Key developments

US ocean actions cause alarm

DEEP-SEA BREACHES: US president Donald Trump signed an executive order “aimed at making it easier for companies to mine the deep seafloor”, including in international waters, according to National Public Radio. BBC News reported that the move “has been met by condemnation from China, which said it ‘violates’ international law”. In the South China Morning Post, two researchers at Nanjing University wrote that the order “will force China to act”, adding that Trump has “set the stage for heightened geopolitical tensions”. They concluded: “Should the US insist on unilateral mining, China, in collaboration with international partners, may implement maritime monitoring initiatives…[that] could document the environmental impact and breaches of standards.”

RISKY BUSINESS: Meanwhile, a Trump proclamation to loosen fishing regulations surrounding federally protected areas of the ocean – issued in mid-April – “poses major risks”, the Guardian reported. The Pacific Islands Heritage Marine national monument is home to the “most undisturbed coral reef within the US”, as well as “many threatened, endangered and depleted species”, the outlet added. Other experts said that the order – which purportedly aims to promote US fishing interests – “will negatively impact American fishers in the long run, leading to higher seafood prices for American consumers”.

OCEAN FUNDING FALLS: The 10th edition of the Our Ocean conference was held in Busan, South Korea, over 28-30 April, EFE Verde reported, where it was “attended by ministerial representatives from 100 different countries”. The newswire added that the conference would “serve as an impetus for participants to announce effective actions to accelerate the achievement of the goal of protecting 30% of the world’s oceans by 2030”. According to Mongabay, delegates to the conference announced funding commitments “totalling around $9.1bn”, but added that “this year’s numbers were the lowest since 2016”. The outlet noted that this edition was the first time the US “did not send an official delegation or make any pledges”.

Between tariffs and traceability

TARIFF-DRIVEN DEFORESTATION: US tariffs on Indonesian and Malaysian palm oil could drive up demand for soybean oil – a cheaper but more land-intensive option – and exacerbate deforestation, according to climate experts consulted by BusinessGreen. Elsewhere, Dialogue Earth reported on expectations that Brazil could expand its export of agricultural commodities to China, increasing the risk of deforestation in the South American country. Experts told the outlet that products such as soya, corn, beef and chicken could experience a surge in international demand. It added that Brazil captured a significant share of the Chinese soya market from the US during Trump’s first term.

BACKWARDS STEPS: Brazil’s supreme court ruled that Mato Grosso, the country’s biggest farming state, is allowed to withdraw tax incentives for signatories of the “soy moratorium” initiative, Reuters reported. The soy moratorium, a 2006 voluntary ban aimed at disincentivising soybean purchases from deforested areas of the Amazon, has been praised by conservationists for “slowing damage to the world’s largest rainforest”, the newswire said. However, farm lobbyists interested in increasing production are opposed to the agreement. The ruling needs to be ratified by a panel of supreme court justices before entering into force in January 2026.

COFFEE TRACEABILITY: The EU deforestation regulation has coffee farmers in Ethiopia “scrambling”, the New York Times reported. Under the new EU environmental regulation, which will enter into force at the end of the year, producers of major commodity crops will have to provide geolocation data to demonstrate that their products were not grown on recently deforested land. The outlet quoted the head of a coffee farmers’ cooperative, who said they need support to carry out the traceability of their products, adding that to do so is “very challenging and costly, and we don’t have any help”.

The climate uncertainties for west Africa’s fishers

This week, Carbon Brief unpacks three key takeaways from a recent report, published by the Salata Institute for Climate and Sustainability, on the sustainability of west African fisheries.

In west Africa, coastal fishing communities underpin a large proportion of the region’s economies and traditional ways of life.

Their number has only increased in recent years as a result of population growth and migration, driven by economic opportunity – even as fishers have faced declining catches.

A new report detailed the challenges facing the Gulf of Guinea’s fisherfolk amid a warming climate, as well as offering insight into what the future of the fishery could look like.

Here, Carbon Brief unpacked three key messages from the report.

1. Key fish catches have declined dramatically since the 1990s.

The report identified three major factors that have contributed to the decline of fish stocks in the Gulf of Guinea: climate-change-driven ocean warming, illegal fishing by industrial Chinese trawling ships and overfishing by fisherfolk using traditional methods.

According to the report, sea surface temperatures along the Ghanaian coast have increased at a rate of 0.011C annually since the 1960s – and could increase by another 1.6C by the end of the century under a high-emissions scenario. This warming is driving “significant geographic shifts” in the range of the species targeted by west Africa’s fisherfolk, the report said.

The report also identified other climate-driven threats to fishers, such as sea level rise, deoxygenation of ocean waters and beach erosion.

