The Committee on Climate Change (CCC) says climate effects are already being felt in the UK in the form of higher temperatures and changing seasons. This is the first time the CCC has looked into how homes, businesses and authorities should be changing in order to deal with climate impacts. Previously it has concerned itself with matters like the country's greenhouse gas emissions and energy supply. "The UK must start acting now to prepare for climate change," said Lord Krebs, chairman of the CCC's adaptation sub-committee.
