One empty chair at G-7 climate meeting: Trump's

BIARRITZ, France — U.S. President Donald Trump skipped a discussion on climate with other world leaders at the Group of Seven summit in France — then claimed to "know more about the environment than anyone."

Trump left an empty chair as global power brokers debated Monday how to help the fire-stricken Amazon and reduce carbon emissions.

"I'm an environmentalist," Trump told reporters, even as he celebrated America's oil and gas wealth.

Environmental activists declared the summit a failure, marching to demand tougher global emissions rules and more aid for the Amazon.

Trump was scheduled to attend Monday's session on climate, biodiversity and oceans at the G-7 summit in Biarritz, but didn't. French President Emmanuel Macron, the summit host, shrugged off the absence, noting that Trump's aides were there instead.

Trump is a climate change skeptic who once had claimed it's a hoax that was invented by the Chinese. His decision to withdraw the United States from the 2015 Paris climate accord has severely damaged global efforts to reduce emissions.

Trump started the morning behind schedule, and held one-on-one meetings while others were in the climate discussions. However, his interlocutors, German Chancellor Angela Merkel and India's Prime Minister Narendra Modi, managed to make it to the climate meeting.

Macron said it wasn't his goal to try to persuade Trump to rejoin the climate accord. "You can't rewrite the past," Macron told reporters.

But Macron said he and Trump had a "long, rich and totally positive" discussion on the Amazon fires and an international effort to invest in "re-foresting" the area.

G-7 countries pledged $20 million on Monday to help fight fires in the Amazon rainforest, which threaten its ability to capture carbon released into the atmosphere by cars and other emitters. It's a small sum overall but G-7 summit host France hopes it will bring more attention to the fires.

U.N. Secretary-General Antonio Guterres - who attended Monday's climate talks - expressed hope that Americans themselves would help fight climate change even if their president doesn't.

"I am very optimistic about American society and its capacity to deliver in relation to climate action," he told reporters afterward. "What matters here is to have a strong engagement of the American society and of the American business community and the American local authorities."
