The year 2024 was marked by violence and elections, as conflicts escalated around the world and billions of voters went to the polls.
However, climate change still made headlines.
Thousands of peer-reviewed journal articles were published over the course of the year, helping shape online discourse around climate change.
Tracking these mentions was Altmetric, an organisation that scores research papers according to the attention they receive online.
To do this, it tracks how often published peer-reviewed research is mentioned online in news articles, as well as on blogs, Wikipedia and on social media platforms such as Facebook, Reddit, Twitter and – in a new addition for 2024 – Bluesky. (Carbon Brief explained how Altmetric’s scoring system works in this article.)
Carbon Brief has parsed the data to compile its annual list of the 25 most talked-about climate-related papers of the past year.
The infographic above highlights the most mentioned climate papers of 2024, while the article analyses the top 25 research papers in greater detail, including the diversity and country affiliation of authors.
Overall, Altmetric’s data reveals the papers which generated the most online buzz in 2024 were – for the fourth year running – associated with Covid-19, with five of the 10 most talked-about papers of the year related to the virus.
However, a number of the most-shared studies were about climate change, from how warming is impacting ocean currents, the economy and timekeeping, through to efforts aimed at mapping historical temperatures using proxy data.
A return from last year’s highs
After a blockbuster year for online mentions of climate science in 2023, last year saw a return to more typical levels.
The most widely shared climate paper of 2024 has a score of 5,414, placing it at the bottom end of the range for top climate papers over the past seven years.
By contrast, the three most talked-about climate papers of 2023 received the highest attention scores recorded across all of Carbon Brief’s annual reviews, which date back to 2015. They clocked scores of 13,886, 8,686 and 7,821.
(For Carbon Brief’s previous Altmetric articles, see the links for 2023, 2022, 2021, 2020, 2019, 2018, 2017, 2016 and 2015.)
The graph below shows how the score given to the top paper in Carbon Brief’s annual review has changed over the past 10 years.
A spokesperson for Altmetric says the falling popularity of climate papers was not due to any adjustments to its methodology, noting that its scoring system “had not changed”. They tell Carbon Brief that online mentions of papers – across all disciplines – have declined in recent years from a peak in 2020, resulting in lower average scores across the board.
The spokesperson said it was unclear why the average number of mentions had fallen since 2020, but hypothesised that several factors could be at play. This includes a surge of policy citations during the Covid-19 pandemic and changes in how people use social media – such as a decline in posts on public Facebook feeds and a spike in Twitter posts in 2021.

Later in this article, Carbon Brief looks at the rest of the top 25, and provides analysis of the most featured journals, as well as the gender diversity and country of origin of authors.
AMOC alarm
The most talked-about climate paper of 2024 is a Science Advances study that finds the Atlantic Meridional Overturning Circulation (AMOC) – a system of ocean currents that brings warm water up to Europe from the tropics and beyond – is “on route to tipping”.
The research, titled “Physics-based early warning signal shows that AMOC is on tipping course”, marks the first time that an AMOC tipping event has been identified in a cutting-edge climate model, in this case the Community Earth System Model.
The study’s Altmetric score of 5,414 shoots it to the top of Carbon Brief’s leaderboard and 1,272 points ahead of the second-placed paper.
However, as illustrated in the graph above, the research is the lowest-scoring climate paper to reach the top of the leaderboard since 2017.
The researchers from the Institute for Marine and Atmospheric Research Utrecht describe the paper’s finding as “bad news for the climate system and humanity”. They explain:
“Up until now one could think that AMOC tipping was only a theoretical concept and tipping would disappear as soon as the full climate system, with all its additional feedbacks, was considered.”
The study paints a grisly picture of the consequences of a collapse of AMOC. This includes a 10-30C drop in winter temperatures in northern Europe within a century, and a “drastic change” in rainfall patterns in the Amazon. The paper states:
“These – and many more – impacts of an AMOC collapse have been known for a long time, but thus far have not been shown in a climate model of such high quality.”
Papers exploring the stability of AMOC have dominated Carbon Brief’s climate science leaderboard in recent years, coming in fourth and second place, respectively, in 2023 and 2021.
