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!
Many climate change alarmists have predicted a wide range of calamitous side-effects to be caused by global warming. One such link that frequently surfaces is that global warming will cause the spread of malaria, leading to a world wide pandemic. A new study, just published in the journal Nature, has shown that malaria is actually declining worldwide. Furthermore, proposed future climate induced effects are insignificant compared with the observed natural trend and easily overcome by current disease control mechanisms. In short, claiming that malaria will spread around the globe due to climate change is an outright lie.
There has been much wailing and gnashing of teeth over the Deepwater Horizon disaster in the Gulf of Mexico. This unprecedented accident for the American offshore drilling industry, the first significant spill in 40 years, will certainly have a calamitous impact on the Gulf marine environment and surrounding coastal areas. What is less certain, but potentially even more dangerous, is the effect that this spill will have on the US domestic oil industry. While environmentalists clamor for a shut down of all offshore drilling in the Gulf, realists know that this will make the threat to ocean life even greater. What has not being told to the public is that nature itself leaks more oil into the ocean each year than mankind, and has been doing so for millions of years. What is even less known is that offshore drilling can actually reduce the amount of crude released into the seas.
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.
There is little doubt that the political forces promoting climate change hysteria are under attack and in retreat around the world. It has also become obvious that little global consensus exists among climate scientists regarding how to regain the public's trust. There is, however, ample evidence that the climate change alarmists have not learned their lesson. At a recent conference held in Washington, D.C., an eminent climate policy expert urged that scientists and policy leaders embrace the persuasive power of uncertainty. If you cannot convince the public with the facts, frighten them into going along anyway seems to be the message. This is not science, it is subterfuge justified by blind faith.
After some last minute tweaking to overcome concerns raised by the recent oil spill in the Gulf of Mexico, the American Power Act, a bill proposing a Cap & Trade system for reducing US carbon dioxide emissions, was introduced in the Senate by John Kerry, a Massachusetts Democrat, and Joe Lieberman, a Connecticut Independent. Notable by his absence was South Carolina Republican Lindsay Graham, who came to his senses just in time to back out of the bill writing troika. Purportedly, the bill aims to reduce emissions by 17% by 2020 and by over 80% in 2050. What it really does is levy a stealth tax on carbon based energy, hiding it behind a “carbon trading” market scheme that would have made Enron proud.
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.
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.
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.
Michael Mann, the Penn State meteorology professor and global warming true believer, best known for his invention of the “hockey stick” temperature graph, is mad as hell and not going to take it any more. The globe may not be warming, but things are evidently getting too hot for Dr. Mann. After enduring university investigations, hostile questioning, legislative probes and attacks by colleagues he has had enough and is threatening to sue the makers of a satirical video that's a hit on You Tube. Look out—like mobsters on The Sopranos, the Climategate Mafia is lawyering up.
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.
