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

Did Increasing Solar Activity Drive 20th-Century Global Warming?: A recent study suggests it played a major role, if not the major role, in orchestrating the temperature rise that climate alarmists primarily attribute to the concomitant increase in the air's CO2 content.

Medieval Warm Period Records of the Week
This issue's Medieval Warm Period Records of the Week come from Lake Caveiro, Pico Island, Azores and Lake Nakatsuna, Japan.  To access the entire Medieval Warm Period Project's database, click here.

Subject Index Summary
Respiration (Response to CO2 - Woody Plants: Deciduous Trees): Are respiration rates of deciduous trees enhanced or suppressed in CO2-enriched air?

Journal Reviews
Surface Air Temperature Trends in Central California, USA: What do they reveal about anthropogenic-induced climate change?

Arctic Eurasian Precipitation: 1936-1999: Did it significantly increase in response to concomitant global warming, as climate models suggest it should have done?

The Pan-Arctic Shrub Expansion: What is it? ... and what's causing it?

The Effect of Elevated CO2 on the Optimum Temperature for Photosynthesis in Rice: Does atmospheric CO2 enrichment make it easier or more difficult for rice to cope with higher air temperatures?

Nitrogen Uptake by Soil Microbes: The Long (Term) and the Short (Term) of It: Another paper looks at the progressive nitrogen limitation hypothesis and finds it wanting.