Media coverage has been amplified by disagreement over what metrics to use to measure the strength of AMOC. Previous studies have used sea surface temperature to make projections about when the tipping point may occur.
The Science Advances paper reaches its conclusions using a new, “physics-based” early warning signal for the breakdown of the vital ocean currents based on the salinity of water in the southern Atlantic.
Overall, the study racked up 601 news mentions, with the Times, Guardian, Daily Telegraph, Associated Press and CNN all reporting on its findings. It was also featured in 39 blogs, the highest of any paper in the top 25, and was shared more than 3,866 times on Twitter.
Study author Dr René van Westen tells Carbon Brief he believes the paper owes its popularity to its alarming conclusion that AMOC is approaching a tipping point, as well as the detail it offers around the “large-scale changes” and “substantial” climate impacts such an event could trigger. He explains:
“The urgency of the situation, suggesting that we are heading toward this collapse, underscores the need for immediate action to prevent such a scenario. We believe that the combination of these far-reaching climate impacts and the risk of AMOC collapse contributed to the extensive media coverage of our study.”
Economic commitment
The second highest-scoring climate paper of 2024, published in the journal Nature, is “The economic commitment of climate change”. The study has an Altmetric score of 4,142 and clocks in at second in the 2024 rankings.
The three-person authorship team, from Germany’s Potsdam Institute for Climate Impact Research, used 40 years of data on damages from temperature and rainfall from more than 1,600 regions around the world to assess how damages could increase under a warming climate.
They estimate that the world economy is committed to an income reduction of 19% within the next 26 years, regardless of how rapidly humanity now cuts emissions. These damages are six times higher than the mitigation costs required to limit global warming to 2C in the near term, the authors say.
They also warn that climate change is likely to exacerbate existing inequalities, adding:
“The largest losses are committed at lower latitudes in regions with lower cumulative historical emissions and lower present-day income.”
The study was mentioned 55 times on Bluesky. It has also been cited by Wikipedia seven times, including in pages on climate justice and climate change mitigation.
The study’s lead author, Dr Maximilian Kotz, tells Carbon Brief:
“We think we made a helpful contribution by pushing the limits of the spatial scales, climate information and assumptions around long-term persistence which are used in these kinds of studies.”
However, he said the media coverage mainly focused on the final numbers, speculating that “part of the wide interest in the media was likely that these numbers were large”. He told Carbon Brief that, in his experience, it is “normal for the media not to pay much attention to the kind of details a researcher finds important”.
Kotz added that since his study came out, a number of other papers have been published using different approaches, but arriving at similar final numbers.
Record hot summer
Coming in third place is a Nature paper which uses temperatures reconstructed from tree rings to conclude the northern hemisphere summer of 2023 was the hottest in two millennia.
To build a picture of summer temperatures stretching back to AD1, the researchers turn to nine of the longest temperature-sensitive tree ring chronologies in North America and Europe, as well as observational data for 1901-2010.
Rest of the top 10
In fourth place, with an Altmetric score of 3,907, is a paper that assesses whether the classification system for tropical cyclone wind speed needs to be expanded to reflect storms’ growing intensity in a warming world. It was published in Proceedings of the National Academy of Sciences.
The research, “The growing inadequacy of an open-ended Saffir-Simpson hurricane-wind scale in a warming world”, says climate change has led to more intense storms, which could justify a new category on the Saffir-Simpson scale.
Introduced in the 1970s, the scale is used to communicate the risk tropical cyclone winds present to property. Events are ranked from category 1, for storms with winds of 74-95 miles per hour (mph), to category 5 for storms with a wind-speed of 157mph and above.
The study highlights how five tropical cyclones of the last nine years were so intense they could sit in a hypothetical sixth category, which could cover storms with winds of 192mph and above.
The study received more news coverage than any other in this year’s top 25, amassing 720 mentions.
In fifth and sixth place, with scores of 3,757 and 3,248, respectively, are a pair of Nature papers.
The first, “Critical transitions in the Amazon forest system”, finds that by 2050, 10-47% of the Amazon forest will be exposed to “compounding disturbances” that may trigger a tipping point, causing a shift from lush rainforest to dry savannah. Carbon Brief covered the study.
