"If the United States pulls out of Paris, it sets in motion potentially an acceleration of the original Paris prognosis we had, which is that this probably ends with trade-based measures", particularly because the agreement didn't include enforcement provisions, Book said before the president's announcement. He also misrepresented China's commitment to the pact, and generally sought to paint the accords as a devious plot by 194 nations to take America's money.
By bailing on the Paris deal, the US federal government "is on its own", said Höhne, a founding partner of the NewClimate Institute. But he indicated that was hardly a priority. After all, the Silicon Valley has been anything but friendly to Trump, and their ideals greatly differ from those of the United States president. "If we can't, that's fine", he said.
Scientists say Earth is likely to reach more unsafe levels of warming sooner as a result of the president's decision because America's pollution contributes so much to rising temperatures.
Trump also failed to acknowledge that India's per capita carbon emissions are a mere fraction of the US's, or almost 300 million people in India still live without reliable access to electricity, while misstating that India's participation in the accords was contingent on receiving "billions and billions and billions" of dollars in aid.
The leadership Pence seemed to be most impressed with, however, was Trump's.
The White House indicated it would follow the lengthy exit process outlined in the deal. "The U.S. withdrawal definitely does not mean that reaching the $100 billion goal is impossible".
Trump's move could still give some countries the political cover to scale back their efforts to reduce greenhouse-gas emissions, says Niklas Höhne, a founding partner at the NewClimate Institute in Cologne, Germany.
Under former President Barack Obama, the US had agreed under the accord to reduce polluting emissions by more than a quarter below 2005 levels by 2025.
The decision left the U.S.as the only major country that won't be part of the 195-country global accord - and just one of three worldwide.
Hours later German Chancellor Angela Merkel summoned reporters for an impromptu statement in which she called Trump's decision "extremely regrettable, and that's putting it very mildly".
Former Mexican President Vicente Fox, who has been a vocal critic of Mr. Trump's plan to build a wall along the Mexico-U.S. border, chimed in on the climate decision, too.
The U.S. Chamber of Commerce points to a study by NERA Economic Consulting, which cites a $3 trillion hit to America's GDP and the loss of 6.5 million industrial jobs by 2040 if the U.S. were to make good on its promises under the Paris accord. "We are continuing work toward achieving the goals of European Union climate policy and will follow the aims of the Paris Agreement", he affirmed.
But Mr. Trump's withdrawal from the Paris pact wasn't entirely without support. Many economists believe the accord would likely help create about as many jobs in renewable energy as it might cost in polluting industries. But much of the financing and technology sharing that flows between the U.S. and India isn't part of the Paris accords, but is laid out in bilateral agreements between the two countries.
The immediate impact of Trump's move could be largely symbolic. The White House said the US will stop contributing to the United Nations Green Climate Fund and will stop reporting carbon data as required by the Paris accord, although domestic regulations require that reporting anyway. If successful, Trump's rollbacks could cause the U.S.to release 0.4 gigatons more carbon dioxide in annual emissions in the year 2030 than if those policies remained, the report says.
It's not unlike Trump to go against what people are advising him to do, but there's something highly symbolic in the USA president shunning the leaders of Earth's largest innovation center. Just ask Republican Congressman Tim Walberg of MI.
Secretary of State Rex Tillerson, who had urged Trump to stay in the Paris deal, did not attend the ceremony, nor did Trump's son-in-law Jared Kushner and his wife, Ivanka, both close advisers to the president who supported staying in the agreement. Along with the U.S., India and China are among the world's greatest polluters.
That claim was attributed to research conducted by MIT, according to White House documents seen by Reuters. But Trump's statement was clear and direct.
