This year’s so-called “super El Niño” is entering into record-breaking territory.
Sea surface temperatures in the tropical Pacific now equal the previous daily record set in 2015 and will likely keep rising in the days ahead.
El Niño is a naturally occurring climate phenomenon in the Pacific that reshapes weather patterns around the world and temporarily boosts global temperatures.
The current El Niño event – which has been underway since June and is expected to last until next year – has been developing faster than any previous event on record.
The strength of an event is tracked using the “Niño 3.4 anomaly”, which measures how much warmer sea surface temperatures in a section of the central Pacific are than average.
As of 19 September, the daily anomaly in the Niño 3.4 region stands at 3.07C, putting it in a statistical tie with the previous record of 3.08C.
Some scientists, using a different baseline for calculating the anomaly, have already called the new record.
Either way, this is remarkable, in part because of how early in the calendar year it is occurring. El Niño typically peaks in the winter months, most commonly in November or December.
Every strong El Niño on record has continued to strengthen after mid-September – and there is every reason to think that this one will as well.
(For more on El Niño, see Carbon Brief’s recent interactive explainer.)
Record territory
El Niño events are typically classed as “weak” when the Niño 3.4 anomaly reaches 0.5C, “moderate” above 1C, “strong” above 1.5C and “very strong” above 2.0C.
For this year’s event, the Niño 3.4 anomaly has now reached 3.07C, which puts it in a statistical tie with the record set on 18 November 2015, set during a “very strong” El Nino event.
The chart below shows how the strength of the current El Niño (red line) is dramatically outpacing both 2015-16 (blue) and another “very strong” event in 1997-98 (light blue).

To analyse the developing El Niño, Carbon Brief followed the convention of the US National Oceanic and Atmospheric Administration’s (NOAA) Oceanic Niño index (ONI).
ONI is calculated by subtracting the latest 30-year average temperature in the Nino 3.4 region from daily sea surface temperatures. This approach allows for the most recent years to be compared against the most recent 30-year period. It removes much of the influence of longer-term, human-driven warming from the index.
(While meteorological organisations typically track changes to ONI on a three-month rolling average basis, Carbon Brief’s analysis looked at how the metric is changing on a daily basis.)
If ONI is calculated using a baseline of 1991-2020 then the current El Niño has already set a new record.
Since the start of June, El Niño’s strength has been greater than any other year. In early September in both 1997 and 2015, anomalies were around 1.9C – more than one degree below where they are this year.
An alternative index
There is another commonly used metric – the relative Oceanic Niño index (RONI) – used to study El Niño.
Introduced by NOAA in 2024, the RONI index adjusts for tropical ocean warming linked to human-caused climate change. To do this, it takes sea surface averages in the Nino 3.4 region and subtracts out temperature anomalies observed across the tropical oceans (between the latitudes of 20 degrees north and south).
This approach may better remove the influence of climate change in this specific region, but can also diminish the apparent strength of strong El Niño events, such as the current one, which extend well outside the Niño 3.4 region.
The chart below shows daily RONI values, which are record setting for this time of year, but remain below an all-time daily record set during the 1982-83 El Niño event.

RONI stood at around 2.5C in mid-September, some 0.7C below the 1982 record.
However, that record was set in late December, at the peak of the event.
The 1982-83, 1997-98 and 2015-16 events added between 0.5C and 1.9C to their RONI values between mid-September and their peaks.
On track to smash monthly and seasonal records
Because daily El Niño values are noisy, scientists typically turn to monthly or seasonal averages to compare El Niño events.
The latest full calendar month for which data is available – August 2026 – had a Niño 3.4 anomaly of around 2.45C. This is higher than the peak of every prior El Niño event on record except 2015-16 – where the anomaly reached 2.75C – and 1877-78, when the anomaly sat at around 2.7C, based on a reconstruction of sea surface temperatures using sparse ship data.
The figure below shows the monthly evolution of the five strongest El Niño events on record alongside 2026, as well the current forecast from 14 seasonal forecast models.

Taken together, the models project a peak monthly anomaly later this year of around 4.1C, with 80% of the 674 individual model runs falling between 3.4C and 4.6C.
