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

Current Editorial
Does the Sun Control Everything Climatic?: New evidence of the power of the sun to set the agenda for climate change on earth should give everyone pause to "look before they leap" into the mindless morass of the Kyoto Protocol.

Subject Index Summaries
Agriculture (Species -- Wheat): How will the ongoing rise in the air's CO2 content affect the production of wheat in the years and decades ahead?  Will the global grain harvest be large enough to give us all our daily bread?

Holocene (Solar Effects on Climate): All sorts of palaeoenvironmental data demonstrate that the millennial-scale climatic oscillation that has reverberated throughout the Holocene has been driven by similar-scale variations in solar activity.  Hence, it is abundantly clear that such mini-climatic epochs as the Roman Warm Period, Dark Ages Cold Period, Medieval Warm Period and Little Ice Age - as well as the Modern Warm Period - have come to us courtesy of periodic phenomena originating in the sun.

Carbon Sequestration Commentary
Carbon Sequestration by a Subarctic Sedge Fen: Will northern peatlands release massive amounts of carbon to the atmosphere if the temperature trend of the past century ultimately returns the earth to a climatic condition similar to that of the Medieval Warm Period?  Climate alarmists would have you think yes; but if you did ... you'd be thinking wrong.

Current Journal Reviews
A 12,000-Year Record of Climate Change in Australia: Oh, for the good old days ... of the mid-Holocene.

The Greenland Ice Sheet is Melting!: From beneath, that is.

Carbon Sequestration in Marine Communities: The preservation and proper management of coastal marshes may well be a policy goal about which all environmentally-minded people concerned - or not concerned - about the possibility of CO2-induced global warming could agree.

Grasslands Increase Carbon Stocks in Simulation Study: A mechanistic pasture simulation model was run with elevated CO2 and air temperature to predict the responses of differently-managed grasslands to these environmental variables.

Effects of Elevated CO2 on a Tropical Orchid: Atmospheric CO2 enrichment increases growth and biomass production in nearly all C3 species.  But how does it perform in the case of an epiphytic orchid that employs CAM metabolism?
