U.N. Secretary-General Antonio Guterres took his global message urging immediate climate action to officials gathered in the United Arab Emirates on Sunday, where production of hydrocarbons remains a key driver of the economy.
Guterres is calling on governments to stop building new coal plants by 2020, cut greenhouse emissions by 45% over the next decade and overhauling fossil fuel-driven economies with new technologies like solar and wind. The world, he said, "is facing a grave climate emergency."
In remarks at a summit in Abu Dhabi, he painted a grim picture of how rapidly climate change is advancing, saying it is outpacing efforts to address it.
He lauded the Paris climate accord, but said even if its promises are fully met, the world still faces what he described as a catastrophic three-degree temperature rise by the end of the century.
Arctic permafrost is melting decades earlier than even worst-case scenarios, he said, threatening to unlock vast amounts of methane, a greenhouse gas.
"It is plain to me that we have no time to lose," Guterres said. "Sadly, it is not yet plain to all the decision makers that run our world."
He spoke at the opulent Emirates Palace, where Abu Dhabi was hosting a preparatory meeting for the U.N. Climate Action Summit in September. Guterres was expected to later take a helicopter ride to view Abu Dhabi's Noor solar power plant.
When asked, U.N. representatives said the lavish Abu Dhabi summit and his planned helicopter ride would be carbon neutral, meaning their effects would be balanced by efforts like planting trees and sequestering emissions. The UN says carbon dioxide emissions account for around 80% of global warming.
Guterres was in Abu Dhabi fresh off meetings with The Group of 20 leaders in Osaka, Japan. There, he appealed directly to heads of state of the world's main emitters to step up their efforts. The countries of the G20 represent 80% of world emissions of greenhouse gases, he said.
At the G20 meeting, 19 countries expressed their commitment to the Paris agreement, with the only the United States dissenting.
In 2017, President Donald Trump pledged to withdraw the U.S. from the Paris climate agreement as soon as 2020, arguing it disadvantages American workers and taxpayers. Trump has also moved steadily to dismantle Obama administration efforts to rein in coal, oil and gas emissions. His position has been that these efforts also hurt the U.S. economy.
The secretary-general's special envoy for the climate summit, Ambassador Luis Alfonso de Alba, told The Associated Press it was disappointing that the U.S. has pulled out from the accord. However, he said there are many examples of efforts at the local and state level in the United States to combat climate change.
"I think it is very important to have all countries committing to this cause... even more when we are talking about the country of the importance and the size - not only in terms of the economy but also the emissions - of the United States," he said.
Guterres is urging business leaders and politicians to come to the Climate Action Summit later this year with their plans ready to nearly halve greenhouse emissions by 2030 and reach carbon neutrality by 2050.
He suggested taxing major carbon-emitting industries and polluters, ending the subsidization of oil and gas, and halting the building of all new coal plants by next year.
"We are in a battle for our lives," he said. "But it is a battle we can win."
