On Tuesday, Johan Rockström stood at the Reuters Sustainability Europe conference in London and delivered a summation that no amount of diplomatic framing could soften. Global warming is accelerating, he said. The rate has roughly doubled — from 0.19°C per decade between 1970 and 2010, to 0.36°C per decade from 2010 to the present. Damage to coral reefs and the Amazon rainforest is close to becoming irreversible. Parts of the Atlantic Ocean’s circulation system, including the current that moderates Western Europe’s climate with warm water from the Caribbean, are close to collapse. The world is on course to exceed 1.5°C of warming in the next few years. Rockström is not a fringe voice. He is the director of the Potsdam Institute for Climate Impact Research, one of the most cited climate scientists in the world, and he was speaking 19 days before COP31 opens in Antalya, Turkey.
The annual UN climate summit — running from November 9 to 20, 2026, with a World Leaders’ Summit on November 11 and 12 — arrives in the worst possible position for a meeting that needs to prove the world can move from pledging to delivering. The science is unambiguous and accelerating. The diplomatic architecture is fragile. The political conditions in the major emitting economies have not improved since Belém. And the expectations, set deliberately low by the EU and others who watched last year’s COP30 end without any wording on fossil fuels, are lower still for Antalya.

The Science Delegates Are Walking Into
The BioScience State of the Climate report, published October 14, surveyed 16 planetary system indicators and found negative trends across every one of them. Atmospheric CO₂ has reached 428 parts per million. Methane is approaching 2,000 ppm. Nitrous oxide is at 340 ppm. Surface temperature anomaly has reached approximately 1.5°C above pre-industrial levels — the threshold the Paris Agreement established as the upper limit of acceptable warming. Ocean heat content is at record levels. Ocean acidity, measured in pH, has fallen to 8.050, threatening marine ecosystems at the base of global food chains.
Rockström’s acceleration point is the report’s most alarming finding in operational terms. A warming rate of 0.36°C per decade means the world is no longer in a slow-moving crisis that allows for decades of incremental policy adjustment. It is in a fast-moving one that requires policy delivery on a timeline that the current pace of COP negotiations has never matched. The last five COPs have each ended with some form of acknowledgment that more ambition is needed. None has produced the binding implementation mechanism that the science has been calling for since Paris in 2015.
The AXA Future Risks Report, published two days before Rockström’s speech, captured something equally significant about the political environment those scientists are operating in: for the first time in seven years, climate change has fallen from the number-one position in experts’ risk rankings — displaced by artificial intelligence and big data. The general public still rates climate as the top risk. The experts who advise governments and corporations have moved AI up. That perceptual shift matters because it describes the attention economy in which climate policy is now competing — and losing ground.
The Architecture of COP31: Two Countries, One Fragile Compromise
COP31’s governing structure is itself a story of geopolitical friction. After a week of competing bids in November 2025, Turkey and Australia could not agree on which country should host — and produced a compromise that has raised concerns about coherence and accountability ever since.
Turkey holds the COP31 Presidency through Environment Minister Murat Kurum, hosts the summit at the Antalya Expo Center, and carries responsibility for the action agenda. Australia runs the formal negotiations through Climate Minister Chris Bowen, who serves as President of Negotiations for the duration. The pre-COP meeting was held in Fiji, with a leaders’ event in Tuvalu — a deliberate choice by the Australia-Pacific partnership to place Pacific island vulnerability at the center of the conversation before the main summit begins.
The split presidency has generated real concern. An EU official, speaking to RTÉ on condition of anonymity, put it plainly: “It would be counterproductive to arrive with overly high expectations and end up disappointed.” The European Commission has circulated an internal communication strategy that frames ambition carefully, explicitly noting that presenting the absence of a breakthrough as failure would be counterproductive — language that reads less like diplomatic caution and more like a managed retreat from the expectation of meaningful outcomes.
Turkey’s own climate credentials are mixed. The country has enacted a Climate Law — in force since July 9, 2025 — and published an Emissions Trading System regulation in August 2026. These are genuine policy steps. They arrive in a context where Turkey is also a major natural gas transit state with economic interests that do not align cleanly with the energy transition agenda at the center of COP31’s thematic days.
Australia, despite its co-presidency, is an economy whose resources sector has lobbied aggressively against domestic emissions constraints — and whose government has been trying to balance its role as a global climate negotiations leader with a domestic political economy that is highly sensitive to energy transition costs in resource-dependent regions.
What the Agenda Actually Requires
COP31’s official agenda describes its task with unusual clarity for a UN conference: “Antalya’s task is less about drafting new ambitions and more about proving the last round of promises can be kept before 2030 arrives.”
