Pandemic shows climate has never been treated as crisis, say scientists

Letter also signed by Greta Thunberg urges EU leaders to act immediately on global heating

Greta Thunberg and some of the world's leading climate scientists have written to EU leaders demanding they act immediately to avoid the worst impacts of the unfolding climate and ecological emergency.

The letter, which is being sent before a European council meeting starting on Friday, says the Covid-19 pandemic has shown that most leaders are able to act swiftly and decisively, but the same urgency had been missing in politicians' response to the climate crisis.
