   UN biodiversity summit COP17 opens in Yerevan as review finds world off track on nature goals and funding falls short

   The 17th UN biodiversity conference, COP17, opens Monday in Yerevan, Armenia, and runs until October 30, with nearly 200 treaty countries taking stock of progress on 23 global targets set in Montreal in 2022. A UN progress report released Thursday found fewer than half of national targets on track. Convention chief Astrid Schomaker said 'We're not moving fast enough.' Finance is the sharpest gap. Countries pledged to scale up biodiversity funding and to reform subsidies that harm nature, yet subsidy reform has gained little traction and a drop in foreign aid raises doubts over support for poor countries. Schomaker called whether enough money exists to finance those commitments the crucial question for the summit.

   Key facts

   • Current national commitments would protect only 26% of land and 12% of sea by 2030, per a UN progress report.
   • Countries raised $75 billion to $92 billion a year in 2023-2025, under half the $200 billion goal for 2030.
   • Aid to poor countries reached $19 billion in 2024, against a $20 billion target for 2025.
   • $7.3 trillion in 2023 flowed into nature-negative industries, per Guterres.
   • Wildlife populations fell an average of 73% between 1970 and 2022, per WWF's Living Planet Report.

   Commentary

   The problem is delivery rather than ambition: the targets were agreed in 2022, but the money and subsidy reform needed to reach them are not following. With aid to poor countries slipping, the summit's real test is whether new funding arrives, since the commitments already exist on paper.

   USDA rule changes effectively bar solar development from the Rural Energy for America Program

   The U.S. Department of Agriculture has issued final rules that effectively bar solar power development from the Rural Energy for America Program, known as REAP, which has long helped farmers and rural small businesses fund renewable energy projects. The rules were published October 1 and take effect October 16, following a series of changes that advocates say have made the program unusable. The Iowa Farmers Union and other plaintiffs, represented by Earthjustice, sued the USDA on September 28, arguing that earlier changes violate the REAP statute and the Administrative Procedure Act. The USDA said it will not comment on pending litigation, but in an email to Utility Dive it said farmland should feed America rather than produce solar power.

   Key facts

   • Solar or wind projects on cropland with components made in a foreign adversary country are no longer eligible for REAP funding.
   • Applicants must have energy systems operating for one year before they can be reimbursed.
   • In March 2026 the USDA paused REAP grant awards until rules were rewritten to match Trump's 2025 executive order.
   • Congress created REAP in the 2008 farm bill by combining two existing renewable energy and efficiency programs.
   • Earthjustice attorney Michael Youhana says the USDA is doing the opposite of what Congress directed.

   Commentary

   The sharpest change is the foreign-component test, which extends the restriction from solar to wind and makes supply chains, not land use, the deciding factor. Farmers with thin margins absorb the cost, and the USDA's farmland rationale looks weaker when its own rules hit operators who already paid upfront.

   UN climate panel fails to agree date for next global warming report

   The UN Intergovernmental Panel on Climate Change (IPCC) failed to agree on a publication date for its seventh assessment report at a meeting in Addis Ababa, according to French envoy Benoit Faraco, who said a few countries pressed to delay publication past 2028. Many European countries had wanted the report out in 2028 to inform a crucial review of progress on cutting planet-warming emissions. Saudi Arabia, India and China reportedly argued that a 2029 release would give developing countries more time to absorb its findings. IPCC chair Jim Skea urged nations to end the stalemate. Climate Action Network's Shreeshan Venkatesh said the group was deeply disappointed and called for talks to be reconvened as early as possible.

   Key facts

   • IPCC meeting in Addis Ababa failed to agree a date for the seventh assessment report
   • Many countries wanted the report published in 2028 for a review of emissions progress
   • Saudi Arabia, India and China reportedly favour postponing the report until 2029
   • Over 30 nations' ministers signed a letter criticising entrenched interests opposing emissions cuts
   • Climate Action Network called for the IPCC talks to be reconvened as early as possible

   Commentary

   The deadlock is less about the science than about who gets time to act on it, and the delay favours countries wary of its findings. Faraco's warning that the stalemate risks costing valuable time sits oddly with a process whose reports arrive only every five to seven years. Whether the talks resume quickly will show if the coalition of developed and developing nations can hold its ground.

   Slovenia faces loss of its last glacier amid record European heat

   Slovenia's glacier on Mount Triglav, its highest peak, completely melted by the end of a record hot, dry summer in Europe, leaving Skuta in the Kamnik-Savinje Alps as the country's only remaining glacier. Geographer Miha Pavsek of the Anton Melik Geographical Institute, which has kept records for both glaciers, said very little snow followed by a very warm summer was the tipping point. He predicted Skuta is on the same trajectory. Pavsek also warned of wider effects, as meltwater that feeds rivers such as the Drava and Mura also supplies groundwater used for drinking water.

   Key facts

   • Triglav Glacier, Slovenia's highest peak, completely melted by the end of the summer.
   • Skuta has shrunk from about 2.5 to 3 hectares to 1.5 hectares, with ice thinning to a few meters.
   • Triglav Glacier covered just over 14 hectares 80 years ago, shrinking to under one hectare later.
   • Experts predict all glaciers below 3,500 meters in Austria will disappear by 2050.
   • Mountain huts in the Slovenian Alps faced water shortages during the past two summers.

   Commentary

   The loss of Triglav was the predictable part; what matters is how little warning the decline gave, since its remnants shrank for years before vanishing. Skuta's fate follows the same pattern, so downstream water supplies now depend on snowfall that is no longer reliable. Valley residents and river users, not only mountaineers, will bear the cost.

   Experts weigh AI's environmental footprint as data centers draw scrutiny over energy, water, heat and noise

   AI's rapid growth has made its data centers a political flashpoint, and many Americans are worried about their water and energy demands, heat and noise. Their environmental impact is hard to pin down. It depends on each facility's location, power source and technology, and AI providers disclose little detailed data, so estimates are relied on. Sam Altman has said the average ChatGPT query uses about one fifteenth of a teaspoon of water, while an oft-cited statistic puts a 100-word email at about a bottle of water, and the two estimates conflict. Experts say the harms are not fixed and will depend on where data centers are built, how they are powered and how they are regulated.

   Key facts

   • Around 0.5% of world electricity was consumed by AI data centers in 2025, according to Our World in Data.
   • US data centers could consume up to 110 billion gallons a year by 2030, per UC Riverside-led scientists.
   • Ceres found data centers in seven states used about 3.4 trillion gallons of freshwater a year for power generation.
   • An Arizona State University study found Phoenix data center heat warmed downwind neighborhoods by as much as 4 degrees Fahrenheit.
   • Currently only about a fifth of e-waste is recycled, a rapidly growing waste stream as AI scales.

   Commentary

   The sharpest disagreement is not whether AI uses resources but how to count them, since per-query water claims differ wildly while the largest water figures come from electricity generation. For readers following Earth, the practical lesson is that impacts hinge on siting and power sources, so the outcome remains open and will be set by local decisions about grids, water and regulation.