The second is a paper looking at how rising ocean temperatures are endangering the Great Barrier Reef. It cautions that without “urgent intervention” the world’s largest coral reef system is at risk of experiencing “temperatures conducive to near-annual coral bleaching” with negative consequences for biodiversity and ecosystem services.
The seventh-placed paper finds a reduction in sulphur emissions from ships – driven by cleaner fuel regulations introduced in 2020 – has led to “substantial radiative warming” that could lead to a “doubling (or more)” of the rate of warming this decade. (Carbon Brief published its own analysis of how low-sulphur shipping rules are affecting global warming in 2023.)
The Communications Earth & Environment study goes on to suggest that marine cloud brightening – a geoengineering technique where marine low clouds are “seeded” with aerosols – may be a “viable” climate solution.
Coming in eighth is a paper which finds that ice melt in Greenland and Antarctica is delaying an observed acceleration of Earth’s rotation, with consequences for global timekeeping.
The Nature paper, “A global timekeeping problem postponed by global warming”, finds the redistribution of mass on Earth as polar ice melts means timekeepers will have to remove a second from global clocks around 2029. If it were not for the acceleration in polar ice melt, this second would have been due for removal by 2026, it says.
Timekeepers are no strangers to tweaking time to adjust for the Earth’s rotation; 27 leap seconds have been added to Coordinated Universal Time (UTC) since the 1970s. However, the paper cautions the first-ever removal of a second is set to pose “an unprecedented problem” for computer network timing.
(Similarly, in 25th place is a Proceedings of the National Academy of Science paper that finds melting ice sheets and glaciers are redistributing the planet’s mass, causing days to become longer by milliseconds.)
In ninth place is a Nature Communications paper which finds that rates of glacier area shrinkage on the Juneau ice field, which straddles Alaska and British Columbia, were five times faster over 2015-19 relative to 1948-79.
Rounding out the top 10 is a Science study that uses proxy data to conclude that the Earth’s average surface temperature has varied between 11C and 36C over the past 485m years.
Retracted papers go viral
One of the most shared papers of the year looks into a CO2 “saturation hypothesis” – a popular topic among climate sceptics. The theory contends the atmosphere has reached a CO2 saturation point, which means that additional emissions of the gas will cause little or no further warming.
The paper argues “continued and improved experimental work” is needed to ascertain whether “additionally emitted carbon dioxide into the atmosphere is indeed a greenhouse gas”.
The research, entitled “Climatic consequences of the process of saturation of radiation absorption in gases”, was published by Applications in Engineering Science in March, but subsequently retracted by the editor.
In a retraction notice, Applications in Engineering Science said the rigour and quality of the peer-review process for the paper had been “investigated and confirmed to fall beneath the high standards expected”.
While the paper received just four news mentions, it was widely shared on Twitter, clocking more than 6,000 posts. With a score of 2,661, it would have been the ninth most talked-about climate paper of 2024 had it not been retracted.
UK political commentator and climate sceptic Toby Young, who was recently promoted to the UK House of Lords, shared an article promoting saturation theory in late December that references the research. As of 9 January, his Twitter post had been shared 6,500 times and viewed 128,300 times.
Controversial Covid-19 treatment and vaccination research also received significant attention in 2024, with four of the most talked-about papers of the year – of any topic – retracted by journal editors.
The studies in question – three of which relate to vaccines and one to hydroxychloroquine – would have placed first, third, fourth and sixth in Altmetric’s overall rankings, had they not been withdrawn.
A controversial paper that did make it into the top 25 without being retracted was a study in the journal Geomatics. It argues that a decrease in planetary albedo and variations in “total solar irradiance” explain “100% of the global warming trend” over 2000-23 and 83% of interannual variability in global temperatures.
The authors have previously proposed a theory that global warming is caused by atmospheric pressure – and were caught publishing their papers under pseudonyms, which were their own names spelled backwards.
With only four news mentions, most of the attention from this article came from other sources. A tweet from the study’s lead author prompted a heated discussion and generated thousands of likes and retweets. Overall, the research was mentioned on Twitter 9,599 times.
