 Well, good afternoon. I think the arrival of the dark out there and the light in here suggests the time has come to start, even though we're a minute or two early. My name is Tony Travers from the London School of Economics, and I'm going to chair this session for the next hour and a quarter. This session is called an Urban Response to Climate Change, and we will have a session keynote speaker, Anthony Giddins, who is a member of the House of Lords, an author and, of course, former director of the London School of Economics. Indeed, we have two existing or previous directors of the LSE here. I'm not sure what the collective noun is, but I'm sure it's good and polite. Our first discussant, I should say, is Tessa Jowell, who is a Member of Parliament, Dane Tessa Jowell, and was the Olympics Minister and on the board of the organisation that brought the London Olympics to fruition. Craig Calhoun, the second of the LSE directors, the current director of the London School of Economics, and a leading sociologist formerly at New York University. Enrique Penalosa, former Mayor of Bogota, now President of the Institute of Transportation and Development in New York. Last but not least, Martin Haier, who is director of the Netherlands Environmental Assessment Agency and also an academic. You're all very welcome. The subject for this afternoon, or the early part of the afternoon, is an urban response to climate change. I'll say no more other than the way in which cities handle this issue is clearly a big test, a big current test, of the way they operate. All cities at all times are faced with new issues to deal with, the management, the complex management of new technology, new problems, new people and so on. And with that in mind, there's no doubt that climate change and the way in which countries and particularly cities respond to it is of very significant importance. However, enough from me, our keynote speaker is Anthony Giddins. Tony.
