Identification of maladaptive behavioural patterns in response to extreme weather events.

Human behaviour has gained recognition as a critical factor in addressing climate change and its impacts. With extreme weather events posing risks to vulnerable communities, understanding cognitive processes driving behaviours becomes essential for effective risk communication. This study focuses on the 2018 "Vaia" storm, which brought unprecedented precipitation and wind velocity to the mountainous regions of North-eastern Italy.

The impact of glacier shrinkage on energy production from hydropower-solar complementarity in alpine river basins.

Variable energy sources such as solar and runoff sources are intermittent in time and space, following their driving hydro-meteorological processes. Recent research has shown that in mountainous areas the combination of solar and hydropower has large potential (termed complementarity) to cover the temporal variability of the energy load and, by this mean, to facilitate integration of renewables into the electricity network. Climate change is causing widespread glacier retreat, and much attention is devoted to negative impacts such as diminishing water resources and shifts in runoff seasonality.

Changing climate both increases and decreases European river floods.

Climate change has led to concerns about increasing river floods resulting from the greater water-holding capacity of a warmer atmosphere. These concerns are reinforced by evidence of increasing economic losses associated with flooding in many parts of the world, including Europe. Any changes in river floods would have lasting implications for the design of flood protection measures and flood risk zoning.

Changing climate shifts timing of European floods.

A warming climate is expected to have an impact on the magnitude and timing of river floods; however, no consistent large-scale climate change signal in observed flood magnitudes has been identified so far. We analyzed the timing of river floods in Europe over the past five decades, using a pan-European database from 4262 observational hydrometric stations, and found clear patterns of change in flood timing. Warmer temperatures have led to earlier spring snowmelt floods throughout northeastern Europe; delayed winter storms associated with polar warming have led to later winter floods around the North Sea and some sectors of the Mediterranean coast; and earlier soil moisture maxima have led to earlier winter floods in western Europe.