The study, which came 13th in the overall rankings with a score of 2,096, was also mentioned on 14 blogs, including a number of climate-sceptic websites.
Elsewhere in the top 25
The rest of the top 25 contains a varied mix of papers that were typically well-received by the scientific community, including research on oil and gas system emissions (15th), mortality due to tropical cyclones in the US (16th) and the latest “state of wildfires” update (22nd).
Paper number 12 finds that a “record-low planetary albedo”, mainly caused by low cloud cover in the northern mid-latitudes and tropics, may have been an important driver of the record-high global temperatures in 2023.
Published on 5 December in the journal Science, it is a relatively late entry into the annual rankings. Despite its late publication date, the study tops the charts for Bluesky mentions, gaining 376 mentions in less than one month.
A Communications Earth & Environment study, called “A recent surge in global warming is not detectable yet”, sits at number 21, with an Altmetric score of 2,018. The study uses statistical methods to search for a recent acceleration in global warming, and concludes that it is not possible to detect one.
The lead author of the study told Carbon Brief that the findings do not rule out that an acceleration might be occurring. She said that “the point of the paper is that it will take additional years of observations to detect a sustained acceleration”. However, some scientists questioned the utility of the methods used in the study, arguing there is evidence of an acceleration in warming.
At number 23 is a study in the journal Science which evaluates 1,500 climate policies that have been implemented over the past 25 years. The lead author of the study told Carbon Brief that taxes are “the only policy instrument that has been found to cause large emission reductions on their own”. The study received 30 mentions in blogs and more than 200 news mentions.
Some studies receive a lot of attention because they provoke discussion or a significant backlash, which drives up news stories and discussion on social media.
For example, the paper ranking at number 14 is a Nature Climate Change study claiming that the planet has already exceeded the 1.5C warming threshold set under the Paris Agreement.
The authors use proxy data from sea sponges in the Caribbean Sea to create a record of ocean temperatures from AD700 to the present day. They find that warming started 40 years before the IPCC’s pre-industrial baseline period began, and argue that this means “warming is 0.5C higher than [Intergovernmental Panel on Climate Change] estimates”.
However, many experts were critical, warning Carbon Brief that the framing of the study is misleading, and arguing that the finding has no bearing on the Paris Agreement 1.5C limit. One expert, who was also not involved in the study, said that “the way these findings have been communicated is flawed, and has the potential to add unnecessary confusion to public debate on climate change”.
The study received 262 news mentions, with some outlets – including the Guardian and New Scientist – highlighting the disagreements over the study’s framing.
All the final scores for the top 25 climate papers of 2024 can be found in this spreadsheet.
Top journals
Across the top 25 papers in Carbon Brief’s leaderboard this year, Nature features most frequently with seven papers. Nature is perennially high-placed in this analysis, taking first or joint first spot in Carbon Brief’s top 25 six times – 2021, 2020, 2019, 2018, 2017 and 2015.
In joint-second place this year are Science, Proceedings of the National Academy of Sciences and Communications Earth & Environment with three papers each.
Earth System Science Data has two papers, and there are seven journals that each have one paper.
Diversity of the top 25
The top 25 climate papers of 2024 cover a wide range of topics and scope. However, analysis of their authors reveals an all-too-familiar lack of diversity. Carbon Brief recorded the gender and country of affiliation for each of these authors. (The methodology used was developed by Carbon Brief for analysis presented in a special 2021 series on climate justice.)
In total, the top 25 climate papers of 2024 have 275 authors. This is fewer than in the past two years, partly due to the absence of the Lancet Countdown report, which typically has more than 100 authors.
The analysis reveals that the authors of the climate papers most featured in the media in 2024 are predominantly men from the global north.
The chart below shows the institutional affiliations of all authors in this analysis, broken down by continent – Europe, North America, Oceania, Asia, South America and Africa.
The analysis shows that 85% of authors are affiliated with institutions from the global north – defined as North America, Europe and Oceania. Meanwhile, only two authors are from Africa.
Further data analysis shows that there are also inequalities within continents. The map below shows the percentage of authors from each country in the analysis, where dark blue indicates a higher percentage. Countries that are not represented by any authors in the analysis are shown in grey.
