UN Chief Guterres Issues Final “Moment of Truth” Climate Warning Before COP31 in Antalya

The world’s most important climate meeting opens on Monday, and the man who has spent ten years warning the planet about global warming has just delivered his bluntest message yet. United Nations Secretary-General António Guterres says the world has reached a “moment of truth” on climate change — and that the most famous climate goal of all, limiting warming to 1.5 degrees Celsius, can no longer be achieved.

In a 20-minute interview with The Associated Press from his office at UN headquarters in New York, Guterres repeated the phrase “moment of truth” three times. It was his final climate warning as UN chief: his second term ends at the close of 2026, and the COP31 climate summit in Antalya, Türkiye, which runs from 9 to 20 November, will be the last one he attends as Secretary-General.

His message was simple. The science is clear, the solutions exist, and what is missing is political leadership. “The emission gap now is a leadership gap,” he said when the UN’s latest climate report was published in October.

What Guterres actually said

Guterres told the AP that he had wanted to hold on to the goal agreed in Paris in 2015 — to keep global warming to 1.5 degrees Celsius above pre-industrial levels. But scientists told him, before a major speech last year, that the goal is no longer achievable because of the carbon dioxide and other greenhouse gases already built up in the atmosphere.

He said he was shocked by that reality. But he was clear about where the blame lies. The failure, he said, is not the world’s — it is the failure of political leaders.

He also had three words of advice for whoever succeeds him as Secretary-General: “tell the truth.” The race to replace him is already under way.

Guterres is not giving up. He said the world must now focus on making the overshoot — the amount by which warming goes past 1.5 degrees — as small and as short as possible, and then bring temperatures back down below 1.5 degrees before the end of the century. That is still possible, he believes, but only if countries change course now.

He pointed to the rapid growth of wind and solar power around the world as a reason for hope, drawing on his own experience as Prime Minister of Portugal in the late 1990s, when he argued that investing in a sustainable future was possible. But he warned that wars in Ukraine and Iran, and the huge energy demands of artificial intelligence, are adding new pressure at exactly the wrong time.

He also repeated a demand he has made before: fossil fuel companies are making huge profits from the products causing the crisis, and those profits should be taxed to help the countries hit hardest by climate change.

The 1.5°C goal is gone — what does that actually mean?

The 1.5-degree target has been the centrepiece of global climate policy since the Paris Agreement was adopted in 2015. Almost every country in the world signed up to try to keep warming “well below” 2 degrees, and to make every effort to stay within 1.5 degrees.

Why 1.5? Because scientists found that every fraction of a degree matters. At 1.5 degrees of warming, the world faces serious damage: hotter heatwaves, heavier floods, longer droughts and rising seas. At 2 degrees, all of that gets much worse, and some changes — like the loss of coral reefs and the melting of polar ice — become far harder to reverse.

Now the UN itself says the 1.5-degree limit will be passed. The UN Environment Programme’s annual Emissions Gap Report, published in October 2026, concluded that the world will no longer be able to keep warming below 1.5 degrees.

Here is what the report says needs to happen instead:

• Countries must cut carbon dioxide emissions by almost a fifth by the end of this decade, compared with 2025 levels, to keep the overshoot as small as possible.
• Even then, temperatures are likely to rise to between 1.7 and 1.8 degrees above pre-industrial levels before coming back down.
• The aim is to return to 1.5 degrees by the end of the century — but that requires deep cuts starting now, not later.

In plain terms: the world has missed its best-case target. The question now is how bad the overshoot gets, and for how long it lasts. The longer countries delay cutting emissions, the greater the danger of passing “tipping points” — thresholds after which changes like the collapse of the Amazon rainforest or the melting of Arctic ice become self-driving and irreversible.

The planet has already warmed by more than 1 degree Celsius since the late 1800s. The year 2024 was the hottest ever recorded. The UN has warned that without much stronger action, temperatures could rise by up to 3 degrees by 2100.

What is COP31, and why does Antalya matter?

COP31 is the 31st session of the Conference of the Parties to the UN Framework Convention on Climate Change — the annual summit where nearly 200 countries negotiate how to tackle global warming. This year’s meeting takes place in Antalya, a city on Türkiye’s Mediterranean coast, from 9 to 20 November 2026.

It is an unusual COP in several ways:

• Two countries are sharing the job. Türkiye holds the COP31 presidency and sets the agenda, while Australia leads the actual negotiations. It is the first COP held on Turkish soil.
• The leaders’ summit comes mid-way through. Heads of state and government gather for the Antalya Leaders Summit on 11 and 12 November. On 11 November, President Recep Tayyip Erdoğan, Australian Prime Minister Anthony Albanese and Guterres will plant trees together in a “Peace Forest” created for the summit.
• A big review begins. COP31 marks the start of the second Global Stocktake, the formal check on how far the world has come under the Paris Agreement. It covers the period from 2024 to 2028 and will conclude at COP33 in 2028.
• Money is on the table. At COP29 in Baku, developed countries agreed to mobilise at least 300 billion US dollars a year by 2035 to help developing countries deal with climate change. In Antalya, poorer nations will be asking whether that promise is being kept — and whether it is enough.

The summit’s theme is “Towards a Sustainable, Resilient and Equitable Future.” The European Union has said it will push for faster global climate action at the meeting.

The world without America at the table

One of the biggest shadows over COP31 is the absence of the United States from the negotiations. The Trump administration pulled the US out of the Paris Agreement for a second time, and the US government is not taking part in the talks in Antalya.

America is the world’s second-largest emitter of greenhouse gases, and its absence makes every negotiation harder. The US delegation in Antalya will instead come largely from Congress: a 19-member group of lawmakers led by the Sustainable Energy and Environment Coalition Institute plans to attend, meet policymakers and business leaders, and show that at least part of the American political system is still engaged.

