A US appeals court issued a ruling Monday dismissing a case on a highway emissions reductions rule from former President Joe Biden after the new Department of Transportation (DOT) dropped its legal defense of the mandate.

Prof James Hansen says pace of global heating has been significantly underestimated though other scientists disagree

The pace of global heating has been significantly underestimated, according to renowned climate scientist Prof James Hansen, who said the international 2C target is “dead”.

A new analysis by Hansen and colleagues concludes that both the impact of recent cuts in sun-blocking shipping pollution, which has raised temperatures, and the sensitivity of the climate to increasing fossil fuels emissions are greater than thought.

Deprived of Rachel Reeves’s affections, the energy secretary revelled in playing climate crisis hero to her villain

He lives!

They seek him here! They seek him there! For the last ten days or so, Ed Miliband has been the Invisible Man.
