If global warming would save lives in the UK, should we spend enormous amounts of money in futile attempts to stop it?

The biggest possible benefit for the UK appears to be reduced winter mortality - Defra predicts there could be between 5,000 and 24,000 fewer premature deaths from the cold. 

But on balance, it's doubtful the benefits of climate change will outweigh the risks in the UK - even below two degrees of warming, according to Defra's report. While we may be experiencing better wheat yields in the 2080s, it looks like there will be plenty to worry about: Defra says possible impacts will water shortages, and an extra 1,000 to 6,000 summer deaths.