The top-ranking countries on this map are the US and the UK, with 26% and 18% of the total authors, respectively. Germany ranks third on the list with 15% of the authors.
Meanwhile, only one-third of authors from the top 25 climate papers of 2024 are women. And only five of the 25 papers have a woman as a lead author.
The plot below shows the number of authors from each continent who are men (purple) and women (yellow).
The full spreadsheet showing the results of this data analysis can be found here. For more on the biases in climate publishing, see Carbon Brief’s article on the lack of diversity in climate-science research.

Analysis: The climate papers most featured in the media in 2024
Antarctic sea ice has recorded its third-smallest winter peak extent since satellite records began 48 years ago, new data reveals.
Provisional data from the US National Snow and Ice Data Center (NSIDC) shows that Antarctic sea ice hit its annual winter peak on 14 September, with an extent of 17.59m square kilometres (km2).
The organisation notes that the data is still preliminary, adding that “large fluctuations in extent are typical of Antarctic sea ice near the seasonal maximum”.
One expert tells Carbon Brief that it is “concerning to see these low values persisting”, but says that scientists need more time to determine whether this represents a “structural shift” in Antarctic sea ice extent.
Meanwhile, at the Earth’s other pole, Arctic sea ice reached its annual minimum on 12 September, ranking as the joint-10th lowest in the satellite record.
The NSIDC notes that the last 20 years have seen the lowest 20 Arctic sea ice extents in the satellite record.
Antarctic peak
Dr Lettie Roach, a polar climate scientist at the Alfred Wegener Institute in Germany, tells Carbon Brief that this year’s Antarctic sea ice maximum was “well below average for the season”. She warns that, “after several decades of stable or increasing winter Antarctic sea ice conditions, it is concerning to see these low values persisting”.
She adds:
“Compared with the Arctic, it’s less clear how recent changes in Antarctic sea ice are attributable to human-caused warming vs natural variability. We need more years of observations to better understand whether this is truly a structural shift.”
Dr Clare Eayrs, a postdoctoral researcher at the Korea Polar Research Institute (KOPRI), tells Carbon Brief that, since recording a “near-average February minimum” extent, Antarctic sea ice has “returned to unusually low winter coverage”.
She notes that Antarctic sea ice extent in July and August this year were the fifth and fourth lowest on record, respectively, adding that “all five of the lowest July extents have occurred since 2022 and all four of the lowest August extents since 2023”.
The chart below shows Antarctic sea ice extent in 2025 (dark blue) and 2026 (red) so far. For comparison, the chart shows decadal averages (dotted lines) as well as 2023 (mid blue), the year of the smallest winter sea-ice maximum on record.
Eayrs tells Carbon Brief that the regional pattern of Antarctic sea ice cover “changed substantially during the growth season”.
For example, she says that “in April, the Bellingshausen Sea remained almost entirely ice-free, while the neighbouring Amundsen Sea had more ice than usual”.
However, by late August, changes in atmospheric pressure and wind meant that “the Bellingshausen deficit had largely recovered, while ice was unusually scarce in the Amundsen Sea and across much of East Antarctica”.
Arctic minimum
Meanwhile, the Arctic recorded its minimum summer sea ice extent on 12 September. At 4.60m km2, this year ties with 2025, 2010 and 2008 as the 10th-lowest sea ice extent on record.
The chart below shows Arctic sea ice extent in 2025 (dark blue) and 2026 (red) so far. For comparison, the chart shows decadal averages (dotted lines) as well as 2012 (mid blue), the year of the smallest summer sea-ice minimum on record.
Roach tells Carbon Brief that although this minimum is not “record setting”, it is still “lower than any sea ice minimum before 2007”. She adds:
“Human-caused climate change has reduced Arctic sea ice cover and thickness, so the region is fundamentally different compared to a few decades ago.”
Scientists have been tracking Arctic sea ice thickness using a reanalysis produced called the Pan-Arctic Ice Ocean Modeling and Assimilation System (PIOMAS) since 1979.
In March 2026, the National Oceanographic and Atmospheric Administration (NOAA) terminated a global dataset of air pressure that scientists relied upon to produce PIOMAS, forcing both datasets to stop publishing updates.
