Last week, temperatures in the UK reached a record-breaking 40.3 degrees centigrade. As Britons sweltered in their homes and offices, railway lines buckled, fires broke out in Greater London and the tarmac on Luton Airport runway began to lift. Climate Change scientists now describe this kind of heat as 'the new normal'.

How well is Britain set up to cope with extreme weather events? Do we need to start heat-proofing our houses and infrastructure? And does government need to focus more on adapting to climate change?
