"In order to fulfil my solemn duty to protect America and its citizens, the United States will withdraw from the Paris Climate Accord, but begin negotiations to re-enter either the Paris Accord or a really entirely new transaction on terms that are fair to the United States, its businesses, its workers, its people, its taxpayers". Elsewhere, the decision was widely condemned by business leaders. "Today's decision therefore greatly increases the chances that the global effort to reduce carbon emissions will be insufficient to avert catastrophic consequences for human health".
For anxious allies, Trump's rejection of the Paris pact is particularly jarring in the wake of his first worldwide trip last week. "Celsius reduction in global temperature by the year 2100", he said, adding: "Tiny, tiny amount".
In the hard-fought pact's own wording, a party may withdraw by giving written notification "any time after three years" of its entry into force - which was on November 4, 2016.
Past year was the warmest since records began in the 19th century.
Coal-fired power plants are a major source of Carbon dioxide emissions. Suddenly, a global peaking of emissions by 2020 looks possible. Since the Paris Agreement entered force on November 4, 2016-mere days before Trump's election-the earliest date that the US could even give such legal notice would be November 4, 2019. However, it's essential that those efforts combine with systemic changes across the globe - and the Paris agreement is an wonderful opportunity to make those changes happen.
U.S. states and cities can also act without federal leadership.
So while this decision is an egregious self-inflicted wound, as Yogi Berra liked to say, it ain't over till it's over.More news: Death toll from London terrorist attacks rises to seven

That would hit the USA auto industry hard, and bring "the further decimation of vital American industries on which countless communities rely", the president said, returning to the populist rhetoric he rode all the way to Oval Office: "They rely for so much, and we would be giving them so little".
A group of 82 mayors, including the mayors of New York City, Los Angeles and Chicago, said in joint statement they "will adopt, honor, and uphold the commitments to the goals enshrined in the Paris Agreement". But it seems unlikely that this issue has the power to shift votes from one side to another. Those comments from industry leaders in favor of remaining in the Paris climate pact with different emissions standards for the United States were interpreted inside the administration as the CEOs actually opposing the Obama administration-negotiated levels, the official said.
In pulling out of the Paris climate accord, Mr. Trump has created a vacuum of global leadership that presents ripe opportunities to allies and adversaries alike to reorder the world's power structure.
And separate from Thursday's announcement, he had already decided on steps that could undermine worldwide action. Through the We Mean Business Coalition, 471 companies with over $8 trillion in market capitalization have undertaken more than 1000 climate action commitments. "There is no backsliding on the Paris Agreement".
In television interviews the morning after Trump's announcement, Vice-President Mike Pence and Kellyanne Conway, a senior White House aide, defended Trump's decision as a reassertion of America's sovereignty. Remember that global emissions need to hit zero by 2070.
The study makes worst-case assumptions that may inflate the cost of meeting USA targets under the Paris accord while largely ignoring the economic benefits to US businesses from building and operating renewable energy projects.
