Urban Atolls of the World's Oceans: Succumbing to Rising Seas? (5 June 2012)
Don't bet on it, as the author of this report reports that "the notion that sea level rise is a singular driver of shoreline change along atolls is spurious," adding that "adopting such a notion is an impediment to the sustainable management of coastal resources within urban atolls"... Read More
The Current High-Frequency Dynamics of Ocean pH (5 June 2012)
Ocean pH measurements reveal "biome-specific pH signatures [that] disclose current levels of exposure to both high and low dissolved CO2, often demonstrating that resident organisms are already experiencing pH regimes that are not predicted until 2100." And these facts suggest that the current real-world heterogeneity of the world's oceans with regard to pH and pCO2 exposure may indeed "result in populations that are acclimatized to variable pH or extremes in pH," such as those that have been predicted to be the new norm in 2100...

Harbor Porpoises Benefit from Reduced Winter Sea Ice off West Greenland (5 June 2012)
Harbor porpoises sampled off West Greenland were in better condition during a recent period of warm water and reduced winter sea ice than they were during a cold period in the 1990s... Read More
The Health and Productivity of Diatoms in Acidified Seawater (6 June 2012)
Would a doubling of the atmosphere's CO2 concentration have a hugely negative effect on them? According to the authors of this study, if all diatoms responded in similar fashion to T. pseudonana, ocean acidification may have "little effect on diatom productivity"... Read More
Population Demographics and Heat-Related Mortality (6 June 2012)
How significant is the relationship between the two? According to the three researchers who conducted this study, "at least in Massachusetts, an area's demographics may be more important to its heat-related mortality than its level of urbanization"... Read More
The Evolving Status of the Western Greenland Ice Sheet (6 June 2012)
There is still much to learn about it; and with each new study of the subject, the probability of a CO2-induced temperature collapse of the ice sheet seems less and less likely.... Read More
Genetic Variability of Heat Tolerance in Cotton (6 June 2012)
Mankind possesses both the knowledge and the skills required to successfully develop crop varieties that will actually welcome the changed characteristics of the "brave new world" that awaits us... Read More
Climate Change: Back to the Future (6 June 2012)
An older paper by Leith (1975) used a classical concept from statistical mechanics (fluctuation-dissipation theorem) to demonstrate that the response of the climate to external disturbances, even artificial ones, are not different from internal or natural variations. This paper provides the background for the fundamental disagreement in belief between those who are convinced humans now drive the climate from those considered "skeptics". It can then be inferred from the observations of the last century that the science is likely on the side of skeptics... Read More
Landfast Sea Ice Extent Along the East Antarctic Coast (12 June 2012)
Evidence continues to accumulate for the continuing multi-decadal growth of both pack ice and fast ice across the entire East Antarctic region, which is something one would not expect to see in a world experiencing what climate alarmists describe as "unprecedented global warming"... Read More
The Winds of Climate Change: Altering Albatross Life-History Traits (12 June 2012)
What climate change over the Southern Ocean has significantly impacted the wandering albatross? ... and has that change proven helpful or hurtful?... Read More
The Impact of Ocean Acidification and Warming on a Calcifying Predator-Prey Relationship (12 June 2012)
The authors of this paper conclude that "marine communities that are based on calcifying invertebrates may be less affected by warming and acidification than would be expected from species-specific responses to environmental change"... Read More
Sub-Antarctic Sea Urchin Larval Responses to Lower Seawater pH (12 June 2012)
Is the net result more positive or negative? The findings of Catarino et al., as well as those of the other researchers they cite, suggest that "polar and sub-polar sea urchin larvae can show a certain degree of resilience to acidification"... Read More

Anthropogenic CO2 Absorption by the World's Oceans (13 June 2012)
It appears that the global ocean is constantly adjusting its uptake rate of anthropogenic carbon on multi-decadal time scales to continually "keep up" with the rate at which the air's CO2 content rises in response to anthropogenic carbon inputs... Read More
Extreme Droughts in Northeastern Tibetan Plateau (1700-2005) Inferred from Tree-ring Data (13 June 2012)
The multi-year event during the late 1920s and early 1930s was the longest drought in the past 306 years... Read More
Warmth and Peace in the Roman Classical Period (19 June 2012)
Once again evidence continues to accumulate for (1) the rule-of-thumb proposition that warmer times have generally been more peaceful times throughout human history, (2) the likelihood that the high stable temperatures between 60 BC and 90 AD may well have been warmer than those of the 20th century, and (3) the likelihood that solar variability may have been "an important climate forcing factor during this time"...

