Key developments Heatwave scorches European agriculture ‘PUSHED TO THEIR LIMITS’: The record-breaking heatwave that swept through much of western and central Europe in recent weeks had myriad impacts across the continent, reported Carbon Brief. Martin Lines, chief executive of the Nature Friendly Farming Network, explained: “Prolonged high temperatures place huge stress on livestock, dry out soils and reduce crop resilience, all while putting more pressure on nature.” The Times noted that “refrigerated warehouses were pushed to their limits” by the high temperatures. POULTRY PROBLEMS: “At least several hundred thousand poultry” perished in France due to the extreme temperatures, the head of a French poultry-industry group told Reuters. A separate Reuters article said that “cows and pigs were suffering from heat stress” in Belgium, “which has raised concerns about milk and meat production”. Meanwhile, UK government data obtained by Carbon Brief showed that “twice as many animals died due to heat stress en route to slaughterhouses” amid record heat in 2025, compared to 2024. FIRE AND ICE: The heatwave also had widespread impacts on the natural world. A wildfire scorched 200 hectares of moorland in Derbyshire, reported the Times. Derbyshire’s fire service said: “The ground is tinder dry and the slightest spark…could soon escalate to a major incident.” Agence France-Presse reported that “Swiss glaciers are set to lose an enormous amount of ice”, noting that this is the “second-earliest arrival on record of the tipping point known as ‘glacier-loss day’”. UK 2050 farm plan FARM CHANGES: The UK government launched a 2050 “farming roadmap” for England, setting out aims to make agriculture more resilient to climate change, increase domestic food production and boost nature recovery. The plan is “full of ambition”, but “falls short” on action and delivery, said National Farmers’ Union president Tom Bradshaw in a statement. Meanwhile, the government also announced £47m in funding for peatland protection and restoration schemes. FOREST LOSS: UK companies may soon be required to “check that their supply chains are free from products linked to illegal land clearances”, reported the Times. The government revived plans for anti-deforestation rules for products such as soya, palm oil, cocoa and rubber, said the newspaper. The rules will initially target goods linked to illegal deforestation, but later move to a “blanket ‘deforestation-free’ standard”, it noted, adding that similar plans in the EU have been repeatedly delayed. FRAUGHT FUND: UK energy secretary Ed Miliband was “poised to announce” a £400m commitment to the Tropical Forest Forever Facility, but the plan was “shelved over ‘optics concerns’” amid a “bitter row over defence spending”, said the Times. Meanwhile, one of Europe’s oldest and largest trees died after “becoming stressed by a series of hot, dry summers”, reported the Guardian. The Major Oak, which has grown in England’s Sherwood Forest “for at least 1,000 years”, did not produce leaves this year, said the newspaper. News and views - OCEAN ACTION: The Our Ocean Conference concluded in Mombasa, Kenya, with more than 300 voluntary commitments from governments, civil-society groups, non-governmental organisations and others, said Carbon Brief. Observers told the outlet that “these pledges must now be backed up by action”. - HOT SEAS: Record-high global ocean temperatures in June could lead the world to “uncharted territory”, said the Financial Times. Meanwhile, the Independent reported that a species of sea star thought to be extinct was found off the coast of California. - EU PLANS: The European parliament approved rules to allow the use of gene-edited plants, marking a “major shift” in the EU’s approach to modified crops, reported Bloomberg. Meanwhile, Grilled, a new investigative newsletter, said the EU is “considering an overhaul of how it measures methane emissions from livestock”. - BRAZIL BLAZES: Last year, fires caused a “significant spike in forest loss” across three areas in Brazil home to Indigenous peoples living in “voluntary isolation”, according to Mongabay. Indigenous leaders told the outlet that fire “affects their productive practices and destroys the biodiversity and vegetation they depend on”. - DISCLOSURE DISPARITY: The Biodiversity Footprint Company analysed the climate- and biodiversity-related disclosures of “120 of the world’s largest listed companies”. It found that “companies disclose roughly two-thirds of assessed climate information, yet less than one-20th of the equivalent biodiversity information”. - FRUITLESS: Fruit growers across the US south-western state of Utah “are reporting near-total harvest losses”, reported High Country News. It noted that a warm, dry winter, followed by a “record-breaking spring heatwave”, led orchards to bloom early, but the crop was then “devasta[ed]” by a “series of April freezes”. Spotlight ‘Up and running immediately’: what’s next for the High Seas Treaty This week, Carbon Brief speaks to Rebecca Hubbard, director of the High Seas Alliance, about the High Seas Treaty (also known as the agreement on the conservation and sustainable use of marine biological diversity of areas beyond national jurisdiction, or BBNJ). This interview was conducted at the Our Ocean Conference in Mombasa, Kenya. This interview has been lightly edited for clarity and length. Carbon Brief: What connects BBNJ and climate change? Rebecca Hubbard: The high seas cover half of the planet, or two-thirds of the global ocean. The ocean is essential for many things, including producing oxygen, absorbing carbon and absorbing the enormous amount of excessive heat we’ve produced as a result of burning fossil fuels. The ocean, including the high seas, cannot perform its critical climate-regulating role without healthy populations, without being healthy, and – at the moment – the high seas are not protected. In fact, only around 1% of the high seas are protected and they’re under immense pressure from shipping, fishing, pollution [and] climate change – both heating and acidification. The High Seas Treaty, for the first time ever, gives us the legal framework to be able to protect the high seas. By being able to protect and better manage the high seas, we are assuring its critical role in protecting us from the worst of climate change. CB: What were your hopes or expectations coming into this conference? RH: My hopes were that we would get strong engagement and leadership from African states in the High Seas Treaty and we have seen that, which is really fantastic. There’s been a lot of support, a lot of leadership from African governments on the treaty and on their ambitions to not just complete their ratification processes, but to also start looking at creating marine protected areas. They want to be engaged and involved in leading and delivering those processes and I think that’s really exciting. It’s a great opportunity for the whole world. We can really get some exciting collaborations. CB: What has been missing from the conversation here? RH: I actually don’t think much has been missing, because I think there’s been a lot of different conversations. There’s been conversations around the need for finance to implement the treaty and this is something that’s common across all multilateral environmental agreements – certainly no stranger to the climate process. We’re going to need this huge amount of resources to implement the treaty. Where is that money coming from? CB: We’ve got almost exactly six months until COP1 [the first Conference of the Parties for the High Seas Treaty scheduled for January 2027]. What needs to happen between now and then? RH: We need as many more countries to ratify as possible. We hope that well over 100 countries will be party to the agreement by COP1, so that they can be at the decision-making table. We need countries to really prepare for that COP, so that they’re ready to really efficiently make the decisions founded off all of the work that we’re done through the PrepCom [preparatory commission] meetings [and] so that we can get the rules of procedure and the subsidiary bodies that are going to be essential to an effective implementation up and running immediately. There is so much to do and we do not have time to waste with circular negotiations, rehashing resolved issues. We also need countries to continue to prepare for implementation, particularly back in their capitals – establishing inter-ministerial committees, so that you have a cohesive and united approach from governments that reflects a whole-of-government approach. That’s what’s going to be essential for effective implementation.

REEF RESILIENCE: In bioGraphic, journalist Claudia Geib explored the unexpected resilience of a coral reef in Miami that is home to some critically endangered species. TRUMP VS ALGAE: The Guardian Science Weekly podcast discussed the causes of algal blooms, in light of the green algae saga at the Lincoln Memorial reflecting pool in Washington DC. FRAUGHT FARMING: A century-old state law protects the water rights of just a handful of users on the Deschutes River at the expense of the region’s farmers, said Oregon Public Broadcasting.
