Assembled by the United Nations in an attempt to arrive at an international consensus on global warming, a team of scientists says it is a ”virtual certainty” that the temperature of the earth’s surface will rise substantially in the next century.

So far this century we have had zero warming.

The scientists generally agree with the theory that has been largely accepted by other national and international panels: that energy trapped in a greenhouse effect by industrial gases will warm the earth by 3 to 8 degrees Fahrenheit within the next 60 years.
