Forest Responses to Global Warming: We discover a photocopy of a 1998 paper in our office one day (none of us knows how it got there) that provides a fascinating perspective on one of the climate alarmists' favorite scare stories, i.e., the claim that CO2-induced global warming will force many of earth's trees to begin migrating to cooler regions at rates they cannot possibly sustain, leading to their eventual extinction.

Subject Index Summaries
Glaciers (Arctic): Climate model simulations suggest Arctic glaciers should be rapidly melting in response to "unprecedented" CO2-induced global warming.  Are they?

Insects (Butterflies and Moths): A review of the literature was performed to determine if feeding upon CO2-enriched foliage impacts the feeding, development, and growth of butterflies and moths.

Current Journal Reviews
Cooling on the Horizon?: Fluctuating basin-wide fish populations suggest the Pacific Ocean may have entered a natural cooling phase that may presage an end to the "unprecedented" warming of the last two decades of the 20th century.

A 500-Year History of Drought in the Pacific Northwest, USA: What can it tell us about the climate-alarmist claim that global warming increases the frequency of severe droughts?

Effects of Elevated CO2 in a Maturing Scrub-Oak Ecosystem: Atmospheric CO2 enrichment generally increases photosynthetic rates and biomass production in seedlings and saplings.  However, the responses of maturing trees in closed-canopy ecosystems are poorly understood and deserve greater attention, which this paper provides.

Effects of Elevated CO2 and Shading on Potato Growth: Elevated CO2 can significantly increase potato tuber biomass.  However, the underlying mechanisms responsible for this observation are not completely understood.  In this paper, the authors study CO2-induced increases in tuber biomass at two plant growth stages and in two light environments in an attempt to clarify the growth-promoting mechanisms.

Effects of Elevated CO2 on Nitrogenase Activity in Soybeans: Nitrogen-fixing bacteria associated with the roots of leguminous plants utilize the enzyme nitrogenase when converting atmospheric nitrogen to the more-plant-usable NH4⁺.  Will increasing atmospheric CO2 concentrations affect the activity of this important plant enzyme?
