Using an online "weather generator", people will be able to see what the project forecasts for their postcode at different points in the future. Using a range of online tools including a "weather generator", people will be able to enter their postcodes and see projections of how conditions are likely to change within 25 sq km grid squares at different points in the future.
"[This is] the most comprehensive set of probabilistic climate projections at the regional scale compiled anywhere in the world," said John Mitchell, director of climate science at the UK Met Office, which has taken charge of the computer modelling of climate used in the report."[This is] the most comprehensive set of probabilistic climate projections at the regional scale compiled anywhere in the world," said John Mitchell, director of climate science at the UK Met Office, which has taken charge of the computer modelling of climate used in the report.

"It's great that the government has decided to put together such a scientifically robust analysis of the potential impacts of climate change in the UK, but the picture it paints is an alarming one," said Keith Allott, head of climate change at WWF-UK."It's great that the government has decided to put together such a scientifically robust analysis of the potential impacts of climate change in the UK, but the picture it paints is an alarming one," said Keith Allott, head of climate change at WWF-UK.
"This research confirms that not only is climate change already having a serious impact in Britain, but that we are also locked into further impacts, and that these impacts will get much worse unless we act now to tackle the problem.""This research confirms that not only is climate change already having a serious impact in Britain, but that we are also locked into further impacts, and that these impacts will get much worse unless we act now to tackle the problem."
