Editorial
U.S. Climate Change and Its 20th-Century Biological Consequences: The findings of a new study imply that climate-alarmist projections of future species extinctions may be overly pessimistic.

Subject Index Summary
Methane (Atmospheric Concentrations): Atmospheric methane's contribution to anthropogenic climate forcing is estimated to be about half that from CO2 when both direct and indirect components of its forcing are summed; and model projections of future climate change generally all project an increase in atmospheric CH4 for at least the next 3 decades, with many of the scenarios predicting large increases through the 21st century. Thus, it is important to compare these projections with relevant observations; and when this is done, likely future increases in atmospheric methane fall far short of what has long been predicted.
