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

Current Editorial
Has CO2-Induced Global Warming Been Wrongly Accused of Decimating Cloud-Forest Ecosystems?: With the publication of an important new paper in Science, it's sure beginning to look that way.

Subject Index Summaries
Medieval Warm Period (Europe): Climate alarmists have gone to great lengths over the past few years to try to convince the world that the earth is currently a much warmer place than it was at any other time during the past millennium.  The Medieval Warm Period is thus a major embarrassment to them; and they have consequently decreed that it never occurred over most of the planet, and that where it did occur, it was really not all that warm.  A heck of a lot of data, however, say otherwise; and in this summary we report on some that comes from Europe.

Nitrogen Use Efficiency: As the air's CO2 concentration rises, plants will likely respond by exhibiting greater rates of photosynthesis while simultaneously reducing their foliar concentrations of nitrogen, which phenomenon effectively increases plant photosynthetic nitrogen-use efficiency.

Carbon Sequestration Commentary
Recent Studies Show Global Warming May Enhance Soil Carbon Storage and Thereby Slow Its Own Progression: Long-held beliefs about the temperature dependency of ecosystem net CO2 exchange rate - and, therefore, ecosystem carbon sequestration potential - are inexorably crumbling before the advancing tide of real-world scientific research.

Current Journal Reviews
A 700-Year History of Baffin Bay Sea-Ice Extent: Once again, real-world data reveal something quite different from what climate alarmists call recent unprecedented warming.  Would you believe a return to Little Ice Age conditions?  No, that's not possible, is it?

The Little Ice Age in China: Evidence continues to accumulate to refute some of the favorite claims of climate alarmists who view the rising CO2 content of earth's atmosphere as - according to an advertisement for the new book Climate Change: Science, Strategies & Solutions (Eileen Claussen, Editor) - "the greatest environmental challenge of the 21st Century."

Ice Shelf Behavior Along the Coast of Queen Maud Land, Antarctica: The ice shelves in question have lost about 6.8% of their area over the past 34 years.  Should we all relocate to higher ground?

Effects of Elevated CO2 on Pine Tree Seeds: Loblolly pine trees exposed to 560 ppm CO2 in a FACE experiment located in North Carolina, USA, produced seeds that had greater lipid contents and overall weights than seeds produced on trees exposed to ambient air.  Read on to learn how these differences impacted germination success and early seedling development.