As a result of dwindling numbers, catches have fallen significantly – in some cases, by more than 50% – since the early 1990s “despite an increased number of workdays spent fishing, evidence of an underlying stock collapse”, the report warned.

Even under good fisheries management in the future, the report warned that the maximum catch potential will continue to decline due to warming.

2. Current management strategies are not sufficient to allow fish stocks to recover.

The climate pressures on the Gulf of Guinea fish stocks are compounded by overfishing from two main sources – industrial trawling ships, predominantly from China, and an increasing number of artisanal fisherfolk using improved equipment, such as outboard motors.

Ghana’s artisanal fishing fleet has grown from around 8,000 canoes in 1990 to more than 12,000 in 2022. Previous research has estimated that this fleet lands up to 70% of the small fish taken in the country. The report did not mince words:

“They clearly contribute to overfishing.”

Both Ghana and neighbouring Ivory Coast have implemented “closed seasons” during peak spawning months in an attempt to allow the fish populations to recover, but the policies “have produced disappointing results so far”, the report noted. It said:

“To be technically effective in rebuilding fish stocks, the closed seasons should have begun prior to 2016, before spawning stock biomass had been so badly harmed.”

3. Diversifying income will be key for adapting these communities to climate change.

The researchers surveyed fishing communities in Ghana, Ivory Coast and Nigeria that relied on fishing for “nearly all” of their livelihoods. Most of the individuals identified a decrease in catch over the preceding years.

A large majority of respondents answered “no” when asked if their children would be able to make a living off fishing or fishing-related activities.

The researchers then evaluated programmes in Ghana, undertaken alongside the US Agency for International Development, that were focused on helping fishing households diversify their income. The weekly earnings “were far from a full replacement for fishing income, but to a varying extent they did provide a useful supplement”, the authors wrote.

However, funding for these programmes was cancelled by the Trump administration in its attempt to dismantle USAID in early 2025. The report added:

“Finding substitute funding…will be difficult.”

News and views

CONSERVATION REFORM: The Washington Post editorial board called for “reforming” the US Endangered Species Act “to better incentivise citizens to protect the country’s precious biodiversity”, amid Trump’s attempted weakening of the landmark law. It argued for “giving landowners financial incentives to assist in conservation efforts” – similar to existing subsidy programmes from the US agriculture department. The editorial said: “The scale of the threats to biodiversity…makes it essential to expand federal conservation strategy beyond punitive measures.”

IMPORT IMBALANCE: Amid growing US-China tensions, top Chinese policymakers “said the country could do without American farm and energy imports”, according to the Financial Times. China’s state planner, Zhao Chenxin, “said domestic farm and energy production, along with imports from non-US sources, would be more than enough to satisfy demand”, the outlet reported. At the same time, the FT said, the “loss of the Chinese market would be a substantial hit for US farmers”. It added: “China has shown little appetite for negotiations and repeatedly blasted Washington’s claims of ongoing discussions as false.”

WAYWARD WHALES: Australia’s whale-watching season “started early” this year, according to the Sydney Morning Herald, which said the early migration was a “possible sign of stress from climate change”. A population of humpback whales migrates from Antarctica to Australia at the end of the southern hemisphere summer in “one of the longest migrations of any mammal”, the outlet said. The newspaper cited Dr Olaf Meynecke, a research fellow at Australia’s Griffith University, who explained that the “earlier migration was probably because record-low sea ice reduced krill numbers, making it harder for whales to find food”.

COFFEE GOES UP: The Associated Press reported that coffee prices have remained high due to drought and heat last year that impacted production in Brazil and Vietnam, the world’s largest coffee growers. US tariffs on coffee-producing countries “are expected to drive up costs for Americans”, the newswire added. Elsewhere, extreme weather conditions, such as drought and tropical cyclones, have affected major coconut-growing countries, with the Philippines’ output expected to decline by 20%, Bloomberg reported.

OFFSET OPPOSITION: Inhabitants of the Kajiado county, in Kenya, clashed over a carbon-offsetting initiative that would have set up a 40-year land lease deal, the Daily Nation reported. The project involved leasing 168,000 acres of the community’s ancestral land in return for “promis[ed] financial benefits”. Opponents of the deal said they were “misled and misinformed about the whole process”, but the community’s chair “dismissed the allegations of fraud or coercion”. The final signing of the deal was “postponed indefinitely”, as the two sides could not come to an agreement.

