Trump leaves Paris climate treaty again

Experts say US move will undermine global green efforts

US President Donald Trump announced on Monday that the United States will withdraw from the Paris Climate Agreement for a second time, a move experts warn will undermine global climate efforts, harm the US' international reputation, and result in lost economic opportunities for the country.

Trump signed an executive order late Monday to pull the US out of the Paris climate accords. The order stated, "It is the policy of my administration to put the interests of the United States and the American people first." The formal exit will occur in one year, as per the accord's rules.

This announcement, anticipated since Trump's election, significantly threatens the Paris Agreement's goal to limit global temperature rise to 1.5 degrees Celsius, especially since last year was the hottest on record.
