Are over-insulated homes causing more heatwave deaths?

As we know, carbon emissions are going to have to be eliminated in the coming decades to prevent us suffering from fire, flood, tempest and plagues of locusts. But in one important respect is the cure actually worse than the disease? That’s the surprising implication of a statement on deaths from last year’s heatwave by Bob Ward, the Director of the Grantham Research Institute on Climate Change at the London School of Economics. In response to figures suggesting that there were 892 excess deaths between last June and August, a period which saw the highest temperature ever recorded in Britain, he said: ‘Tragically, many of these deaths are likely to have been preventable. Previous research has shown that many of the people who are killed by heatwave conditions die in their own homes or in care homes that overheat.’
