TIME Magazine Archive Article -- Another Ice Age? -- Jun. 24, 1974(ENVIRONMENTALISM BARF!!!)
TIME MAGAZINE ^ | June 24, 1974/2006 | Time Magazine

In Africa, drought continues for the sixth consecutive year, adding terribly to the toll of famine victims. During 1972 record rains in parts of the U.S., Pakistan and Japan caused some of the worst flooding in centuries. In Canada's wheat belt, a particularly chilly and rainy spring has delayed planting and may well bring a disappointingly small harvest. Rainy Britain, on the other hand, has suffered from uncharacteristic dry spells the past few springs. A series of unusually cold winters has gripped the American Far West, while New England and northern Europe have recently experienced the mildest winters within anyone's recollection.

As they review the bizarre and unpredictable weather pattern of the past several years, a growing number of scientists are beginning to suspect that many seemingly contradictory meteorological fluctuations are actually part of a global climatic upheaval. However widely the weather varies from place to place and time to time, when meteorologists take an average of temperatures around the globe they find that the atmosphere has been growing gradually cooler for the past three decades. The trend shows no indication of reversing. Climatological Cassandras are becoming increasingly apprehensive, for the weather aberrations they are studying may be the harbinger of another ice age.

Telltale signs are everywhere —from the unexpected persistence and thickness of pack ice in the waters around Iceland to the southward migration of a warmth-loving creature like the armadillo from the Midwest.Since the 1940s the mean global temperature has dropped about 2.7° F. Although that figure is at best an estimate, it is supported by other convincing data. When Climatologist George J. Kukla of Columbia University's Lamont-Doherty Geological Observatory and his wife Helena analyzed satellite weather data for the Northern Hemisphere, they found that the area of the ice and snow cover had suddenly increased by 12% in 1971 and the increase has persisted ever since. Areas of Baffin Island in the Canadian Arctic, for example, were once totally free of any snow in summer; now they are covered year round.

Scientists have found other indications of global cooling. For one thing there has been a noticeable expansion of the great belt of dry, high-altitude polar winds —the so-called circumpolar vortex—that sweep from west to east around the top and bottom of the world. Indeed it is the widening of this cap of cold air that is the immediate cause of Africa's drought. By blocking moisture-bearing equatorial winds and preventing them from bringing rainfall to the parched sub-Sahara region, as well as other drought-ridden areas stretching all the way from Central America to the Middle East and India, the polar winds have in effect caused the Sahara and other deserts to reach farther to the south. Paradoxically, the same vortex has created quite different weather quirks in the U.S. and other temperate zones. As the winds swirl around the globe, their southerly portions undulate like the bottom of a skirt. Cold air is pulled down across the Western U.S. and warm air is swept up to the Northeast. The collision of air masses of widely differing temperatures and humidity can create violent storms—the Midwest's recent rash of disastrous tornadoes, for example.

Sunspot Cycle. The changing weather is apparently connected with differences in the amount of energy that the earth's surface receives from the sun. Changes in the earth's tilt and distance from the sun could, for instance, significantly increase or decrease the amount of solar radiation falling on either hemisphere—thereby altering the earth's climate. Some observers have tried to connect the eleven-year sunspot cycle with climate patterns, but have so far been unable to provide a satisfactory explanation of how the cycle might be involved.

Man, too, may be somewhat responsible for the cooling trend. The University of Wisconsin's Reid A. Bryson and other climatologists suggest that dust and other particles released into the atmosphere as a result of farming and fuel burning may be blocking more and more sunlight from reaching and heating the surface of the earth.

Climatic Balance. Some scientists like Donald Oilman, chief of the National Weather Service's long-range-prediction group, think that the cooling trend may be only temporary. But all agree that vastly more information is needed about the major influences on the earth's climate. Indeed, it is to gain such knowledge that 38 ships and 13 aircraft, carrying scientists from almost 70 nations, are now assembling in the Atlantic and elsewhere for a massive 100-day study of the effects of the tropical seas and atmosphere on worldwide weather. The study itself is only part of an international scientific effort known acronymically as GARP (for Global Atmospheric Research Program).

Whatever the cause of the cooling trend, its effects could be extremely serious, if not catastrophic. Scientists figure that only a 1% decrease in the amount of sunlight hitting the earth's surface could tip the climatic balance, and cool the planet enough to send it sliding down the road to another ice age within only a few hundred years.

The earth's current climate is something of an anomaly; in the past 700,000 years, there have been at least seven major episodes of glaciers spreading over much of the planet. Temperatures have been as high as they are now only about 5% of the time. But there is a peril more immediate than the prospect of another ice age. Even if temperature and rainfall patterns change only slightly in the near future in one or more of the three major grain-exporting countries—the U.S., Canada and Australia —global food stores would be sharply reduced. University of Toronto Climatologist Kenneth Hare, a former president of the Royal Meteorological Society, believes that the continuing drought and the recent failure of the Russian harvest gave the world a grim premonition of what might happen. Warns Hare: "I don't believe that the world's present population is sustainable if there are more than three years like 1972 in a row."

Be worried, be very worried

The climate is crashing, and global warming is to blame

Sunday, March 26, 2006; Posted: 11:27 a.m. EST (16:27 GMT)

Editor's note: The following is a summary of this week's Time magazine cover story.

And with sea ice vanishing, polar bears are starting to turn up drowned.

