China declared it was stopping all dialogue with the US on major issues, including climate, as it looks to retaliate for the diplomatic sleight of House Speaker Nancy Pelosi’s visit to Taiwan. The move threatens to derail cooperation between the world’s two largest climate polluters, collectively responsible for about 40% of the world’s climate pollution. “[Y]ou can freeze talks, [but] you cannot freeze climate impacts,” Laurence Tubiana, chief executive of the European Climate Foundation and architect of the Paris climate agreement told the Guardian. While the US is now poised to pass the most significant climate legislation ever, China’s leader Xi Jinping has pledged to achieve carbon neutrality by 2060.
