“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..."
