Enhanced Greenhouse Effect
The greenhouse effect is a natural process. Greenhouse gases in
the atmosphere trap the sun's warmth,
raising the temperature on earth. Without the greenhouse effect,
the earth would be too cold for human habitation.
Most greenhouse gases have natural as
well as human-made sources, and there
are natural mechanisms for removing them from the atmosphere.
However, human activities are increasing the atmospheric concentrations
of greenhouse gases, and more gas is being emitted than is being
absorbed naturally each year. This overload of gases is leading
to global warming and climate
change.

to emission targets visit the Australian
Greenhouse Office website.
