Plus Ça (Climate) Change
The Earth was warming before global warming was cool.

BY PETE DU PONT

When Eric the Red led the Norwegian Vikings to Greenland in the late 900s, it was an ice-free farm country--grass for sheep and cattle, open water for fishing, a livable climate--so good a colony that by 1100 there were 3,000 people living there. Then came the Ice Age. By 1400, average temperatures had declined by 2.7 degrees Fahrenheit, the glaciers had crushed southward across the farmlands and harbors, and the Vikings did not survive.

Such global temperature fluctuations are not surprising, for looking back in history we see a regular pattern of warming and cooling. From 200 B.C. to A.D. 600 saw the Roman Warming period; from 600 to 900, the cold period of the Dark Ages; from 900 to 1300 was the Medieval warming period; and 1300 to 1850, the Little Ice Age.

During the 20th century the earth did indeed warm--by 1 degree Fahrenheit. But a look at the data shows that within the century temperatures varied with time: from 1900 to 1910 the world cooled; from 1910 to 1940 it warmed; from 1940 to the late 1970s it cooled again, and since then it has been warming. Today our climate is 1/20th of a degree Fahrenheit warmer than it was in 2001.

Many things are contributing to such global temperature changes. Solar radiation is one. Sunspot activity has reached a thousand-year high, according to European astronomy institutions. Solar radiation is reducing Mars's southern icecap, which has been shrinking for three summers despite the absence of SUVS and coal-fired electrical plants anywhere on the Red Planet. Back on Earth, a NASA study reports that solar radiation has increased in each of the past two decades, and environmental scholar Bjorn Lomborg, citing a 1997 atmosphere-ocean general circulation model, observes that "the increase in direct solar irradiation over the past 30 years is responsible for about 40 percent of the observed global warming."
Statistics suggest that while there has indeed been a slight warming in the past century, much of it was neither human-induced nor geographically uniform. Half of the past century's warming occurred before 1940, when the human population and its industrial base were far smaller than now. And while global temperatures are now slightly up, in some areas they are dramatically down. According to "Climate Change and Its Impacts," a study published last spring by the National Center for Policy Analysis, the ice mass in Greenland has grown, and "average summer temperatures at the summit of the Greenland ice sheet have decreased 4 degrees Fahrenheit per decade since the late 1980s." British environmental analyst Lord Christopher Monckton says that from 1993 through 2003 the Greenland ice sheet "grew an average extra thickness of 2 inches a year," and that in the past 30 years the mass of the Antarctic ice sheet has grown as well.

Earlier this month the U.N.'s Intergovernmental Panel on Climate Change released a summary of its fourth five-year report. Although the full report won't be out until May, the summary has reinvigorated the global warming discussion.
While global warming alarmism has become a daily American press feature, the IPCC, in its new report, is backtracking on its warming predictions. While Al Gore's "An Inconvenient Truth" warns of up to 20 feet of sea-level increase, the IPCC has halved its estimate of the rise in sea level by the end of this century, to 17 inches from 36. It has reduced its estimate of the impact of global greenhouse-gas emissions on global climate by more than one-third, because, it says, pollutant particles reflect sunlight back into space and this has a cooling effect.

The IPCC confirms its 2001 conclusion that global warming will have little effect on the number of typhoons or hurricanes the world will experience, but it does not note that there has been a steady decrease in the number of global hurricane days since 1970--from 600 to 400 days, according to Georgia Tech atmospheric scientist Peter Webster.

The IPCC does not explain why from 1940 to 1975, while carbon dioxide emissions were rising, global temperatures were falling, nor does it admit that its 2001 "hockey stick" graph showing a dramatic temperature increase beginning in 1970s had omitted the Little Ice Age and Medieval Warming temperature changes, apparently in order to make the new global warming increases appear more dramatic.

Sometimes the consequences of bad science can be serious. In a 2000 issue of Nature Medicine magazine, four international scientists observed that "in less than two decades, spraying of houses with DDT reduced Sri Lanka's malaria burden from 2.8 million cases and 7,000 deaths [in 1948] to 17 cases and no deaths" in 1963. Then came Rachel Carson's book "Silent Spring," invigorating environmentalism and leading to outright bans of DDT in some countries. When Sri Lanka ended the use of DDT in 1968, instead of 17 malaria cases it had 480,000.
Yet the Sierra Club in 1971 demanded "a ban, not just a curb," on the use of DDT "even in the tropical countries where DDT has kept malaria under control." International environmental controls were more important than the lives of human beings. For more than three decades this view prevailed, until the restrictions were finally lifted last September.

As we have seen since the beginning of time, and from the Vikings' experience in Greenland, our world experiences cyclical climate changes. America needs to understand clearly what is happening and why before we sign onto U.N. environmental agreements, shut down our industries and power plants, and limit our economic growth.

Try doing a search for Al Gore and his global warming campaign?

I sent this letter to Al Gore-no responce yet: I would like to propose the biggest cleanup in history, cleaning up the atmosphere. I do not see any proposal, realistic or proven, at any cost, that can solve the problem of global warming. Not even Washington can throw enough money to solve climate change. I see governments acting like a deer in a car’s headlights and unfortunately, many people acting the same. Meanwhile, the inevitable disaster is almost upon us, if not here already. Beyond cleaning up our atmospheric mess as I am suggesting, we humans must do a better job reducing or cleaning up carbon monoxide, burning less of everything, collecting and storing methane and ethane to be used as fuel, cleaning up our forests, using more solar insolation and recycling everything. But even if every person on earth does his or her share, we may not be ok.
Making a plan that includes cleanup of the atmosphere and decisive change is the only option. The technology to start cleaning up and reintroducing new ozone to the atmosphere with little pollution is possible. The ten year cost of one hundred billion dollars, and the scope of this project takes a long term commitment. The first cleanup machine starts with a ten billion dollars investment. Ten year later with twenty-five machines operating, these machines will produce enough ozone to replace both holes at the poles. But more importantly, these machines will remove chemicals that deplete the ozone. Beyond making ozone, decreasing the poisons that deplete ozone, these machines reduce the major greenhouse gases, and that is just the start.
Using solar steam electric generators to produce electricity at near 90 percent efficiency will help reduce global warming. I can see over the next 30 years the world needing 60,000 MW costing one hundred billion dollars. This opens the door to new electric cars and busses and new bullet trains with dramatic reduction in greenhouse gases from cars and planes. With a plan, all governments can help: tax pollution, donate some land and money, and reduce solar steam electric generators regulation to help save the planet from disaster. From getting grants to patents and from land to changing regulations the plan is the start of changing our world.
Carter, the message that we can help ourselves is a key to changing the global warming debate. We start helping ourselves by making the plan, getting everyone to agree and getting everyone to pay the real price. Creating a pollution surcharge on gas, coal, diesel, wood, cooling towers, cattle, other ranches, cigarettes, agriculture burning, airplane passengers; this surcharge can fund of these projects and many stationary pollution control devices in general.

A better Q is what can I do about making life better for humans.
