Current Editorial
Atlantic Hurricanes: Their Response to Global Warming: We respond to some challenging critical comments made by Mike MacCracken about this topic.

Subject Index Summaries
Hurricanes (Indian Ocean): Tropical cyclones in the Indian Ocean have the potential to wreck great havoc on large numbers of people in low-lying coastal areas.  What can we expect in the way of changes in these storms if the planet continues to warm in the 21st century as it did in the 20th century?

Trees (Type - Fruit-Bearing): Nearly all woody plants respond to increases in the air's CO2 content by displaying enhanced rates of photosynthesis and biomass production.  In this summary, we review the results of several recent studies of fruit-bearing trees within this context.

Current Journal Reviews
Gulf of Mexico Landfalling Hurricanes: Are they becoming more frequent?  Are they getting stronger?  Are we all doomed?

A Drought History of Northern California and Nevada, USA: Information gleaned from sediment cores taken from Pyramid Lake, Nevada, suggests that a drought greater than any of the historical past could well envelop much of the country, independent of any of the activities of man.  No wonder climate alarmists predict such catastrophes: they don't have to be right to have their predictions come to pass!

Pollen Production by Ragweed in a Doubled-CO2 Atmosphere: Is it really enhanced?  Yes.  Is it really bad?  No.

The Relationship between Grain Yield and Protein Content in Wheat: In a review of a number of their prior experiments, the authors discuss the relationship between grain yield and protein content of spring wheat within the context of variations in atmospheric CO2 and ozone concentration and plant water stress.

Carbon and Nitrogen Uptake in Beech Seedlings Exposed to a Doubled Atmospheric CO2 Concentration: How is the uptake of the two elements altered?  Are there differences in allocation among plant organs?  What are the implications for the future?
