Climate crisis: history will judge failure to act, Johnson says at UN

PM's warning to world's richest countries comes amid suggestions US could commit more funds

Boris Johnson has warned the world's rich countries that history will judge", if they fail to act now to tackle the climate crisis, as US climate envoy John Kerry suggested President Biden was poised to commit more funds to the fight.
