Document Summary

Global environmental change (gec) the set of biophysical transformations of land, oceans and atmosphere: can be caused by both natural processes (movement of tectonic plates, volcanic eruptions, tornadoes) and human activities (deforestation, burning of fossil fuels) The oceans) and places in between: time scales are also important when thinking about changes short term, medium term, long term, temporal scale is also important when interpreting data. One reason for studying gecs is that they can affect the quality of life of humans and other species. When considering gecs, it is also helpful to distinguish between cumulative or systematic gecs: systematic gecs are those that impact systems that span much of or the entire plant (e. g. the oceans or atmosphere) Our actions at a local scale, then, will have impacts globally due to air, or water in the case of the oceans, circulation patterns: cumulative gecs arise from local events and changes.
