RT info:eu-repo/semantics/article T1 El cambio climático: sus causas y efectos medioambientales A1 Useros Fernández, José Luis A2 Ediciones Universidad de Valladolid AB limate change is now one of the biggest issues facing humanity because of its environmental effects and, above all, because its main determinant is the increase of greenhouse gases resulting from human activity. Climate, considered on an average and variability scale, and not simply specific values of temperature, wind and precipitation, is the result of the interaction of solar radiation, the Earth's orbit, latitude, atmospheric composition, ocean currents, the albedo effect and, above all, anthropogenic effects.The acceleration of climate change in recent decades, as a result of increased greenhouse gases produced by burning fossil fuels, is a social reality that poses a serious threat to different ecosystems. The increase in global temperature caused by the greenhouse effect is the cause of sealevel rise, the decline of the layers of snow and ice as well as the changing trend in rainfall. All these affect natural systems linked to ice, hydrological systems and water quality, biologi- cal sea and freshwater systems, and agricultural and forest productivity. Studying the causes of climate change and the evolution of its determinants, as the IPCC does, allows us to present general climate evolution scenarios according to demographic, tech- nological and energy consumption factors, as well as its effects both within the European Union and globally.
