Ocean CO2 Storage Revised

The ocean is Earth's largest single sink for CO2 outside of the planet's crust itself. Simple sea creatures depend on carbon dissolved in the ocean's water for their existence, and their actions create a biological carbon “pump” that removes vast quantities of CO2 from the atmosphere. Large amounts are suspended in the water column as dissolved organic carbon (DOC), and each year the ocean's biological pump deposits some 300 million tons of carbon in the deep ocean sink. New findings have revealed that massive amounts of carbon are converted into “inedible” forms of organic carbon that remain out of circulation for thousands of years, effectively sequestering the carbon by removing it from the ocean food chain. According to Jiao Nianzhi, a microbial ecologist here at Xiamen University, the amount stored is tremendous: “It's really huge. It's comparable to all the carbon dioxide in the air.”

Ocean Conveyor Belt Dismissed

After nearly 50 years of acceptance, the theory that a great ocean “conveyor belt” continuously circulates water around the globe in an orderly fashion has been dismissed by a leading oceanographer. According to a review article in the journal Science, a number of studies conducted over the past few years have challenged this paradigm. Oceanographers have discovered the vital role of ocean eddy currents and the wind in establishing the structure and variability of the ocean’s overturning. In light of these new discoveries, the demise of the conveyor belt model has been become the new majority opinion among the world's oceanographers. According to M. Susan Lozier, of Duke University, “the conveyor-belt model no longer serves the community well.”

Polar Sunlight Drives Climate Change

Around 3 million years ago, Earth's climate started growing colder. Glaciers began forming in high northern latitudes, while surface waters cooled in parts of the equatorial Atlantic and Pacific Oceans. At the same time, climate sensitivity to variation in the tilt of Earth's axis—called obliquity—increased substantially. Since that time, changes in sunlight associated with obliquity have caused variation in global ice volume and equatorial sea surface temperatures (SST). Inexplicably, variations at the equator occurred a few thousand years before those in high latitudes and thus could not have been a direct consequence of the waxing and waning of glaciers. Two new papers in the June 18, 2010, issue of Science attempt to explain the true causes of climate change.

PNAS Climate Change Expert Credibility Farce

A new, purportedly scientific report in the Proceedings of the National Academy of Sciences (PNAS) is claiming that more “top” environmental scientists believe in global warming. Moreover, the report also claims that the scientists who do believe in global warming—now re-labeled anthropogenic climate change (ACC)—have higher credibility than those who do not. All of this is based on an “extensive dataset of 1,372 climate researchers and their publication and citation data.” Citing such data is like saying “most of the people who write for conservative magazines are conservatives.” In other words, the study is devoid of factual significance and possibly purposely misleading. More propaganda from the sinking global warming ship.

America's Atomic Folly

American politicians are falling over themselves to enact new energy legislation before the Gulf oil leak gets plugged. The sad fact is, the US is dragging its feet on the one proven source of reliable, emissions free power: nuclear energy. With some environmentalists likening the oil disaster to Three Mile Island—the nuclear accident that destroyed the US atomic energy industry—the Obama administration has given nuclear power little more than lip service in recent months. Now comes news that a New Mexico-based company that is doing pioneering work in miniature atomic power plants has signed a deal to manufacture small, modular nuclear reactors in China. Political indecision and agitation by green activists is once again conspiring to turn the US into a second rate technological nation.

Agriculture Reduces Greenhouse Gases

Often a target for environmentalists and global warming alarmists alike, intensive modern agriculture has been demonized as the cause of many types of pollution, including those dreaded greenhouse gases. A study, soon to appear in the Proceedings of the National Academy of Sciences (PNAS), reveals that highly productive modern agriculture actually reduces net greenhouse gas emissions when compared with using croplands less intensively. Furthermore, expansion of agriculture, needed to feed mankind's ever growing numbers, can help reduce future increases in CO2 emissions. Looks like the doomsayers got it backwards again, more intensive agricultural is a good thing for the environment. In fact, agriculture reduced total human carbon emissions from 1850 to 2005 by 34%.

Clean Coal & Biofuels Will Cause Water Shortages

With the oil disaster in the Gulf of Mexico emboldening all the denizens of the eco-underground, some voices are once again calling for increased production of biofuels—ethanol and biodiesel—and accelerated research into clean coal. Ignoring the fact that biofuels take as much energy to produce as they provide and that they are only competitive with heavy government subsidies, biofuel boosters are again trying to sell their snake-oil to the public. But the single most damning aspect of biofuel production is the exorbitant amount of water it takes to cook-up a gallon of the stuff. Now it appears that the other great energy scam, clean coal, will also increase water usage—by a whopping 80%. With the world facing a real water crisis in the near future, the last thing any government should be doing is wasting their citizens' money on are “green” energy scams that are really just subsidies for coal companies and big agribusiness conglomerates.

Soil Fungus Soaks Up CO2

There have been arguments made for increased plant growth due to rising atmospheric CO2 levels, while others have argued against it. Now it seems that green plants and ocean algae are not the only forms of life involved. Opportunistic microorganisms are stepping in to sop up excess carbon. A new report in the Proceedings of the National Academy of Sciences (PNAS) has identified soil fungi as a major player in accelerating CO2 absorption. Arbuscular mycorrhizal fungi (AMF) have been identified as an intermediary between plants and other bacterial and fungal populations, acting as a buffer for other soil-borne communities. Existing organisms are not just working harder, new communities are developing to take advantage of increased CO2 levels, demonstrating that nature possesses self-regulation mechanisms science did not anticipate and has yet to discover.

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 Change-Malaria Link Debunked

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.

Crude Facts About Offshore Drilling

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.

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.
