The Prince of Wales has warned that the world is in a “critical decade” to try and set the planet on a “healthier” path to deal with the climate crisis. William spoke in central London as he joined supporters of the Earthshot Prize Launchpad, a new platform aimed at helping develop and make potential climate change solutions a reality. He told guests, including former New Zealand prime minister Jacinda Ardern who is an Earthshot Prize trustee: "From businesses, cities and governments; to activists, scientists and innovators, the ideas and ambition to set our planet on a healthier path do already exist. But this is urgent”.
