Assessment of seismicity and risk from gas injection in the Groningen gas field Natural Hazards and Earth System Sciences DOI 10.5194/nhess-26-3443-2026 28 July 2026 Gas production from the Groningen gas field caused felt earthquakes, resulting in field closure in 2023. Despite this, earthquakes are expected to continue for years to come. This study models whether gas injection may be used to reduce earthquakes. The results suggest that, under continued zero-production scenarios, gas injection would decrease the number of earthquakes and the associated seismic risk compared to a no-injection scenario, offering a potential avenue for active mitigation.

CO2 and H2O isotope exchange and flux partitioning in Amazonia Biogeosciences DOI 10.5194/bg-23-5163-2026 28 July 2026 We used high-frequency H₂O and CO₂ isotope measurements taken in the Amazon Tall Tower Observatory (ATTO) to separate water vapour and carbon dioxide fluxes into their component processes. During midday, ~95 % of evapotranspiration came from plant transpiration. Isotopes also revealed the balance between photosynthesis and respiration, showing strong sensitivity to leaf CO₂ ratios. These results improve understanding of Amazon ecosystem function. Read more
The added value of new ground-based observations in improving China's methane emission quantification Atmospheric Measurement Techniques DOI 10.5194/amt-19-4759-2026 24 July 2026 Methane is a potent greenhouse gas, yet existing satellite and ground observations in China are too sparse to accurately quantify emissions, highlighting the need for an expanded ground network. Using Bayesian inversion and simulated annealing, we identify optimal locations for new sites. Results show that prioritizing stations in eastern and southwestern China would be most effective. Expanding the network with 50 stations could nearly double the current emission constraint capability. Read more
Europe's transport infrastructure is not ready to face climate change Natural Hazards and Earth System Sciences DOI 10.5194/nhess-26-3345-2026 22 July 2026 Climate extremes like floods, heatwaves, droughts, and wildfires are disrupting Europe’s transport. This study combines a review of past events and future projections to assess current losses and the future exposure of transport infrastructure. Exposure to extremes is projected to rise, but lower emissions can reduce it. Urgent action is needed to reduce emissions and adapt the Trans-European Transport Network to a changing climate.

From continental to street scales: climate change impacts on atmospheric composition over Europe and London Atmospheric Chemistry and Physics DOI 10.5194/acp-26-10115-2026 21 July 2026 We use innovative coupled modelling to quantify how natural emissions, chemistry, deposition and transport influence climate change responses of air pollutants from continental to urban scales across Europe. We highlight uncertainties in climate-sensitive biogenic emissions as key to future projections of ozone and fine particulate matter. High resolution modelling is essential for evaluating the benefits and trade-offs of climate change for achieving WHO air quality targets and guidelines. Read more
Brief communication: Temperature-driven shrinkage of a disappearing Himalayan glacier The Cryosphere DOI 10.5194/tc-20-4005-2026 21 July 2026 Glacier AX010 in Nepal, monitored since the 1970s, has been shrinking at an accelerating rate, mainly due to rising temperatures. Drone surveys, modeling, and reanalysis data show mass loss began in the early 1970s and intensified after 2000. While rising temperatures drive shrinkage, precipitation changes have neither accelerated nor mitigated mass loss. At the current rate, the glacier may disappear within 10–20 years. Read more
Wildfire-induced disruptions to evapotranspiration, runoff, and water-balance closure across California's water supply watersheds Hydrology and Earth System Sciences DOI 10.5194/hess-30-4367-2026 15 July 2026 Large wildfires are reshaping California’s water-supply forests. Using 40 years of satellite and river data, we found that severe fires greatly reduce vegetation water use, sometimes increasing runoff during dry years. Recovery varies widely across basins and can take many years. The work shows that wildfire can disturb the entire water budget and highlights the need to include fire effects when planning for future water resources. Read more
Heterogeneity of tropical diversity and ecosystems: reefal meiofaunas in equatorial western and eastern African islands Biogeosciences DOI 10.5194/bg-23-4873-2026 15 July 2026 Oceanic islands hold great ecological value as they support endemic biodiversity and act as steppingstones of dispersal. We investigated benthic meiofaunas from two exotic tropical archipelagoes (São Tomé-Príncipe in western Africa and Zanzibar in eastern Africa) and revealed marked heterogeneity in their diversity and biogeographic patterns. High endemicity of the São Tomé-Príncipe fauna underlines the effectiveness of dispersal barriers and urges conservation of those vulnerable ecosystems. Read more
Beyond the 100-year flood: probabilistic flood hazard assessment for King and Pierce Counties under future climate scenarios Natural Hazards and Earth System Sciences DOI 10.5194/nhess-26-3231-2026 13 July 2026 Flooding is a growing risk for communities around Puget Sound, where rising seas and changing rainfall patterns combine with rivers and tides. We used advanced computer models to simulate decades of water levels and river flows to better understand how often and how severely flooding may occur in the future. Our results show that climate change will increase both the frequency and extent of flooding, highlighting the urgent need for adaptation planning. Read more
Contrasting dynamics of lake- and marine-terminating glaciers under same climatic conditions The Cryosphere DOI 10.5194/tc-20-3827-2026 13 July 2026 We studied a unique glacier in South Greenland that ends in both a lake and the ocean. Using satellite data and field work, we found that the two glacier fronts behave very differently even under the same climate. At the lake glacier we identify a floating ice tongue and we infer little melt below water. The lake glacier experienced a sudden large breakup. Our work suggests that lake and marine glacier fronts must be treated differently in model simulations. Read more
