Benedict Cumberbatch is dreading stepping outside. He’s speaking to me from his air-conditioned hotel room in Soho at the peak of the summer heat. Few doubt that climate breakdown was a major cause of those scorchers, with nature, farming and water supplies all placed under huge strain. By midsummer, according to a report co-authored by the Met Office, there were 2,700 excess deaths in England and Wales due to the searing heat.
But for Cumberbatch, in a bittersweet way, the record-breaking temperatures have come at a good time. The actor has been on a tour to promote his new documentary, How to Live on Earth. “The irony is not lost on anyone,” he says. “We’re living in the results of climate breakdown so stepping outside is – literally – a call to action.”
