Editorial
Global Primary Productivity and Climate Change: Just how much power does the former exert over the latter?

Subject Index Summaries
Little Ice Age (Europe: Central): What do we know about the Little Ice Age as it was expressed in Central Europe?  And what does that knowledge imply about past and current warmth?

Pathogens : Which way will the ongoing rise in the air's CO2 content tip the "balance of power" between earth's plants and the pathogens that continually challenge them?

Journal Reviews
Solar Irradiance and Arctic Temperatures: For years, climate alarmists have been telling us that rising atmospheric CO2 concentrations have been driving Arctic air temperatures ever higher.  A new study challenges this claim.

Pollution, Aerosols and Cloud-Top Temperatures: How are they related, and what do they have to do with global warming?

Medieval Drought in the USA's Central Great Plains: More evidence that the Medieval Warm Period was holding sway in North America a thousand years ago.

Carbon Dioxide and Cold-Weather Stress in a Tropical Tree: Do elevated levels of atmospheric CO2 exacerbate or ameliorate the problem?

A Half-Century Forward Look at Agricultural Production in Canada's Atlantic Provinces: One might expect that global warming would have a positive impact on the agricultural production of a high northern-latitude country such as Canada; but just how large might that impact be?
