At the end of this CU the student will have acquired knowledge, skills and competences that allow him to define and explain the differences between meteorology and climatology, interpreting the basic elements for describing weather and climate (air temperature, humidity, clouds and cloudiness, precipitation, pressure, direction and wind speed). It will integrate the atmosphere into the terrestrial system, realizing its complexity and continuous interaction with the geosphere, hydrosphere and biosphere, analysing the interdisciplinary involved in the study of the planet and global environmental problems. The student will acquire knowledge about the anthropogenic action in climate change, from the pre-industrial era, analysing the past observed trends of climatic variables, as well as on future projections. The student will understand the importance of climate change for the practice of environmental engineering, in light of the expected impacts on natural and human systems.