INCOMPLETE ACCOUNTING: Science Feedback questioned a recent study, published in Environmental Research Letters and covered in the media, that claimed agriculture is the largest greenhouse gas-emitting sector. According to climate scientists consulted by the outlet, while methane emissions from agriculture and fossil fuels are comparable, fossil fuels have a greater impact on CO2 emissions. Prof Pierre Friedlingstein, a climate scientist at the University of Exeter, told the outlet that the paper only considered gross emissions, not factoring in the carbon sequestration that occurs in agriculture.

Watch, read, listen

ATTENBOROUGH’S OCEAN: BBC News covered Sir David Attenborough’s new documentary, which chronicles the Earth’s oceans.

SIGHTING BIRDS: The New York Times chronicled a bird-watching trip to the Panama Canal, home to a thousand native and migratory birds.

WHALE SONGS: A Mongabay podcast interviewed biological oceanographer Dr John Ryan, who explained why listening to whales’ songs is important for their conservation.

FORESTS MONITORING: A short video by France24 featured the European Space Agency’s new satellite, which is aimed at monitoring the world’s forests.

New science

Research published in Nature Ecology & Evolution found that there is no “one-size-fits-all” approach to preserving biodiversity amid growing agriculture. The scientists found that neither agricultural expansion and intensification “consistently benefits biodiversity” and urged a “context-dependent balance” between the two.
Intense tropical cyclones may pose an extinction risk to organisms living on five island chains that are biodiversity hotspots, a Biological Conservation study found. The researchers tracked the trajectory and frequency of severe tropical cyclones over the last 50 years and used the IUCN red list to identify species at risk.
Another Nature Ecology and Evolution study found that implementing strategic restoration measures – such as those outlined in the EU nature restoration law – could improve the conservation status of more than 20% of endangered species and increase carbon sequestration.

Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.

This week

Bonn talks close

‘SIDE-STEPPING AND STALLING’: UN climate talks in Bonn have ended in “gridlock”, according to Climate Home News. The outlet reported on the failure to balance developing countries’ need for climate-adaptation finance with “richer nations’ desire to move forward” on emissions cuts. It added that both topics were subject to “rule 16”, meaning no agreement could be reached and work will be pushed to the COP31 summit in Turkey. Inside Climate News quoted UN climate executive secretary Simon Stiell, who said the talks had seen “side-stepping and stalling”.

JUST TRANSITION: One “glimmer of hope” came from negotiations on achieving a “just transition”, reported Euronews. The news outlet said negotiators “made headway on operationalising the Belém-Antalya mechanism”, intended to support people in the shift to a low-carbon economy. However, Politico concluded that much of the focus in Bonn had “shift[ed] to efforts outside diplomatic talks – raising questions about the future of global climate negotiations”.

‘ATTACKING SCIENCE’: Agence France-Presse reported on the EU, Switzerland and “dozens of developing nations” warning of “attacks on science” by a “small group of fossil-fuels interests” in Bonn. Table Briefings explained that “the 1.5C target is increasingly being challenged” and the role of the UN climate-science panel – the Intergovernmental Panel on Climate Change (IPCC) – in an upcoming assessment of global climate progress “remains controversial”. See Carbon Brief’s full write-up of the talks for more detail.

US-Iran deal

PRICE DROP: The US and Iran announced that they have reached an interim agreement to halt the war and reopen the strait of Hormuz, reported Bloomberg. Oil prices have fallen, as the “long-awaited deal” began the process of “eas[ing]” the global energy crisis triggered by the conflict, according to the New York Times. The Associated Press noted that high fuel prices will “likely outlast the Iran war”.

‘OIL GLUT’: The Financial Times reported that the International Energy Agency (IEA) has forecast a “glut of oil” emerging next year, if the peace deal holds. The IEA said this would allow countries to build new strategic reserves, as they “review their energy strategies and policies in response to the crisis”, according to Reuters.

‘NEW ERA’: Agence France-Presse reported that oil and gas companies have “few illusions about a return to normal for the Gulf energy industry after more than three months of blockage”. One analyst told the newswire that the war “showed the oil and gas industry that Hormuz risk is no longer just a geopolitical headline”.

Around the world

OCEAN MONITOR: The Trump administration is “abandoning its plan” to dismantle a $368m ocean monitoring system key for tracking climate change after a “bipartisan backlash on Capitol Hill”, reported the New York Times.
CORAL HAVEN: The New York Times covered preliminary research, presented at the Our Ocean Conference in Kenya, suggesting there could be three times as many “coral refugia” – where corals are relatively safe from climate change – than previously thought.
BAD CREDIT: Down to Earth reported that the first carbon credits issued under the Paris Agreement’s new Article 6.4 mechanism are “facing scrutiny over alleged links to institutions controlled by Myanmar’s military junta”.
OIL BACKTRACK: Reuters reported that oil-and-gas company Equinor has dropped a renewable-energy target and scaled back clean investments, while another Reuters story noted that Shell is selling off its offshore wind assets.

