The New York Times reports: A coalition of American states, cities and businesses that have pledged to stick with the Paris climate pact will team up with experts to quantify their climate commitments and share their plans with the United Nations, vowing to act in spite of the Trump administration’s exit from the accord.

President Trump said last month that the United States would withdraw from the Paris deal, isolating the United States on the world stage. At a Group of 20 summit meeting last week, world leaders agreed to move forward collectively on climate change without the United States, declaring the landmark 2015 pact “irreversible.”

But the coalition, called America’s Pledge — which now includes 227 cities and counties, nine states and about 1,650 businesses and investors — is moving to uphold the United States’ commitments under the Paris deal. The country had committed to reducing its greenhouse gas emissions by 26 to 28 percent by 2025, compared with 2005 levels.

The group, led by Gov. Jerry Brown of California and Michael R.
