SHARM EL-SHEIKH, Egypt (AP) 鈥 Envoys from around the globe gathered Sunday in the Egyptian seaside resort of Sharm el-Sheikh for talks on tackling climate change amid a multitude of competing crises, including the war in Ukraine, high inflation, food shortages and an energy crunch.

Notching up a first small victory, negotiators agreed after two frantic days of preliminary talks to formally discuss the question of vulnerable nations receiving money for the loss and damage they've suffered from climate change. The issue has weighed on the talks for years, with rich nations including the United States pushing back against the idea of climate reparations.

鈥淭he fact that it has been adopted as an agenda item demonstrates progress and parties taking a mature and constructive attitude towards this," said the U.N.'s top climate official, Simon Stiell.

鈥淭his is a difficult subject area. It鈥檚 been floating for thirty plus years,鈥 he said. "I believe it bodes well.鈥

The decision was also welcomed by civil society groups.

鈥淎t long last, providing funding to address losses and damages from climate impacts is on the agenda of the U.N. climate negotiations,鈥 said Ani Dasgupta, president of the World Resources Institute.

But he cautioned that participants 鈥渟till have a marathon ahead of us before countries iron out a formal decision on this central issue.鈥

German climate envoy Jennifer Morgan, who led negotiations on the issue together with Chile in the run-up to the talks, said the agreement could help negotiators also make 鈥渟erious progress鈥 on the issue of reducing emissions.

The outgoing chair of the talks, British official Alok Sharma, said countries had made considerable progress at their in keeping alive the goal of limiting global warming to 1.5 degrees Celsius (2.7 Fahrenheit) by the end of the century.

Experts say that chances of meeting that target, agreed in the 2015 Paris climate accord, is fast slipping away though. Already, temperatures around the world have increased by about 1.2 C (2.2 F) since pre-industrial times

Sharma warned that other global crises meant international efforts to curb climate change were being 鈥渂uffeted by global headwinds."

鈥(Russian President Vladimir) Putin鈥檚 brutal and illegal war in Ukraine has precipitated multiple global crisis, energy and food insecurity, inflationary pressures and spiraling debt,鈥 said Sharma. 鈥淭hese crises have compounded existing climate vulnerabilities and the scarring effects of the pandemic.鈥

鈥淎s challenging as our current moment is, inaction is myopic and can only defer climate catastrophe,鈥 said Sharma. 鈥淲e must find the ability to focus on more than one thing at once.鈥

"How many more wake up calls does the world to world leaders actually need,鈥 he said, citing recent devastating floods in Pakistan and Nigeria, and historic droughts in Europe, the United States and China.

His successor, Egyptian Foreign Minister Sameh Shoukry, said Egypt would 鈥渟pare no effort" to make the meeting in Sharm el-Sheikh a success and achieve the goals of the Paris accord.

In an opening speech, the chair of the Intergovernmental Panel on Climate Change, Hoesung Lee, said countries have 鈥渁 once in a generation opportunity to save our planet and our livelihoods."

Cutting emissions is only part of the task, however. Scientists and campaigners say the world also needs to do more to adapt to those effects of global warming that can't be avoided anymore.

The head of the U.N. migration agency urged the international community Sunday to mobilize human and financial resources to address growing climate migration.

Ant贸nio Vitorino told The Associated Press that millions of people across the world 鈥渁re already suffering in their daily lives because of the impacts of natural disasters and climate change.鈥

鈥淲e are running short of time to act,鈥 Vitorino said. 鈥淭he international community needs to mobilize the expertise, human resources but also the financial resources to come in to support those who are already today seriously impacted by climate change.鈥

Vitorino, IOM鈥檚 director general, said the world needs to double the $100 billion current funding for adaption especially in regions and communities impacted by the fast-changing climate.

鈥淚f we don鈥檛 focus on solutions for the future,鈥 he said. 鈥淲e will leave a dramatic humanitarian crisis in the future (that) will eat millions and millions of people in the world,鈥 he said.

More than 40,000 participants have been registered for this year's talks, reflecting the sense of urgency as major weather events around the world impact many people and cost billions of dollars in repairs. Organizers say about 110 world leaders will attend, many of them speaking at a high-level event on Nov. 7-8, while U.S. President Joe Biden was expected to arrive later in the week.

But many top figures including China's President Xi Jinping and Prime Minister Narendra Modi of India were not planning to come, casting doubt on whether the talks in Egypt could result in any major deals to cut emissions without two of the world's biggest polluters.

Rights groups again criticized Egypt for restricting protests and stepping up surveillance during the summit, and highlighted the case of Alaa Abdel-Fattah, . Abdel-Fattah鈥檚 aunt, award-winning novelist Ahdaf Soueif, said he and stopped drinking water at 10 a.m. local time.
