Oceanic Dimethylsulfide Production in a CO2-Enriched and Warmer World (03 Nov 2010)
Kim et al. write that "in the context of global environmental change, the key implication of our results is that DMS production resulting from CO2-induced grazing activity may increase under future high CO2 conditions," and, therefore, they conclude that "DMS production in the ocean may act to counter the effects of global warming in the future."...

The Ups and Downs of Tropical Cyclone Activity in the Western Hemisphere (03 Nov 2010)
Tropical cyclone activity over the North Atlantic and eastern North Pacific ocean basins, as a whole, has experienced little variability on either interannual or multidecadal timescales; and real-world empirical data suggest that the variability that does exist over the conglomerate of the two basins has grown slightly weaker as the earth has warmed over the past six decades, which runs counter to climate-alarmist claims that earth's hurricanes or tropical cyclones should become more numerous, stronger and longer-lasting as temperatures rise...

Did they really occur? ... and what do the results imply?... Read More
Surviving the Perfect Storm (03 Nov 2010)
Godfray et al. (2010) note that "more than one in seven people today still do not have access to sufficient protein and energy from their diet and even more suffer some form of micronutrient malnourishment." What does this have to do with the rise in atmospheric CO2?... Read More
The Medieval Warm Period in China's Tarim Basin (03 Nov 2010)
Authors Ma et al. analyzed multi-proxy data, which they obtained from sediment retrieved from excavations made in the dry lake bed of Lop Nur China's West Lake (40°27'129" N, 90°20'083" E) -- in order "to amply discuss," as they describe it, "the climate and environment changes during the MWP," or Medieval Warm Period. So what did they find?... Read More
High-Temperature-Induced Male Sterility in Crop Plants (04 Nov 2010)
If portions of the earth ever do warm to where high temperatures begin to significantly reduce crop yields via induction of male sterility, there is a substance that can function as both a herbicide and a fertility restorer that has already been successfully used for the former purpose and that can now provide dual benefits...

Predictions of Impacts of Climate Change on Animal Species Suffer From Model Discrepancies (04 Nov 2010)
This study used projections of climate for Spain to compute habitat suitability for four animal species. They found that the two climate models they tested produced results that differed more than the results from the two emissions scenarios, showing that there is not sufficient model agreement to allow models to be used to infer species habitat impacts over the next 100 years...

Can an EPA-Certified Air Pollutant Counteract the Botanical Harm Caused by a Bona Fide Soil Pollutant? (10 Nov 2010)
It sure can, and in the words of Jia et al. "given expected global increases in CO2 concentration, elevated CO2 may help plants better survive in contaminated soil and reduce the food safety risk due to CO2-induced reduction and dilution in heavy metal concentration"... Read More

Floods of the Mississippi River System (10 Nov 2010)
A common claim of the IPCC is that flooding becomes more frequent and severe in response to global warming; and as a result, whenever and wherever such a trend may manifest itself, radical environmentalists are quick to attribute it to anthropogenic CO2 emissions. But could there be other things behind such tendencies?... Read More
The Effects of Warming on Winter Wheat Yields in Semi-Arid China (10 Nov 2010)
Even without the benefits of the aerial fertilization effect and the anti-transpiration effect of the ongoing rise in the air's CO2 content, the increase in temperature that is predicted by climate models for the year 2050, if it ever comes to pass, will likely lead to increases in winter wheat production in the northwestern part of China, not the decreases that climate alarmists routinely predict...

What do sedimentary archives of the region suggest about it?... Read More
Soil Microbial Respiration (11 Nov 2010)
Climate alarmists contend that increases in terrestrial ecosystem respiration, as temperatures warm, could create a positive feedback that causes atmospheric CO2 concentration, and subsequently global temperature, to increase more rapidly. Yet, plant tissue respiration acclimates to temperature over time, weakening this feedback loop over time and reducing the potential temperature increase. In this study, the authors find a similar acclimation in soil respiration... Read More

Real-World Increase in Air's CO2 Content Has Accelerated Growth of Natural Aspen Stands (16 Nov 2010)
Young trees grew faster in recent years than did young trees several decades ago such that "the effect of rising CO2 [was] to increase ring width by about 53%," as a result of "a 19.2% increase in ambient CO2 levels during the growing season, from 315.8 ppm in 1958 (when CO2 records began) to 376.4 ppm in 2003."...

ENSO Activity and Climate Change (17 Nov 2010)
The finding of "similar century-scale variability in climate archives from two El Niño-sensitive regions on opposite sides of the tropical Pacific strongly suggests that they are dominated by the low-frequency variability of ENSO-related changes in the mean state of the surface ocean in [the] equatorial Pacific." And that "century-scale variability," as the authors of this paper describe it, suggests that global warming typically tends to retard El Nino activity, while global cooling tends to promote it...

A Newly-Discovered Benefit of Mycorrhizal Fungi (23 Nov 2010)
As the air's CO2 content rises, it will likely impact crop-fungal interactions by increasing the percent of the crop's root system colonized by either mycorrhizal fungal hyphae or arbuscular structures, thereby promoting the ability for crops to suppress growth of some aggressive agricultural weeds...

Effect of Elevated CO2 on Calcification by Oculina arbuscula Corals (23 Nov 2010)
The IPCC contends that rising atmospheric CO2 concentrations will lead to a significant acidification of seawater that will in turn lead to significant -- and likely deadly -- reductions in coral calcification rates. New research, however, calls this claim into question... Read More

Holocene Climatic Change in the North American Great Plains (24 Nov 2010)
It appears that for a broad swath of the midsection of the United States stretching from the center of Texas all the way to the U.S. border with Canada, the supposedly unprecedented warming of the 20th century was not unprecedented at all, having likely been surpassed one thousand, two thousand and four to five thousand years ago, when there was much less CO2 in the air than there is today...

At moderate temperatures, such as those to which the bryozoans studied in this experiment are currently adapted, "adult M. truncata are able to up-regulate their calcification rates and survive in areas with higher levels of pCO2 than are predicted to occur due to anthropogenic ocean acidification, whcich is good news for those worried about possible dire consequences of ocean acidification on marine organisms...
