I should say to my noble friend that 95% of people are not held in detention at all. It is used only as a last resort where all the other possible mechanisms for removing people who should not be here have failed. On his point about climate change, I have heard various debates on that. I do not disagree with him that climate change will create more migration effects. However, the weather here over the past few weeks has made me think that people might not want to come here, either, because it is so hot.
