This week

EU passes nature law

NATURE LAW: On Tuesday, the European parliament approved its “flagship” law to restore nature, reported Reuters, despite a backlash “ignited” by protests from farmers across Europe in recent weeks. The long-awaited “nature restoration” law commits countries to restoring nature on a fifth of their land and sea by 2030, the newswire said, and it includes specific targets such as restoring peatlands “so they can absorb CO2 emissions”. Carbon Brief published a Q&A unpacking the law and the challenges it has faced.

‘POPULISM AND FEAR-MONGERING’: The vote was subject to a “last-ditch attempt from rightwing parties” that “threatened to sink the deal”, reported the Guardian. The law – which now needs final approval from the EU council – was adopted with 329 votes in favour, 275 against and 24 abstentions, reported Deutsche Welle.

‘MANURE, BURNING TYRES AND TEARGAS’: The vote came amid a backdrop of continuing demonstrations by farmers across Europe, protesting against “the EU’s green policies, price pressures and import competition”, reported Politico. On Monday, farmers “locked down” the European quarter in Brussels and were “assaulting police barricades”, the outlet said. Elsewhere, Reuters reported that farmers “blocked a border crossing between Poland and Germany”.

UN environment assembly resolutions

TRANSITIONAL METALS: At the UN environment assembly in Nairobi, which comes to a close today, African leaders called for better controls on demands for the minerals and metals needed for a clean energy transition, the Guardian reported. A resolution supported by mainly African countries including Senegal, Burkina Faso, Cameroon and Chad would “promote equitable benefit-sharing” and attempt to avoid the “injustices” associated with fossil fuel extraction, the outlet explained. A UN press release confirmed that the resolution text was adopted.

SRM NO-GO: Also at the meeting, governments failed to agree on a resolution led by Switzerland to set up a UN expert panel on solar geoengineering, reported Climate Home News. After going through six revisions over the two-week meeting, the resolution was withdrawn on Thursday, said Reuters. The Earth Negotiations Bulletin reported earlier in the week that the resolution “was moving from the realm of the achievable”.

‘BALANCE’ WITH NATURE: At an event during the assembly, leading Islamic scholars published a “groundbreaking” document described as a “Muslim sibling” to Pope Francis’ 2015 Papal Encyclical, reported EarthBeat. The text, titled “Al-Mizan: a covenant for the Earth”,  urges Islamic countries and corporations “to transition swiftly from fossil fuels” toward renewable energy in response to climate change, the outlet said.

Around the world

  • WINTER WORRY: A “historic” winter heatwave across the central US “demolished” temperature records and contributed to “massive wildfires” in Texas, the Washington Post reported. One of the fires is now the second-largest wildfire in US history, noted BBC News.
  • ‘SERIOUS CONCERNS’: The UK’s aid spending watchdog has warned that the government will struggle to meet its commitment to spend £11.6bn over five years up to 2025-26 helping poorer countries deal with climate change, according to the Press Association.
  • INDIAN INSTALLATIONS: India’s solar and wind deployment is set to increase by more than 30% in 2024, reported Bloomberg, but this pace is “still not fast enough to meet its clean energy goal of 500 gigawatts by the end of this decade”.
  • US ENERGY ACCESS: The US government announced a $366m plan to fund 17 projects to expand access to renewable energy on Native American reservations and in other rural areas, said the Associated Press.
  • ‘SUSPECTED SABOTAGE’: Denmark is closing its inquiry into the blasts that “tore apart” two Nord Stream gas pipelines in the Baltic Sea in 2022, BBC News reported. The investigation concluded that the pipelines had been “sabotaged”, but there was “no basis for pursuing a criminal case”.

40,000 tonnes

The amount of wood from old-growth forests in Canada burned by North Yorkshire’s Drax power station in 2023, according to a BBC News Panorama investigation. Drax responded by denying it takes wood from primary forests.


Latest climate research

  • A four-year farm trial has shown how using “enhanced weathering” in the corn belt of the US could draw down carbon dioxide and raise crop yields, reported a study in the Proceedings of the National Academy of Sciences.
  • A Plos Climate study of apes across 363 sites in Africa warned that they “are and will be increasingly exposed to climate change impacts”.
  • A Journal of Climate study identified a “remarkable” increase over six decades in Europe’s summer wet-bulb temperature – a “useful indicator” for heat stress.

UK emissions could rise by 15% if government uses 'surplus' to weaken target

This week, the Climate Change Committee (CCC) – the UK’s official advisor – issued “unequivocal” advice to the government that the “surplus” from previous carbon budgets should not be carried forward, reported Carbon Brief. The UK overachieved on its carbon budget for 2018-22, leaving it with an emissions “surplus” – but this was largely down to external factors such as the Covid-19 pandemic rather than policies, the CCC said. It warned that carrying the emissions surplus over could allow the UK’s emissions to rise by 15% (red line on the chart) during the fourth carbon budget period of 2023-27.

