An average US citizen or corporate entity who kills an endangered animal can be in big trouble with the law. Birds, eagles in particular, are zealously protected by nature lovers in America and around the world. Yet a July 2008 study of the wind farm at Altamont Pass, California, estimated that an average of 80 golden eagles were killed there by wind turbines each year. The study, funded by the Alameda County Community Development Agency, estimated that about 10,000 other protected birds were being killed along with the eagles every year at Altamont. Where is the outrage over this slaughter? It would seem ecologists have a blind spot when it comes to the wind energy industry. As a result, the carnage caused by wind turbines, the “Cuisinarts of the Air,” is getting greenwashed. And birds are not the only creatures wind turbines kill—they kill bats and people as well.
Asking the somewhat obvious question, “are cold winters in Europe associated with low solar activity?” a group of scientists have announced that the answer is yes. While this may seem unsurprising, the finding is another indication that Earth's climate is not simply driven by greenhouse gas emissions. Even so, some scientists are only grudgingly accepting the finding, cautioning that this only applies in the central UK and refusing to admit that the Sun could affect global mean temperatures as well. Still, the researchers found that average solar activity has declined rapidly since 1985 and cosmogenic isotopes suggest a possible return to Maunder minimum conditions within the next 50 years. This could be a sign that climate science is starting to recover from its CO2 fixation.
March 20, the Eyjafjallajökull volcano began erupting after slumbering for almost 190 years. The eruption also brought a threat of floods and earthquakes, while the resulting plume of volcanic ash shutdown the European airline industry, costing an estimated $200 million a day. In the short-term, the volcano has been bad for Northern Europe and given a boost to Iceland's tourist industry, but there are larger questions involved. With tedious predictability, a number of climate change alarmists quickly claimed that the volcano was caused by global warming. A more likely outcome is a cool Northern Hemisphere summer caused by airborne ash—which could give the alarmists an excuse for the continued lack of global temperature rise.
The wind is notably capricious, varying in strength and direction in seemingly random ways. The output of wind turbines, which capture the energy of the wind and turn it into electrical power, also varies unpredictably. Leveling out these fluctuations is the biggest obstacle to wind power serving as an effective alternative to conventional power sources. A study, just published in PNAS Online, claims that wiring together offshore wind farms, from along the entire length of the US East Coast, could provide a steady power source for the area. This has led to proclamations by a number of green power advocates that America's energy problems can be solved by wind power. Unfortunately, steady to a scientist is not the same as steady to a power grid engineer, or consumers.
Climate scientists have decided that as much as half of the heat energy, believed to have built up on Earth in recent years, is hiding somewhere it can not be found. By measuring the radiative energy input at the top of Earth's atmosphere, scientists have a pretty good idea of how much energy is entering the planetary environment—the problem is figuring out where it goes. The most likely place is in the deep ocean, whose waters form a huge potential storage place for heat. Because energy is exchanged between the atmosphere and the ocean, this heat can resurface at a later time to affect weather and climate on a global scale. It has been suggest that last year’s rapidly occurring El Niño may be one way the “missing” solar energy has reappeared—the implication being more sudden El Niño events may be on the way.
The current hot buzzword in Information Technology (IT) circles is “cloud computing,” the concept of a shared grid of computer resources, made available to a wide range of consumers in an on-demand, self-service and pay-as-you-go fashion. Even those not immersed in the arcane details of IT are aware of the latest must have techno-doodad from Apple Computer—the iPad. Proving that they can find a dark cloud to go with any silver lining, the perennial eco-pessimists from Greenpeace have declared that the combination of iPads and cloud computing are going to greatly accelerate mankind's march to a planet frying future.
Once again, scientists propose that planet Earth has been so altered by human activity that we are entering a new geological time period—the Anthropocene. A viewpoint article by some stratigraphic heavy hitters, just published in the journal Environmental Science & Technology, has proclaimed a new age caused by anthropogenic global warming and man's savaging of the environment. According to these experts, the effects of human activity have become so pervasive that Earth has been transformed and the 11,000 year old Holocene epoch is now a “lost world.” Is this really the start of a brave new epoch, one of our own making?
