The term given to the various impacts of rising levels of greenhouse gases on Earth¡¦s climate. These effects include global warming, weather changes, and a rising sea level.
The temperature of earth has fluctuated considerably over millions of years. Global climate change associated with human activity is the study of the dynamic changing of earth's surface temperature and the altering of weather patterns associated with the greenhouse effect.
Global climate change can have a wide variety of impacts depending upon your location.
a change in the world's climate
natural or human induced change in the average global temperature of the atmosphere near the Earth’s surface. This condition poses serious dangers around the world, potentially prompting such disasters as flooding, drought, and disease.
Sometimes used to refer to all forms of climatic inconsistency; in other cases used as a synonym for global warming.
Global climate change is a significant alteration from one climatic condition to another, beyond the usual alterations in various climates throughout the globe, as the result of human activities. The greatest of these is fossil fuel combustion, which traps greenhouse gases in the atmosphere that cause gradual changes in Earth’s temperatures over hundreds of years. The term “global warming†may also be used but refers more specifically to temperature, whereas global climate change encompasses the broader changes associated with elevated greenhouse gas levels, such as dryer deserts, increased numbers of hurricanes, and warmer oceans.

Global climate change could result in sea level rises, changes to patterns of precipitation, increased variability in the weather, and a variety of other consequences. These changes threaten our health, agriculture, water resources, forests, wildlife, and coastal areas.

Gradual changing of global climates due to the buildup of carbon dioxide and other greenhouse gases in the earth's atmosphere. Carbon dioxide produced by burning fossil fuels has reached levels greater than what can be absorbed by green plants and the seas.
An interconnected chain of climatic events brought about by an increase in trapped heat in the atmosphere. The trapped heat alters atmospheric processes and their interaction with the oceans and the land. The climate--the product of that interaction--changes as well, causing altered weather patterns that bring unexpected rain or dry spells, sudden severe storms and temperature changes.
