Climate agenda

Climate change is one of the top environmental issues, with liberals and conservatives evenly divided on whether recent global warming is more natural or man-made.

The main contention of environmentalists like Al Gore is the argument that:

1. The earth's atmosphere warmed one or two degrees Fahrenheit (0.8 Centigrade) during the 20th century.
2. Most of this warming is man-made.
3. The warming is likely to continue and to be harmful to human, animal and plant life.
4. We must all work together to stop it by reducing emission of "greenhouse gases".
