Summary: This study assesses the impact of large-scale atmospheric and surface climatic conditions on spring freshets in major Arctic-draining rivers by analyzing historic daily discharges. Results show that climatic variations closely match the observed trends of increasing cold-season flows and earlier freshets. The study also finds that regulation may suppress the effects of climatic drivers on freshet volume but has no significant impact on peak freshet magnitude or timing measures.

Summary: The study evaluates GCMs participating in CMIP6 for their ability to simulate historical means and extremes of daily precipitation and temperature in Alberta, Canada. Results show that most models perform better in northern regions and worse in western mountainous areas. Models have better accuracy in simulating Tmax and duration compared to Tmin and frequency.

Summary: This study evaluates winter climate changes in six ecozones in Alberta, Canada, and identifies regions with elevated susceptibility to change in the future. The results show continued declines in winter duration and earlier onset of spring temperatures, as well as a shift from snow to rain in winter precipitation. The study suggests that high-precipitation extreme events may become more common due to shifts in precipitation distributions.

Summary: Canada, like other high latitude cold regions on Earth, is experiencing accelerated warming due to global climate change Arctic amplification in northern regions has led to warming two to three times greater than global average. Unprecedented warming is altering spatial and seasonal distribution of surface waters in Canada, requiring implementation of continental-scale prediction models to track hydrologic changes.

Summary: Environmental flows refer to the water amount necessary to sustain aquatic ecosystems, with considerations for quantity, timing, and quality. Current methods for determining environmental flows face challenges in the context of evolving climate, especially when dealing with non-stationarity in flow time series. More research is needed to address potential caveats associated with popular hydrological methods and to incorporate flow quality in future analyses.

Summary: The study used the degree-day Snowmelt Runoff Model (SRM) combined with MODIS to remotely sense various factors for predicting future runoff changes. The SRM simulations showed consistent patterns in historical flows and future projections, demonstrating good performance in simulating runoff.

Summary: Under 2 degrees C of global warming, the relative contribution of snowmelt and rainfall to streamflow peaks is projected to remain close to that of the current climate, despite slightly increased rainfall contribution. In contrast, a high warming scenario leads to widespread increases in rainfall contribution and the emergence of hotspots of change in currently snowmelt-dominated regions across Canada.
