Leaders buffeted by the geopolitical crosswinds or war and economic turmoil meet in Egypt Monday at a climate summit tasked with taming the terrifying juggernaut of global warming.

Expectations are running high in a world justifiably anxious about its climate-addled future as deadly floods, heat waves and storms across the planet track with worst-case climate scenarios.

The November 6-18 gathering of nearly 200 nations in Sharm el-Sheikh will be dominated by the growing need of virtually blameless poor nations for money to cope not just with future impacts, but those already claiming lives and devastating economies.

Without a "historic pact" bridging the North-South divide, "we will be doomed, because we need to reduce emissions, both in the developed countries and emerging economies," UN chief Antonio Guterres said Thursday.

Last week the UN warned that "there is no credible pathway in place" for capping the rise in global temperatures under the Paris Agreement target of 1.5 degrees Celsius.

While worst-case projections are less dire than a decade ago, current policies would still see Earth's surface warm a catastrophic 2.8C, and no less than 2.4C even if countries meet all their carbon-cutting pledges under the Paris treaty.

"There have been fraught moments before," said E3G think tank senior analyst Alden Meyer, recalling other wars, the near collapse of the UN-led process in 2009, and Donald Trump yanking the United States out of the Paris Agreement in 2016.

"But this is a perfect storm," dubbed by some a "polycrisis", said the 30-year veteran of the climate arena.

Casting an even longer shadow on negotiations in Egypt than Russia's invasion of Ukraine, many experts say, is the further erosion of Sino-US relations, which in the past have anchored breakthroughs in climate diplomacy, including the Paris Agreement.

- 'Watershed moment' -

But a Taiwan visit in August by US congressional leader Nancy Pelosi prompted Beijing to shut down bilateral climate channels. Sweeping restrictions imposed last month by the Biden administration on the sale of high-level chip technology to China deepened the rift.

"We are at a watershed moment," said Li Shuo, a Beijing-based policy analyst with Greenpeace International.

"If the politics are so bad that the world's two biggest emitters won't talk to each other, we're not going to get to 1.5C."

A bilateral meeting between US President Joe Biden and Chinese leader Xi Jinping during the G20 summit in Bali days before the talks in Egypt close, should it happen, could move the dial, Li observed.

"That dynamic would play back to Sharm el-Sheikh."

Biden will arrive in Egypt touting the landmark Inflation Reduction Act (IRA), which earmarks nearly $400 billion -- and potentially twice that amount -- to speed the greening of the US economy.

But legislative elections on November 8 could dampen US bragging rights if Republicans hostile to international climate action take either or both houses of Congress.

A bright spot at COP27 will be the arrival of incoming Brazilian president Luiz Inacio Lula da Silva, who has vowed to aim for zero deforestation in the Amazon, reversing the extractive policies of Jair Bolsonaro, who will step down on January 1.

- Money matters -

COP27 will arguably boil down to a trio of interlocking priorities: emissions, accountability and money.

The creation of a separate pool of capital for "loss and damage" -- UN climate lingo for unavoidable and irreversible climate damages -- could be a make-or-break issue.

"This discussion has been going on for three decades," UN climate change chief Simon Stiell told journalists Friday. "The most vulnerable countries are tired, they are frustrated."

The US and the European Union -- fearful of open-ended reparations -- have dragged their feet on this issue for years and question the need for a separate financial framework.

"The success or failure of COP27 will be judged on the basis of whether there is agreement on a financing facility for loss and damage," Munir Akram, Pakistan's UN ambassador and chair of the powerful G77+China negotiating bloc of more than 130 developing nations, told AFP.

Rich nations will also be expected to set a timetable for the delivery of $100 billion per year to help developing countries green their economies and build resilience against future climate change.

The promise is already two years past due and remains $17 billion short, according to the OECD.

Last year's COP26 in Glasgow prioritised reducing carbon pollution, mostly through sideline agreements orchestrated by host Britain to curb methane emissions, halt deforestation, phase out fossil fuel subsidies and ramp up the transition to renewable energy.

Nations agreed to review their carbon-cutting pledges annually and not just every five years, though only a handful of nations have done so in 2022.

Guterres, meanwhile, will unveil a critical assessment of "net-zero" commitments by companies, investors and local governments to become carbon neutral.

"Our world cannot afford any more greenwashing, fake movers or late movers," he said last week.

Kerry sees Brazil, Mexico rising climate hopes ahead of summit
Washington (AFP) Nov 2, 2022
US climate envoy John Kerry said Wednesday he expects bold new action by Mexico and Brazil's next government, raising hopes of achieving progress at this month's global warming summit in Egypt. Kerry also gave his firmest indication yet that the United States was willing to engage on compensating poor nations that have already been hit hard by climate change, set to be a major agenda item at the talks known as COP27. In Brazil, where the Amazon plays a vital role counteracting the planet's carbo ... read more
