A US president who recognises the threat will make a huge difference, but environmentalists must push hard
There is no question that Joe Biden’s win will make a big difference to international efforts to deal with the climate emergency. A US president who recognises global heating as an “existential threat” will be a vital extra pillar propping up the teetering edifice of climate diplomacy. Four years of Donald Trump have done huge damage to the US’s reputation. But the world’s biggest economy, and second-biggest emitter of greenhouse gases (after China), remains vastly influential. With President Biden in charge, the prospects for next year’s Cop26 talks in Scotland, when drastic emissions cuts must be agreed if the world is to stand a chance of avoiding catastrophic heating, are already brighter.
President Trump’s withdrawal of the US from the Paris agreement was a key plank of his nationalist “America first” agenda and an act of sabotage against both the UN climate process and the principle of a rules-based international order. It also gave cover to the world’s other climate vandals: Saudi Arabia, Brazil, Russia and Australia. With Mr Biden, that cover is gone, and ecocidal policies such as Amazon rainforest destruction and coal-power expansion should come under renewed and relentless pressure. It is striking that the president-elect put climate at the heart of his phone calls with foreign leaders.
