Climate change action 'unstoppable' despite Trump: U.N.'s Ban

At a meeting of almost 200 nations in Morocco to work out ways to implement the 2015 Paris agreement to limit greenhouse gas emissions, Ban said U.S. companies, states and cities were all pushing to limit global warming.

"What was once unthinkable has become unstoppable," he told a news conference of the Paris Agreement, agreed by governments last year, and which formally entered into force on Nov. 4 after a record quick ratification.

Ban said Trump, as a "very successful business person", would understand that market forces were already driving the world economy towards cleaner energies such as wind and solar power, as they become cheaper and away from fossil fuels.

The Paris accord, aiming to phase out net greenhouse gas emissions this century, was a breakthrough after more than two decades of deadlock, driven by increased scientific certainty that man-made emissions drive heat waves, floods and rising sea levels.

Ban said he hoped that Republican Trump, elected last Tuesday, would drop his view that man-made climate change is a hoax and his pledge to cancel the Paris Agreement.

"I am sure he will make a ... wise decision," Ban said, saying that climate change was having severe impacts from the Arctic to Antarctica. He noted this year is on track to be the warmest year since records began in the 19th century.

"I hope he will really hear and understand the seriousness and urgency of addressing climate change. As President of the United States I hope he understands this, listens and evaluates his campaign remarks," he said.

Ban said that companies including General Mills and Kellogg, states such as California and cities such as Nashville and Las Vegas were working to cut their greenhouse gas emissions.

Ban, who will step down at the end of the year after a decade in charge of the United Nations, has made action on climate change a core issue of his time in office.

Trump's victory has overshadowed the Nov. 7-18 Marrakesh meeting, which had opened with congratulations after the entry into force of the agreement on Nov. 4. It now has formal backing from 110 nations including the United States.

Trump has said he will boost the U.S. coal, oil and shale industries, abandoning President Barack Obama's plan to cut greenhouse gas emissions by 26-28 percent below 2005 levels by 2025.

His victory has lifted shares in coal producers, while knocking renewable energies.
