PARIS: World leaders will launch an ambitious attempt on Monday to hold back the earth’s rising temperatures, urging each other to find common cause in two weeks of bargaining meant to steer the global economy away from dependence on fossil fuels.
Some 150 heads of state, including U.S. President Barack Obama and his Chinese counterpart Xi Jinping, were arriving at United Nations climate change talks in Paris armed with promises and accompanied by high expectations.
After decades of struggling negotiations marked by the failure of a previous summit in Copenhagen six years ago, some form of landmark agreement appears all but assured by mid-December.
Warnings from climate scientists, demands from activists and exhortations from religious leaders like Pope Francis, coupled with major advances in cleaner energy sources like solar power, have all added to pressure to cut the carbon emissions held responsible for warming the planet.
Most scientists say failure to agree on strong measures in Paris would doom the world to ever-hotter average temperatures, bringing with them deadlier storms, more frequent droughts and rising sea levels as polar ice caps melt.
Facing such alarming projections, the leaders of nations responsible for about 90 percent of the world’s greenhouse gas emissions have come bearing pledges to reduce their national carbon output, though by different rates.
For some, it has already become a pressing issue at home. As the summit opened in Paris, the capitals of the world’s two most populous nations, China and India, were blanketed in hazardous, choking smog, with regulators in Beijing asking factories to limit output and halting construction work.
Achieving what would be by far the strongest international agreement yet to commit both rich and developing nations to the fight against global warming would mean “we can have confidence that we’re doing right by future generations,” U.S. President Barack Obama said earlier this month.
French Foreign Minister Laurent Fabius, chairman of the meeting, urged delegates to work hard so that they could say “mission accomplished” by Dec. 11. “Success is not yet achieved, but it is within reach,” he told delegates.
On the eve of the summit, hundreds of thousands of people from Australia to Paraguay joined the biggest day of climate change activism in history, telling world leaders there was “No Planet B” in the fight against global warming.
“This past year has been a turning point,” Christiana Figueres, the U.N.’s climate chief, told delegates.
The leaders will gather in a vast conference centre at the Le Bourget airfield, near the spot where Charles Lindbergh landed his Spirit of St. Louis aircraft in 1927 after making the first solo trans-Atlantic flight, a feat that helped bring nations closer.
Whether a similar spirit of unity can be incubated in Le Bourget this time is uncertain. In all, 195 countries are part of the unwieldy negotiating process, espousing a variety of leadership styles and ideologies that has made consensus elusive in the past.
Key issues, notably how to divide the global bill to pay for a shift to renewable energy, are still contentious.
Signaling their determination to resolve the most intractable points, senior negotiators sat down on Sunday, a day earlier than originally planned, to begin thrashing out an agreement. They hope to avoid the last-minute scramble and all-nighters that marked past meetings.
The last attempt to get a global deal collapsed in chaos and acrimony in Copenhagen in 2009. It ended with Obama forcing his way into a closed meeting of China and other countries on the gathering’s last day and emerging with a modest concession to limit rising emissions until 2020 that they attempted to impose on the rest of the world.
Anxious to avoid a re-run of the Copenhagen disaster, major powers have tried this time to smooth some of the bumps in the way of an agreement before they arrive.
