Key developments
Ocean talks
MAKING WAVES: African and Commonwealth countries issued a “call to action” to implement the High Seas Treaty at the Our Ocean Conference in Kenya this week, reported the Associated Press. The summit, which ends on 18 June, is focused on ocean issues including “climate change, biodiversity and pollution”, said the newswire. The UK government announced £13.9m in marine-related funding at the summit.
OCEAN ‘STRAIN’: Climate change, pollution, overfishing and biodiversity loss are putting oceans under “severe strain”, according to a UN report. The third “world ocean assessment” noted that conservation efforts have also “grown”, including through “nature-based solutions, ecosystem restoration and sustainable management techniques”. Meanwhile, another UN report said that fisheries and aquaculture production reached an all-time high of 235m tonnes in 2024.
OBSERVATION ISSUES: Scientists told the Guardian that the Trump administration’s plan to dismantle a key ocean-observation system run by the US would “severely degrade” the accuracy of weather forecasts around the world. Several Democratic and one Republican lawmaker pushed back against the plan to get rid of the system, reported the Associated Press.

Plant and fungi update
OFF-KILTER: Plant flowering times have “shifted significantly” over the last century, according to an AI-assisted analysis of 8m “digitised herbarium specimens” in the latest “state of the world plants and fungi” report from the Royal Botanic Gardens Kew. The report stated there have been “both advances and delays” in flowering date, with a median shift of 2.5 days per decade in either direction. The greatest variation was observed in the tropics, it added.
‘NEW ERA’: The report highlighted that Kew recently completed a digitisation of 7.4m herbarium and fungarium specimens in its collection. The ongoing digitisation of specimens around the world, alongside AI technology, could “transform understanding of biodiversity loss and climate change and pave the way to resolving these seemingly intractable crises”, it said.
EXTINCTION RISK: In its coverage of the report, the Guardian said that AI and digitalisation could help scientists document “vital” plant species “before they vanish”. About 40% of the world’s “assessed” 70,000 plant species are at risk of extinction, while a further 330,000 are yet to be analysed, according to the newspaper. The situation for fungi is “even more stark”, it reported, with 90% of an estimated 2m species still “unknown to science” and less than 1% of known species assessed for extinction risk.
News and views
- BEEF TRACKS: A “landmark” law in Colombia requiring the beef industry to prove supply chains are deforestation-free has taken effect, reported the Associated Press. The measure is part of efforts to “reverse decades of forest loss, much of it driven by the expansion of cattle ranching into previously forested areas”, noted the newswire.
- CONTINGENCY PLAN: With El Niño conditions officially confirmed as underway, the Indian government called for an “overhaul” of agricultural districts’ plans for managing the impact of below-normal rainfall on crops, reported Down to Earth. Around 150-200 districts have been identified as “most critical” based on projections, the outlet noted.
- MEATIER: Global meat supply has increased fourfold in the past six decades, according to a UN report covered by the Guardian. Agriculture’s “planet-heating emissions are forecast to rise by 7.6% over the next decade” as food production continues to grow, the newspaper said.
- TREES, NOT TARMAC: Kenya’s former chief justice, David Maraga, was among a number of protesters arrested in Nairobi for demonstrating against plans to turn 75 acres of Nairobi National Park into a car park, reported Kenya’s Daily Nation. Demonstrators were en route to deliver a petition to Kenya’s Wildlife Service when they were interrupted by anti-riot police officers, according to the newspaper.
- MANGROVES BACK, ALRIGHT: A new study covered by BBC News found that mangrove forests are “staging an unexpected comeback” globally. The broadcaster said mangroves had been “declining rapidly as they were cleared for fish farms and housing”, but the world is now “gaining more mangroves than it has been losing”.
- ‘LIMITED’ PROGRESS: Some 59% of the world’s largest financial institutions do not have a deforestation policy in place, according to the latest “forest 500” report from Global Canopy. The report – which assesses the 150 financial institutions that provide the most financing to the 500 companies with the “greatest influence” on deforestation – described finance sector progress on forest loss in 2025 as “limited”.
