"The Paris agreement is a symbol of the Obama administration's "Washington knows best" approach to governing".That promise helped rally supporters sharing his scepticism of global efforts to police US carbon emissions."Withdrawal from the climate change agreement would be a job killer", Blumenthal said.Mr Musk, who has been in Sydney this week with his family, said on Twitter he had done all he could to advise Mr Trump to keep the United States in the deal.Trump's advisers have been split about the Paris accord.
A US withdrawal could deepen a rift with USA allies.
"The Paris agreement establishes the enduring framework the world needs to solve the climate crisis", Obama said, speaking from the White House. Trump himself kept everyone in suspense, saying he was still listening to "a lot of people both ways".
Scientists say Earth is likely to reach more risky levels of warming sooner if the US retreats from its pledge because America contributes so much to rising temperatures.
Christiana Figueres, who oversaw six years of United Nations climate negotiations that produced the Paris deal, told Bloomberg BNA she is optimistic Trump's actions won't dampen the broader signal sent by the almost 200 nations that reached the 2015 agreement-that the world should move toward a low-carbon future.
It could have sweeping implications for the deal, which relies heavily on the commitment of big polluter nations to reduce emissions of gases that scientists blame for sea level rise, droughts and more frequent violent storms.
Under Obama, Washington had pledged to reduce greenhouse gas emissions by 26-28 percent below 2005 levels by 2025.
Advocates of the climate deal pressured Trump, who has changed his mind on large decisions before even after signaling a move in the opposite direction.
President Donald Trump speaks to USA military troops and their families at Naval Air Station Sigonella, Saturday, May 27, 2017, in Sigonella, Italy. The president has pledged to reverse decades of decline in coal mining, which now accounts for fewer than 75,000 U.S.jobs.
The U.S. and China are the two biggest emitters of carbon in the world, and if the U.S. were to leave the agreement, it could significantly jeopardize the pact's potential to succeed, according to Climate Central.
The pact became one of President Barack Obama's signature achievements.
The implications of a USA withdrawal, though, are profound and far-reaching.
Trump's influential daughter Ivanka Trump's preference is to stay, but she has made it a priority to establish a review process so her father would hear from all sides, said a senior administration official.
Obama and a host of other countries signed the climate change agreement in 2015 and the former president touted it as the "best chance we have" to save the planet.
"Don't know which way Paris will go, but I've done all I can to advise directly to POTUS, through others in WH & via councils, that we remain", Musk said on Twitter.
Democratic U.S. Senators Bob Menendez and Jack Reed wrote a letter urging Trump not to withdraw. A January 2016 analysis by the consulting firm Rhodium Group said under the rosiest of scenarios-and assuming the Obama rules were left untouched-the US could make a 23 percent emissions cut by 2025.
China and the European Union will seek on Friday to buttress the agreement. And it could trigger further efforts to erode the landmark climate accord. They said the deal would require the United States of America government to regulate greenhouse gas emissions, which would hurt business.The accord aims to limit planetary warming in part by slashing carbon dioxide and other emissions from burning of fossil fuels.
