    A Melting Arctic: Happy News for Mankind
    Michael Asher (Blog) - September 8, 2008 7:59 AM

    Alarm over sea ice loss is misplaced.

    Recent short-term gains in Arctic ice coverage indicate nothing about the eventual state of the Arctic. Answers to the long-term status of the region lie in the realm of a scientific branch known as paleoclimatology. What does it tell us?

    The Earth is currently in the geologic epoch known as the Holocene. This began nearly 12,000 years ago when the last ice age (more precisely, the Weichsal glacial) ended. Temperatures warmed, glaciers began to retreat, and the Arctic began to melt. This began what is called an interglacial: a warmer period between glaciation.

    We tend to think of the poles as immutable, but geologically speaking, permanent polar ice is a rare phenomenon, comprising less than 10% of history. Icecaps form briefly between interglacials, only to melt as the next one begins -- this time around will be no different.

    So we know the Arctic will eventually be open water. The only question is how it will affect us.

    The language the media uses to describe Arctic melting is usually emotionally loaded. Filled with terms such as "concern", "desperate", even "dying" and "doomed", one would think a living organism was being described. Experts are always quoted as "warning" us, rather than simply speaking -- classic propaganda techniques.

    Even the scientists themselves have an emotional stake in the argument. After all, when you've spent your entire career studying Arctic ice, the possibility of it vanishing is understandably horrifying. But what about the rest of us? Will Arctic melting be good or bad?

    Let's look at the scorecard.

    No change in sea level.
    Arctic ice, which floats rather than being anchored on bedrock, doesn't influence sea levels at all. Antarctica and Greenland do, but with one on a long-term cooling trend, and the other melting at the infinitesimal pace of 0.25% per century, there doesn't seem to be any call for alarm. Sea level has been rising for thousands of years; the increase over the next century is expected to be less than 1/3 meter.

    "Unimaginable" amounts of new resources.
    What's at stake is nothing less than millions of square miles of territory, with some of the richest resources known. 90 billion barrels of oil and 1,700 trillion cubic feet of natural gas lie in the region. An ice-free Arctic also means access to other mineral resources, and access to rich new fishing grounds. Analysts have hesitated to put a figure on the total worth.

    But that's not all. Just the ability to safely navigate the region is itself valuable.

    The Northwest and Northeast Passages
    First navigated in 1905, the famed Northwest Passage allows ships to cross between the Pacific and Atlantic oceans. Currently this requires a trip through the Panama Canal, a lengthy, expensive voyage that is barred to the largest "post-Panamax" class of ships. The permanent opening of the Northwest Passage will shave thousands of miles off each crossing, saving millions of barrels of diesel fuel annually, boosting trade and cutting shipment costs for a wide variety of imported and exported goods.

    Nearly as important, the Northeast Passage is vital for parts of Northern Europe and Russia. First navigated as far back as 1879, a permanent opening will not only reduce shipping costs between Russia and Northern Europe, it will be a boon for thousands of tiny coastal communities that are currently cut off from the outside world for most of each year.

    Though the benefits are unmistakable, a certain segment of the population argues we shouldn't use them. They believe using the planet's resources is immoral, even obscene. But the fact remains that these resources are not just valuable; they're vital. The still-growing populations of China and India are now clamoring for access to the same standard of living the western world enjoys. Granting it to them will require new sources of food, energy, and raw materials.

    Russia has already put its foot in the door, claiming some 460,000 square miles of new territory -- an area larger than France and Germany combined. With its fleet of nuclear-powered icebreakers already surveying, Russia is brushing aside objections over its cavalier acts.

    Some have pointed out that Arctic territorial disputes may lead to conflict, even war. This is possible. But claiming that we shouldn't wish for new resources because we might fight over them is like wishing you won't win the lottery because you and your spouse might argue over how to spend the money. The unlocking of the Arctic's resources is a windfall, no matter how you look at it.

