Editorial
Coral Reefs: Past, Present and Future: The authors of a recent review paper describe (1) what we know about past changes in coral reefs in relation to temperature, (2) what appears to be happening currently in this regard, and (3) what these observations portend about the future of earth's coral reefs.

Subject Index Summaries
Roman Warm Period (North America): It is typically manifest in proxy evidences of warmer temperatures and reduced hydrologic activity.

Phytoplankton (Growth Response to CO2): Will the ongoing rise in the air's CO2 content enhance the productivity of marine and freshwater phytoplankton in the way it enhances the productivity of terrestrial plants?

Journal Reviews
United States Thunderstorm Activity: How has it varied over the course of the 20th century?  And what do the results imply about its relationship to global warming?

Summer Soil Moisture in the Ukraine: How have climate models suggested it should have varied over the past half century?  How has it really varied?

Earth Surface Reflectance Data and the Aerial Fertilization Effect of CO2: Do satellite-derived reflectance data provide evidence for the phenomenon behind the 20th-century greening of planet earth?

Effects of Elevated CO2 on Growth and Water Relations of Sorghum: Will a C4 crop like sorghum be benefited by rising atmospheric CO2 concentration?  And if so, will the benefit be big enough to overcome the presumed negative consequences of a significant concomitant increase in air temperature?

Mortality in London: Summer Heat vs. Winter Cold: Which extreme is most to be feared?
