The Impact of Global Warming on Frog Populations (06 Oct 2010)
McCaffery and Maxell (2010) write that "researchers have typically assumed that if climate change affects amphibian species, the outcome will be negative," and they note, in this regard, that "rarely do we allow ourselves to consider that global warming may confer benefits to some species." Fortunately, they were able to break out of this thought-confining view of the subject and look at things more realistically... Read More
Intense Tropical Cyclones in a Warming World (06 Oct 2010)
Climate alarmists have long claimed that global warming will lead to the more frequent occurrence of stronger tropical cyclones, but this contention has not been proven to be correct... Read More
Allergenic Pollen in Cities of Northwest Spain (06 Oct 2010)
In spite of the fact that there was a "significant trend towards increasing temperatures over the months prior to the onset of the pollen season," observations reveal that Poaceae pollen actually became far less of a negative health factor in the four Galician cities over the decade and a half studied, which findings run counter to claims that global warming will increase allergens...

The Effect of Nitrogen Deposition on Forest Soil Respiration (06 Oct 2010)
Nitrogen Deposition stimulates plant growth and the uptake of carbon from the atmosphere, and a new study reveals that it is "the dominant driver of carbon sequestration in forest ecosystems," although the magnitude of its effects have not been included in current carbon-cycle models... Read More
Dimethylsulfide, Global Warming and the Arctic Ocean (06 Oct 2010)
What does the future hold with respect to their interactions? Results from this study suggest it will lead to "a great impact on the Arctic energy budget [that] may offset the effects of anthropogenic warming that are amplified at polar latitudes"... Read More
Life in Alpine Regions in a Warming World (06 Oct 2010)
A frequent contention of CO2-induced global warming is that alpine species will be pushed off the planet, driven to extinction by increasing temperatures. But is this claim correct?... Read More

The IPCC Spaghetti-Diagram Reconstructions of Paleoclimate are Incoherent With Each Other (13 Oct 2010)
Using spectral coherence methods, the paleo-reconstructions used in the IPCC spaghetti graph were evaluated for similarity of pattern over time. It was found that five clusters of reconstructions were internally coherent, but that the different clusters were not coherent with each other. This means there is no agreement between these reconstructions, whatever the visual appearance may be, and that there is no way to "average" them in any meaningful way... Read More
A Millennium of Reconstructed and Simulated Temperatures for Eastern China (13 Oct 2010)

The Fate of Coastal Wetlands in a Warming and CO2-Accreting Atmosphere (13 Oct 2010)
The alarmist school of thought is that they are destined to be submerged by rising sea levels, as glaciers and polar ice sheets melt at ever-increasing rates. Real world observations, on the other hand, suggest otherwise... Read More
Battling for Fungal Sporocarps in Earth's Forests: CO2 vs. O3 (13 Oct 2010)
By itself, or in combination with rising ozone concentrations, the ongoing rise in the air's CO2 content appears likely to enhance the genetic recombination and long-distance dispersal of the ectomycorrhizal fungi that form symbiotic relationships with the roots of aspen and birch trees, thereby positively contributing to various food webs that will be found within aspen and aspen-birch forests of the future... Read More
The Response of Heterotrophic Soil Respiration to Warming (13 Oct 2010)
A frequent contention of CO2-induced global warming is that "it is often assumed that warming will stimulate carbon dioxide release from soils," resulting in a positive feedback that amplifies warming. The results of a new study, however, indicate that the notion of soil respiration rising in response to global warming, and remaining high, is far from the truth... Read More

Warming Enhances Plant Growth (14 Oct 2010)
A meta-analysis of 127 studies was conducted to evaluate the effects of warming on plant growth. It was found that most plant types responded positively (increased biomass) to warming of up to 6°C, with trees responding most positively... Read More
They've Left Life Out of the Equations ... (20 Oct 2010)
In a highly-hyped paper that appeared in the 15 October 2010 issue of Science, four researchers from NASA's Goddard Institute for Space Studies claim that atmospheric CO2 is the "principal control knob governing earth's temperature," being correct in one sense, but wrong in another ... Read More
Tropical Cyclones of the North Atlantic (20 Oct 2010)
Some researchers contend that global warming increases tropical cyclone (TC) and hurricane (H) activity, and that the past several years have provided evidence for this effect. Others, on the other hand, attribute the enhanced TC and H activity of the recent past to the occurrence of the positive state of a natural decadal-scale cycle that leads to periodic ups and downs in TC and H numbers and intensities. Who is right? ... Read More

Old Trees Growing in a CO2-Accreting Atmosphere (21 Oct 2010)
In an analysis published in the Journal of Integrative Plant Biology, Phillips et al. note there is "a long held view," as they describe it, that "old trees exhibit little potential for growth." Hence, they say "it may seem reasonable to conclude that old trees are not responsive to increased CO2," as many do indeed claim. They go on, however, to demonstrate that this view is likely far from the truth ... Read More
