ANOTHER CRITIQUE OF THE LATEST ARCTIC SCARE

"The Arctic Climate Impact Assessment, despite its recent release, has already generated analysis pointing out numerous flaws and distortions. Widely accepted data records show Arctic temperatures that are roughly the same as in the 1930s and part of a slight cooling trend over the last few thousands years, and that the Greenland ice sheet is also cooling, all in opposition to the unsourced data sets contained in the Assessment.

Launching the Counteroffensive takes on the misleading Arctic scenarios: "As for the Arctic Sea, satellite photos show that ice cover has contracted since 1979, a period when the region warmed. However, the Arctic has not warmed faster than the rest of the Northern Hemisphere, contrary to what we would expect if the polar warming were due to an intensification of the greenhouse effect," writes Lewis. "Moreover, the Arctic was warmer during the late 1930s and early 1940s, before the rapid rise in CO2 levels, than it is today. For all we know-satellite photography did not exist 65 years ago-the Arctic then looked pretty much as it does now."

In order to generate the predictions of massive dislocation and disaster in the Arctic, the authors of the Impact Assessment had to use warming scenarios from a previous report - the Intergovernmental Panel on Climate Change's Third Assessment Report - which scientists and economists consider extreme and among the least likely to actually come to pass. Even the evidence for one of its most widely cited predictions, that polar bears may become extinct due to regional warming, is actually consistent with a larger population of bears competing for a naturally limited food supply.

THE FREE MARKET IMPROVES FUEL ECONOMY WITH NITROGEN

The gas mileage gains for properly inflated tires may be more significant that you would think. Some state and federal studies have shown that motorists often are driving with tires 8 to 18 pounds under proper inflation pressure. One study showed that in a car running with tires at 24 pounds per square inch (psi), increasing tire pressure to 32 psi increased gas mileage by 3 miles a gallon. At today's prices that's pretty good. Although, as I have mentioned, I'm a little recalcitrant, I do try to keep my tires inflated to the maximum pressure listed on the tire (you'll see it in raised numbers somewhere on the sidewall of your tires).

Expert drivers in fuel economy runs have always known this and they superinflate their tires, running at 100 pounds per square inch or more. Don't do this! It's mucho dangerous. These guys are usually using special tires under special conditions. Just follow the "max pressure" readings on your tires and, more important, keep checking them. And here's something that can help you. An old technological fix, known to the experts but not very well known to the public, can keep your tires running for long periods at ideal pressure.

It's nitrogen. Yep. Good old nitrogen -- that unglamorous inert gas that constitutes about 78 percent of the air we breathe. For years, over the road truckers, auto racers and the U.S. military have been filling tires on their vehicles with pure nitrogen. Here's why. In a tire filled with compressed air, the oxygen molecules tend to "migrate" through the wall of the tire over time. That's why, when you open the garage to check on your aunt's dust-covered 1980 Pontiac the tires are often flat. But nitrogen molecules migrate 3 to 4 times more slowly than oxygen, so tires stay properly inflated longer. There are other benefits. Nitrogen retains less heat than oxygen and therefore allows tires to run cooler.

While nitrogen is dry and benign and will not combine chemically with other materials (the metal in tire rims, for instance), compressed air contains trace amounts of water and the oxygen tends to combine with other materials, causing rust and corrosion. If you were to see the inner face (the part enclosing and sealing the inside of the tire) of some fancy aluminum wheels you would be surprised at how corroded they become due to oxidation.

Tour de France bicyclists fill their tires with nitrogen. So do NASCAR, Indy and Formula One racing teams, over-the-road truckers, some fire departments and the U.S. military.

And now, in a typical example of the confluence of technology and markets, high gasoline prices and continuing concerns about tire safety are bringing about a growing interest in nitrogen. Big discounter Costco has begun offering nitrogen fill-ups on new tires in some of its tire centers. Pep Boys has been test marketing nitro at some of its tire shops in the south. Several small tire chains in Florida, New York and Ohio are doing the same.

Branick Industries, of Fargo, N.D., one of the nation's leading suppliers of equipment for tire, wheel and suspension services, builds a nitrogen inflation system that takes air from a garage or service center's air compressor and passes it through an internal membrane that separates out the abundant nitrogen molecules. The pure nitrogen is compressed and stored in this "nitrogen generator" and or a back-up tank next to it, from which tires are filled. Costco is filling new tires with nitrogen for free. Some dealers charge $2 per tire and up to $5 apiece on tires not sold by them.

It's a safe bet you'll be hearing more about nitro and seeing an increased availability of nitrogen fill-ups as you shop for tires or maintain your present ones. In the greater scheme of things this is no big deal. But like the improvements that have been made in the inner workings of automatic transmissions over the past 50 years it is one of those gains in efficiency that we often take for granted. It is one of those little refinements and improvements that are routine in a vigorous, free and therefore infinitely articulate market.

USING THE LAW CONSTRUCTIVELY

A conservative legal group has threatened to sue the federal government over its plans to protect four dozen endangered species in California ranging from peninsular bighorn sheep to the tiny robust spineflower. The Pacific Legal Foundation notified the U.S. Fish and Wildlife Service and National Marine Fisheries Service on Monday that it would file suit in 60 days, claiming the agencies failed to meet requirements of the Endangered Species Act when they set out to protect 16 animal and 32 plant species. Advance notice is required before filing endangered species lawsuits.

Based on a favorable ruling in U.S. District Court in Fresno that overturned habitat protection for the Alameda whipsnake last year, the foundation said the agencies underestimated the economic impact of protection and didn't properly follow the rules to protect habitat. "They speculated instead of determining what areas are essential to the conservation of the species," said attorney Reed Hopper.

The legal foundation, representing business groups, farmers and developers in the case, said its lawsuit would ultimately bring back jeopardized plants and animals, a claim dismissed by environmentalists. "Only the Pacific Legal Foundation is cynical enough to argue that taking away habitat protection will help endangered species," said Kieran Suckling, of the Center for Biological Diversity, which has appealed the whipsnake case. "This lawsuit is all about paving California and clearing the way for massive development."

Under the Endangered Species Act, the federal government is required to map out land that is essential to a plant or animal's survival and recovery. The so-called critical habitat designation has been a hot topic for business interests, environmentalists and the federal government. Environmentalists have sued to force the government to identify habitat to protect species while developers and farmers have sued to remove or alter the designation, which can crimp logging, mining and large-scale development projects.

The government, meanwhile, has said habitat designation pales in comparison to the protection afforded once a species is listed as endangered or threatened. The Fish and Wildlife Service has blamed litigation for creating a backlog of petitions to protect other species and for diverting funds that could be used for other protection efforts. "We could put more resources into recovery if we didn't have to spend those resources on critical habitat," said spokesman Al Donner.

Many people would like to be kind to others so Leftists exploit that with their nonsense about equality. Most people want a clean, green environment so Greenies exploit that by inventing all sorts of far-fetched threats to the environment. But for both, the real motive is to promote themselves as wiser and better than everyone else, truth regardless.
