a transformation that occurs on a worldwide scale (e.g., an increase in carbon dioxide in the atmosphere) or exhibits sufficient cumulative effects to have worldwide impact (e.g., local species extinction resulting in global loss of biodiversity).
a transformation which occurs on a worldwide scale (for example, an increase in CO2 in the atmosphere) or exhibits sufficient cumulative effects to have worldwide impact (for example, local species extinction resulting in global loss of biodiversity)
Changes in the global environment (including alterations in climate, land productivity, oceans or other water resources, atmospheric chemistry, and ecological systems) that may alter the capacity of the Earth to sustain life (from the Global Change Research Act of 1990, PL 101-606).
A change in climate that has worldwide effects on the environment, life, and other components of Earth.
The full range of natural and human-induced changes in Earth's environment, including alterations in climate, land productivity, oceans or other water resources, atmospheric chemistry, and ecological systems, that may alter the capacity of Earth to sustain life.
refers to change to the Earth system which is either a global phenomenon or that occurs regionally, but strongly enough and often enough to be of global significance. The leading current global change issues include climate change due to an enhanced greenhouse effect, stratospheric ozone depletion, acid precipitation, urban air pollution, and loss of biodiversity.
Global change is the term used to encompass multiple environmental and ecological changes. Global change encompasses the study of climate change, species extinction, land use change, as well as many other areas. Many university courses are titled Global Change.
