Dale Marshall of Environmental Defence issued a statement calling Thursday "a bleak day" for climate change and global diplomacy, but also expressing confidence the accord would survive the USA pullout.
As President Donald Trump explained his rationale for withdrawing from the Paris climate agreement on Thursday, he cited research that seemed to suggest the global emissions cuts agreed to under the deal wouldn't make a significant difference in worldwide temperatures. Previous year at a United Nations climate meeting, Paul Oquist, head of the Nicaraguan delegation, once again explained why the Central American country wouldn't participate in the accord.
Trump took a very different view of the 2015 agreement, stating that it was "another example of Washington entering an agreement that disadvantages the USA", according to the Independent.
The U.S. under the Obama administration played a leading role in making the deal come together and convincing China and other developing countries that they needed to join the fight against global warming.More news: Christians Killed in ISIS Attack in Egypt

US allies around the world have expressed concern about what will happen if America pulls out of the agreement.
Meanwhile, the mayor of Pittsburgh also fired back after Trump said, "I was elected to represent the citizens of Pittsburgh, not Paris".
Trudeau vowed to continue working with USA states that support climate action "to drive progress on one of the greatest challenges we face as a world".
The only other nations not participating in the accord are Syria and Nicaragua.
Trump said the USA will negotiate re-entering the accord or "an entirely new transaction", calling the Paris Accord unfair to the U.S.
Trump announced during a speech at the White House Rose Garden that he had made a decision to pull out of the landmark climate deal, in part because it would not reduce global temperatures fast enough to have a significant impact.
Weather.com's editor Sean Breslin weighed in on Twitter on Thursday afternoon to clarify that its messaging wasn't meant to troll Trump's decision, but rather to educate. "And if we can't, that's fine", he said.