Every single model run peaks above the 2015-16 record. The projected margin over that record, some 1.3C, is larger than the entire gap between the strongest and fifth-strongest El Niño of the past 150 years.
Some caution here is warranted, however. No seasonal forecast system has ever been verified against an event of this size, because none has ever occurred. The models also predicted temperatures slightly warmer than observed this summer, with real-world observations for August coming in around 0.3C below forecasts.
However, all strong El Niño events on record have continued to strengthen well into the winter – and the models are in near-unanimous agreement that this one will, too. If the forecast holds, the current event will peak between November and January at a level far beyond any event previously observed in the instrumental record.
El Nino’s effect on global temperatures typically lags rising ocean temperatures in the Pacific by several months, so most of the impact will be felt in 2027 rather than 2026.
Carbon Brief’s most recent “state of the climate” quarterly analysis found 2026 on track to be the warmest or second-warmest year on record. The next update in early October will examine what a record El Niño means for 2027.

COP31 presidency announces AI pledge as UN climate chief says Big Tech ‘on thin ice’
Artificial intelligence (AI) is set for a bigger role at this year’s UN climate summit, as Türkiye’s COP31 presidency seeks backing for a new pledge on the technology’s energy use.
In a statement on Monday, the COP31 hosts said they will launch the Antalya Pledge on AI, which they billed as a “political” commitment on how AI is “designed, procured, powered, deployed, measured and managed” in support of climate action.
“We must openly discuss AI’s growing energy consumption and it is time for governments to start setting the terms,” COP31 president Murat Kurum said in an emailed statement. “We expect companies to be transparent about their energy use and to power their operations with clean energy”.
No further details about the pledge have been made available so far, including whether it will include a clean energy commitment or whether governments and companies will be invited to sign on. The COP31 presidency said it would share a draft before the summit opens in Antalya in early November.
UN climate chief Simon Stiell went further in a New York speech on Monday, warning that AI leaders are “on thin ice when it comes to license to operate, and sinking deep underwater when it comes to public support”.
“Energy-guzzling artificial intelligence is driving up planet-heating pollution from coal, oil and gas, while ratcheting up energy costs for households and businesses,” he said, adding that data centre projects are being put on hold due to public opposition from New York to Texas.
Growing energy use and emissions
Concerns about the environmental impacts of AI infrastructure and its impact on rising electricity prices have led to a growing backlash in some communities, especially in the US.
Big Tech’s breakneck race to develop new AI models and build out the energy-hungry infrastructure supporting them has stoked fears over the technology’s growing climate impact.
Greenhouse gas emissions generated by data centres through their electricity use are set to more than double between 2024 and 2030, according to the International Energy Agency (IEA).
Data centres, which underpin various technologies including AI, are expected to consume more power than all but five countries by the end of the decade.
The AI race is also driving a surge in new fossil gas investment in the United States, where Big Tech giants including Microsoft, OpenAI and Meta have struck up major deals with fossil fuel operators to power their infrastructure.
In China, the other major global AI force, coal provides around 70% of the electricity powering the country’s data centers, according to an IEA report published last year.
More space for AI at COPs?
Despite AI’s rapidly growing relevance for the world’s ability to limit global warming, high-level discussions on the climate impact of the technology have been largely absent at UN climate summits.
While the pledge is still being developed and scarce details have been made public so far, the Antalya initiative, alongside sharper rhetoric from Stiell, suggests that might be changing.
Climate Home News understands that the UN climate change body is encouraging AI companies to be present at COPs as the climate summits set the global direction for energy policy and tech firms now have a major stake in it.
Earlier this year, UN Secretary-General António Guterres launched an initiative aimed at holding AI companies accountable for their environmental impacts and repeated a call for all big AI companies to commit to powering every data centre with renewable energy by 2030.
Align AI with science
Stiell said that tech titans need to start showing why the benefits of AI outweigh its “skyrocketing costs”, by setting credible climate targets, coming clean about their energy use and powering data centres with renewable energy.
AI proponents claim that, despite its growing energy use, the technology’s widespread application would bring net benefits in the fight against climate change by driving massive energy efficiency gains and optimising renewable energy integration. The IEA estimates that existing AI applications could cut emissions by more than data centres add.
