介绍:
America formally left the Paris climate agreement, (which is) something that Mr Trump first promised to do in 2017. Of the nearly 200 nations that signed the agreement = signatory = participating countries, the U.S. is the only one to walk away from its promises to reduce greenhouse gas emissions. The president claims that the pact, under which America promised to cut emissions by at least 26% from their 2005 levels by 2025, will hurt the economy. When the Paris Agreement was concluded in 2015, it was hailed as a historic commitment, among nearly 200 nations, to reduce greenhouse gas emissions to stave off the worst effects of climate change. The pact’s stated aim was to keep global average temperatures from increasing by more than two degrees Celsius above preindustrial levels by the end of this century and to pursue efforts to keep that temperature rise below 1.5 degrees C.