The European Union, China and other major emitters will be watched closely to see whether they step into the gap. Guterres has repeatedly said that leadership from vulnerable developing countries cannot substitute for responsibility from developed countries — and the G20 group of major economies accounts for about 80 percent of global emissions.

What it means for Pakistan

For Pakistan, COP31 is not an abstract debate. It is about survival.

Pakistan is one of the countries most exposed to climate change, despite producing only a tiny share of global emissions. The floods of 2022, which Guterres visited and described as a climate catastrophe, drowned a third of the country at their peak and caused tens of billions of dollars in damage.

Guterres knows Pakistan well. He visited the country again in October 2026, holding a joint news conference with Foreign Minister Ishaq Dar in Islamabad, where he urged developed nations to deliver the finance and technology that vulnerable countries need to build resilience against climate shocks.

The stakes were underlined just this week by a UN warning that 90 million displaced people around the world now live in climate danger zones — areas exposed to floods, droughts, storms and rising seas. Pakistan hosts large numbers of displaced people, and its own citizens are repeatedly forced from their homes by floods and extreme heat.

What Pakistan and other developing countries want from COP31 is straightforward: money for adaptation — flood defences, early warning systems, drought-resistant farming — and money for “loss and damage”, compensation for the destruction that climate change is already causing. The 300-billion-dollar-a-year promise from Baku is a starting point, but many developing nations say it falls far short of what is needed.

The signs Guterres pointed to

Guterres did not rely on statistics alone. In the interview, he returned again and again to things he has seen with his own eyes.

Three years ago, he travelled to the highest peaks of Nepal and warned of a future of landslides and bursting glacial lakes as Himalayan ice melts. He said those disasters arrived faster than he expected. Floods in Nepal in August killed more than 1,400 people and left thousands missing, according to the UN. More than 84,000 people were affected, damage is estimated at around 2.7 billion dollars, and the cost of recovery could reach 4.7 billion dollars. Nepal and Bhutan are now pressing for more attention at COP31 to the needs of mountain countries.

He also spoke of a recent visit to a research platform in the Arctic Ocean, where scientists told him the region is warming three to four times faster than the global average, with sea ice shrinking and multi-year ice disappearing. “What’s happening in the Arctic doesn’t stay in the Arctic,” one of the scientists warned him.

And he recalled his phrase from 2023, when he declared that the era of “global boiling” had arrived — a warning that the world had moved past warming into something more dangerous.

Former US Vice President Al Gore praised Guterres for being eloquent and forceful on climate, while Laurence Tubiana, who led the negotiations that produced the Paris Agreement, said he had pushed the climate agenda further than any of his predecessors — despite working in what she called deeply hostile political conditions.

Guterres himself admitted the limits of his office. Countries are not required to follow UN orders, and the big powers hold vetoes. What the UN has, he said, is a voice — and he has used it for ten years to tell the truth about the climate crisis.

What happens next

COP31 opens formally on Monday, 9 November, at 10 in the morning in Antalya. Here is what to watch:

1. The leaders’ summit (11–12 November): Do heads of government arrive with new promises on cutting emissions and paying for climate action — or just warm words?
2. The money argument: Will developed countries show they are delivering on the 300-billion-dollar pledge, and will developing countries win a bigger commitment?
3. The US question: Can the rest of the world make progress without the world’s second-biggest emitter at the negotiating table?
4. The overshoot plan: Will countries agree on a credible path to limit how far temperatures go past 1.5 degrees — and to bring them back down?
5. Pakistan’s voice: How strongly do Pakistan and other climate-vulnerable nations press their case for adaptation finance and loss-and-damage payments?

Whatever happens in Antalya, this summit marks the end of an era. When Guterres leaves office at the end of 2026, the UN will have a new Secretary-General — and the climate fight will have a new voice. His final message to the world is the one he has repeated for a decade, and three times in a single interview: this is the moment of truth.

Frequently Asked Questions

What is COP31?

COP31 is the 31st annual UN climate change conference, where nearly 200 countries negotiate action on global warming. It takes place in Antalya, Türkiye, from 9 to 20 November 2026.

What did Guterres mean by “moment of truth”?

He means the world can no longer delay. The 1.5-degree warming limit is about to be passed, and the choices countries make now will decide how bad the overshoot is — and whether temperatures can be brought back down by the end of the century.

Is the 1.5°C target officially dead?

The UN Environment Programme says the world will no longer be able to keep warming below 1.5 degrees. The goal now is to keep the overshoot as small and as short as possible, and to return to 1.5 degrees by 2100.

Why is the US not at COP31?

The Trump administration withdrew the United States from the Paris Agreement for a second time and is not taking part in the negotiations. A 19-member delegation from the US Congress is attending instead.

What does COP31 mean for Pakistan?

Pakistan is among the countries hardest hit by climate change. It is pushing, with other developing nations, for more money for flood defences, early warning systems and compensation for climate damage already suffered.

Who will replace Guterres as UN Secretary-General?

His second term ends at the end of 2026. The race to choose his successor is already under way.

Conclusion

António Guterres has spent ten years as the world’s loudest voice on climate change. His final warning, delivered days before COP31 opens in Antalya, is his most honest: the world has failed to hold warming to 1.5 degrees, and the failure belongs to political leaders, not to science and not to ordinary people.

But his message is not one of surrender. The overshoot can still be kept small. Temperatures can still be brought back down. Wind and solar power are growing fast, and the solutions exist. What is missing is the will to use them at the speed the crisis demands.

COP31 will show whether the world heard him. For Pakistan — and for the 90 million displaced people living in climate danger zones — the answer cannot wait.