    What about the Polar Bears?
    Recent research indicates that the species is significantly older than first thought, about 120,000 years old. This means polar bears have survived at least one interglacial before, and therefore doesn't depend on permanent polar ice.

    Bears are not the only wildlife in the region. But floating sea ice is not a primary habitat for any species. Many live underneath it, but these are going to benefit dramatically from warmer weather. Higher temperatures equate to more phytoplankton and zooplankton, the base of the pelagic food chain. Measured by total biomass (the sum weight of all living creatures) the northern hemisphere is already seeing increases. That trend should continue.

    While it's not impossible that a few ill-adapted species may go extinct, there is no hard evidence to say it will happen. It's also no cause for alarm. Climate change regularly results in a certain degree of extinction; indeed is an essential factor in the freeing of ecological niches so that new species may arise.

    Feedback Effects
    Sea ice reflects more sunlight than open water. This leads to a positive-feedback effect where decreasing ice leads to further temperature increases. Sounds scary, right? It's not. The reason is a much stronger negative feedback mechanism from basic thermodynamics. The Stefan-Boltzmann law tells us that radiated energy depends on the fourth power of temperature. Put simply, even a tiny increase in temperature results in more heat loss. This explains why past periods in the Earth's history never led to runaway warming.

    Also, the Arctic just doesn't get a lot of sunlight to start with. That's why itís so cold there, after all. What sun it gets is extremely oblique filtered through much more atmosphere due to the high latitude. While Arctic albedo changes do have an effect, it's very small, possibly even immeasurable on a global scale.

    One fact remains without doubt. The warming of the Arctic will not result in our own extinction, or be anything at all but a tremendous boon to mankind and our civilization. Don't let anyone tell you otherwise.

    Interesting article. It is hard to know what to believe since the global warming issue has been so politicized.

    Now that's just the type of level-headed thinking that will get you nowhere on this board. You either have to buy a Prius with the optional hand woven hemp seat covers that you will leave in the garage while you ride a bike or buy a H-1 Hummer with 96" wheels that you use to run down baby squirrels in between fueling up.

    I tell you there is no middle of the road on this issue.

    I agree. I believe that the earth is going through a natural warming trend and doesn't have anything to do with man's use of fossil fuels.

    But, there's no point in pushing our luck either.

    Just because you've safely jogged down the same road for years doesn't mean you won't get hit by a truck.

    I'm all for alternatives for energy, I just don't like the scare tactics of the left.

    Hey, no problem. I thought it was pretty damn interesting, too. Definitely a factual look at the subject, which is certainly something that seems to be needed.

    Alpaca farts do not cause global warming...the fermentation of the gooey green alapaca loogey does however. I believe all Alpaca owners should be held responsible for funding and conducting extensive research into the Alpaca loogey/global warming connection.

    Shortly I will begin lobbying Congress to pass the Alpaca Loogey Tax Act of 2009. Those of us who do not indiscrimently own/harbor the beasts should not be responsible for the mitigation of the alpacas' impact on our environment.

    If anything Alpaca farts could/should be harvested as an alternative energy source, perhaps through a system of pliable tubing that transfers the gaseous by- products of Alpaca chow into a holding tank of sorts or maybe even a trascontinental alpaca fart gasline. Given the more temperate climate, Seen could conceivably harvest the alpaca farts and heat the mud dungeon during the chillier months thus balancing out his beasts' carbon foot print.

    I suggest he immediately contact global warming and energy expert Sarah Palin, (who knows more about energy than anyone in America), for her expertise.

    Lorne Gunter: Thirty years of warmer temperatures go "poof"

    Oops...guess this doesn't exactly fit with the global-warming hysteria crowd...Al Gore, paging Al Gore...

