Trump Revokes Key Climate Ruling, Calls it 'Largest Deregulation in American History'

• US President Donald Trump overturned a 2009 'endangerment finding' that declared greenhouse gases a public health threat.
• The finding, introduced during Barack Obama’s presidency, served as the legal basis for federal climate regulations.
• The White House described the reversal as the 'largest deregulation in American history,' claiming it would reduce costs for car manufacturers and lower vehicle prices.
• Trump criticized the earlier policy as 'disastrous' and a 'radical rule' that damaged the American auto industry.
• Environmental groups are preparing court challenges, while former President Obama criticized the rollback, stating it would leave Americans less safe and healthy.
