World has six months to avert climate crisis, says energy expert

International Energy Agency chief warns of need to prevent post-lockdown surge in emissions

The world has only six months in which to change the course of the climate crisis and prevent a post-lockdown rebound in greenhouse gas emissions that would overwhelm efforts to stave off climate catastrophe, one of the world's foremost energy experts has warned.

This year is the last time we have, if we are not to see a carbon rebound," said Fatih Birol, executive director of the International Energy Agency.