Fifty Years of Increasing Tree Densities on South African Savannas (19 June 2012)
Buitenwerf et al. say their analysis "has shown significant increase in tree densities and stature that are consistent with global drivers promoting woody thickening." And they conclude that "the only plausible candidate in the experimental areas is increasing CO2 since there were no significant temperature or rainfall trends over the last 50 years."... Read More
The Theory of Warmth-Induced Amplification of Extreme Weather Events (19 June 2012)
What does an unprecedented real-world tree-ring-based hydroclimatic reconstruction of the past millennium for Central Europe suggest about the subject?... Read More

Plant Responses to Significant and Rapid Global Warming (20 June 2012)
In light of most model assessments of the climatic effects of anthropogenic CO2 emissions, many climate alarmists claim that great numbers of plant species will suffer extinction. However, the historical data suggest otherwise... Read More
Dying from Particulate Air Pollution on Hot and Cold Days in Shanghai, China (20 June 2012)
Not only is extreme coldness in and of itself a greater killer of people than extreme warmness, but it would appear from this study and the others it sites that extreme cold also enhances the killing power of the noxious air pollutants PM10 and ozone... Read More
Nitrogen Cycling within Forests Growing in a Warmer World (20 June 2012)
New research shows that "as CO2 concentrations increase and warming stimulates increases in N availability, it is possible that we may see further increases in growth rates of these species." Is this finally the end of the progressive nitrogen limitation hypothesis?... Read More
Earth's Land Surface: Source or Sink of Anthropogenic CO2? (20 June 2012)
Results from the study of Khatiwala et al. indicate that "the terrestrial biosphere was a source of anthropogenic carbon until the 1940s, roughly in line with previous model-based estimates, after which it turned into a sink of anthropogenic CO2"... Read More
Terrestrial "Greening" and "Browning" in Time and Space (26 June 2012)
Instead of destroying nature, the twin evils of the world's climate alarmists - rising atmospheric CO2 concentrations and global warming - have actually fueled the last quarter-century's greening of the Earth... Read More
Land-Use Conflicts in the African Sahel (26 June 2012)
Reflecting on their cause(s), even the IPCC, which "prides itself on being a synthesis of the best peer-reviewed science, has fallen prey to relying on second- or third-hand information with little empirical backing when commenting on the implications of climate change for conflict," because real-world evidence for their climate-change-causes-conflict claim is just not there, at least in the case where the climatic change involves warming...

Update on Remotely-Sensed Antarctic Sea Ice Extent (26 June 2012)
How has it varied over the era of satellite coverage? According to the authors who conducted this study, "southern sea ice has shown modest increases and established new record ice coverage in the summer of 2008 by a wide margin," leading them to wonder just how this "peculiar behavior" meshes with the theory of currently-unprecedented anthropogenic-CO2-induced global warming... Read More
More Phytoplankton Under Arctic Sea Ice than Previously Thought (26 June 2012)
A new study in the Chukchi Sea has found a huge bloom of phytoplankton under first year Arctic sea ice, suggesting that the primary productivity of ice covered continental shelves has been drastically underestimated... Read More
Extreme Weather Heat Waves (26 June 2012)
Although recent model-based studies suggest recent anthropogenic climate warming is the most probable reason for the Russian heat wave of 2010, the fail to adequately explain the proper mechanism for many heat waves of the historic past, which could not have been forced by recent anthropogenic warming of the climate. As a result, any linkage between future heat waves and present climate warming remains questionable at present... Read More
Photosynthetic Responses to Atmospheric CO2 Enrichment in the Long-Term Duke Forest Face Experiment (27 June 2012)
The eight researchers who conducted this study report that the enhancement of light-saturated leaf net photosynthesis in P. taeda trees by elevated CO2 of +200 ppm was 67% for current-year needles in the upper crown of the trees in summer conditions over a ten-year period, while previous-year foliage light-saturated leaf net photosynthesis was enhanced by 30%, with the result that "the mean stimulation in light-saturated leaf net photosynthesis averaged over the growing season of all years and across canopy positions and needle age classes was 53 ± 7%."....

Acidified Seawater: Does It Always Depress Calcification? (27 June 2012)
"Contrary to popular predictions," as the six scientists who conducted this study report, "the deposition of calcium carbonate can be maintained or even increased in acidified seawater." In fact, they say that four of the five species they studied actually exhibited increased levels of calcium in low pH conditions.... Read More
Earth's Thermal Sensitivity to a Doubling of Atmospheric CO2 (27 June 2012)
In the IPCC's Fourth Assessment Report, the most likely range for this thermal sensitivity parameter, as determined by numerous climate models, is something in the range of 2 to 4.5°C; yet this degree of warming may be way too large... Read More
New Model Test Experiments, Same old Results (27 June 2012)
The latest version of Community Climate Model Version 4 was tested for the Coupled Model Intercomparison Project phase 5. It comes as no surprise that with no change in the underlying assumption of anthropogenic greenhouse gas forcing overwhelming natural forcing, the outcome would show a more sensitive climate and a future climate that can only be explained by human activity...