The specific deliverables on the table include progress on the New Collective Quantified Goal for climate finance — the successor to the $100 billion annual commitment that rich countries promised developing nations in 2009 and consistently failed to meet. After Belém, which set a new framework but left the numbers and mechanisms underspecified, Antalya is expected to operationalize the finance flows, scale up adaptation funding, and strengthen the loss and damage mechanism that was established at COP28 to compensate vulnerable countries for climate impacts they did not cause.
The Agenda
The energy agenda is structured around a 35% electrification target for final energy demand by 2035 — an ambition that confronts the most direct bottleneck in the transition: the power grid. Grid infrastructure investment globally is running well below the level required to absorb the renewable energy capacity being added. Clean energy deployment continues to grow, but the transmission and distribution infrastructure connecting that generation to end users has not kept pace, creating a situation in which renewable capacity additions are not translating into renewable energy consumption at the rate the climate math requires.
Methane reduction is a second critical track, given that methane’s short-term warming potential makes it one of the most effective near-term levers available. The Global Methane Pledge, launched at COP26, committed signatories to a 30% reduction by 2030. Progress toward that target has been inadequate, and Antalya is expected to sharpen the accountability mechanisms — though the absence of major methane emitters from the pledge’s signatory list, including several large oil and gas producers, limits what accountability mechanisms can achieve without those countries in the room.
The “Belém Mission to 1.5°C” report, required to be published before COP31, will provide the scientific checkpoint against which negotiators’ claims of progress will be measured. Based on the BioScience indicators and Rockström’s October 20 assessment, that checkpoint is unlikely to show the trajectory bending toward Paris Agreement commitments.
The Political Headwinds
The diplomatic headwinds arriving in Antalya are the strongest of any COP since the Paris Agreement itself.
The United States
The United States enters the conference without a coherent federal climate policy framework. The Trump administration’s withdrawal from the Paris Agreement’s implementation architecture, its prioritization of domestic fossil fuel production, and its framing of international AI oversight as a “globalist scheme” — language that extends to multilateral climate commitments by implication — mean the world’s second-largest emitter is functionally absent from the negotiating room in any constructive sense.
The EU
The EU arrives having watered down significant elements of its own Green Deal legislation under domestic political pressure. The European Commission official’s pre-summit language about managed expectations reflects a body that spent the year defending already-passed legislation against regulatory rollback rather than advancing new ambition. EU climate credibility — the bloc’s primary diplomatic asset in COP negotiations — has taken real damage from that defensive posture.
France
France’s domestic political climate adds an acute current-events dimension to the broader trend. Today, Italy has deployed 500 troops to Milan after days of protests and looting. France has announced nightly curfews in Paris and other major cities, with analysts linking the unrest directly to “the global climate fiasco” and specifically to sweltering school conditions that the government has failed to address through adaptation funding. The political instability driven partly by climate-related grievances in two major European democracies is not an abstraction — it is the kind of domestic pressure that historically either forces ambition at climate summits or prevents governments from taking politically costly positions.
China
China, the world’s largest emitter, has signaled that its COP31 engagement will be shaped significantly by the state of its relationship with the United States — a relationship that, following the September White House summit between Trump and Xi, remains functional at the trade level but contested on technology, security, and climate governance.
What Success Would Look Like
A successful COP31 would produce three things: a credible operationalization of the climate finance mechanism that actually moves money from wealthy emitters to vulnerable nations; a strengthened loss and damage framework with defined disbursement pathways; and a methane accountability structure with teeth sufficient to close the gap between the Pledge’s signatories and the countries where the reductions actually need to happen.
None of these outcomes is impossible. Each requires political will from parties whose domestic political incentives run against incurring the costs that delivery requires.
The more likely outcome, based on the EU’s deliberately tempered expectations and the UNFCCC secretariat’s own pre-COP warning about “blockages,” is an Antalya agreement that advances implementation language on finance and adaptation, falls short on fossil fuels — as Belém did — and defers the accountability mechanisms that would make the commitments measurable.
That outcome would be nothing. It would be a continuation of the incremental progress that each COP has managed to produce. And it would be arriving in a year when global warming’s rate has doubled, 1.5°C has been reached at the surface, the Atlantic circulation is approaching tipping points, and France is under curfew partly because the government failed to cool its schools.
The gap between what the science requires and what the politics is likely to deliver has never been wider, or more consequential. Antalya will not close it. The question is how much of it COP31 can narrow — and whether the answer is enough.