Fossil fuel expansion threatens COP31 hosts’ credibility, experts warn
But critics argue that it is wrong to compare theoretical gains with real-world emission growth and any gains are outweighed by the widespread adoption of AI tools by fossil fuel companies to extract planet-heating oil and gas faster and more cheaply.
Stiell said the tech industry needs to “respect science and start aligning with global climate efforts – urgently”.
Alongside the AI pledge, the COP31 presidency has also announced it will launch an ‘AI for Clean Technologies’ Initiative, which will develop a portfolio of AI-enabled clean-technology pilots in priority sectors, including smart energy and green industry.
This programme aims to demonstrate the responsible use of AI in practice, the COP31 presidency promised.

Why the global electrification agenda misses the point on Africa’s energy crisis
Dola Oluteye, PhD, is a senior fellow in energy and transport policy at the UCL Energy Institute and founder of The Professional African Network Advisory Initiative.
At the June 2026 UN Climate Meetings in Bonn, the incoming Turkish COP31 Presidency introduced a headline target for the Action Agenda: raising electricity’s share of global final energy consumption from around 20% today to 35% by 2035.
Backed by the international Electrify Now campaign – also launched in June by the European Commission and governments across five continents, including Ethiopia – the aim is to replace fossil fuels with clean energy by shifting the way we travel and transport goods and commodities, cook and warm our homes and offices, and power our industries.
On paper, this is a welcome signal. Yet, as world leaders line up behind global goals in the lead-up to COP31, African nations face a fundamental question: whose energy transition are we talking about? For the roughly 600 million people living without electricity on the continent, international climate targets often sound less like a lifeline and more like a conversation happening on another planet.
For developed countries, electrification is largely a replacement exercise – swapping petrol and diesel vehicles for electric ones, and gas boilers for heat pumps powered by existing, stable grids.
But across sub-Saharan Africa, the challenge is vastly different. The region accounts for 85% of the global population without electricity, up from 50% in 2010. Here, electrification is not a technology swap; it is the foundational building block of human dignity, economic sovereignty, energy access and modern development.
Electricity connections must deliver real development
Half of the number of people without electricity access in Africa live in three countries – Nigeria, Ethiopia and the Democratic Republic of Congo – while 900 million other Africans lack clean cooking solutions.
The proposed global electrification goal must not treat a continent with nearly half of its population without electricity the same way it treats mature Western economies.
To regard electrification merely as a tool for decarbonisation misses the core reality of our continent. Africa is not just transitioning an existing energy system; we are building one from the ground up in many places.
If a global electrification target of 35% by 2035 is to mean anything for Africa, it must be rooted in African realities. That begins with acknowledging that expanding power connections alone is insufficient.
China’s industrial engine starts to break its fossil fuel habit
Energy poverty does not end when a power line crosses a village; it ends when electricity is reliable, affordable and powered by clean sources that spur productive economic activities. Connecting households to a micro-grid they cannot pay to use does not deliver development.
Electrification can also help solve the critical issue of super pollutants in countries like Nigeria, notably the production of methane and black carbon, by replacing combustion-based systems with cleaner, electric alternatives.
Breaking from past extractive models
Equally critical is how the electricity is generated. Within some African policy circles, electrification has occasionally been viewed with scepticism – seen as a possible Trojan Horse to justify expensive nuclear projects or to expand long-term fossil gas lock-ins.
We must be clear: expanding electricity demand while increasing reliance on volatile fossil fuels or unviable, high-cost infrastructure is a false solution.
True electrification must be paired directly with the massive development of Africa’s unparalleled renewable energy resources.
Africa holds 60% of the world’s best solar resources, alongside immense hydro, wind and geothermal potential. Tying the global electrification push to renewable energy capacity and local battery storage is the only pathway that protects African economies from international fuel price shocks while keeping our climate commitments intact.
Global climate negotiations such as those ongoing at the International Maritime Organization (IMO) offer another building block for Africa’s green energy future.
International trade linked to 20% of global emissions – but imports ignored
Adopting a shipping carbon price at the IMO this year, through the Net-Zero Framework, would create a climate fund worth $12 billion a year. This finance could be used not only towards the electrification of Africa’s ships and ports, but also for building broader renewable energy production on the continent.
