Forget Global Warming, Prepare for an Ice Age

Despite the howls of environmentalists that we are about to be destroyed by the global warming that caused Katrina, Rita and the rest of the twenty-six hurricanes this year, the Earth is headed for another deep freeze, according to the conclusions of Robert W. Felix in his new book "Not by Fire, But by Ice." Felix believes there is evidence that vast, underwater volcanic warming of the earth's oceans will bring about the next ice age because as the oceans warm, evaporation increases leading to more precipitation. As the rain increasingly falls as snow, a new ice age will begin. Other scientists believe the current cycle of ice ages was triggered when the tectonic plate carrying the India subcontinent crashed into Asia. Or, other climatologists believe, there is a relationship between sunspot activity and climate change. There is no such thing as "normal" weather. The Medieval Optimum lasted from A.D. 900 to A. D. 1300; a period in which agriculture flourished and human populations increased. That period was followed in 1350 by the Little Ice Age that lasted until the middle of the Nineteenth Century. It used to be that people blamed seemingly unusual weather "on devils or demons; now we blame Big Oil and the family mini-van," Felix stated.

GLOBAL WARMING

Thursday, December 01, 2005

Though alarmists argue that ferocious hurricanes and increasing temperatures are symptoms of man-made global warming, author Robert W. Felix, in his book, "Not by Fire, But by Ice: The Next Ice Age Now," predicts the earth will be hit with another ice age before the polar ice caps melt.

Consider the facts:

  • The earth gained about one degree Fahrenheit between 1850 and 1940, but it was even warmer millions of years ago than it is now, and it is not showing signs of significant warming.
  • The Ice Shelf in Greenland and the Antarctic is not melting away; it's actually getting thicker.
  • The earth has been in an interglacial period between ice ages, lasting about 11,000 years, so we are due for another ice age soon.

According to Felix, warming oceans lead to increasing evaporation, resulting in more precipitation and more snow, which will usher in a new ice age.

Furthermore, he explains, mass extinctions of animal and humankind have been the rule, not the exception, for the past 3.5 billion years.

Global Warming Is Real, So Get Over It

by Richard Lessner
Posted Dec 5, 2005


Global warming is a reality. It's an observable, measurable, empirical, scientific fact. Let's all say it together: "Prince Charles, Ted Turner, Al Gore -- you're all right! The climate is getting hotter."

Yes, the Earth is warming, but human activity has nothing to do with it. The Earth's climate has been growing warmer since the end of the last Ice Age, around 10,000 years ago, long before the internal combustion engine, Exxon, SUVs, Halliburton, Democrat congressmen, or other alleged human sources of so-called greenhouse gasses.

The problem with the global warming fear-mongers is their utter lack of historical or geophysical perspective. They're not unlike Charlie Brown's sister Sally, who opened a Sunday school essay: "In Church History, it's important to start at the beginning. Our pastor was born in . . ." For the global warming crowd, the history of the Earth's climate apparently began the day they were born and any deviation from their lifetime's experienced "norm" is met with arm-waving, garment-rending, hair-on-fire hysterics. Every hurricane, heat wave, drought, or snow storm is loudly boomed as nature lashing out and striking back at industrial society.

When the climate doomsayers point to North America's receding glaciers, for example, as evidence of human-induced global warming, they conveniently neglect to observe that 12,000 years ago everything from Wisconsin and Massachusetts north to the pole was covered by a mile-thick sheet of ice. Canada was one vast hockey rink. The retreat of the ice sheet opened a corridor for Siberians to migrate into North America by walking across the Bering land bridge. As the ice caps melted due to global warming the ocean level rose hundreds of feet. Vast coastal areas disappeared under rising seas, submerging the land bridge beneath the Bering Sea and cutting off Asia from America, along with its human and animal populations.

