President Trump heard the pleas again and again this week: Do not abandon the Paris climate accord.

The president of France tried to persuade him. So did the prime minister of Belgium and the heads of the European Union. Then there was Pope Francis, who gifted Trump a copy of his encyclical on preserving the environment and the “care of our common home.”

The lobbying campaign intensified at the Group of Seven summit that opened Friday here in Sicily as the leaders of America’s closest allies each gave Trump an earful about keeping America in the 2015 Paris agreement reached under President Barack Obama.

They are hopeful they can persuade a man who labeled climate change “a hoax” and vowed to disentangle the United States from global agreements on the campaign trail that the world’s security and economic future depends on addressing global warming.