Furthermore, global initiatives must break from past extractive models. Africa cannot remain merely a site for extracting critical minerals – such as lithium, cobalt, and copper – to feed green supply chains elsewhere, only to import expensive finished technologies.
An authentic, inclusive campaign must support the development of local industry, mineral value addition and job creation on the continent.
Africa’s COP31 agenda should centre clean electrification
To achieve this, international campaigns like Electrify Now must deepen their partnership with Global South institutions. Western-centric messaging encouraging people to buy electric vehicles and install heat pumps at home must be paired with calls for robust transmission grids, decentralised mini-grids, industrial energy security and affordable clean cooking.
For this to happen, it would be great to see more African governments, businesses and civil society organisations join the Electrify Now campaign, where they can advocate for the challenges and opportunities on our continent.
Ethiopia is a great example, where a government policy to ban the importation of petrol and diesel cars has led to the country becoming a continental leader in the uptake of electric vehicles. Meanwhile, the Grand Ethiopian Renaissance Dam has seen the cost of electricity come down significantly and accounts for more than half of Ethiopia’s renewable energy generation capacity.
Türkiye says it has “final decision” at COP31 despite Australia running negotiations
The road to COP31 offers Africa a pivotal opportunity to place clean electrification at the very centre of its economic and climate agenda.
By taking ownership of this narrative, African leaders can insist that global targets deliver capital, technology sharing and infrastructure investments tailored to local needs.
Electrification is not a luxury or a secondary climate goal. Powered by renewable energy – the African sun and wind – it can be the engine of our green industrial transition. It is important for global climate architecture and Western governments to be aligned with that reality.

Fossil fuel expansion threatens COP31 hosts’ credibility, experts warn
Türkiye and Australia risk losing their credibility as hosts of this year’s COP31 UN climate summit if they keep betting on fossil fuels at home, climate policy experts have warned.
As governments are expected to continue fraught talks over how to advance the global transition away from oil, coal and gas in Antalya this November, both of the co-host countries are pursuing fossil fuel expansion at home, without a national timeline to phase out their use.
Türkiye has accelerated its rollout of wind and solar energy in recent years. But that progress has yet to make a dent in the country’s dependence on fossil fuels for power, as demand growth has outpaced the renewables build-out, new analysis by Climate Action Tracker (CAT) has found.
The share of electricity generated by burning coal and fossil gas – 56% in 2025 – has barely changed since 2019, and total fossil fuel use in the power sector, and the emissions it produces, are still rising, according to the report released on Friday.
The Turkish government has also signalled that fossil fuels will remain a central component of its energy mix and has outlined plans to expand the country’s burgeoning domestic gas production in the Black Sea.
‘Need to demonstrate seriousness’
Australia, which will chair the Antalya negotiations, relies on fossil fuels for over 60% of its electricity, with coal alone still supplying 45%. According to experts, it lacks an ambitious plan to shift away from fossil fuels at home, relying heavily on carbon offsetting to reach its climate targets.
Australia is also the world’s third-largest fossil fuel exporter and has plans to expand its coal and gas production, which is backed by significant government subsidies. It recently upset climate groups by approving an extension of the Saraji open-cut coal mine in Queensland.
Türkiye says it has “final decision” at COP31 despite Australia running negotiations
Jennifer Morgan, a senior fellow with the Fletcher School of Law and Diplomacy at Tufts University and former climate envoy for Germany, said Türkiye and Australia need to demonstrate their seriousness about their COP presidency roles by leading by example on the energy transition.
“They have made progress in renewable energy,” she told reporters this week. “But I think their credibility – and their ability to therefore bring momentum and good outcomes to the COP – will depend on their taking further action at home.”
Türkiye’s electrification homework
The co-hosts’ fossil fuel policies are being scrutinised in the run-up to the annual UN climate summit, with much riding on the signal climate diplomacy sends on the energy transition.
Türkiye has so far stopped short of putting any overt political capital behind the fossil fuel transition itself. It has instead been rallying support for a new global electrification target of 35% by 2035, seen as the centrepiece of this year’s non-negotiated Action Agenda put forward by Ankara.
COP31 president Murat Kurum said last week the push to electrify economies – through measures like electric vehicles and heat pumps – will “automatically” lead to a reduction in the use of fossil fuels.
