The European Alps are expected to experience significant climate changes in the 21st century, including increased warming, altered precipitation patterns, and more intense extreme weather events. Warming is projected to accelerate, with temperatures rising by about 0.25°C per decade in the first half of the century and 0.36°C per decade in the second half. This warming is expected to lead to changes in the seasonality of precipitation, global radiation, and relative humidity, as well as more intense precipitation extremes and flooding. Snow cover is expected to decrease significantly below 1500–2000 m elevation, and droughts and natural hazards are likely to become more frequent. The study highlights the importance of understanding these changes for effective adaptation strategies, as they will have significant impacts on ecosystems and society. Climate projections are subject to uncertainties, and the reliability of these projections is an important consideration. The study uses a range of climate models and scenarios to assess the potential impacts of climate change on the Alpine region, emphasizing the need for robust and reliable climate information to support decision-making. The results indicate that the Alpine region will experience significant changes in temperature, precipitation, and snow cover, which will have important implications for water resources, tourism, and other sectors. The study also highlights the importance of considering the spatial and temporal variability of these changes, as well as the potential for increased droughts and natural hazards. Overall, the study provides a comprehensive overview of the expected climate changes in the Alpine region and their potential impacts on society and the environment.The European Alps are expected to experience significant climate changes in the 21st century, including increased warming, altered precipitation patterns, and more intense extreme weather events.