The PIOMAS website says it will take “considerable effort and time” to find alternative data to use in their reanalysis. It adds that “we don’t yet have a good sense if that’s possible with available funds and if so, when we will be able to resume production of a new PIOMAS timeseries”.
Roach also notes that August saw record-breaking heat sweep across much of the world, explaining that high temperatures “extended into Arctic coastal regions, close to regions with substantial sea ice loss – particularly the Barents-Kara and East Siberian seas”.
Dr Zack Labe, a scientist at Climate Central, tells Carbon Brief that the absence of a new record does not mean that ice cover is becoming more “resilient”. He says:
“Local weather patterns across the Arctic play a really important role in year-to-year sea-ice extent, even as the long-term trend is clearly downward.”
Labe tells Carbon Brief that weather in the Arctic this summer was “influenced mainly by lower pressure toward the central Arctic, which brought cloudier and cooler conditions that limited surface melt and delayed the start of the melt season”.
He explains that this “was most obvious across parts of the Beaufort and Chukchi seas, where the melt season didn’t really kick off until after early July, which was more than two weeks later than normal”.
In contrast, he says, the Atlantic side of the Arctic “had a much more extreme summer”, with sea ice in the Barents Sea recording its “earliest melt-out on record”.
This was partly due to “unusually warm air and ocean temperatures”, Labe says. He notes, for example, that parts of western Siberia saw unusually persistent temperatures more than 5C above the 1981-2010 average for much of the summer, which extended out over the Kara Sea and contributed to substantial ice melt in this area”.
Labe tells Carbon Brief that, going forward, scientists need “more data and observations of other sea-ice metrics, like ice thickness, which may give us better insight into the overall condition of the ice pack, especially during years like 2026 when it is very fragmented”.
(In March 2026, Arctic sea ice reached its peak extent for this winter, clocking in as the joint-smallest in a satellite record going back almost half a century.)

‘Concerning’ low sea ice persists as Antarctic hits third-lowest winter peak
Participants at COP31 in Antalya will have a “duty” not to interfere in Türkiye’s internal affairs under the country’s hosting deal with the UN, reviving a clause dropped for last year’s climate summit in Brazil that human rights groups warn could put activists at risk.
Türkiye has faced growing criticism from human rights groups over the jailing of opposition figures, journalists and activists and imposed a blanket protest ban around July’s summit of the NATO military alliance in Ankara.
The contested provision is included in the binding agreement between the UN climate secretariat and the Turkish government that sets out responsibilities over logistical arrangements and details participants’ rights and obligations.
The document, signed in June but only made public on Wednesday, gives accredited COP31 attendees immunity from legal action over what they say, write or do in connection with the conference. Climate Home News understands that this safeguard can be applied to what takes place both inside and, in certain circumstances, outside of the UN-controlled COP “Blue Zone”. For the first time, this protection explicitly continues after the summit ends.
But participants enjoying these “privileges and immunities” also have a duty to respect Türkiye’s laws and regulations and not to interfere in its internal affairs, the agreement states. Rights groups fear its wide-ranging formulation could be used to discourage criticism of the host government.
Climate Home News understands that whether an action is covered by the immunity or infringes on the host’s internal affairs would be evaluated on a case-by-case basis, with close coordination between the country’s authorities and the UN climate change body.
A separate provision states that immunity shall be waived where the UN believes it would “impede the course of justice”.
‘Chilling effect’
Those same provisions featured in the host country agreements for COP28 in the United Arab Emirates and COP29 in Azerbaijan, both regarded as authoritarian regimes, before being dropped for COP30 in Brazil.
Ann Harrison, climate justice policy advisor at Amnesty International, said it is “extremely disappointing” that the COP31 agreement re-introduced clauses that could “hinder the ability of human rights defenders and civil society organisations to conduct their work safely”.
COP31 electrification pledge leaves out clean power commitment
She added the provisions could have a “wider chilling effect” on rights to freedom of expression and peaceful assembly, given concerns over the human rights situation in Türkiye, including laws that “have shrunk civic space” and their “abusive” implementation by authorities.