Türkiye’s own energy plan projects the country’s electrification rate would fall short on the global target and only hit 25% by 2035, according to the CAT report, which called for a “substantial step-change” in electrification policies and the deployment of more renewable power and grid infrastructure.
Coal still dominant
CAT’s analysts also warned that, without a parallel phase-out of fossil fuels, rising electricity demand risks being met in part by coal and gas, failing to deliver the emissions reductions the electrification target is meant to achieve.
Türkiye has had some success in its clean energy build-out: the share of electricity generation from wind and solar rose to 22% in 2025, up from 12% in 2020, according to the CAT report.
But coal’s role in Türkiye’s electricity mix has also grown, in both its share and absolute terms, over the past decade. And while reliance on fossil gas has declined overall, it still plays an important role in Ankara’s energy policy, which is pushing to boost domestic gas production in the Black Sea.
Dr Niklas Höhne from the NewClimate Institute said the government could demonstrate leadership as COP31 president by building on its recent successes in increasing its renewable energy capacity and announcing targets and plans to phase out coal and gas ahead of the summit.
According to CAT, Türkiye should phase out coal by 2040 and fossil gas by 2045 at the latest to align its power sector with global efforts to limit the rise in global temperatures to 1.5C above preindustrial times.
Türkiye quiet on fossil fuel roadmap
Ümit Şahin, coordinator of climate change studies at the Istanbul Policy Center (IPM), said Türkiye’s strategy is to approach the fossil fuel debate exclusively from the “end-use point of view”.
“I don’t expect any push from the Turkish presidency to the producer countries in terms of fossil fuel production,” he told reporters.
Neither does Şahin believe the Turkish presidency will throw its political weight behind another big-ticket item for COP31: a new global roadmap to transition away from fossil fuels.
Brazil took on the responsibility to voluntarily draft this document outside of the formal negotiations as a way to break the deadlock at last year’s UN summit in Belém when governments clashed over whether to develop one.
The outgoing COP30 presidency will deliver the roadmap in early November – but it will be up to Türkiye and Australia to guide countries towards a decision on how the blueprint will be taken forward, either inside or outside the negotiations.
Leadership needed
Australia’s Chris Bowen, COP31’s president of negotiations, promised to lobby producing countries to deliver a “meaningful step forward” on the fossil fuel transition in an interview with The Guardian earlier this year. But he has been quiet on the role Australia sees for the fossil fuel transition roadmap.
Natalie Jones, senior policy advisor at the International Institute for Sustainable Development (IISD), said the COP31 co-presidents “must provide clear leadership” on this process.
“This roadmap cannot be left in a dusty drawer,” she told journalists. “Rather, it must be translated into action, with all countries identifying what elements they can adopt or develop in their own national roadmap.”
Like Türkiye, Australia has yet to produce a national blueprint for winding down coal, gas and oil. Rather than moving toward a phase-out, state and federal governments have kept expanding fossil fuel licensing over the past year, according to a new analysis published this month by Climate Analytics.
Under existing policy, both coal and gas are on track to remain in Australia’s power system as late as 2050 – a trajectory the report defines as incompatible with the 1.5C limit the country says it’s committed to.
No binding end dates for the Netherlands
Analysts are watching out for national transition roadmaps as a bellwether for governments that claim to be leaders in the global shift away from fossil fuels.


The Netherlands, which co-hosted the first fossil fuel transition conference in Santa Marta this year, published its own domestic roadmap earlier this week. The document followed through on a pledge that “leadership on transitioning away from fossil fuels must be backed by concrete action, not just ambitious words”, said a spokesperson for Stientje van Veldhoven, the Dutch minister for climate policy.
But experts criticised the plan for failing to set a binding end date for the country’s fossil fuel production and use. While targeting a rapid increase in renewables capacity, the Dutch government only commits to phasing out oil, gas and coal “in the energy and feedstock system to eventually zero, and to minimise fossil use” by 2050.
Yvo de Boer, a former Dutch diplomat and executive secretary of the UN climate body, said the Dutch roadmap falls short of what’s needed to give industry the confidence to deploy capital in support of the energy transition with greater predictability.
“Ultimately, a roadmap without deadlines is nothing more than a footpath paved with good intentions,” he added, writing on LinkedIn.