Guest post: The climate ‘memory loss’ of melting glaciers

Dr Andrea Spolaor from the Institute of Polar Sciences of the National Research Council of Italy.

Dr Andrea Spolaor from the Institute of Polar Sciences of the National Research Council of Italy, explains how rapidly melting glaciers are washing away crucial evidence of the world’s past climates.

Ice cores, extracted from glaciers and polar ice sheets, hold vital clues to Earth’s climate history. 

These cylindrical samples provide a timeline of past temperatures and ancient atmospheres. Analysing the chemical composition, gas concentrations and other markers within the ice layers enables scientists to uncover how Earth and its climate has changed over millions of years.

As a result, ice cores are essential for understanding natural climate variability and human-induced changes, as well as helping predict future trends. They contribute crucial data to climate models and efforts to address climate change.

However, as the world warms, glaciers are retreating at an unprecedented pace, leading to the loss of the crucial information they hold.

In a recent study, published in the Cryosphere, my colleagues and I found that this memory loss extends to the glaciers of the Svalbard archipelago, located in the Arctic Circle. 

Our study investigated the impact of rising temperatures on the “signal” of a changing climate contained within the glaciers of the Holtedahlfonna ice field.

The direct consequence of warming has been an increase in summer melt and more meltwater percolating through the ice. This meltwater can wash chemical constituents throughout the layers of ice, potentially disrupting the climate signal they preserve. Eventually, this can compromise the complete preservation of climatic information within the ice cores.

Our study revealed a worrying trend – the climate signal stored in the ice had deteriorated. In just seven years, the markers that allowed us to separate out the different seasons in a core extracted in 2012 had completely vanished in a core from 2019.

Despite the loss of the seasonal signal, the overall imprint of atmospheric warming still persists in the ice. This suggests that the site remains suitable for reconstructing past climates over an extended period. However, with the current pace of warming in the Svalbard archipelago, Holtedahlfonna and other ice fields at similar altitudes may not provide reliable records of past climatic conditions for much longer.

The Svalbard archipelago is particularly sensitive to climate changes due to the relatively low altitude of its main ice caps and the rapid warming of the Arctic region. Nonetheless, similar losses have also been observed in other parts of the world. 

To preserve these archives, researchers involved in the Ice Memory and Sentinel projects concluded a complex ice drilling campaign in 2023 on the Holthedalfonna glacier, successfully extracting three deep ice cores. We hope that these samples still contain climatic information representative of the region. 

Our research has emphasised the need to preserve these glacial archives and the crucial climatic insights they contain.

IPCC scientists vow to press on with climate reports despite political deadlock

Published

on

Scientists have vowed to keep working on the next flagship set of reports for the Intergovernmental Panel on Climate Change (IPCC), after a political row over the timeline for their release saw its latest session suspended on Friday evening without agreement.

During the weekend, government officials and scientists alike expressed disappointment over the inability to reach a compromise before some delegates from developing countries and small island states had to leave the week-long meeting in Ethiopia to catch flights home.

The disagreement – which has persisted since early 2024 – turns on whether the three key parts of the AR7 assessment should all be published before the conclusion of the UN’s next Global Stocktake of global climate action, which is due to be completed in late 2028.

The IPCC issued a statement after the close of the session, saying that “key agenda items” – the timelines for the three AR7 reports, as well as the IPCC budget – remain open and under discussion. It said the IPCC’s plenary session and its deliberations on the pending agenda “will resume at the earliest opportunity”, giving no further details of when.

IPCC Chair Jim Skea told delegates in closing remarks that recent months had been some of the most turbulent for the climate science panel and that, if there were stronger words than “profound disappointment” he would use them, according to a summary published by the Earth Negotiators Bulletin (ENB). IPCC discussions happen behind closed doors.

IPCC scientists remained committed

In an open letter, issued on Monday, a group of nearly 120 scientists – from a total of 664 AR7 authors – said they “stand committed to continue working to deliver the AR7 reports in a manner that is rigorous, timely and inclusive, in line with our mandate to be policy-relevant”.

“An assessment that arrives after the decisions it is meant to inform cannot serve its purpose,” they emphasised. “The second Global Stocktake in 2028 is such a decision point, and the world should not have to face it without the IPCCʼs latest assessment.”

Europe, small islands and the least developed countries, plus many Latin American and developed nations, want the IPCC to meet this deadline, arguing that the findings from the UN climate science body are irreplaceable in the UN climate policy-making process.

