The news came as President Donald Trump yesterday unveiled a new executive order that could roll back some of the previous Democratic administration's policies aimed at curbing greenhouse gas emissions and climate change.
It will "allow our companies and our workers to thrive, compete, and succeed on a level playing field for the first time in a long time", he said.
"China wants to take over the role of the U.S.as a climate leader, and they've baked it into their five-year (economic) plans", she added.
Trump's executive order rescinds more than half a dozen federal regulations and guidance that aid in making the USA food system more climate resilient. He said his executive order would bring back jobs.
The move was widely expected after Trump released his budget proposal two weeks ago, which slashed funding for the EPA by 31 percent. People across Wyoming stood up to fight this bad rule from the Obama Administration, and they did it because they care about their friends, neighbors and communities that rely on the coal industry.
The Trump administration has not said whether it will pull out of the Paris deal.
The office's climate projections show Philly is likely to experience a drastic increase in heat waves, heavy precipitation events and flooding throughout the next century.
Christy Goldfuss, an energy expert at the Center for American Progress, said that whatever policy changes Trump makes, it is the markets that will decide what industry is viable.
But in 2007 Exxon admitted publicly that climate change poses risks and said it's responsible to begin working on ways to reduce emissions.
Even though Trump is a climate change skeptic, his secretary of state and leading emissary on climate issues, does not appear to be one.
The order, if fully implemented, would make US compliance impossible with the global Paris Agreement to limit climate change.
That includes the Clean Power Plan, which restricts greenhouse gas emissions at coal-fired power plants.
Trump has threatened to pull the USA out of the Paris Agreement during his presidential campaign, but the order did not address this issue.
Mr Trump's order also asks federal agencies to discount the cost of carbon in policy decisions and the weight of climate change considerations in infrastructure permitting, and it reverses rules limiting methane leakage from oil and gas facilities. The Obama administration's punishing regulations have done far more harm to our economy than good for the environment.
Trump's Environmental Protection Agency chief, Scott Pruitt, alarmed environmental groups and scientists earlier this month when he said he does not believe carbon dioxide is a primary contributor to global warming.
The Obama administration, some Democratic-led states and environmental groups counter that it would spur thousands of clean-energy jobs and help the USA meet ambitious goals to reduce carbon pollution set by the global agreement signed in Paris.
