Since the beginning of the industrial revolution, atmospheric concentrations of carbon dioxide have increased nearly 30%, methane concentrations have more than

doubled, and nitrous oxide concentrations have risen by about 15%. Because of the increase of concentrations of these gasses, more energy is trapped within the Earths atmosphere, which is slowly increasing the average heat levels. Scientists predict that the average temperature will rise 1.6 - 6.3°F by the year 2100, which could wreak havoc with climates around the world.

As of September 1997, over 30 states had become partners in the State Outreach program. Most have completed state greenhouse gas inventories. Nearly 20 are working on, or have completed, action plans that identify cost-effective options for reducing greenhouse gas emissions. Some of the efforts focusing on cities and counties is being coordinated by the International Council for Local Environmental Initiatives (ICLEI), a non-governmental en
