Sea Level Response to Global Warming (01 Dec 2010)
There is currently no known way to predict -- with any reasonable and demonstrable degree of confidence -- what mean global sea level will do over the 21st century, even if mean global air temperature begins to rise once again (after having remained rather stable for the past decade)... Read More
Sixty Years of Snow Avalanches in the Northern French Alps (01 Dec 2010)
Authors Eckert et al. (2010) find "no strong modifications in mean avalanche activity or in the number of winters of low or high activity over the last 60 years"... Read More
Increasing Climatic Variability (01 Dec 2010)
What many climate alarmists look upon as unfavorable may actually be just what is needed to (1) enhance the diversity and resilience of myriads of terrestrial and aquatic ecosystems, and (2) propel them to higher levels of activity in the brave new world of our CO2-enriched future... Read More
The Odds of Arctic Lichens Surviving Dramatic Global Warming (01 Dec 2010)
Whatever nature -- or man -- may ultimately be responsible for sending their way in terms of global warming, Arctic-alpine lichens should be good to go ... wherever it is they need to go... Read More

Responses of Scleractinian Corals to Ocean Acidification (01 Dec 2010)
Authors Krief et al. conclude that "scleractinian coral species will be able to acclimate to a high CO2 ocean even if changes in seawater pH are faster and more dramatic than predicted"... Read More
Sun-climate Connection on Millennial Timescales (07 Dec 2010)
The authors provide clear evidence that sunspot activity variations lead tree-ring reconstructed temperature changes from the Northern Lapland, Finland and Norway region by about 70 years covering the Mid to Late Holocene period... Read More

Competition Among Species in a CO2-Enriched World (07 Dec 2010)
The results of a new study suggest that, all else being equal, ecosystem species richness or biodiversity should at least remain stable, or possibly even increase, in response to continued increases in the air's CO2 content... Read More
Grape and Wine Responses to Atmospheric CO2 Enrichment (07 Dec 2010)
Working near Rapolano, Siena (Italy), Bindi et al. conducted a two-year FACE study of 20-year-old grapevines, where they enriched the air about the plants to 550 and 700 ppm (compared to ambient CO2 levels in those two years that averaged 363 ppm, as per Mauna Loa data), measuring numerous plant parameters in the process, including - after the fermentation process was completed - "the principal chemical compounds that determine the basic red wine quality." So what did they find?... Read More
Global Warming and the Intensification of Rainfall Events (07 Dec 2010)
Although a clear correlation between the development of large dams throughout the world and subsequent increases in extreme precipitation was found, the three scientists of this paper state in a cautionary note that "other factors may [also] be involved, such as global climate change." And such could well be true. But one typically doesn't hear the opposite, i.e., climate alarmists acknowledging that increases in extreme precipitation events might partly be induced by something other than global warming....

Droughts of East-Central North America (07 Dec 2010)
Another finding corroborates works indicating that millennial-scale solar-forcing is responsible for droughts and ecosystem changes in central and eastern North America... Read More
Emerging Carbon Sinks of Antarctica (07 Dec 2010)
Peck et al. (2010) write that the loss of glaciers and ice shelves is often thought of as something that "will predominantly increase warming of the earth because of changes in albedo and heat uptake by newly uncovered ground and ocean," but they say that an important opposing effect of this phenomenon "is the opening up of new areas for biological productivity."...

James Hansen's Outlandish "Alpine Plant Extinction Claim" Is Debunked by Real-World Data (08 Dec 2010)

The Atlantic-Arctic Boundary Air Temperature (14 Dec 2010)
U.S. and Icelandic researchers constructed a newly extended temperature history and their analysis of it revealed "an irregular pattern of decadal-scale temperature fluctuations over the past two centuries," of which the early twentieth-century warming (ETCW) event -- which they say "began about 1920 and persisted until mid-century" -- was by far "the most striking historical example"...

The Medieval Warm Period in the Sargasso Sea (14 Dec 2010)
Lloyd Keigwin -- Senior Scientist in Geology and Geophysics at the Woods Hole Oceanographic Institution, Woods Hole, Massachusetts, USA -- introduces his classic paleoclimatic study of the northern Sargasso Sea by stating that "it is important to document natural climate variability in order to understand the effects of anthropogenic forcing," that is to say, in order to correctly determine if the warming of the past several decades is unusual, unnatural or unprecedented in terms of what has occurred in the past. So what did he find in this landmark paper of well over a decade ago?... Read More
Cold-Related Mortality in Europe (15 Dec 2010)
The fourteen authors of this major assessment of cold-weather effects on mortality in Europe report that with respect to short-term exposure to heat and cold, "cold spells lead to excess mortality to a relatively small degree, which lasts for weeks," while "the mortality increase during heat waves is more pronounced, but is followed by lower than average values in subsequent weeks," which suggests, in their words, that people who died from short-term exposure to heat "would have died in the short term anyway"...

A Two-Thousand-Year Temperature History of the Extra-Tropical Northern Hemisphere (15 Dec 2010)
According to the author of this study, "decadal mean temperatures in the extra-tropical Northern Hemisphere seem to have equaled or exceeded the AD 1961-1990 mean temperature level during much of the Roman Warm Period and the Medieval Warm Period," and he says that "the second century, during the Roman Warm Period, is the warmest century during the last two millennia." And there's more... Read More

The Environmental Ethics of Biofuels (15 Dec 2010)
Gomiero et al. (2010) review the wisdom of mankind's proposed appropriation of much of the planet's land and water resources for the purpose of supporting large-scale production of biofuels as replacements for fossil fuels. And in doing so, they come to a number of damning conclusions about the highly-touted enterprise... Read More

Progressive Phosphorus Limitation of CO2-Stimulated Tree Growth (21 Dec 2010)
Khan et al. (2010) say their study "shows that increased tree growth under elevated CO2 has not resulted in depletion of P pools in soils, but rather in replenishment and increased storage of P in the rooting zone," and that contrary to even their own expectations before beginning the experiment, "phosphorus limitation may therefore not reduce tree growth in a high CO2 world."...

Hail Storms in China: Are They Becoming More Extreme? (21 Dec 2010)
The highly-hyped global warming of the past few decades has led to no increase in the extremeness of Chinese hail storms. In fact, the data from this new analysis suggest there was a slight decline in the frequency of such storms, along with a hint of a possible decrease in maximum hail diameter.... Read More

Reality Check: Empirical Trends vs. Global Warming Hype (21 Dec 2010)
A frequent claim of the climate alarmists and the IPCC is that CO2-induced global warming will negatively affect livelihoods and reduce well-being in the developing world. However, decades-long empirical trends of various climate-sensitive parameters related to human well-being suggest otherwise.... Read More

Ocean Acidification and the Sagittal Otoliths of Marine Fish (28 Dec 2010)
A study reveals how the former affects the latter in white sea bass, while we relay what the results imply about the ocean "acidification crisis," which is being pushed to the forefront of the suite of environmental catastrophes that are currently being promoted in the absence of the global warming that was once the centerpiece of Al Gore's "climate crisis"...

Floods of Switzerland Over the Past Five Centuries (29 Dec 2010)
One of the potential negative consequences of global warming about which climate alarmists are very concerned is an increased frequency of flooding; and one way to assess the validity of this concern is to see how flooding around the world has responded to the historical warming of the globe that has occurred since the end of the Little Ice Age, which is the approach that was taken by Schmocker-Fackel and Naef (2010) in their recent study of the subject...