Spotlight
Coral reef ‘hope’
This week, Carbon Brief reports on research estimating coral reef resilience.
New research offers a sliver of “hope” that 30% of the world’s coral reefs could be “resilient” against the harmful effects of climate change.
The study, which is in the final stages of peer review and due to be published soon, identified swathes of reefs that have the best potential to withstand and recover from marine heatwaves and other stressors.
Climate change is a major threat to the survival of coral reefs. In a 2018 report, the UN’s science body warned that reefs could decline by an additional 70-90% at 1.5C of warming and as much as 99% under 2C.
The areas of potentially resilient reefs identified in the new study span almost 166,000 square kilometres – an area twice the size of Scotland.
These reefs are spread across 71 countries and 100 territories, but 61% are found in the territorial waters of just five nations – Australia, the Bahamas, Cuba, Indonesia and the Philippines.
The lead study author, Dr Kyle Zawada from Macquarie University in Australia, told Carbon Brief that the research shows the areas that could most likely “persist through climate change”. He added:
“[Coal reefs] are obviously in dire straits – but that’s not to say there are not pockets of resistance and pockets of resilience.”
Fewer than 30% of the reefs deemed to be the most climate-resilient are contained in protected or conserved areas, the study noted.
The map below shows a snapshot of the findings, highlighting the Great Barrier Reef off the north-eastern coast of Australia. The light pink areas are regular reefs, while the slightly darker pink are “climate-resilient” reefs.

Reef maps
The team, led by researchers from Macquarie University and the Wildlife Conservation Society, used the findings from more than 45,000 research surveys on corals over 1960-2025 in modelling simulations to create a map of coral cover around the world in 2020 and projections for 2050.
The modelling looked at various scenarios of future emissions and the researchers developed criteria to determine which reefs could be best positioned to survive or recover from extreme events and higher temperatures.
This specified that, for example, larger-sized reefs and those with a wide diversity of coral species tend to be more resilient than smaller areas with a lower variety of coral.
Zawada told Carbon Brief that the study does not replace real-life observations of how reefs respond to extremes. But, he added, it offers a “good guess” of areas to protect:
“It would be nice to say that there are these little reefs of hope, obviously with the massive asterisks that this doesn’t mean that these ones are out of the woods…and to sort of use that as a rallying call for us to take that hope forward and have a look at these reefs.”

As blue economy gathers pace, communities must benefit from ocean boom, activists say
As governments and institutions pledged billions for offshore wind, cleaner shipping and marine protection at last month’s Our Ocean Conference in Mombasa, countries are increasingly turning to the ocean as a source of jobs and climate action.
But civil society groups warn that the push to expand the “blue economy” may reproduce familiar inequalities unless coastal communities have a greater say in how projects are designed, financed and governed.
Neville van Rooy from The Green Connection in South Africa, which works with coastal communities who rely directly on the ocean for their livelihoods, said local people were frequently unaware of proposed developments until civil society groups alerted them.
“Communities need to be taken seriously,” van Rooy told delegates at the Mombasa conference held on the shores of the Indian Ocean.
“Just because they are often struggling does not mean they do not have a vision of development. Inclusivity needs to be at the centre and development pathways must build on communities’ own experience, including indigenous knowledge systems rooted in harmony with nature.”
Ocean investment flowing in
The value of the blue economy—the sustainable use and protection of marine resources—doubled from $1.3 trillion in 1995 to $2.6 trillion in 2020 and is projected to quadruple by 2050, according to the Organisation for Economic Co-operation and Development (OECD).
The scale of ambition in Mombasa was clear, with governments, institutions, companies and civil society groups announcing 320 commitments worth $6.4 billion.
The largest share went to sustainable blue economy projects, with 86 commitments worth $2.86 billion, followed by sustainable fisheries with $1.75 billion and ocean-climate action with $1.18 billion.
The pledges included support for ocean startups in Africa, coastal ecosystem restoration across the Indian Ocean, marine research and policy, recycling discarded fishing nets, sustainable livelihoods in Timor-Leste and planning tools for offshore wind.