The Atlantic Meridional Overturning Circulation (AMOC), also known as the “Ocean Conveyor Belt,” has been the subject of much study since its discovery. The AMOC is primarily responsible for Europe's temperate climate and some scientists have warned that global warming could cause the ocean's flow to slow down or even stop. This rather counter intuitive result of a warming climate would result in a much colder Europe—perhaps even a new mini-ice age. A new analysis of data from satellites and drifting sensors finds no evidence that the conveyor belt is slowing. In fact, a NASA backed study indicates that the conveyor is far less susceptible to throttling by climate change than some climate change alarmists feared.
With the climate science party-line case for global warming rapidly unwinding there is growing interest by researchers from outside the climate change community in applying advanced statistical techniques to climate data. It has long been recognized that statistical acumen is lacking among mainstream climate scientists. This dirty little secret was first publicly disclosed during Congressional hearings regarding the 2006 Wegman Report. Even newer analyses have revealed that many of the predictions made by the IPCC reports and other global warming boosters are wrong, often because inappropriate statistical techniques were applied.
There is a new report in the journal Nature that some climate change alarmists are saying repudiates criticisms leveled at the IPCC over the Glaciergate scandal. In the “news feature,” a reporter looks at the “clues” scientists have found regarding the fate of the Himalayan glaciers from ground- and space-based studies. Though the scientists quoted clearly state they do not have enough data to draw meaningful conclusions—only 15 of 20,000 glaciers were examined on-site—the article still misleadingly says the glaciers are in trouble. It still had to admit the Himalayan glaciers won't vanish by 2035 and that they are not receding faster than glaciers in any other part of the world, both claims made previously by the Intergovernmental Panel on Climate Change (IPCC).
It has come to light that a number of climate scientists have been less than truthful with regard to climate data. As shocking and embarrassing as this has been to the scientific community, it serves only to emphasize the huge blind spot that scientists have for their computer models. It is a career ending offense to knowingly falsify data, yet the entire climate science community engages in even worse deception without a second thought. This is because lies are generated for them wholesale by their faithful yet duplicitous servants: computer climate models.
Although the story of the “Asteroid that killed the Dinosaurs” has become common knowledge for most people, there are still those scientists who back alternative causes of the end Cretaceous extinction even. Volcanoes, multiple meteor strikes and even widespread forest fires have been suggested as the cause of the dinosaurs' demise. The extinction event 65.5 million years ago did coincide with a large asteroid impact at Chicxulub, Mexico, and occurred within the time of Deccan flood basalt volcanism in India. A new review article by 41 scientists in the March 5 edition of Science runs down the list of what science thinks it knows about the extinction that set the stage for the age of mammals.
Recently, a number of papers have surfaced that use advanced statistical methods to analyze climate data. The techniques involved have been developed not by climate scientists but by economists and social scientists. These new tools belong to the field of econometrics. The use of statistical break tests and polynomial cointegration to analyze the relationships between time series data for greenhouse gas concentrations, insolation, aerosol levels and temperature have shown that these data are non-stationary. The implication of these findings is that much of the statistical analysis applied by climate scientists is flawed and potentially misleading. So strong is the statistical evidence that a couple of economists are claiming to have refuted the theory of anthropogenic global warming. This, on top of everything else that has recently transpired, may indicate that a climate change paradigm shift is imminent.

Earth's climate history includes numerous incidents of rapid warming and cooling. While Pleistocene ice-age glacial terminations are arguably the most dramatic recent examples of sudden climate change, during the last glacial period the climate of the Northern Hemisphere experienced several other significant episodes when the climate rapidly warmed. Scientists call these episodes Dansgaard-Oeschger (DO) events after the Danish and Swiss researchers who documented them using ice-core studies. These rapid oscillations are marked by rapid warming, followed by slower cooling. The most prominent coolings are associated with massive iceberg discharge into the North Atlantic Ocean known as Heinrich events (HE). The melting icebergs add large volumes of cold fresh water to the ocean, disrupting circulation patterns and causing further climate changes. Scientists look to past events like these to help us understand how Earth's climate system functions—what causes our planet to cool or suddenly warm. Recently, new data on past climate changes have led one commentator to predict the end of winter skiing in the American Southwest.
