US President Donald Trump framed his sweeping rollback of federal climate change policy on Thursday as a political win over the Democratic Party's 'radical' environmental agenda, reprising a message Republicans have used in past elections and could turn to once again ahead of November's crucial midterms. His announcement at the White House was one of the most significant moves of his second term in office. The president stated he was revoking an Obama-era 'endangerment finding' from 2009 which claimed pollution harms public health and the environment. For almost 17 years, the US has used that scientific finding as the legal basis to establish policies to reduce emissions from cars, power plants, and other sources of planet-warming gases. 'This radical rule became the legal foundation for the Green New Scam,' Trump stated, underscoring the culmination of a decade-long effort to dismantle policies deemed necessary for combatting climate change. Alongside environmental advocates, many Democrats have expressed outrage, warning that the rollback could severely hinder the US's ability to address climate issues.
