The Planet is Sick

In his “award winning” film, An Inconvenient Truth, Al Gore declares that “the planet is sick.” Most of us would agree that there are numerous things wrong—and global warming may not be the biggest problem—but the ailments may not warrant the death sentence the environmental extremist’s prescribe. If you were given a dire prognosis by your doctor, would you shrug, accept his (or her) opinion, and go home to die? No! You’d go and get a second opinion—maybe a third. You’d do research on the disease. You’d learn all you could before you gave in and made extreme changes in your life in the hope that the unproven methods may improve your chances for survival. Why then, when the “doctor” (whose credentials are questionable) has pronounced a virtual death sentence on the planet, has the American population suddenly accepted the diagnosis without getting additional opinions, without doing research?

At CARE we are not claiming to be the expert on the topic of global warming, but we do believe there is other opinion worthy of consideration. We do think the public needs to know some of the other research. Here (in many different postings) we present the “other side,” not specifically because we are crusading for this view point, but because the “planet is sick” side is adequately covered through the mainstream media. The “responsible” view is scoffed at, and skeptics have received death threats for presenting their opposing ideas in a public forum. For those who seek a second or third opinion, we have gathered some data that we think will help in your search for answers and will help you form your own responsible opinion. Do these insights help you? Please add your comments.

The New Math On Global Warming
The UN climate change panel told us in 2001 that human-emitted CO2 might drive the planet’s average temperature upward by 5.8 degrees C—a bigger average warming than the world has had in the past 100,000 years. The UN’s 2007 report scales the possible overheating back a bit, to a maximum of 4.5 degrees—still a very large warming.

But wait! The environmental movement is now conceding that the earth has a natural, moderate climate cycle. Jon Coifman of the Natural Resources Defense Council said recently on the Hannity and Colmes TV show, “The earth has natural temperature and climate cycles. Nobody has disputed that.”

We’re glad that the NRDC finally accepts the natural warming cycle as fact. Until Coifman’s admission, I don’t think the words “natural climate cycle” had ever escaped the lips of a climate alarmist.

The historic evidence of a moderate, natural 1,500-year climate cycle includes Roman writings, Egypt’s early Nile flood records, and ancient Chinese court documents. The scientific evidence confirming the cycle has been literally “dug up” in the past 25 years, primarily from the oxygen isotopes in long, layered ice cores, and the one-celled fossils in the bottom sediments of lakes and oceans.

My favorite temperature proxy is North America’s fossil pollen, which shows our continent has had nine complete shifts in its trees and plants over the past 14,000 years—or one every 1650 years. In my native Michigan, the pollen says the forests during the warmings have been dominated by warmth-loving beech trees, with more oak trees intruding as the climate cools, followed by more pine trees. Today, 150 years into a warming, the pine trees are giving way again to the oaks, and the beech trees are waiting their turn.

Coifman is still talking about the planet passing a “crisis tipping point.” He doesn’t seem to realize that the existence of this natural cycle profoundly changes the math on global warming. The eco-movement and Al Gore have been repeating the mantra that “the earth has warmed 0.6 degree C in the last century.” They claim this has been due to more human-emitted CO2, and project Big Warming on that basis. When we plug in the 1,500-year cycle, however, we have to take away from the scary computer models the 0.5 degrees of warming that occurred before 1940—and thus before much human-emitted CO2.

The earth has warmed only a net 0.2 degrees C of net warming since 1940. Human-emitted CO2 gets the blame for only half of that—or 0.1 degree C of warming over 65 years! We’ve had no warming at all since 1998.

Remember, too, that each added unit of CO2 has less impact on the climate. The first 40 parts per million of human-emitted CO2 added to the atmosphere in the 1940s had as much climate impact as the next 360 ppm.

Why does NRDC say that the earth has reached a “crisis tipping point” when we’ve had only 0.2 degrees C of warming over the last 65 years—and no warming at all over the past eight years? How do the Greens project a mind-numbing surge of global warming from this New Math on Global Warming?

Is the emerging evidence of the natural cycle the real crisis for Al Gore and the warming alarmists?

An interesting item about Gore, who is supposed to be in town sometime soon. He claims that he cannot speak to reporters because his contract forbids it. That’s preposterous. All authors and filmmakers do as many interviews as they can as a sales tool. I’ve NEVER heard of anyone being restricted by contract. For what reason? And why did Gore agree to an interview with a magazine reporter and Bjorn Lomborg earlier this year only to cancel at the last minute? Where was his contract then?

Gore does not do interviews because there are so many holes in what he is claiming.
