The world has already warmed by about 1.2C since mass industrialization, causing a 20% chance of having the sort of extreme summer temperatures currently seen in many parts of the northern hemisphere, up from a 1% chance 50 years ago, Hansen said.

“There’s a lot more in the pipeline, unless we reduce the greenhouse gas amounts,” Hansen, who is 82, told the Guardian. “These superstorms are a taste of the storms of my grandchildren. We are headed wittingly into the new reality – we knew it was coming.”

Hansen was a Nasa climate scientist when he warned lawmakers of growing global heating and has since taken part in protests alongside activists to decry the lack of action to reduce planet-heating emissions in the decades since.
