US move to pull out of Paris climate pact could add 0.3 degrees of warming: UN

Mains Paper 3: Environment | Conservation, environmental pollution and degradation, environmental impact assessment

Announcement of US pullout has left the whole world wondering about future of Paris climate deal. It is too early to speculate anything and we will wait for some op-eds to gain a holistic view of the issue.

From UPSC perspective following things are important:

Prelims level: Paris agreement, Role of various agencies in it and other related issues.

Mains level: Initial points to be noted are- support of few states of US to the climate deal and China and EU coming ahead as leaders. This also shows how the future of geopolitics will be shaped around climate
change as its effects become more visible with passing time.

• The US withdrawal from the Paris climate pact could “in a worst case scenario” add a 0.3 degree Celsius rise in global temperatures over the 21st century, the United Nations said on Friday

• US President Trump announced on Thursday that his administration would immediately stop implementing the “bad” 195-nation accord brokered by his predecessor Barack Obama in 2015 in tandem with Chinese leaders

Target under Paris pact:
• Under the Paris deal agreed in 2015, world nations vowed steps to keep the worldwide rise in temperatures “well below” two degrees Celsius (3.6 degrees Fahrenheit) from pre-industrial times
• The deal was structured to require action from multiple levels of government, including municipal, regional and federal authorities

Not all in support of Trump:
• With some US cities and states immediately voicing support for the Paris deal following Trump’s
announcement, it is unlikely that the country as a whole will see zero implementation of the pact in real terms

China and EU come ahead:
• China and the European Union have swiftly moved to fill the leadership void on the Paris climate pact left by the

US pullout
• Beijing vowed on June 2, 2017 to uphold the Paris climate accord after the United States withdrew from the pact, saying it was a “responsibility shouldered by China as a responsible major country”.