However, around a dozen developing countries plus Russia have argued that the reports should come later in order to allow for greater research input from the Global South – something that, in their view, would make the findings fairer. They also claim that a shorter timeline would put excessive pressure on experts.

    The most vocal of this group at last week’s meeting were India and Saudi Arabia, according to the ENB summary and a developed country diplomat. Critics see this push for a longer timeline as an excuse to deprive government decision-makers of the latest science and ease pressure on emerging economies to raise their ambition, particularly on cutting emissions.

    Commenting on last week’s meeting, France’s ambassador for climate negotiations Benoît Faraco said a broad coalition of developed and developing countries from all five continents, “united in their support for science and the timeline proposed by scientists”, had withstood pressure “from a few countries” seeking to slow down the process of adopting the IPCC reports.

    He added that France would not back down and would “continue to fight tirelessly for science, protect the integrity of information, and convince our partners that without the best available scientific data, we will be less effective in tackling climate change and protecting our populations”.

    Inclusivity proposal stalled

    In a bid to unlock a solution for the AR7 timeline, countries discussed ways to improve the inclusivity of the IPCC’s work. One option put on the table was for the IPCC to expand its funding for delegates from developing countries to attend some or all of its sessions from one to two participants, according to the ENB summary and a delegate speaking to Climate Home News.

    That would increase the costs for the IPCC to complete AR7 by up to a quarter, according to an assessment shared by the secretariat. The panel’s budget is under severe strain and its officials have warned that, without additional voluntary contributions, it risks running out of money before it can deliver on this assessment cycle.

    Climate Home News understands that some of the IPCC’s traditional donors – which mainly include European countries, Japan and Australia – indicated a willingness to support funding for an additional developing country participant. But without an agreement over the budget or the timeline for the reports, that option was ultimately not adopted.

    ‘Disappointed and worried’

    The three reports are managed by working groups that collate and draw overall findings from the latest scientific studies and data on the physical effects of global warming around the world, how to adapt to it, and pathways for cutting planet-heating emissions in order to meet the temperature goals of the Paris Agreement.

    Winston Chow, an urban climate professor at Singapore Management University who co-chairs Working Group II on adaptation, wrote in a LinkedIn post that he was “disappointed and worried” for the IPCC authors who have worked “extraordinarily hard” to assess the relevant climate science over the past two years.

    He said he shared their concern that “the rigour, time and goodwill they’ve invested are now being put at risk by the Panel’s stalemate”.

    As science comes under attack at UN talks, climate movement splits over how to respond

    For Working Group II, a meeting for 250 experts writing that report is scheduled for January 2027, followed by the approval of a special report on cities and climate change in Singapore next March.

    But because the IPCC’s budget has not been confirmed due to uncertainty about the AR7 schedule, travel support for those researchers is at risk, wrote Chow. “If they cannot participate, our assessments will lose vital expertise, perspectives and scientific breadth, and the collective effort of our authors will be undermined,” he warned.

    Scientific work continues

    Despite the political holdups, he – together with French climate scientist Robert Vautard, co-chair of Working Group 1 – agreed with IPCC head Skea who told the IPCC’s closing session on Friday: “The engine room of the IPCC is working, and it’s healthy.”

    Vautard commented in a separate post on LinkedIn after it ended: “The boat is at full steam.” Working groups I and II are due to start revising the first drafts of their reports, while Working Group III on reducing emissions is finalising its first draft which will be out soon, he wrote.

    “The most exciting two years of the cycle are ahead, for the authors. The momentum in the engine room is here and now. Trust the engine room!” he added.

    The IPCC and some scientists report that progress has been made towards achieving an equitable balance of authors from the Global North and the Global South.

    The group of researchers who signed the open letter on Monday noted that “inclusivity is at the heart of how we work”, with author teams bringing together experts from developed and developing countries with diverse backgrounds and at different stages of their careers.

    Plea to overcome political differences

    The signatories include several scientists from some of the countries opposed to the alignment of all IPCC reports with the Global Stocktake.

    “We are committed to an assessment in which the knowledge, experience and priorities of every region are fully reflected, a commitment we share with the leadership of the IPCC.

    Equity is built into how our assessment is being drafted,” they added.

    They appealed to governments that make up the IPCC “to overcome their political differences and work together as we do as a global scientific community, so that we can deliver the IPCC reports the world needs to hear”.

    In a statement published on Monday, IPCC chair Skea said reaching consensus on the schedule for the reports is “vital”. He added that the assessments provide authoritative scientific evidence to inform national climate policies, strengthen adaptation and resilience and support access to climate finance, as well as helping communicate the scale of the climate crisis and the urgency of efforts to tackle it.
