Skeptical Thoughts on Energy, Science and Global Warming

A Brave New Epoch?

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?

Ocean Conveyor Belt Confounds Climate Science

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.

Climate Science's Dirtiest Secret

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.

Himalayan Glacier Update: Nature Report Misleading

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).

Why Climate Models Lie

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.

Chicxulub Resurgent

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.

Crank of the Week - March 22, 2010 - James Cameron

Fox threw a party for James Cameron and producer Jon Landau to drum up publicity before the pending release of their mega-blockbuster movie, Avatar, on DVD. The gathering of nearly 100 journalists from around the world included a screening of sample video clips from the movie. Not that the people in attendance had never seen Cameron's sexy blue aliens before—the clips were to show the quality of the conversion from big screen 3D to 2D for home consumption. The movie mogul opened the program by pledging an environmental theme to the release of Avatar into the home video market. The video release of Avatar is now set for April 22, which just happens to be Earth Day. And then someone mentioned Glenn Beck.

Econometrics vs Climate Science

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.

Snowballs, Ice Ages and CO2

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.

Presidential Advisor Holdren Replies To Shanahan Energy Letter

On the first of February, 2010, Dr. John A. Shanahan sent a letter regarding the future of American energy policy to Dr. John P. Holdren, Director of the White House Office of Science & Technology Policy and President Obama's Science Advisor. Attached to the letter were more than thirty pages of signatories—309 scientists, engineers and citizens from 22 countries and 36 US states. The purpose of the letter was to ask for a clarification of the Obama administration's stand on nuclear energy policy. Dr. Shanahan's conclusion: if anyone thinks that the current administration's nuclear policy solves America's energy problems, they have no idea what they are talking about.

Cargo Cult Climate Science

Back in 1974, the late Richard Feynman wrote an essay based on the address he gave at Caltech's commencement that year. He titled the essay “Cargo Cult Science,” a reference to the practice of sympathetic magic by South Sea Islanders following World War II. The central point of his lecture was how science should and should not be practiced. His thoughts are well worth reviewing in light of the string of troubling revelations that have surfaced regarding climate science. In the face of what Gallup calls a sharp decline in the public's belief in global warming, it looks like many of the IPCC's scientists are practicing Cargo Cult Climate Science.

Crank of the Week - March 8, 2010 - Lucy Lawless

Best-known for her role as Xena in Xena: Warrior Princess, New Zealand native Lucy Lawless is speaking out about the environment and global warming. Famous for sword play in skimpy outfits, Ms Lawless has no-doubt been the center of many a fan's personal fantasy. Her latest fantasy is saving the planet. In a recent interview the former warrior princess was asked what she would say to those who do not believe in global warming to get them to change their minds. “I think the people running climate change denial campaigns are sociopaths,” Lawless answered. Obviously her persuasive technique has not progressed much beyond the use of sharp edged weapons.

Scientists Admit Global Warming Didn't Kill the Golden Toad

The golden toad of Costa Rica was declared extinct in 1994, five years after it was last sighted in the wild. The unfortunate toad's was the first extinction to be blamed on anthropogenic global warming and it has often been cited as an example of things to come if mankind doesn't change its CO2 spewing ways. But humanity's conviction of toadacide was premature and based on circumstantial evidence. After years of study scientists have a new finding: humans were not at fault after all.

Food Under Fire

Experts predict that, over the long term, food security can't be achieved without energy security. Add in mechanization, storage, and transport and the energy impact of a typical meal in industrialized nations is many times the amount of energy the meal's consumer derives. Recently, researchers have been taking a close look at just how much energy it takes to produce even seemingly similar foods. The conclusion: Food choices can have a significant impact on energy use in agriculture, and by extension, on greenhouse gas emissions as well. Beef lovers beware! As the world diverts more of its grain harvests into meat production, some scientists are taking a closer look at more environmentally friendly sources of protein, including insects.
