Trump signs order to withdraw U.S. from Paris climate agreement

President Donald Trump has signed an executive order to withdraw the United States from the Paris climate agreement. This decision marks a significant shift in U.S. climate policy, as the country joins Libya, Yemen, and Iran in not participating. The Paris Agreement aimed to limit global temperature rise and included commitments from nations to reduce greenhouse gas emissions. The U.S. withdrawal will be effective immediately upon notification to the United Nations. Trump's administration plans to reverse various climate initiatives from the previous administration, including emissions limits and offshore drilling bans. He has also declared a "national energy emergency" to promote U.S. energy production.
