Climate, Wildfire, And Erosion Ensemble Foretells More Sediment In Western Usa Watersheds, Scott E. Lowe
Climate, Wildfire, And Erosion Ensemble Foretells More Sediment In Western Usa Watersheds, Scott E. Lowe

The area burned annually by wildfires is expected to increase worldwide due to climate change. Burned areas increase soil erosion rates within watersheds, which can increase sedimentation in downstream rivers and reservoirs. However, which watersheds will be impacted by future wildfires is largely unknown. Using an ensemble of climate, fire, and erosion models, we show that postfire sedimentation is projected to increase for nearly nine tenths of watersheds by >10% and for more than one third of watersheds by >100% by the 2041 to 2050 decade in the western USA. The projected increases are statistically significant for more than eight …
Global Scenarios Of Urban Density And Its Impacts On Building Energy Use Through 2050, Michail Fragkias
Global Scenarios Of Urban Density And Its Impacts On Building Energy Use Through 2050, Michail Fragkias
Economics Faculty Publications and Presentations
Although the scale of impending urbanization is well-acknowledged, we have a limited understanding of how urban forms will change and what their impact will be on building energy use. Using both top-down and bottom-up approaches and scenarios,we examine building energy use for heating and cooling. Globally, the energy use for heating and cooling by the middle of the century will be between 45 and 59 exajoules per year (corresponding to an increase of 7–40% since 2010). Most of this variability is due to the uncertainty in future urban densities of rapidly growing cities in Asia and particularly China. Dense urban …
