Climate Change Act 2008 (2020 Target, Credit Limit and Definitions) Order 2009

My Lords, perhaps I may quickly answer those pertinent points. The big ice melting was about 12,000 years ago at the end of the last glaciation, which greatly increased sea levels. The more recent increases of about seven inches since the little ice age are thought by the experts to be due to thermal expansion, at which I think the noble Lord hinted. As the seas get a little warmer, they expand. At the moment, that is regarded to be the cause and not ice melting, because it has not melted.
