McCarthy said she isn't anxious about the long-term prospects for moving ahead on clean energy and reducing carbon emissions to counter the effects of global warming and climate change.
The White House did not immediately respond to an email seeking comment on the lawsuit.
However, it still remains unclear whether Trump will be able to do so as environmentalists believe most of these moves will certainly end in court.
"What's been going on is a switch to more natural gas and away from coal", Kelly said.
"Poll after poll shows that the public supports climate action".
French election debate: three hours on air, but no clear victor
After generations in which France has been dominated by the Socialists and conservatives, neither party seems capable of winning. Macron would finish first and second in the first round of balloting on April 23 and advance to a second-round faceoff on May 7.
Lu recalled that it had not been easy to arrive at the 2016 Paris Agreement, which Trump has threatened to abandon, and hailed the pact as "a milestone in the global campaign in climate governance".
However, Karsten Haustein at the University of Oxford believes while lifting the regulations may slow down the pace, it will not stop the fight to reverse global warming.
"As long as natural gas is cheaper than coal to produce electricity, it will capture larger and larger shares of the market, and that will drive Carbon dioxide emissions down", Ringel said. Trump wants to repeal it as a step towards boosting the struggling coal industry.
McCarthy's comments come after the president moved Tuesday to roll back the so-called Clean Power Plan, which seeks to reduce the country's greenhouse gas levels by almost 30 percent over the next 10 years.
The president has also said he does not intend to honour promises made by the administration of his predecessor, Barack Obama, to give billions of dollars in aid to poor, climate-vulnerable nations. As the world's second-largest emitter of greenhouse gases - behind China - and by far the biggest historically much of the world looks to the United States when deciding how much money they are prepared to spend to fight global warming.
"The president doesn't get to simply rewrite safeguards; they have to. prove the changes are in line with the law and science", said the NRDC's Goldston. He continued saying "They haven't been treated well, but they're going to be treated well now". "They are not coming back".