Cynthia Barzuna, global deputy director of the Ocean Program at the World Resources Institute, said there are signs that blue finance and ocean planning are moving closer to coastal communities, particularly through the development of sustainable ocean plans.
In 2020, a group of 14 countries – co-led by Australia and Chile – pledged to manage their oceans sustainably, by jointly drawing up plans with coastal communities to shape how marine resources are managed and where investments should go.
“Once communities are involved in the planning, bring in their knowledge, and participate in designing, developing and implementing a sustainable ocean plan, it puts us on the right path,” Barzuna told Climate Home News on the sidelines of the conference.
Yet some of those countries – including Kenya, Australia and Mexico – have embarked on a new wave of offshore oil and gas projects, threatening key biodiversity hotspots, according to a recent report by a group of environmental NGOs.
When projects go wrong
Civil society groups say lessons need to be learnt from failed blue economy projects too.
In Kenya, a proposed coal-fired power plant at Lamu Port – a fragile coastal ecosystem and a UNESCO World Heritage site – was challenged by residents and campaigners who cited little consultation and threats to fishing, tourism, culture and public health.
In 2019, Kenya’s National Environment Tribunal revoked its environmental licence, citing inadequate public participation and flaws in the environmental assessment – a decision later upheld by the courts.
“It is not enough to say that whatever you are doing is in the name of the communities, their livelihoods and whatever else you want to improve”, but that they should be directly involved in projects from the start, said Omar Elmawi, a Kenyan climate activist and Convenor of the Africa Movement of Movements.
He said another lesson learnt was that environmental impact assessments must not only be completed, but “must be done rigorously” and that the process has to be transparent so that people feel involved and that their views are being counted.
Blue transition
Blue carbon schemes can also attract finance, but campaigners said communities that have long protected mangroves, seagrasses and salt marshes must be treated as rights-holders, not just beneficiaries. In some past projects, they said, communities were asked to provide labour, attend consultations or receive small payments, while outside developers retained control over carbon revenues and decisions over how ecosystems were managed.
Similarly, offshore wind and marine protected areas can bring climate and conservation gains, but if poorly planned, they can disrupt fishing grounds, marine species and small-scale fishers’ access to the sea, added campaigners.
Farida Aliwa, executive director of Natural Justice, said the answer was not to halt ocean-based development, but to put in place stronger safeguards before projects are approved, financed and expanded.
Aliwa said legal frameworks across Africa were evolving, with strategic litigation increasingly being used to hold governments accountable for environmental, climate and human rights impacts related to new projects.
But she warned that communities and coastal defenders still face shrinking civic space, and said any shift to renewable energy must be designed responsibly.
“As we work on alternatives, we need to ensure that renewable projects benefit communities,” she said.

AI governance debate silent on risks to nature, campaigners warn
As countries gathered in Geneva this week for the first UN dialogue on the governance of artificial intelligence, campaigners said the debate around the fast-evolving technology has overlooked the potential harm it could cause to nature and biodiversity.
Not only has nature been absent from discussions on the environmental impacts of AI data centres, which focus mainly on carbon emissions and water use, there has also been no consideration of how AI deployment by industry could gobble up more natural resources, activists warned.
Brian O’Donnell, director of the Campaign for Nature, said that while AI can help protect wildlife and forests, the broader boost it will give to economic growth poses a far bigger threat than expected benefits.
“We’ve seen over $250 billion of private capital go into AI in 2024 alone – and almost all of that is seeking an economic return, and the money follows commercial value,” he told journalists. “Extraction, industrial farming, resource logistics, and the engines that drive ever more consumption are all activities that contribute to biodiversity loss.”
The leading conservationist added that the policy documents produced by leading AI companies do not address the downstream effects of their technology for nature and biodiversity, focusing more on employment and other social issues.
Some have firms have put small sums towards projects that support conservation, he noted, but none are addressing the issue in a serious way or have included nature in the safety rules for their models.
“The living world that all of this rests upon – nature being the foundation of our economies, our societies, all life on earth – is not a primary concern in the governance of AI, as proposed by the corporates of AI,” O’Donnell said.
