Water Is Not The New Oil

In the midst of the clamor over global warming, greenhouse gas emissions and world energy supplies another, perhaps more immediate, environmental catastrophe is gathering momentum—the world wide shortage of fresh water. Though eclipsed in America by pictures of oil-soaked pelicans and fouled coastal wetlands, this potentially more disastrous and more permanent problem has been ignored by politicians and the public for decades. Experts are warning that by 2050 fully 45% of humanity may be chronically short of water. Unlike the eventual depletion of the world's oil supplies, there is no substitute for H2O.

Guessing At CO2 Emissions

Supposedly, human activity is responsible for the detected rise in atmospheric CO2 levels over the past century. But do we really know were gas emissions come from and how great they are? As it turns out, greenhouse gas emissions are measured using statistical data without testing the results against the actual increases of these gases in the atmosphere. Regardless, climate change alarmists insist that human emissions must be reduced. A revealing perspective article in the June 4, 2010, issue of Science states “this is like dieting without weighing oneself.” Currently, science is only guessing at where CO2 emissions come from.

Chicxulub Redux: A Lesson In How Science Works

Recently this site posted an article about the extinction event 65.5 million years ago at the end of the Cretaceous period. That extinction coincided 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, published in the March 5, 2010, edition of Science, was cited that summarized what science thinks it knows about the extinction. That article reinforced the single cause asteroid impact extinction scenario. Now, in an excellent example of how the scientific process works, and why scientific consensus is such a bogus term, the May 21 issue of Science has published a number of letters that take exception to the previous article's conclusions.

Kudzu Causes Global Warming!

Across the southeastern US, the nitrogen-fixing legume Pueraria montana, more commonly known as kudzu, has been an impossible to eradicate invader for decades. While its direct impact on native ecosystems is highly visible—a smothering green blanket that swallows up shrubs, trees and even houses—what is not as apparent is kudzu's effect on the atmosphere. Its spread has the potential to raise ozone levels by increasing nitric oxide (NO) emissions from soils by as much as 100%. Since NO is a potent greenhouse gas, the spread of the pesky vine could be a contributing factor to climate change. That's right: kudzu causes global warming!

Climate Science Strikes Back

If a letter appearing in the May 7, 2010, issue of Science is any indication, it looks like climate science traditionalists are trying to stage a comeback. The article by P. H. Gleick and a cast of hundreds, entitled “Climate Change and the Integrity of Science,” states that “we are deeply disturbed by the recent escalation of political assaults on scientists in general and on climate scientists in particular.” Decrying the attacks on climate scientists by “deniers,” the letter reiterates the signatories' support for dogmatic climate change theory. While admitting that the IPCC “quite unexpectedly and normally, made some mistakes,” they call for an end to “McCarthy-like threats” against themselves and their colleagues. Painting themselves as victims, they have gone on the offensive—like the evil Empire of Star Wars fame, climate science is striking back.

Sun & Cycles Heat Up Ice Age Interglacials

Since the Mid-Brunhes Event, around 430,000 years ago, interglacial periods have grown warmer and their CO2 levels higher. Research confirms that Croll and Milankovitch were right: Earth's orbital cycles seem to be the cause of these documented cases of true global warming, with CO2 playing a supporting role, not the lead. Many of the catastrophic events warned of by climate change alarmists turn out to be well within the range of natural variation. Moreover, new findings indicate that the effects of the cycle induced changes, through their impact on the environment in the Southern Hemisphere, are not correctly accounted for in the IPCC models.

Monsoons & Megadroughts

Large portions of the globe rely on the seasonal monsoon for water. Across much of Asia, agriculture depends on the coming of the monsoon rains. One scare tactic employed by global warming extremists is to claim that human caused climate change will keep the monsoon from coming, causing drought, failed crops and famine. In truth, science does not fully understand the complex interactions of ocean, atmosphere, and land that influence the monsoon, or how it impacts climate in other parts of the world. Now, a new Monsoon Asia Drought Atlas (MADA) provides reconstructions of summer moisture for the region going back to 1300 AD. It documents a long sequence of droughts so persistent that scientists call them “megadroughts.” These megadrought events, the worst of which may have toppled ancient kingdoms, show that unreliable monsoon seasons have afflicted mankind throughout history—long before the clamor over climate change arose.

Wind Power: Green and Deadly

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.

Scientists Link Quiet Sun & Cold Winters

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.

Iceland's Ash Cloud May Let Climate Alarmists Off Hook

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.

Missing Heat Hides From Climate Scientists

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.

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.

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.

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.
