The Paris Climate Agreement, adopted in 2015, sought to limit global temperature increases to 1.5 degrees Celsius above pre-industrial levels by encouraging countries to voluntarily set targets to reduce greenhouse gas emissions. This marks the second time the United States has withdrawn from the Paris Agreement. Secretary of State Marco Rubio has closed the State Department’s climate office and dismissed staff involved in international climate negotiations. The Trump administration is additionally pursuing an exit from the U.N. Framework Convention on Climate Change, signaling a broader retreat from international climate policy cooperation.
