“There is a growing demand for time-series data on hydropower availability at the site level, particularly to enable detailed investigation of the evolving role of hydropower in power grids. Such a dataset for both existing and potential hydropower sites, with global coverage, and incorporating future uncertainty, is still not available. Here, [the authors] present HydroSMADE (Hydropower Site-level Monthly Availability Data Ensemble) v1.0, a new open dataset that provides monthly hydropower availability for 1,593 existing and 124,333 potential sites worldwide over the period 1950–2100. The dataset is generated by using a global hydrologic model (Xanthos) with explicit representation of hydropower operations. Specifically, HydroSMADE distinguishes between storage and diversion sites, applies optimized operating rules, and incorporates site-specific characteristics such as generation capacity, maximum turbine flow, and reservoir storage. Driven by bias-corrected meteorological inputs, the site-level hydropower availability data is provided for 30 alternative future scenarios. Technical validation demonstrates consistency with reference datasets and literature across spatial scales, while highlighting improvements in representing operational differences between storage and diversion sites…”

“Extreme heat does not stop at rising temperatures. It threatens lives, disrupts essential services, and tests the resilience of our cities…
The June 2026 European heatwave raises a critical question: Are our cities prepared for the interconnected consequences of extreme heat?
Drawing on evidence from 854 European urban regions, 19 capitals, mortality surveillance systems, and transport operator records, [the author’s] study examines how extreme heat affects public health and essential urban infrastructure.
The findings reinforce an important argument: Effective disaster preparedness requires more than forecasting extreme temperatures. We must understand how climate hazards interact with population vulnerability, public health systems, and critical infrastructure.
By bringing these distinct strands of evidence into a single assessment while recognizing their methodological limitations, the study contributes to a broader understanding of climate-related disaster risk and urban resilience.
As climate extremes intensify, the challenge is not simply to predict the next heatwave, but to strengthen the systems that protect lives and sustain communities…”

“HIGHLIGHTS
• Record heat stress affected 44.9% of 854 European urban regions.
• Nighttime extremes were exceptionally rare across 19 capitals.
• France estimated 5764 preliminary excess all-cause deaths.
• Heat-induced sealant failure suspended Leipzig's tram network.
• A definition-first evidence audit prevents invalid aggregation of mortality estimates..."

“SUMMARY
• [Most States Have a Lot of Room for Improvement]
• Only eight states have dedicated hazard mitigation or disaster resilience offices, and even fewer have statutes that promote state, local, and intralocal alignment on hazard mitigation planning.
• [6 States Have Statutes Requiring State-Local Alignment on Hazard Mitigation Planning Goals]
• [8 States Have Statutes Addressing Plan Integration for Hazard Mitigation]
• [Few states have a statutory framework that will let them easily take greater responsibility for overseeing hazard mitigation planning if FEMA pulls back.]
• Planners can enhance community resilience by exceeding federal hazard mitigation minimums, working to integrate hazard mitigation into local comprehensive plans, and embracing exploratory scenario planning.
The Disaster Mitigation Act of 2000 [https://www.congress.gov/bill/106th-congress/house-bill/707] required all state and local jurisdictions to prepare and periodically update hazard mitigation plans to maintain eligibility for federal mitigation grants. Since then, state and local hazard mitigation planning has largely followed a process standardized through federal regulations and FEMA's official policy guides.
Thanks to these federal requirements, hazard mitigation is now a widely recognized functional area of planning. But are planners leading local mitigation planning efforts? Is hazard mitigation well integrated with core comprehensive or land use planning functions? Are federal requirements ensuring high-quality plans across the board? And which states are best prepared to step up if FEMA takes a step back from hazard mitigation planning?
Earlier this year, APA researchers compiled information on the statutory frameworks for land use, hazard mitigation, and climate action planning across all 50 states. [Their] analysis indicates that most states seem content to let federal agencies set the bar for state and local hazard mitigation planning. And the onus remains on planners and local officials to fill any gaps.
We don't know when or how the federal role in hazard mitigation planning will change. But planners don't have to wait for a "new normal" to act…”

[with autumn here in the northern hemisphere, I have been thinking about this - and NOT just because I want to avoid raking the leaves!! 😊 ]

“Until the middle of the 20th century, organic material was removed from the forest floor in Central Europe and used as bedding in the stables. The mixture of excrements and organic material was finally spread as fertilizer on the fields. The presented study aims at quantifying the hydrological effect of this historical extraction practise, also called litter raking, at extreme rainfall events. [The authors] measured surface runoff before and after such an intervention at four experimental plots simulating a rainfall intensity of 100 mm/h. Additionally, soil moisture has been recorded continuously on the plots with litter extraction and nearby control plots. The results of the rainfall simulation campaigns were as follows: One of the four experimental plots, which already produced a high amount of surface runoff without litter extraction, reacted with an increase of the surface runoff coefficient from 0.49 to 0.63 following this intervention. Another plot showed a slight reaction after litter extraction, with an increase of the surface runoff coefficient from 0.01 to 0.16, and on two plots there was hardly any reaction. After almost a year, the surface runoff that occurred after the intervention had already decreased again. The removal of ground vegetation and reduction of organic layers' thickness by litter raking causes faster changes in soil moisture and a more pronounced short-term response. Combining the different results of this study reveals a complex interplay of precipitation type, organic layers properties, its system status and the characteristics of the underlying mineral soil, which all together also controls the occurrence and intensity of surface runoff…”