    Lorne Gunter: Thirty years of warmer temperatures go "poof"
    Posted: October 20, 2008, 10:26 AM by Kelly McParland
    Lorne Gunter

    In early September, I began noticing a string of news stories about scientists rejecting the orthodoxy on global warming. Actually, it was more like a string of guest columns and long letters to the editor since it is hard for skeptical scientists to get published in the cabal of climate journals now controlled by the Great Sanhedrin of the environmental movement.

    Still, the number of climate change skeptics is growing rapidly. Because a funny thing is happening to global temperatures -- they're going down, not up.

    On the same day (Sept. 5) that areas of southern Brazil were recording one of their latest winter snowfalls ever and entering what turned out to be their coldest September in a century, Brazilian meteorologist Eugenio Hackbart explained that extreme cold or snowfall events in his country have always been tied to "a negative PDO" or Pacific Decadal Oscillation. Positive PDOs -- El Ninos -- produce above-average temperatures in South America while negative ones -- La Ninas -- produce below average ones.

    Dr. Hackbart also pointed out that periods of solar inactivity known as "solar minimums" magnify cold spells on his continent. So, given that August was the first month since 1913 in which no sunspot activity was recorded -- none -- and during which solar winds were at a 50-year low, he was not surprised that Brazilians were suffering (for them) a brutal cold snap. "This is no coincidence," he said as he scoffed at the notion that manmade carbon emissions had more impact than the sun and oceans on global climate.

    Also in September, American Craig Loehle, a scientist who conducts computer modelling on global climate change, confirmed his earlier findings that the so-called Medieval Warm Period (MWP) of about 1,000 years ago did in fact exist and was even warmer than 20th-century temperatures.

    Prior to the past decade of climate hysteria and Kyoto hype, the MWP was a given in the scientific community. Several hundred studies of tree rings, lake and ocean floor sediment, ice cores and early written records of weather -- even harvest totals and censuses --confirmed that the period from 800 AD to 1300 AD was unusually warm, particularly in Northern Europe.

    But in order to prove the climate scaremongers' claim that 20th-century warming had been dangerous and unprecedented -- a result of human, not natural factors -- the MWP had to be made to disappear. So studies such as Michael Mann's "hockey stick," in which there is no MWP and global temperatures rise gradually until they jump up in the industrial age, have been adopted by the UN as proof that recent climate change necessitates a reordering of human economies and societies.

    Dr. Loehle's work helps end this deception.

    Don Easterbrook, a geologist at Western Washington University, says, "It's practically a slam dunk that we are in for about 30 years of global cooling," as the sun enters a particularly inactive phase. His examination of warming and cooling trends over the past four centuries shows an "almost exact correlation" between climate fluctuations and solar energy received on Earth, while showing almost "no correlation at all with CO2."

    An analytical chemist who works in spectroscopy and atmospheric sensing, Michael J. Myers of Hilton Head, S. C., declared, "Man-made global warming is junk science," explaining that worldwide manmade CO2 emission each year "equals about 0.0168% of the atmosphere's CO2 concentration ... This results in a 0.00064% increase in the absorption of the sun's radiation. This is an insignificantly small number."

    Other international scientists have called the manmade warming theory a "hoax," a "fraud" and simply "not credible."

    While not stooping to such name-calling, weather-satellite scientists David Douglass of the University of Rochester and John Christy of the University of Alabama at Huntsville nonetheless dealt the True Believers a devastating blow last month.

    For nearly 30 years, Professor Christy has been in charge of NASA's eight weather satellites that take more than 300,000 temperature readings daily around the globe. In a paper co-written with Dr. Douglass, he concludes that while manmade emissions may be having a slight impact, "variations in global temperatures since 1978 ... cannot be attributed to carbon dioxide."

    Moreover, while the chart below was not produced by Douglass and Christy, it was produced using their data and it clearly shows that in the past four years -- the period corresponding to reduced solar activity -- all of the rise in global temperatures since 1979 has disappeared.

    It may be that more global warming doubters are surfacing because there just isn't any global warming.
