Temperature Record of the Week
This issue's Temperature Record of the week is from Lake City, Florida. Visit our U.S. Climate Data section to plot and view these data for yourself.

Current Editorial
What Kills People During Air Pollution Episodes?: The answer would seem to be a no-brainer - air pollutants, right? To some extent, that is correct, especially when pollutant concentrations are abnormally high. But under less extreme conditions typical of the vast majority of pollution episodes in most of the world's larger cities, the authors of an intriguing new study suggest something else is actually the culprit.

Subject Index Summaries
Arctic Temperature Trends: We review several recent papers describing temperature trends in the Arctic, for this is the place where climate alarmists claim CO2-induced global warming should be first and most obviously evident.  But is this review really necessary?  Haven't the CO2 vilifiers already announced that the dreaded day is upon us?  ... and that the planet has been sweltering in it for at least the past two decades?  Why bother with data?

Forests (Growth Response to CO2): The scientific literature continues to indicate that as the air's CO2 content continues to rise, earth's forests will likely display enhanced rates of photosynthesis and biomass production, thereby leading to greater carbon sequestration within their woody tissues and the soils in which they grow.

Carbon Sequestration Commentary
Planetary Carbon Sequestration: Earth's Biosphere Flexes Its Muscles: Averaged over the globe, the anthropogenic CO2 emission rate has risen nearly 40% over the past two decades, yet the rate at which CO2 is accumulating in the atmosphere has remained constant or even slightly declined.  Why?

Current Journal Reviews
A Thousand-Year Record of Typhoons in Southern China: If, as climate alarmists are quick to claim, the past century's global warming was truly "unprecedented" within the context of the last millennium, and if warmer temperatures truly spawn more frequent and intense weather events, as they are also quick to claim, this incredible weather history from southern China should be just what they've been looking for to prove their case.

The Little Ice Age and Medieval Warm Period: Were They Real?: Does the sun rise in the east?

Antarctic Sea-Ice Trends: They provide a nice touch of reality in a world of highly-hyped but imaginary global warming phenomena.

Elevated CO2 and Plant Disease: Is There a Detrimental Connection?: Quite the contrary.  In the study here reviewed, atmospheric CO2 enrichment completely alleviated the yield-reducing effects of fungal pathogenic attack in hydroponically-grown tomato plants.

Effects of Elevated CO2 and Soil Nitrogen on Sixteen Grassland Species: Atmospheric CO2 enrichment enhanced total biomass production in forbs, legumes and C3 grasses, irrespective of soil nitrogen availability, while it simultaneously increased soil water contents beneath C3 grasses, C4 grasses and forbs.
