Marrickville - People Against Global Warming

By burning fossil fuels, mankind has been adding gases to the atmosphere that tend to warm the earth, known as "greenhouse gases." In the coming decades, we are likely to continue to change our atmosphere. Because the greenhouse gases that warm the earth stay in the atmosphere longer than the aerosols that cool the earth, the earth's average temperature will continue to warm.

The continued addition of greenhouse gases to the atmosphere will raise the earth's average temperature by several degrees in the next century, which will in turn raise the level of the sea. In the future, most of the world is expected to warm. Scientists are currently unable to determine which parts of the world will become wetter or drier, but there is likely to be an overall trend toward increased precipitation and evaporation, more intense rainstorms, and drier soils.
