Elevated CO2: What Can It Do for Semi-Arid Shortgrass Steppe Vegetation?: Plenty.

Subject Index Summaries
Droughts (North America: United States): Climate alarmists claim that global warming will result in ever-worsening drought conditions.  A good test of this claim is to see what the global warming of the past century or two has wrought in this regard.  Hence, we present a brief review of this subject as it pertains to the United States of America.

Seeds (Grasslands): How do elevated levels of atmospheric CO2 impact the production and properties of the seeds of the plants that comprise natural grasslands and managed pastures? and what are the ramifications of these phenomena?

Journal Reviews
Is There an Ice Age on the Horizon?: Perhaps; but some important new evidence suggests it may be a long time getting here.

Eight Centuries of Indian Ocean Monsoon Rainfall Data: What do they tell us about the ability of general circulation models of the atmosphere to simulate monsoonal circulations and their response to global warming?

Millennial-Scale Variations in West African Precipitation: Evidence continues to accumulate for the existence of a millennial-scale oscillation of climate that alternately brings each part of the world either warmer or cooler and/or wetter or drier conditions as time marches on.

The Photosynthetic Response of Soybeans to Elevated CO2: A new study reveals a strong response of soybean leaf photosynthesis to atmospheric CO2 enrichment, while theoretical calculations suggest that the CO2-induced increase in photosynthetic prowess is still only half as strong as it has the potential to become.

Response of Spring Wheat to Elevated CO2 and Ozone: Sometimes, atmospheric CO2 enrichment actually more than completely ameliorates the damage caused to plants by ozone pollution.
