Appeal by American Scientists to Prevent Global Warming
Global warming has emerged as the most serious environmental threat of the 21st century. There is broad agreement within the scientific community that amplification of the earth’s natural greenhouse effect by the buildup of various gases introduced by human activity has the potential to produce dramatic changes in climate. The severity and rate of climate change cannot yet be confidently predicted, but the impacts of changes in surface temperature, sea level, precipitation, and other components of climate could be substantial and irreversible on a time scale of centuries. Such changes could result in severe disruption of natural and economic systems throughout the world.
