President Donald Trump's decision to pull the USA out of the Paris Agreement on climate change and the strongly negative reaction by some groups regarding that decision are focused mainly on trade-offs and questions about the data used in evaluating those trade-offs.
Robert Orr, one of the architects of the Paris accord and a former special advisor to the UN secretary general on climate change, told AFP that the United States had already been on track to achieve about half its Paris reductions commitment.
The Cambridge, Massachusetts-based research university published a study in April 2016 titled 'How much of a difference will the Paris Agreement make?' showing that if countries abided by their pledges in the deal, global warming would slow by between 0.6 degree and 1.1 degrees Celsius by 2100.
Americans value jobs, want an expanding and exuberant US economy, and certainly where possible would like to restrict unnecessary federal government expenditures.
A joint statement from Germany Chancellor Angela Merkel, Italian Prime Minister Paolo Gentiloni and new French President Emmanuel Macron expressed no appetite for renegotiating the accord, calling it a "vital instrument" and "irreversible".
With Trump seeking to renegotiate the climate accord, the prospects of which remain highly unclear, US sub-national bodies have committed to sticking to the parameters of the Paris agreement.
Under the pact, the United States - the world's second biggest carbon emitter behind China - had committed to reduce its emissions by 26 percent to 28 percent from 2005 levels by 2025.
U.N. Secretary-General Antonio Guterres called the US withdrawal from the Paris climate agreement "a major disappointment" and said it was "crucial that the United States remains a leader on environmental issues", according to his spokesman.
If President Trump thinks that the decisions of the Paris climate conference need changes he should discuss in the world forum and seek corrective measures instead of running away.
Trump said the agreement disadvantaged the U.S.
He said he would notify the U.N. Secretary General and the climate change secretariat that USA cities, states, businesses and others will aim to meet the United States' commitment to reducing emissions 26 percent below the 2005 levels by 2025.More news: Andretti backs Alonso for Indy 500 glory

Trump said participation in the pact would undermine the USA economy, wipe out American jobs, weaken national sovereignty and put America at a disadvantage to other countries. The statement said Trump thanked the four leaders for having "frank, substantive" discussions on the issue and reassured them that the USA remains committed to robust efforts to protect the environment.
If Trump had stayed in, he could have used the tools in the agreement - meant to ratchet up commitments to cut emissions - as a way to cut the USA targets.
"I think there's a change in weather".
Corporate leaders also see green energy as an aspect of many developing industries and possible marketing tool.
"Who created the League of the Nations?" It was the United States who set up the League of the Nations.
"So if a locality, a municipality, or state wants to enact a policy that their voters or their citizens believe then that's what they should do", White House spokesman Sean Spicer said. "Trump's move doesn't change that".
This brings us back to politics. But leaders from around the world have already hailed the agreement as a breakthrough for the fight against climate change, a victory for worldwide co-operation, and a boon to the global economy.
But Trump's decision undermines every one of these goals, and it goes against the wishes of a vast majority of Americans, including many of his own supporters. "Climate change is real, and we all share a responsibility to fight it".
The United Nations said America's exit from Paris was a "major disappointment", with a spokesman for Secretary- General Antonio Guterres urging the USA to remain a "leader on environmental issues". The automaker highlighted its development of the Chevrolet Bolt electric vehicle with 238 miles of range on a single charge and a net price of less than $30,000. In recent years, in fact, it has worked to reduce greenhouse gas emissions.
It's worth noting that the United States did not ratify the agreement - it was never passed by Congress - so much of the hand-wringing over Trump's decision is largely much ado about nothing.
