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

Current Editorial
The Hockey Stick, the Little Ice Age and the Medieval Warm Period: Guest Editor Gerald T. Westbrook, chemical engineer and energy economist, takes a critical look at the climate history of the last millennium.

Subject Index Summaries
Aerosols (Biological - Aquatic): Aerosol-producing biological processes that occur in the upper layers of the world's oceans preside over a number of interrelated physical phenomena that act to resist extreme changes in global air temperature and thus maintain earth's physical environment in a state conducive to the continued proliferation of life.

Trees (Types - Aspen): A review of the recently published literature suggests that increases in the air's CO2 content will enhance photosynthetic rates and biomass production in aspen trees, which are the most widely distributed type of tree in North America.

Carbon Sequestration Commentary
Another Global Warming Horror Story Bites the Dust: Climate alarmists have long and vociferously argued that global warming would greatly enhance the evolution of CO2 from boreal peatlands as they experience the melting of permafrost, which consequence, they further claim, would catastrophically exacerbate the putative CO2-induced increase in air temperature.  Real-world data, however, suggest just the opposite, i.e., that the melting of permafrost in boreal peatlands will actually result in the biological sequestration of more carbon.

Current Journal Reviews
Millennial-Scale Climatic Oscillations in Central Chile: Not only do they correspond with European records of the Medieval Warm Period and Little Ice Age, they also correspond with European records of the earlier Roman Warm Period and Dark Ages Cold Period.

Windier Winters Over the North Sea: Brrrr!  The very thought of it makes us shiver.  Is this global warming or what?

Effects of Elevated CO2 and Temperature on Saltmarsh Plants: Increasing atmospheric CO2 concentrations and rising air temperatures will likely lead to a poleward expansion of saltmarshes and a greater amount of carbon being sequestered within them.

Shade Tolerance in Woody Species: Does It Enhance or Hinder Growth Response to Elevated CO2?: An analysis of 74 individual experimental results reveals the answer.

Elevated CO2 Enhances Flower Power of USA Plant: Enriching the air with CO2 induced earlier flowering and increased flower biomass in Heterotheca subaxillaris, a common annual plant that is native to the southeastern United States.