(Time.comexternal link) -- No one can say exactly what it looks like when a planet takes ill, but it probably looks a lot like Earth

Never mind what you've heard about global warming as a slow-motion emergency that would take decades to play out. Suddenly and unexpectedly, the crisis is upon us.

From heat waves to storms to floods to fires to massive glacial melts, the global climate seems to be crashing around us.

The problem -- as scientists suspected but few others appreciated -- is that global climate systems are booby-trapped with tipping points and feedback loops, thresholds past which the slow creep of environmental decay gives way to sudden and self-perpetuating collapse. That's just what's happening now.

It's at the north and south poles -- where ice cover is crumbling to slush -- that the crisis is being felt the most acutely.

Late last year, for example, researchers analyzed data from Canadian and European satellites and found that the Greenland ice sheet is not only melting, but doing so faster and faster, with 53 cubic miles draining away into the sea last year alone, compared to 23 cubic miles in 1996.

One of the reasons the loss of the planet's ice cover is accelerating is that as the poles' bright white surface disappears it changes the relationship of the Earth and the sun. Polar ice is so reflective that 90 percent of the sunlight that strikes it simply bounces back into space, taking its energy with it. Ocean water does just the opposite, absorbing 90 percent of the light and heat it receives, meaning that each mile of ice that melts vanishes faster than the mile that preceded it.

This is what scientists call a feedback loop, and a similar one is also melting the frozen land called permafrost, much of which has been frozen -- since the end of last ice age in fact, or at least 8,000 years ago.

Sealed inside that cryonic time capsule are layers of decaying organic matter, thick with carbon, which itself can transform into CO2. In places like the southern boundary of Alaska the soil is now melting and softening.

As fast as global warming is changing the oceans and ice caps, it's having an even more immediate effect on land. Droughts are increasingly common as higher temperatures also bake moisture out of soil faster, causing dry regions that live at the margins to tip into full-blown crisis.

Wildfires in such sensitive regions as Indonesia, the western U.S. and even inland Alaska have been occurring with increased frequency as timberlands grow more parched. Those forests that don't succumb to fire can simply die from thirst.

With habitats crashing, the animals that call them home are succumbing too. In Alaska, salmon populations are faltering as melting permafrost pours mud into rivers, burying the gravel the fish need for spawning. Small animals such as bushy tailed rats, chipmunks and pinion mice are being chased upslope by rising temperatures, until they at last have no place to run.

And with sea ice vanishing, polar bears are starting to turn up drowned. "There will be no polar ice by 2060," says Larry Schweiger, president of the National Wildlife Federation. "Somewhere along that path, the polar bear drops out."

So much environmental collapse has at last awakened much of the world, particularly the 141 nations that have ratified the Kyoto treaty to reduce emissions. The Bush administration, however, has shown no willingness to address the warming crisis in a serious way and Congress has not been much more encouraging.

Sens. John McCain and Joe Lieberman have twice been unable to get even mild measures to limit carbon emissions through a recalcitrant Senate.

A 10-member House delegation did recently travel to Antarctica, Australia and New Zealand to meet with scientists studying climate change. "Of the 10 of us, only three were believers to begin with," says Rep. Sherman Boehlert of New York. "Every one of the others said this opened their eyes."

But lawmakers who still applaud themselves for recognizing global warming are hardly the same as lawmakers with the courage to reverse it, and increasingly, state and local governments are stepping forward.

The mayors of more than 200 cities have signed the U.S. Mayors Climate Protection Agreement, pledging, among other things, that they will meet the Kyoto goal of reducing greenhouse emissions in their own cities to 1990 levels by 2012. Nine northeastern states have established the Regional Greenhouse Gas Initiative for the purpose of developing a program to cap greenhouse gasses.

You have been pinged because of your interest in environmentalism, alarmist wackos, mainstream media doomsday hype, and other issues pertaining to global warming. Freep-mail me to get on or off. Please ping me to all note-worthy threads on global warming.

We all know about the Newsweek article, but I didn't recall this one, which is essentially the same.

I have a copy of "Forecasts, Famines and Freezes" by John Gribben published November 1977. On the back cover it says

Item: A 2 degree winter temperature drop could raise the U.S. fuel bill by at least $10,000,000,000.

Item: A diversion of monsoon rains in Central India means no grain harvest for 37,000,000 people

Item: We have just lived through the worst winter in a century. Dr. John Gribben predicts that savage winters will continue for the next 30 years.

With the world entering a mini ice-age, it is vital that scientists recognize the enormity of the crisis in terms of world economics, food and energy supply, and political implications. In this highly important book, Dr. Gribben examines the capabilities and limitations of conventional forecasting techniques and the role they will play in the single most important area of scientific research in modern times.

No, no, get with the program...

Global warming is going to cause the next ice age...

They've got their bases covered...

No matter what happens they're right...

Like that scientifically accurate movie *The Day After Tomorrow* ROTFLOL!!!!!!!!

hee hee...hee... so fuel emissions(caused by the election of Nixon,) were first causing dust particles to block the heat of the sun from reaching the earth. Nixon did this to wreak havok to those on his "enemey list" Then when..."Bush stole the election" in 2000, he told all his oil buddy friends to refine oil to make the gas emissions that will heat up the earth and melt the ballots in Florida to hide the evidence.

The question to ask here is:

If temps dropped globally by and average of 2.7 degrees, then could it not be argued that the RISE in average temps since 1974 brings us BACK to pre-1940 levels?

It would be great to find a quote warning of global cooling from a young House member from Tennessee in the 70's, namely Al Gore.