Positive uses steal the show
Last month, UN chief António Guterres launched an initiative to hold major AI firms accountable for their exploding environmental impacts, including carbon emissions, the amount of water and land used for data centres, and the energy they consume.
The UN boss also wants big players to commit to power all data centres with renewable energy by 2030. On Monday in Geneva, in a wide-ranging speech, he again raised his proposed “AI Environmental Transparency Initiative”. But nature has not featured in his comments on the issue.
In addition, the preliminary report of the newly formed Independent International Scientific Panel on AI – which assesses the opportunities, risks and impacts of AI – mentions environmental concerns only briefly.
The report, which examines available scientific evidence and was presented to governments at the Geneva dialogue, does not highlight any threats to nature and biodiversity but cites a study showing how AI has been used to track and reduce conflict between humans and wildlife.
O’Donnell pointed to “some really important technological uses of AI for biodiversity” such as monitoring species, forest damage and tree cover and using camera traps to see what kind of wildlife migrates in a particular area. But, he added, these get a disproportionate amount of attention compared with the threat from more rapacious resource extraction which he perceives as far greater.
By making commercial operations cheaper, quicker and more efficient, and opening access to untapped areas of land and sea, AI could drive biodiversity loss through increased over-exploitation of fish, wildlife and timber, worsening pollution and spreading invasive species on faster trade networks, he added.
Indigenous concerns
Indigenous peoples are also worried that their lands, critical mineral reserves and knowledge will be appropriated by AI and the accelerated economic development it fuels, said Hindou Oumarou Ibrahim, a leading global environmental activist and Indigenous leader from Chad.
Ibrahim, who produced a report on Indigenous peoples and AI for the UN in April, told journalists that before Indigenous peoples share their know-how on managing forests and stewarding nature, companies and governments must put in place principles to ensure this can happen in a fair way that prevents it being abused by bad actors.
Warning against ‘consumer club’ as G7 forms critical minerals alliance
Her report also points to positive ways that AI can support Indigenous culture and rights, such as tackling their lack of access to digital tools, preserving their languages and knowledge and mapping their territories to detect threats and better protect biodiversity.
Efforts such as those by the UN to shape the future of AI governance should look not only at what AI can do, but also ask who benefits and how it safeguards the planet, Ibrahim said.
“If we answer those questions together with Indigenous peoples as equal partners, we can build AI that serves humanity, protects biodiversity and help restore the balance between peoples and planet in an equitable and just way,” she added.
Policy processes lag AI development
Both O’Donnell and Ibrahim said they would lobby countries, the UN and AI firms themselves to put nature and biodiversity on the political agenda, including at the UN biodiversity summit in Armenia in October.
O’Donnell told Climate Home News that when the Global Biodiversity Framework, the world’s main treaty to protect nature, was agreed in 2022, AI was still nascent but has since exploded in terms of investment and its influence on economies.
The vote that stopped a data center: US communities query resource-hungry AI
He pointed to the mismatch between the timeline of the UN’s efforts to develop governance guidelines and the speed with which AI is being developed in the real world.
“Nature can’t be sidelined in these discussions,” he said, calling for a faster and more comprehensive response from policymakers, business and the environmental community.
“We have a very short window to embed nature both into the governance constitutions of the companies themselves and into the formal regulatory [system] going forward,” he added.

Ugandan farmers launch UK court case against East African oil pipeline
Four Ugandan farmers filed a case with London’s High Court on Tuesday, aiming to stop the East African Crude Oil Pipeline (EACOP) from starting to operate by asking the court to apply Uganda’s laws against the project’s UK-registered company.
The controversial 1,443-kilometre (897-mile) pipeline, majority-owned by French energy company TotalEnergies, aims to carry crude from Ugandan fields for export through neighbouring Tanzania. About 80% has been built so far, according to its developers.
The pipeline’s first oil exports are expected as soon as October, according to its developers, and the campaign group Avaaz, which is backing the farmers’ crowdfunded lawsuit, called it “one final chance to stop one of the worst oil pipelines on the planet”.
The claim, filed by London law firm Leigh Day, argues that EACOP Ltd’s role in developing and operating the pipeline breaches Ugandan laws that protect citizens’ right to a clean and healthy environment.
