He ran a study which concluded it was “virtually impossible” to have reached those temperatures without humanity’s greenhouse gas emissions.

“This couldn’t happen without climate change … it’s the first time that any study has been able to make such strong conclusions,” he says. That study landed on the front page of the New York Times, which described it as “perhaps the most definitive statement climate scientists have made tying a specific weather event to global warming”.
