‘Cali Fund’ aiming to raise billions for nature receives first donation – of just $1,000
A major biodiversity fund – which could, in theory, generate billions of dollars annually for conservation – received its first donation of just $1,000 in November. The Cali Fund was created under the UN Convention on Biological Diversity (CBD) at the COP16 nature negotiations in Cali, Colombia, last year. On 19 November, nine months after […]

New method improves the reliability of statistical estimations
by
Let’s say an environmental scientist is studying whether exposure to air pollution is associated with lower birth weights in a particular county. They might train a machine-learning model to estimate the magnitude of this association, since machine-learning methods are especially good at learning complex relationships. Standard machine-learning methods excel at making predictions and sometimes provide […]

Q&A: Five key climate questions for China’s next ‘five-year plan’
China’s central and local governments, as well as state-owned enterprises, are busy preparing for the next five-year planning period, spanning 2026-30. The top-level 15th five-year plan, due to be published in March 2026, will shape greenhouse gas emissions in China – and globally – for the rest of this decade and beyond. The targets set under the […]

Climate Skeptics Rush to Misuse Texas v. BlackRock
Texas v. BlackRock (E.D. Tex.) (BlackRock), a case in which 11 states claim that the institutional-investor defendants colluded to profit through coordinated output reductions at coal companies they partially owned, remains in its early stages, with discovery continuing through 2027. Already however, opponents of climate-risk mitigation have rushed to extract specious theories of antitrust harm […]

Study shows promise for acid mine drainage recycling
by
Image credit: Vhahangwele Masindi A novel method for converting hazardous acid mine drainage into a valuable resource for drinking water treatment offers hope for communities living near polluted mining areas. Acid mine drainage (AMD), a toxic byproduct of mining, is notorious for contaminating rivers and groundwater with high concentrations of metals such as iron, aluminium, […]

Plastics dominate UK litter as rural and outdoor spaces emerge as pollution hotspots
by
A new study by the University of Portsmouth shows that plastic items make up more than seven in ten pieces of litter recorded across the UK, with countryside locations and public recreation areas carrying some of the heaviest burdens. The research draws on ten years of citizen science data collected between 2015 and 2024, using […]

Autonomous drifting robot survives under East Antarctic ice shelf to take first-of-its-kind measurements
by
Aerial view of the Denman Glacier (image credit: Pete Harmsen, AAD) A robotic float has been used to measure the temperature and salinity within a hitherto mysterious realm of the ocean, underneath massive floating ice shelves in East Antarctica. This kind of Argo float – a free-drifting, torpedo-shaped autonomous robot – is normally used in […]

New materials could boost the energy efficiency of microelectronics
by
MIT researchers have developed a new fabrication method that could enable the production of more energy efficient electronics by stacking multiple functional components on top of one existing circuit. In traditional circuits, logic devices that perform computation, like transistors, and memory devices that store data are built as separate components, forcing data to travel back […]

Net-zero scenario is ‘cheapest option’ for UK, says energy system operator
A scenario that meets the “net-zero by 2050” goal would be the “cheapest” option for the UK, according to modelling by the National Energy System Operator (NESO). In a new report, the organisation that manages the UK’s energy infrastructure says its “holistic transition” scenario would have the lowest cost over the next 25 years, saving […]

Analysis: What are the causes of recent record-high global temperatures?
The past three years have been exceptionally warm globally. In 2023, global temperatures reached a new high, after they significantly exceeded expectations. This record was surpassed in 2024 – the first year where average global temperatures were 1.5C above pre-industrial levels. Now, 2025 is on track to be the second- or third-warmest year on record.

Interview: How ‘mid-level bureaucrats’ are helping to shape Chinese climate policy
Local officials are often viewed as relatively weak actors in China’s governance structure, largely implementing policies issued from the central level. However, a new book – “Implementing a low-carbon future: climate leadership in Chinese cities” – argues that these officials play an important role in designing innovative and enduring climate policy. The book follows how […]
