Climate Change

My Lords, I am old enough to remember that not long ago we were being warned of a new ice age, so we have to take that into account, too. I have two questions. First, the inexorable growth in world population is estimatedto increase by a further 50 per cent over the next30 years, I believe. Do the Government have any plans to address that problem, because if we do not deal with it, we have no hope of solving global warming? Secondly, will the Government review their policies on airport expansion, particularly at Heathrow and Stansted—and in other parts of the country? Unless the Government do that, aircraft movements will continue to rise and rise and there will be no hope of reducing aircraft emissions.
