'Believe your own damn eyes', Newsom responds to Trump withdrawing from Paris climate agreement

On day one in office, President Trump signed an executive order directing the United States to again withdraw from the Paris climate agreement.

The main goal of the Paris Agreement is to keep long-term global temperatures from warming 1.5 degrees Celsius (2.7 degrees Fahrenheit) above pre-industrial times and if not that, well below 2 degrees Celsius (3.6 degrees) by slashing planet-warming emissions from coal, oil and gas.

During his first term in office, Trump pulled the U.S. from the global Paris accord, but then-president Biden reversed the order and had the US rejoin on his second day in office. 

Following the withdrawal, California Gov. Gavin Newsom released a statement slamming Trump for his actions. 

"If you don’t believe in science, believe your own damn eyes," Newsom said in a statement

Once the withdrawal takes effect next year, the United States joins Iran, Libya and Yemen as the only United Nations countries that are not part of the agreement.

The U.S. withdrawal, while expected, triggered heavy reactions from around the world, dealing a blow to worldwide efforts to combat global warming and once again distancing the U.S. from its closest allies.
