The U.N. climate summit in Glasgow formally opens Sunday, a day before leaders from around the world gather in Scotland’s biggest city to lay out their vision for addressing the common challenge of global warming.
The meeting will see negotiators from almost 200 countries try to tackle issues left hanging since the 2015 Paris climate accord was forged, and find ways to ratchet up their efforts to keep global temperatures from rising by more than 1.5 degrees Celsius (2.7 Fahrenheit) this century compared with pre-industrial times.
Scientists say the chances of meeting that goal, agreed in the French capital six years ago, are slowly slipping away. The world has already warmed by more than 1.1C and current projections based on planned emissions cuts over the next decade are for it to hit 2.7C by the year 2100.
The amount of energy unleashed by such planetary warming would melt much of the planet's ice, raise global sea levels and greatly increase the likelihood and intensity of extreme weather, experts warn.
“There has been progress over the last few years but I would say that actually the task we have here is in many ways tougher than Paris,” said Alok Sharma the British government minister chairing the Glasgow talks.
“What we’ve had to do since (Paris) is agree some of the detailed rules and some of the most difficult rules are still outstanding after six years, and that makes it really challenging," he told Sky News.
“Of course, we know that the geopolitics is more difficult than it was at the time of Paris," he said, adding that it was time for governments to “leave the ghosts of the past behind."
“What we need to come from Glasgow is to be able to say with credibility, ‘We have kept 1.5 alive,’” said Sharma.
He noted that China the world's biggest emitter of greenhouse gases, had just raised its climate targets somewhat.
"But of course we expected more,” Sharma told the BBC.
U.S. climate envoy John Kerry warned last week of the dramatic impacts that exceeding the 2015 Paris accord’s goal will have on nature and people, but expressed optimism that the world is heading in the right direction. The United States is currently the world's second biggest polluter, though historically it is responsible for the biggest amount of carbon dioxide in the atmosphere.
India, the world's third biggest emitter, has yet to follow China, the U.S. and the European Union in setting a target for reaching ‘net zero’ emissions. Negotiators are hoping India's Prime Minister Narendra Modi will announce such a goal in Glasgow.
“We need all of the G20 to come forward," said Sharma. "The G20 represents 80% of global emissions and that’s why every country matters, but the G20 matters particularly.”
Some of the issues being discussed during the Oct. 31-Nov. 12 talks have been on the agenda for decades, including how rich countries can help poor nations tackle emissions and adapt to a hotter world. The slow pace of action has angered many environmental campaigners, who are expected to stage loud and creative protests during the summit.
Speaking in Rome Sunday, Prince Charles urged world leaders to heed the “despairing voices” of young people who will bear the brunt of climate change.
The heir to the British throne described the talks in Glasgow as “literally the last-chance saloon” for the Earth.
Charles told Group of 20 leaders meeting in Rome that they have an “overwhelming responsibility to generations yet unborn.”
“It is impossible not to hear the despairing voices of young people who see you as the stewards of the planet, holding the viability of their future in your hands,” he said.
On Monday, Charles is due to welcome leaders to COP26 in Glasgow. His 95-year-old mother Queen Elizabeth II was due to attend but has been advised to rest by her doctors.
The opening day of the talks is expected to focus on procedural issues. One big worry is that not all the delegates will be able to meet in person, as the venue and room capacities have been limited due to COVID concerns.
