UN climate summit formally opens in Glasgow

The UN climate summit in Glasgow has formally opened, kicking off two weeks of intense diplomatic negotiations by almost 200 countries on how to tackle the common challenge of global warming.

Following Sunday's opening gavel, officials began addressing a raft of procedural matters before leaders from around the world gather in Scotland's biggest city Monday to lay out their countries' efforts to curb greenhouse gas emissions and deal with the effects of climate change.

Many 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.

The outgoing president of the meeting, Chile's Carolina Schmidt, started the talks by asking officials to observe a minute's silence for those who have died due to the coronavirus pandemic since the last UN climate conference was held in late 2019, shortly before the outbreak began.

The summit 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 C 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 1.1 C and current projections based on planned emissions cuts over the next decade are for it to hit 2.7 C 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.
