BERLIN — The United States on Wednesday formally left the Paris Agreement, a global pact forged five years ago to avert the threat of catastrophic climate change.
The move, long threatened by President Donald Trump and triggered by his administration a year ago, further isolates the U.S in the world but has no immediate impact on international efforts to curb global warming.
Some 189 countries remain committed to the 2015 Paris accord, which aims to keep the increase in average temperatures worldwide “well below” 2 degrees Celsius (3.6 degrees Fahrenheit), ideally no more than 1.5C (2.7 F), compared to pre-industrial levels. A further six countries have signed, but not ratified the pact.
Scientists say that any rise beyond 2 degrees Celsius could have a devastating impact on large parts of the world, raising sea levels, stoking tropical storms and worsening droughts and floods.
