‘Grownup’ leaders are pushing us towards catastrophe, says former US climate chief

Paris agreement negotiator Todd Stern attacks premiers who say that decarbonisation programmes are unrealistic and should be slowed down

Political leaders who present themselves as “grownups” while slowing the pace of climate action are pushing the world towards deeper catastrophe, a former US environment chief has warned.

“We are slowed down by those who think of themselves as grownups and believe decarbonisation at the speed the climate community calls for is unrealistic,” said Todd Stern, who served as a special envoy for climate change under Barack Obama, and helped negotiate the 2015 Paris agreement.
