John Kerry: UK climate summit is world’s last best chance

US climate envoy John Kerry has said a UN climate summit in the UK this November is ’’the last best chance’’ to avert the worst environmental consequences for the world.

He said years were lost on the climate issue under President Donald Trump, “who didn’t believe in any of it”.

Dozens of world leaders will attend the COP26 conference in Glasgow, Scotland.

Mr Kerry spoke as President Joe Biden signed a flurry of executive orders designed to address climate change.

His latest edicts include a freeze on new oil and gas leases on public lands and set out to double offshore wind-produced energy by 2030.

Mr Biden, who re-entered the US into the 2016 Paris climate accord in one of his first acts as president, said America must lead the response to the crisis.