The UN climate change body declined to comment.
Rights groups have documented blanket protest bans, unlawful use of force by the police and prosecutions of journalists, human rights defenders and lawyers across Türkiye in the last year.
Arrests and protest bans
Last July, environmental activist Esra Işık was sentenced to more than two years for “resisting” a public official over what Amnesty International described as a peaceful protest against an urgent expropriation order linked to the expansion of coal mining in south-western Türkiye. She is appealing the conviction.
Ahead of a summit of the NATO alliance in the capital Ankara in July, authorities put in place a 13-day blanket ban on demonstrations, citing “national security”, and arrested over 200 people. Human Rights Watch said the crackdown showed Türkiye’s “ruthless intolerance of freedom of speech and assembly”.
Earlier this month, Turkish police detained dozens of people as part of what rights groups described as the government’s widening crackdown on LGBTQ+ activists and venues.
Questioned by media as to how he would guarantee the right to protest at COP31, Kurum said earlier in September that his team would “try to meet” any request they receive from civil society and give them “a free space to express themselves”.
“Don’t worry, thinking you will not be able to voice your opinions or really share your thoughts,” he said in an attempt to reassure campaigners, adding that he had put former deputy environment minister Mehmet Birpinar in charge of liaising with civil society.
Civic space needed
Camilla Pollera, human rights and climate change campaigner at the Center for International Environmental Law (CIEL), said meaningful participation at COP31 is fundamental to the legitimacy of climate action.
“At a climate summit, civil society participation necessarily includes being present, speaking out, scrutinising governments’ decisions and climate policies, and advocating for communities most vulnerable to climate change,” she added.
At last year’s COP30 summit, thousands of Indigenous people and climate activists peacefully marched through the Amazonian city of Belém in the first major demonstration outside the UN venue in four years. Smaller-scale demonstrations were largely confined to the “Blue Zone” at COP27 in Egypt, COP28 in the UAE and COP29 in Azerbaijan.
In two other separate incidents in Belém, members of the Munduruku tribe blocked access to the conference centre for hours, demanding an end to development projects in their ancestral land, and protesters stormed through the venue clashing with UN security officials.
The COP31 hosting agreement keeps some of the safeguards previously hailed by civil society groups. The government and the UN secretariat commit to upholding “the fundamental human rights” of all participants in the agreement’s preamble.
Under the deal, Türkiye also needs to ensure that security personnel follow “the highest ethical and professional standards and are expected to behave with integrity and respect”.

COP31 attendees told not to interfere in Türkiye’s “internal affairs”
As rising seas submerge growing swathes of land, countries that lose territory should still keep their national boundaries, sovereign rights and UN membership, according to a political declaration adopted at the UN General Assembly in New York on Thursday.
The declaration, which was championed by climate-vulnerable small island states, affirms “the presumption in favour of continued statehood” in the face of sea level rise fuelled by climate change, and urges countries to work together to assist communities affected by encroaching oceans.
Speaking at a high-level UN meeting to address the existential threats posed by sea level rise, Cabo Verde’s Prime Minister Francisco Carvalho, one of the initiative’s co-facilitators along with Australia, said the adoption of the text by consensus sends “a message of hope”.
“This declaration has a very special meaning. For us, sea level rise is neither a distant threat nor a theoretical concern,” he said, adding that rising seas put at risk key infrastructure, water resources and economic growth in small island states.
In the Pacific, sea levels have risen at twice the global rate, dramatically increasing coastal flooding events from two to 20 a year in the Republic of the Marshall Islands, and from zero to 102 events per year in American Samoa, according to the World Meteorological Organization (WMO).
Surangel Whipps Jr., president of the Pacific island of Palau, said the summit in New York represents a “moment of international solidarity”, and highlighted that small island states will remain permanent members of the UN.

UN Climate Summit: UN chief says world has tools to end fossil fuel age
At the UN Secretary-General’s climate summit in New York, countries shared their energy transition plans while Nepal and island nations advocated for more international support
Declaration recognises statehood
An advisory opinion by the world’s top maritime court, the International Tribunal on the Law of the Sea (ITLOS), first upheld in 2024 that countries do not have to shrink their maritime borders even if they lose land territory due to sea level rise. This was reiterated by the International Court of Justice in last year’s landmark ruling on the climate obligations of states.
