A New Record of Late Holocene Climate at the Antarctic Peninsula (1 August 2012)
New evidence adds to the already voluminous database that suggests that the Earth has not yet eclipsed the level of global warmth experienced during the MWP, even with the help of all of the anthropogenic-produced CO2 that resides in the atmosphere, which facts cast great doubt upon the climate-alarmist claim that anthropogenic CO2 is the primary cause of Earth's current level of not-so-unprecedented global warmth...

Late-Holocene Climate of the Northeast Atlantic Ocean (1 August 2012)
There would appear to be little need to blame the current high (relatively speaking) atmospheric CO2 concentration for the current low (relatively speaking with respect to the entire 2400-year period examined by the authors of this study) temperature of the northeast Atlantic... Read More
Regional Climate Models: How Well Do They Work? (7 August 2012)
A new study finds there is still a long, long way to go before they are likely to tell us anything of value. Right now, in fact, they could well be considered to be dangerously misleading... Read More

Effects of Elevated CO2 on Coral Calcification: It Makes a Huge Difference Whether the Coral is Dead or Alive! (7 August 2012)
The difference between calcification rates in going from seawater of pH 8.2 to seawater of pH 7.8 ranged from +30% for coral with no dead areas to -21.5% for coral with 30% dead exposed surface area... Read More
Twelve Hundred Years of Winter Surface Air Temperatures in Svalbard and Northern Norway (7 August 2012)
What do they reveal about the warmth of the Medieval Warm Period at the two locations? The 11-year running-mean peak winter temperature of the Medieval Warm Period was approximately 9°C greater than the end-of-record 11-year running-mean peak winter temperature at Longyearbyen, while it was about 3.3°C warmer at Vardo...

Will Storminess Increase in a Warmer World: Models Can't Clear the Skies (7 August 2012)
A new paper by Hernandez-Deckers and von Storch investigates the question of increased storminess in a warmer world using a general circulation model. It has generally been assumed that storminess will increase or decrease due to changes primarily in the equator-to-pole temperature differences. Atmospheric stability has largely been a secondary consideration. The new study demonstrates that, in their model, storminess decreases and atmospheric stability was the larger factor... Read More
Rate of Sea Level Rise: Predictions vs. Measurements (8 August 2012)
According to the author of this study, the huge deceleration of sea level rise (SLR) over the last 10 years "is clearly the opposite of what is being predicted by the models," and that "the SLR's reduction is even more pronounced during the last 5 years"... Read More
Real Climate Change in a Real Greenhouse: Its Impact on Tomatoes (8 August 2012)
The ingenuity of man proves to be of great value in this real-world demonstration of manmade "climate change" within a greenhouse... Read More

Polar Bears May Have Survived 4-5 million Years of Climate Change (8 August 2012)
A new genetic study suggests polar bears arose between 4-5 million years ago and thus survived the more than 50 glacial/interglacial cycles of the Pleistocene... Read More
Tropical Influences on North Pacific Sea Surface Temperatures (14 August 2012)
Tropical Pacific forcing associated with ENSO and North Pacific SST variability associated with the PDO are not well represented in state-of-the-art global climate models... Read More
Effects of Nighttime Warming on the Reproduction of Lizards (14 August 2012)
Do the consequences of enhanced nocturnal warmth hinder or help lizards to reproduce? According to the authors of this study, such effects are "primarily beneficial for this population of northern lizards," and they predict that "future changes will continue to benefit the reproduction, growth and survival of individuals at this site"...

