I thank the Secretary of State for giving way. As he spoke about the regional aspects of the issue, may I ask him to work more closely with his colleague who is currently in the Sahel? There are areas of land, such as Vietnam, with paddy fields that are only about 1 metre above sea level. We are talking about the possible salination of agricultural area, and the consequent massive population movements caused by climate change. I very much welcome the efforts that the Secretary of State is making domestically, but how much is he doing with the embassy network around the world?
