CO2 content and more energy is retained in the atmosphere. This is an experiment you can perform in any undergraduate physics lab. The results are predictable and measurable.
The difficulty is predicting how that affects the earth's climate in the short term. There are too many variables.However, as CO2 levels increase, less energy is re-radiated. Ergo, the earth's atmosphere will get warmer.
Carbon dioxide is at best a weak GH gas, almost on the borderline of the definition. (The most effective greenhouse gas is water vapour!)
The simple fact is that there has been no global warming for almost 20 years.
That, combined with the other fact that whatever limitations we put on ourselves will be almost immediately cancelled by what China and India are doing, makes all of this quixotic without evidence that there actually is some global warming.
That doesn't mean that it isn't a good idea to stop putting hot carbon atoms into the atmosphere. But, thanks to all the focus on fictive global warming (particularly in the media) there is no public opinion pressure on politicians to clean up the declining air quality in urban metropolises. And that air is terrible. A simple test: examine the shadows on a sunny day. Their edges are almost certain to be fuzzy. When I was a kid, lo those many years ago, those edges were sharp as a knife edge. The fuzziness is a measure of air pollution.
