We are at the midpoint of this decade. Climate change is no longer a future threat—it is reshaping the present, daily, across every region of our world. 2026 is not simply another year of climate action. It is a decision point. Every commitment made at the global negotiating table must move from paper to implementation. Every goal set for 2030 now depends on what we do in the next four years. This is the year to measure whether we stand by our science, our institutions, and our promises.


1. The Physics Are Accelerating

The planet will not wait for us to act. New forecasts from the World Meteorological Organization (WMO) project that global temperatures from 2025 to 2029 will remain at or exceed record levels, likely 1.2°C to 1.9°C above the 1850–1900 baseline. There is a 70 per cent probability that the five-year average will breach critical warming thresholds.

The 1.5°C limit is no longer a future milestone. It is an overshoot we are already experiencing.


What does this mean on the ground? Every tenth of a degree translates to intensified heatwaves, more severe rainfall events, deeper droughts, accelerating ice loss, and rising sea levels. For nations in arid and water-scarce regions, particularly across Africa and South Asia, this is not theoretical. It is operational reality. Water systems strain. Agricultural productivity falters. Displacement accelerates.


The path forward is not about prevention anymore. It is about managing escalating risk and building resilience in real time.


2. COP 31: Moving from Commitment to Delivery

COP 30 in Belém delivered incremental wins, the Adaptation Indicators, the Just Transition Mechanism, and a tripling of adaptation finance commitments. These are not nothing. They are scaffolding.

COP 31 in Antalya, Türkiye (with Australia leading negotiations) must now convert these into operational reality. Two priorities dominate:


  • Climate Finance Architecture: The $1.3 trillion target for climate finance to developing nations by 2035 remains largely a framework without a delivery mechanism. How is this capital mobilized? Who administers it? What accountability structures exist? These are not philosophical questions, they are systems questions. They require governance, transparency, and ruthless execution.

  • Fossil Fuel Language: Despite weakened agreements at COP 30, the transition away from fossil fuel dependency remains unfinished business. The political headwinds are real. The corporate and national interests are entrenched. But the science does not negotiate. This language must evolve from aspirational to binding.


For emerging economies, particularly those with limited fiscal capacity, the credibility of global climate finance will determine domestic political viability of climate action.


3. Three Interconnected Global Crises, One Year

2026 hosts three critical United Nations conferences addressing land, biodiversity, and climate simultaneously:


  • UNCCD COP 17 (August, Ulaanbaatar): Land Degradation Neutrality (LDN), achieving no net loss of productive land by 2030. Focus: grassland restoration and water scarcity adaptation in arid regions.

  • CBD COP 17 (October, Yerevan): Assessing progress on the Kunming-Montreal Global Biodiversity Framework. Twenty-three 2030 targets are under review.

These are not separate problems. They are expressions of the same root challenge: how we use land, manage ecosystems, and sustain the living systems that underpins human survival.


The Rio Trio initiative (launched in 2024) is attempting to coordinate action across these frameworks. This coordination is essential. Siloed action fails. Systems thinking wins.


4. Cities Are the Battleground

Cities account for 70 per cent of global greenhouse gas emissions. They are also the largest gaps in climate governance, often moving faster and more decisively than national governments.

The World Urban Forum in Baku (2026, theme: "Housing the World: Safe and Resilient Cities and Communities") brings global city decision-makers together on a singular crisis: the global housing shortage and the imperative of sustainable, resilient urban development.

Cities have the advantage: local authority, faster decision cycles, ability to pilot and iterate. They have the constraint: dependence on national governments for enabling policy, regulatory support, and climate finance access.

The work in 2026 is to clarify how cities can deepen climate action while pressing national governments to remove barriers and unlock capital. This is a negotiation, not a gesture.


5. Science as Infrastructure

The United States withdrawal from the IPCC and IPBES represents a strategic disengagement from global scientific coordination at a moment when credible, shared knowledge is indispensable.

The IPCC and IPBES serve a singular function: rigorous assessment of evidence on climate drivers, risks, and solutions. They are not advocacy bodies. They are information infrastructure.


Disengaging from these processes does not eliminate the underlying science. It eliminates shared access to credible guidance. It creates fragmentation. It leaves policymakers, businesses, and citizens without common reference points.

In 2026 and beyond, the global reaffirmation of scientific collaboration is as much a systems and governance priority as any emissions reduction target. Without shared knowledge, coordinated action is not possible.


The Year Ahead

2026 is not a year of promises. It is a year of accounting. Implementation will be tested. Political will will be exposed. The credibility of global institutions will be measured against action, not intention.

Every fraction of a degree matters. Every institution we maintain matters. Every commitment we keep or fail to keep establishes the baseline for what 2030 will hold.