Where once polar bears frolicked in what today is central Illinois, the bruins now have skedaddled along with the glacial ice sheets to Hudson's Bay. Was this a disaster for the bears? Hardly. It's all part of the normal climatic cycle of global warming and cooling that has been taking place for several million years. Animals and humans long since have learned to adapt to such climate changes, some of which occurred with startling rapidity. The onset of an Ice Age can occur in as short a span as a few decades, and periods of warming can unfold just as suddenly. So an increase of a degree or two over a century, as the meeting of the climatically challenged in Montreal this week predict, is scarcely cause for panic.

Among scientists it's hotly debated why about 3 million years ago the Earth suddenly entered into an extended cycle of advancing and retreating Ice Ages each lasting from 40,000 to100,000 years. By contrast, during the 100 million year-long Age of the Dinosaurs, the planet was very much warmer than it is today. While T Rex roamed present-day Montana looking for a tasty Hadrosaurus to dine on, the Earth had no polar ice caps at all.

Some scientists now believe the current cycle of Ice Ages was triggered when the tectonic plate carrying the India subcontinent crashed into Asia, thrusting up the Himalayas and disturbing the global air currents that control the weather. Other climatologists have detected a relationship between the relative brightness of the sun and Earth's climate. The sun goes through lengthy cycles of sunspot activity, and the changing amount of solar radiation reaching our planet has an enormous influence on climate, many times greater than any imaginable human industrial activity. Moreover, our entire solar system oscillates up and down, above and below the plane of the Milky Way, over a period of 600,000 years in a galactic waltz that may influence the global climate. Volcanic eruptions also dramatically alter Earth's climate. A single large eruption can lower the global temperature by several degrees. The 1815 eruption of Tambora in Indonesia produced "a year without summer." Some really huge eruptions have been big enough to spark a new Ice Age.

Human beings, afflicted with temporal myopia, habitually view their immediate circumstances as "normal" and look upon any departure from the perceived "norm" as abnormal, something extraordinary to be feared. But in fact, even over the relatively brief course of human history the climate has undergone significant change. A centuries-long period of unusually warm weather called the Medieval Optimum lasted from A.D. 900 to A.D. 1300. During this period agriculture flourished and populations boomed. England rivaled France in wine production. Vikings colonized North America.

Beginning around 1350, however, the Earth was plunged into the Little Ice Age that stretched into the middle of the 19th Century. Crops failed, famine and disease swept Europe. American newspapers, journals and diaries of the 17th and 18th centuries routinely recorded bitterly cold winters (much colder than those of the 20th Century), prodigious blizzards, and northern rivers freezing solid. The Little Ice Age drove the Viking colonies out of Greenland and Newfoundland. The Thames and the Hudson froze solid. Remember Washington's heroic crossing of the ice-choked Delaware in December 1776 to attack the Hessians at Trenton? We're still warming up from this mini-Ice Age and doing just fine, thank you.

The global warming militants persist in talking about "normal" and "abnormal" weather. But there is no such thing as "normal" climate. The Earth's climate is constantly changing, heating up and cooling down. Sea levels rise and fall. Polar caps advance and retreat.

Our planet's atmosphere is an incredibly dynamic and complex engine the intricate workings of which we only dimly understand. Since climatologists cannot agree what caused the sudden onset of the Ice Age cycle, computerized predictions about what the climate will be in future decades are simply guesswork dressed up to appear scientific. A single large volcanic eruption, another Krakatoa for instance, can reverse all the data and institute a period of global cooling, as such events have repeatedly done in our not too distant past.

Super volcanoes, mega-earthquakes, tsunamis, enormous landslides, Ice Ages, sudden changes in climate, ever meteor impacts - all these things are normal, if infrequent, events in our planet's physical history. They only appear unusual because their period of occurrence tends to exceed the typical human lifespan. Hence when they do occur they appear unnatural or extraordinary, like last December's tsunami in the Indian Ocean or this year's hurricanes. Once people blamed such natural events on devils or demons; now we blame Big Oil and the family mini-van. Mr. Lessner is a senior associate at Capital City Partners, a Washington consulting firm.
