As darkness set in over the Peak District one Wednesday night in June, calls started to come in to Derbyshire's fire service over smoke starting to rise from the moorland overlooking the town. More than a month on, the Tintwistle Moor fire is now a sprawling, smouldering blaze the size of a small town, which can be seen from space. Declared a major incident on 12 July, it has come in tandem with a prolonged spell of hot, dry weather that shows little sign of easing soon, pushing the country's firefighting resources to their limits. Now Dr Kirsten Lees, environmental sciences lecturer, specialising in zero carbon at the University of Derby, has told the BBC Tintwistle is on a par with the biggest wildfires ever seen in England - and it's still burning. When questioned about her assertion the fire could be one of the largest in recent memory in England, she said: "It may well be, yes."
