Impacts of idealized land cover changes on climate extremes in Europe
###RSS_DATE###
Publication date: September 2019Source: Ecological Indicators, Volume 104Author(s): Xiangping Hu, Bo Huang, Francesco CherubiniAbstractExtremes in climate and weather can pose significant challenges to economy, ecosystems and human health. Changes in land cover are one of the drivers for variability in frequency and magnitude of extreme climate at regional and local levels. In this study, a regional climate model (COSMO-CLM v4.8) is used to simulate effects in climate extremes from two different idealized land cover change scenarios in Europe. These two simulations involve abrupt...

###RSS_DATE###
Publication date: September 2019Source: Ecological Indicators, Volume 104Author(s): Tatiana E. Gámez, Lisa Benton, Schonna R. ManningAbstractProblems associated with eutrophication are increasing in freshwater reservoirs worldwide due to many factors, the majority of which are attributed directly to human development. Eutrophic bodies of water are much more susceptible to algal blooms, including potentially harmful species, as well as associated taste-and-odor compounds and toxic secondary metabolites. To assess the likelihood of eutrophication and harmful blooms, two reservoirs in the...
