TLDRThe US has officially exited the Paris climate agreement for the second time, cementing Donald Trump’s break with the primary global venue to address global heating. This move leaves the US as the only country to have withdrawn from the pact, complicating global climate efforts. Investment in low-carbon energy is outpacing fossil fuels, with China leading the green transition. Trump’s policies risk pushing the US to the margins of the global climate effort, potentially slowing momentum elsewhere.