The new declaration endorsed by all governments at the UN General Assembly stresses that sea level rise “is not a distant scenario but a real and lived experience for many”, and notes that international law must be implemented in global responses to rising seas.
UN Secretary-General António Guterres said the “milestone must now be translated into action”, adding that the declaration should encourage an “ongoing dialogue” at the “highest possible level” leading to practical outcomes. Pacific islands have proposed an international treaty on sea level rise that would provide more legal certainty.
“Those on the frontlines must be front and centre on every decision. We cannot allow countries and cultures to vanish beneath the waves,” he said. “The SOS has gone out. The world must answer.”
At regional summit, Pacific islands ask for COP31 support for clean energy and finance
Goodwin Friday, prime minister of St. Vincent and the Grenadines, said measures to protect vulnerable states will require adequate finance. “Investing in resilience now is more cost-effective than paying the far greater price for loss and damage later,” he added.
Championed by Australia’s COP31 co-presidency, Pacific islands have sought to put adaptation to sea level rise and ocean conservation at the top of the political agenda by inviting world leaders to attend the pre-COP31 summit co-hosted by Fiji and Tuvalu in October.
Tuvalu will also host the second global fossil fuel phase-out summit in April 2027, after around 60 governments met this year in Santa Marta, Colombia, to discuss ending their dependence on coal, oil and gas.
“Our coastlines, our reefs and our communities are living with the consequences of fossil fuel dependence every day, and our people have earned the right to help shape the way forward,” Lynda Tabuya, Fiji’s climate minister, said in a statement announcing details of the conference.
Ocean monitoring gets a boost in New York
Amid record-breaking marine heat and seas rising at unprecedented speed, governments in New York announced new commitments to protect the world’s ocean, as efforts to bolster marine ecosystems and coastal communities rise up the political agenda.
On Wednesday, the EU and Canada announced more funding for a new Europe-led ocean monitoring system called OceanEye, launched in the aftermath of a failed attempt by the Trump administration to dismantle the largest existing network of deep-sea observatories.
During an event at UN headquarters in New York, EU President Ursula von der Leyen and Canadian Prime Minister Mark Carney announced around $163 million in new funding for the initiative, with the EU pledging €92 million ($105m) on top of existing seed funding and Canada pledging C$82 million (US$58m) over five years.
According to an EU statement, while OceanEye will collaborate with the Global Ocean Observing System, that network “remains vulnerable to financial shortfalls and geopolitical disruptions”. A group of 30 countries from Europe, Africa and the Americas joined an international initiative in support of OceanEye, including large coastal nations like Brazil, Namibia and Mexico.
Von der Leyen said OceanEye “can make us the leading ocean data provider in a matter of years”, including by launching new satellites and installing new observatories in the deep ocean. “From outer space to the deepest ocean, our funding helps us keep watch beneath the waves,” she added.
Carney said the initiative would help protect Canada’s Arctic region with real-time monitoring operating year-round. “We can’t protect what we can’t see,” he said, also highlighting that Canada had expanded conservation of its ocean territory from 1% a decade ago to 15% now.
In New York, a group of 19 countries said they are either developing or implementing plans to sustainably manage all of their ocean territory, with 12 new nations joining the initiative. In a joint communiqué, they called on more countries to sign up ahead of COP31.
Warnings of El Niño-fuelled extreme heat
Scientists and world leaders have raised the alarm over this year’s record-breaking marine temperatures, which have persisted above historical peaks for more than 100 days as the naturally occurring El Niño phenomenon intensifies in the Pacific.
Extreme ocean heat could become a threat to coastal ecosystems and communities, experts fear. Water temperatures 1.5C above normal levels have also rapidly fuelled a strong hurricane in the Pacific in recent days.
Despite scientific calls for additional ocean conservation efforts, a report launched this week in New York warned that efforts to protect ocean ecosystems are lagging behind, with only 10% of the global ocean covered by conservation areas and just 3.5% designated as “effectively protected”.
