Was There a 15th-Century "Little" Medieval Warm Period?: In scrutinizing some of the papers we have recently reviewed in the pages of CO2 Science Magazine, we are finding more and more evidence for a period of time in the vicinity of the 15th to 16th century transition when surface air temperatures, like those of the central core of the Medieval Warm Period, appear to have rivaled - or even exceeded - those of the Modern Warm Period.

Subject Index Summaries
Snow (North America): Temporal trends of various properties of snow over different parts of North America provide little evidence for a number of claims routinely made by climate alarmists intent on painting anthropogenic CO2 emissions as the mortal enemy of a benign earthly climate.

Seeds (Trees): As the air's CO2 content continues to rise, how will the reproductive capacities of earth's forests be affected?

Journal Reviews
How "Pristine" are the Surface Air Temperature Data that Suggest an "Unprecedented" Global Warming Over the 20th Century?: The question is a valid one that deserves an honest answer, especially in view of the radical -- and radically expensive -- energy policies that climate alarmists use the data to justify.

Two Centuries of Runoff and Floods in Sweden: Have floods in Sweden become more frequent and extreme as the earth has emerged from the Little Ice Age and entered the Modern Warm Period?

Global Warming and Malaria in the East African Highlands: Is the latter promoted by the former?

Calcification Response of Porites Corals to Global Warming: Climate alarmists continue to claim that the "twin evils" of rising temperatures and atmospheric CO2 concentrations will doom earth's corals to extinction.  Are they right?

Elevated CO2 vs. O3-Induced Stress in Aspen and Birch Trees: Which comes out the winner when the air's O3 concentration is increased by 50% and its CO2 concentration is enhanced by 55%?