1.1 billion

The number of children facing “at least three overlapping climate hazards”, according to a new Unicef report covered by Agence France-Presse.

Captured

The more than 2m battery electric vehicles (BEVs), 1m “plug-in” hybrids (PHEVs) and 100,000 electric vans on UK roads are already saving drivers a total of around £3bn a year, according to new Carbon Brief analysis. This amounts to savings of more than £1,100 a year in fuel costs for each BEV driver in the UK. The analysis comes amid reports in UK media this week that the government is considering “watering down” its EV sales targets.

Oceans rising at UN climate talks

The state of the world’s oceans is inextricably linked to the changing climate – and many delegates at UN climate talks want to see more focus on this issue, reports Carbon Brief.

Oceans are often described as the world’s “greatest ally” against climate change – absorbing 30% of carbon dioxide (CO2) emissions and most of the heat generated by those emissions.

They are also the site of important climate solutions, such as huge offshore windfarms and the shipping industry’s transition to cleaner fuels.

At the same time, the oceans themselves present a growing danger to coastal communities and sea life due to sea level rise, marine heatwaves and ocean acidification.

These diverse issues have led to growing calls within the UN climate process for more focus on oceans. During climate negotiations this week in Bonn – known as SB64 – nations and civil society had a chance to air these views during an “ocean and climate change dialogue”.

‘Elevate action’

Oceans first entered UN climate outcomes in 2019, when the final COP25 negotiated text requested a new “dialogue” on “the ocean and climate change to consider how to strengthen mitigation and adaptation action”.

The following years saw this dialogue established as an annual event. However, the political weight of these discussions has been limited.

COP31 is being co-led by Turkey and Australia, but with Pacific islands playing a supporting role. These small islands sometimes self-identify as “large ocean states”, stressing the ocean’s centrality in their societies.

In Bonn, figures from across the presidency threw their weight behind this issue. Chris Bowen, an Australian minister and incoming COP31 “president of negotiations”, told attendees:

“Australia, Turkey and the Pacific see an important opportunity to elevate ocean-based climate action.”

Strategies and finance

The two-day dialogue in Bonn involved a series of panels, statements and breakout groups.

One of the main topics was how oceans are integrated into national climate plans under the Paris Agreement, known as “nationally determined contributions” (NDCs).

Three-quarters of the latest round of NDCs mention oceans, with conservation of “blue carbon” ecosystems the most frequently described action. (Landscapes such as mangroves can both absorb CO2 and protect coastal areas.)

Delegates also discussed alignment with the UN biodiversity process, as well as ocean finance, which currently makes up less than 1% of all climate finance.

(As discussions were taking place in Bonn, country officials also gathered in Mombasa, Kenya for the 11th Our Ocean Conference. Carbon Brief’s associate editor Giuliana Viglione attended the conference and will publish a full summary shortly.)

Developing countries were clear that many of the ocean-related actions in their NDCs would depend on receiving more financial support.

‘Political momentum’

With the backing of the COP31 presidency, delegates were hopeful about where this year’s dialogue could lead.

Charles Hamilton, an advisor for the Bahamas who spoke for the Alliance of Small Island States (AOSIS) in the dialogue, told Carbon Brief that island representatives “are not traveling thousands of miles to just talk and pat ourselves on the back”. He added:

“A dialogue that just remains a dialogue is just more talk – no action.”

Given that, he said “discussions in the dialogue must move into COP decisions and the decisions must be actioned”, noting the importance of finance.

Marina Corrêa, oceans lead at WWF-Brazil, pointed to an upcoming UN climate change Standing Committee on Finance forum as a space to ramp up pressure on ocean finance.

More broadly, she wanted to see the presidencies translate their support into a “leader-level ocean initiative” that could “mainstream” oceans across negotiations.

“We have a really interesting opportunity, in terms of political momentum,” Corrêa told Carbon Brief.

Watch, read, listen

‘HOTTER THAN HELL’: An episode of the BBC’s Rare Earth podcast titled “hotter than hell” considered the issue of extreme heat, with input from experts and “people facing up to the hottest temperatures on the planet”.

NOT BROKEN?: John Drake, a professor of ecology at the University of Georgia, wrote an essay for Aeon – also re-published as a Guardian “long read” – questioning the framing of ecosystems and climate systems “breaking down”.

ON COURSE: On his Volts podcast, US climate journalist David Roberts interviewed UK climate minister Katie White, quizzing her about whether the UK will “stay the course with its climate plans”.
