As was pointed out in another article Obama entered into the agreement (not treaty) without approval of Congress.

President Trump has every legal right to withdraw from it.

Paris Climate Agreement had Devastating Economic Costs for US While China’s Pollution Continues

By:  Joe Hoft

"....The fact that China does not have to cut any carbon dioxide emissions until 2030 is absurd.  What is also absurd is that the US would have to cut emissions and increase energy costs while giving money to other countries in a socialist scheme under the guise of ‘climate control’.

Last year I traveled from Hubei Province in China to Hunan Province in a five hour car ride on a new super highway in the middle of China.  The highway was new but the back roads were not so good.  The unforgettable aspect of this 300 mile journey was that the air and sky were severely polluted the entire five hours.  There was no blue sky and no clouds in the sky either. ...."

"....The fact that China is given a 13 year pass in the Paris Climate Agreement while the US was to sacrifice for years in money, jobs and increased energy costs is the main reason that getting out of the agreement was the best thing President Trump could do for the US.

MAGA"