One of the claimants, Racheal Tugume, told a press conference she had been displaced from her land due to the pipeline’s construction, which she said had damaged local rivers, wildlife and ecosystems that communities depend on for their livelihoods just as erratic weather linked to climate change takes an increasing toll.
“I am very happy that there are people in countries like the UK who are listening to us, who are behind us and who have come to support us,” Tugume said, adding that she hoped the case would bring justice to communities affected by the pipeline.
Ugandan law in UK court
While the pipeline is a joint venture led by TotalEnergies, with smaller stakes owned by Ugandan, Tanzanian and Chinese national oil firms, it is operated by EACOP Ltd, a company registered to an office in London’s Canary Wharf financial district.
EACOP Ltd did not respond to a request for comment.
The claim appears to be the first attempt to have Uganda’s climate and environmental protections enforced in a foreign court, partly reflecting concerns over whether cases challenging the multibillion-dollar pipeline would get a fair trial in Uganda.
Ugandans living near new oil pipeline let down by compensation programmes
Concerns about access to a fair hearing are among the issues the court will consider when deciding if it should take on the case, said Matthew Renshaw, partner at Leigh Day.
Renshaw said that precedents including the Nigerian oil pollution case against Shell have shown that claims against British-registered companies for harms overseas can be successfully fought in UK courts.
“We are proud to represent the four brave principled individuals,” Renshaw said.
Constitutional protections
The pipeline project has already been subject to repeated lawsuits in several countries, none of which have succeeded. A climate lawsuit filed in Uganda more than a decade ago by a group of young people has yet to conclude. Another at the East African Court of Justice, brought by campaign groups against Uganda and Tanzania, was rejected on procedural grounds last November.
A separate ongoing lawsuit in TotalEnergies’ home country of France – a refiled version of an earlier failed claim – cannot stop EACOP going ahead, but it does seek damages from TotalEnergies for affected communities.
With the newly launched case, Leigh Day’s legal adviser Marc Willers said the claim draws on specific Ugandan laws in a bid to stop EACOP’s operations.
Uganda may see lower oil revenues than expected as costs rise and demand falls
These include the Ugandan constitution, a 2019 environmental law and the National Climate Change Act 2021, which gives Ugandans the right to bring a case before a court in circumstances where anyone or any entity threatens the country’s ability to mitigate climate change.
Stopping a “carbon bomb”
The pipeline, which will link Uganda’s Lake Albert oil fields to Africa’s east coast in Tanzania, has already displaced thousands of people and cuts through the Lake Victoria basin, one of East Africa’s major freshwater systems and a critical water source for around 40 million people.
According to the BankTrack non-profit, when the pipeline is at peak production, it will carry 216,000 barrels of crude oil per day and release over 33 million tonnes of carbon emissions each year. Over its full lifetime of 25 years, it is estimated to release about 379 million tonnes of greenhouse gas emissions across its value chain including construction, refining and product use.
A May 2026 report from Earth Insight also warns that the pipeline and related infrastructure could affect 158 wetlands in Uganda, 11 rivers, 44 protected areas and seven key biodiversity areas while disrupting about 2,000 square km of protected wildlife habitats.
This is why the primary focus of the UK court case is to stop the operation of the pipeline in its tracks, Leigh Day’s Willers said, calling it a “carbon bomb” that would worsen the world’s climate crisis.
Long wait for first hearing
While the purpose of the case is to stop the pipeline from launching operations, Renshaw said it could take about 12 months before the case gets a first hearing and about 18 months before it goes to trial.
Billions unlocked as Green Climate Fund agrees to spend more and save less
The farmers are, however, seeking an injunction to stop EACOP Ltd from proceeding with operations. In the event that shipments begin, the lawsuit will still seek to stop the pipeline from then on, Renshaw said.
“We will be doing what we can to expedite matters but it is possible that EACOP will have started operating the pipeline before the claim is heard. If that is the case, the claim would intend to halt operations from that point. For example, the pipeline may operate for just one year rather than 30-plus, resulting in far less harm,” he said.
