Pence introduced Trump in the Rose Garden Thursday.
"President Obama made a bad deal, and President Trump can do better", Harris said. S. will withdraw from the Paris global climate pact.
Many in conservative circles outside the White House are still in wait-and-see mode.
The speech was a "calculated gamble", Richard Gowan, research director at NYU's Center on International Cooperation, said, adding that Trump may "react badly" to even a limited challenge from the United Nations, which he views with suspicion.
Abandoning the pact was one of Trump's principal campaign pledges.
Some of Trump's aides have been searching for a middle ground - perhaps by renegotiating the terms of the agreement - in an effort to thread the needle between his base of supporters who oppose the deal and those warning that a USA exit would deal a blow to the fight against global warming as well as to worldwide US leadership. The Paris deal "really put an extraordinary burden on the American economy while allowing some countries around the world like China and India to literally go a decade or more without any accountability for reducing C02 emissions", Pence said.
Claiming that the Paris climate accord was not tough on India and China, President Donald Trump declared Thursday that he was pulling the U.S. from the landmark agreement.
First, Guterres said he will immediately press for ratification of the Kigali Amendment agreed to in October by almost 200 nations on limiting the use of hydrofluorocarbons (HFCs) - greenhouse gases far more powerful than carbon dioxide that are depleting the ozone layer.
Germany's environment minister told reporters Friday "there will be no new deal with the United States" on climate change and predicted global climate will "survive" Trump's maximum presidential term of eight years. He then tweeted that he would make an announcement this week.
"The EU and China consider climate action and the clean energy transition an imperative", they will say, according to a draft of a statement from the leaders specifically on climate change and clean energy cooperation and seen by POLITICO. But he added that its implementation will not be as effective "without the key signatories".
"So we must do our utmost to increase ambition and action until we can bend the emissions curve and slow down global warming", he said.
In his opinion, business will benefit because it's much cheaper to deal with climate change on a global basis.
Speaking in Berlin about the Paris climate change accord, he said that "China in recent years has stayed true to its commitment". The Sierra Club said a United States withdrawal from the Paris deal would be a "historic mistake".
He added: "Fighting climate change is a global consensus, it's not invented by China. and we realize that this is a global consensus agreement and that as a big developing nation we should shoulder our worldwide responsibility".
With Trump this week giving hints that he might choose to have the United States withdraw from the Paris climate change accord ratified by 147 countries, Guterres said in a speech Tuesday that he believes climate change can't be denied, and added: "It is absolutely essential that the world implements the Paris Agreement".
Trump alleged that the Paris agreement on climate change agreed upon by more than 190 countries was "negotiated poorly by Obama admin and signed out of desperation". That promise helped rally supporters sharing his scepticism of global efforts to police USA carbon emissions.
The U.S.is the world's second-largest emitter of carbon, following only China.
Although Trump could get out of the non-binding deal's commitments by simply rolling back US climate policy, Juncker was adamant that it's not as easy to leave the treaty as Trump might think: "The climate deal says: It takes three, four years after the treaty took effect last November to exit the agreement".
Trump promoted his announcement Wednesday night on Twitter, after a day in which USA allies around the world sounded alarms about the likely consequences of a US withdrawal. Trump himself kept everyone in suspense, saying he was still listening to "a lot of people both ways".
"The White House's reckless decision to withdraw from the Paris Accord has devastating repercussions not only for the United States, but for our planet", Governor Cuomo said in a press release.