Caribbean Corals: What's Really Been Giving Them a Hard Time? (14 August 2012)
Contrary to climate alarmist claims, it's not global warming!... Read More
Effects of Low pH on Early Life Stages of Atlantic Herring (14 August 2012)
In contrast to what is so often assumed, after performing a series of experiments the authors of this study conclude that "herring eggs can cope at current temperature conditions with an increase in CO2," even one "exceeding future predictions of CO2-driven ocean acidification"... Read More
Convective Clouds Continue to Confound a GCM (14 August 2012)
Stratton and Stirling (2012) unveil a method for improving the timing and strength of convection as it relates to the diurnal cycle. The aspect ratio of convective clouds is correlated to physical properties and processes, and the improvement to model performance here was noteworthy. The new scheme also improves the climatological representation of precipitation in general. But, improvement was not universal, and there are still large differences between the model climate and observations... Read More
The Hydroclimate of the Upper North Saskatchewan River Basin (15 August 2012)
A new streamflow reconstruction provides a whole new-and-improved basis for determining the "uniqueness" of whatever future droughts might occur throughout the region, making it much more difficult for climate alarmists to claim that such droughts were caused by anthropogenic CO2 emissions, since there was far less CO2 in Earth's atmosphere prior to the 1912 start-date of the region's prior streamflow history, when several way more serious droughts than those of the past century are now known to have occurred...

How is the struggle between the two impacted by rising atmospheric CO2 concentrations?... Read More
The Coral Atoll Islands of the Chagos Archipelago (15 August 2012)
Prior research indicated that relative sea level had risen on the islands at a rate as high as 5.44 mm/year. However, the three researchers who conducted this analysis report that "there is no evidence of any statistically significant sea-level rise either from the Diego Garcia tide gauge (1988-2000 and 2003-2011) or in the satellite altimetry record (1993-2011)"...

Effects of Atmospheric CO2 Enrichment on Early Root Growth of Tomato Plants (15 August 2012)
here's nothing like a substantial increase in the air's CO2 content to get a plant off to a good start at life, and to truly excel in the never-ending struggle to extract from the soil what it needs to fulfill its true genetic potential... Read More
Plant Diversities on Sixty-Six Warming European Mountaintops (21 August 2012)
Although mountaintop warming throughout all of Europe between 2001 and 2008 did indeed lead to upward migrations of several plant species, those at the tops of the mountains were not "pushed off the planet" as climate alarmists are wont to claim... Read More
Acidification Effects on Deep-Sea Corals and Other Megabenthos (21 August 2012)
Would you believe they are almost nil? Indeed, the five researchers who conducted this study say they "found little evidence that carbonate under-saturation to at least -30% affected the distribution, skeletal composition, or growth rates of corals and other megabenthos"... Read More
Winter Snow Accumulation in the Andes of Chile and Argentina (21 August 2012)
There has been nothing unusual, unnatural or unprecedented about winter snow accumulation in the Andes of Chile and Argentina over the past few decades, when the world's climate alarmists claim the Earth warmed to a degree and at a rate that they describe as unprecedented over the past millennium or two...

The Roman Warm Period in Southwest Scotland (21 August 2012)
Once again we have another manifestation of the fact that in numerous places around the world, it was just as warm - or warmer - some two millennia ago than it has been recently, when there was 30% less CO2 in the air than there is today. And this observation strongly suggests that the warmth of today is likely due to something other than mankind's CO2 emissions... Read More
The South Pacific Convergence Zone: A Real "Swinger" Under the Influence of CO2? (21 August 2012)
A letter to Nature from Cai et al. (2012) demonstrates that the South Pacific Convergence Zone (SPCZ) will be stronger and thus more frequently take on a more clear zonal orientation in a future climate where CO2 concentrations increase dramatically. This result occurs in spite of a weaker increase in El Niño occurrence, which has been linked to SPCZ strength and location. This implies stronger variability in the precipitation for the ecosystem of the southwest Pacific... Read More

After conducting a series of laboratory experiments the authors of this paper conclude that "it is unlikely" that the plankton community they studied would be significantly affected by oceanic pH changes expected over the next century... Read More
Do Regional Climate Models Realistically Represent Precipitation? (28 August 2012)
A new study of precipitation variability and extremes over Portugal gives one pause for thought as the authors of this study state in their concluding paragraph, "the present results suggest that there is still some way to go in this research"... Read More
Can Bioenergy from Forest Products Significantly and Sustainably Reduce Fossil Fuel Use? (29 August 2012)
