Yes, this is England’s hottest July day ever. But this tells us nothing about global warming
From our UK edition
If you were deliberately trying to obtain a record high temperature reading an international airport would be a good place to take your thermometer. With huge concrete aprons and planes spewing out large quantities of hot air, airports have a microclimate of their own. That is one reason not to get excited by today's record July temperature of 98 degrees Fahrenheit (36.7 Celsius) measured at Heathrow. But there is another very good reason why the familiar clattering of broken weather records does little to reinforce the narrative of climate change. There are four countries in the UK, 12 months of the year and 4 main records to beat: hottest, coldest, wettest and driest.
