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

The Capacity of Man and Nature to Control Climate Change: If man begins to adversely perturb earth's climate system, can the rest of the biosphere forestall the potential negative consequences?  Marine phytoplankton may be able to do just that.

Subject Index Summaries
Antarctica (Glaciers): Does historical glacial activity on the coasts of Antarctica harmonize with the climate-alarmist "hockeystick" temperature history of the IPCC?  Or is it more in line with the naturally-occurring millennial-scale oscillation of climate for which ever more evidence becomes available almost weekly?

Algae: The effects of simple algae on earth's diverse ecosystems is simply astounding, and the ongoing rise in the air's CO2 content is likely magnifying their significance even more.

Journal Reviews
The Urban Heat Island of Shanghai, China: How has it changed over the past two decades?  And why?

A 423-Year Record of the Atlantic Multidecadal Oscillation (AMO): Tree-ring based proxy records of low-frequency (60-100 years) variability in North Atlantic basin-wide sea surface temperatures "confirm that the AMO should be considered in assessments of past and future Northern Hemisphere climates."

Insect Damage of Myrtle Oak Trees Exposed to Elevated CO2: Is it greater or less than the damage experienced by myrtle oak trees growing in ambient air?

Effects of Elevated CO2 on Plant Nutritional Quality and Subsequent Herbivory by Moth Larvae: Do CO2-induced decreases in the protein contents of C3 and C4 grasses lead to greater foliage consumption by caterpillars that feed on them?

The Photosynthetic Response of a Marine Diatom to Atmospheric CO2 Enrichment: Do the microscopic algae that inhabit the earth's oceans and comprise the foundation of the marine food chain respond to atmospheric CO2 enrichment?
