The climate negotiations opening in Antalya, Türkiye, arrive at a moment when the physical evidence is becoming harder to ignore and the politics harder to manage. Scientists forecast that 2026 is likely to become the hottest year on record, while the World Meteorological Organization expects it to rank among the four warmest years ever measured. The timing gives COP31 a stark backdrop: the summit is being asked not simply to raise ambition, but to demonstrate that governments can convert commitments into action. BBC
Nearly 200 countries and more than 90,000 participants are expected in Antalya. The agenda includes climate finance, adaptation, clean energy and a “just transition” for workers and communities affected by the shift away from fossil fuels. The central question is whether governments can resolve disputes over who pays, how quickly money can be accessed and how much responsibility should fall on countries with the largest historical emissions.

Why this summit matters
The forecast for 2026 is not, by itself, evidence that the Paris Agreement has failed. One unusually hot year can be amplified by El Niño, the natural Pacific Ocean phenomenon that temporarily raises global temperatures. But the underlying trend is unequivocal: each additional increment of warming increases the likelihood of dangerous heat, heavy rainfall, drought and disruption to food and water systems.
That distinction matters politically. Governments can argue that short-term temperature records reflect natural variability, but they cannot use El Niño to explain away the long-term rise caused primarily by greenhouse-gas emissions. Climate diplomacy is therefore operating on two time scales: reducing emissions quickly enough to limit future warming, while adapting to impacts that are already unavoidable.
The WMO’s more cautious forecast still places 2026 among the warmest years on record, reinforcing the broader scientific message. The debate is no longer whether warming is occurring, but how much additional damage can be avoided and how fairly its costs will be distributed. BBC
Finance is the political fault line
Developing countries are pressing for faster and more accessible climate finance, particularly for adaptation. Their argument is straightforward: many of the most vulnerable states contributed relatively little to cumulative emissions, yet face rising costs from floods, heat, storms and sea-level rise. They want grants or highly concessional loans, rather than debt that deepens existing fiscal pressures.
Wealthier governments accept the need for support but face domestic constraints, competing security priorities and disagreement over the donor base. Some argue that rapidly growing economies should contribute more, while developing countries counter that this must not dilute the historical responsibility of industrialised nations. The result is a familiar deadlock: broad agreement on the need for finance, but no consensus on scale, sources or accountability.
UN officials say finance is expected to be among the most difficult issues at COP31. Negotiators are being encouraged to shape a political agreement early rather than postponing every decision until the summit’s final hours, an approach intended to avoid the last-minute compromises that have weakened confidence in previous conferences.

Energy security changes the argument
The energy transition is also being reshaped by geopolitics. The conflict in Iran has effectively closed the Strait of Hormuz, according to Associated Press reporting, raising prices for oil and petroleum-based products including fertilisers and pesticides. The disruption has given governments a new reason to reduce dependence on imported fossil fuels: not only emissions, but exposure to strategic chokepoints and price shocks. Associated Press
That does not mean the transition will be politically painless. Higher energy costs can provoke public opposition, especially where households already face pressure on real incomes. Fossil-fuel producers and energy-intensive industries warn that rapid restrictions could damage competitiveness and employment. Supporters of faster decarbonisation respond that renewable power, efficiency and storage can reduce exposure to volatile fuel markets, provided governments invest in grids and protect vulnerable consumers.
What comes next
The most meaningful outcome from COP31 will not be the rhetoric of its opening speeches. It will be whether countries establish measurable pathways for finance, accelerate permitting and grid investment, and strengthen adaptation plans that can be evaluated publicly. A deal that repeats long-term targets without delivery mechanisms would preserve diplomatic unity but do little to alter emissions or vulnerability.
Economic conditions add another constraint. The OECD projects global growth of 2.9% in 2026 and 3.0% in 2027, with higher interest rates and weaker real-income growth moderating activity. At the same time, it says strong artificial-intelligence-related investment and an assumed easing of energy prices could support growth. Governments will therefore judge climate measures through an economic lens: policies that create jobs, lower energy risk and attract investment will be easier to sustain than those perceived as immediate costs without visible benefits.

COP31 cannot settle every dispute between rich and poor countries, nor eliminate the geopolitical risks driving energy markets. It can, however, reveal whether climate cooperation is adapting to a harsher reality. The test is practical: whether promises become money, infrastructure and emissions cuts before another record-hot year makes the gap still wider.
