Al Gore is a politician, not a scientist. He politicizes what appears to be a majority view in science not having the slightest ability to determine the reliability of the information is which he is given.

Persons who don’t have a background in science tend to assume that the first thing they encounter in science must be unquestionable fact. They don’t understand how treacherous science is.

Science explores the boundaries of knowledge in abstract areas. At the operating front of science, knowledge is extremely illusive.

The supposed majority view of humans causing global warming, which he describes as total, is nothing of the sort. Opposing scientists have been intimidated into silence. In 1998, before there was much publicity on global warming, 17,000 scientists signed a petition saying humans are not the cause of global warming. (External Link) Since then, scientists have been intimidated into silence. But a few are coming back into the open and speaking out.

Recently, Marc Morano, staffer for the Senate Environment and Public Works Committee, published a list of 400 scientists who are speaking out against the propaganda claim that humans are the cause of global warming. (Source Page at Senate EPW)

Al Gore referred to the Naomi Oreske’s study of 2004 which reviewed 928 published articles in science and found that 75% promoted the human cause of global warming, 25% were indifferent and none claimed humans were not the cause. To Al Gore, none means none. That’s the difference between propaganda and science. None does not mean none in science. The quality of the study determines the validity of the conclusion. What the none really means is that bureaucrats refuse to fund scientists who do not promote their agenda of proving that humans are the cause of global warming. (See How Firing Works.)

The first item mentioned in Al Gore’s movie is sun rays striking the earth and humans preventing the rays from reflecting back into space due to a “thickening of the atmosphere.” That isn’t what happens. There are no sun ray frequencies which would go into space without human activity. In fact, there is no scientifically valid mechanism for carbon dioxide creating global warming, as I explain in much detail elsewhere.

Greenhouse gasses absorb all radiation available to them in a few meters of distance. More greenhouse gas only shortens the distance. For analogy, a thick sheet of plastic does nothing more than a thin sheet of plastic.

There are two other major points of science which he mentions. One is whether oceans will rise 20 feet, and the other is whether ice core measurements prove that humans are the cause.

Nothing is easier to spin than predictions of weather including how ice might melt. So the movie produced more spin than fact on ice melting. One point was the melting of an Antarctica ice sheet. Ice over oceans has been melting rapidly—in fact, much more rapidly than Al Gore said it would. But this shows that it is not humans which are the cause. Warm ocean currents are the cause, and neither humans nor greenhouse gasses have the ability to add that much heat to ocean currents that rapidly.

Over the past few years, warm ocean currents have shifted, so ice is now accumulating around Antarctica and disappearing rapidly around the Arctic.

During the sixties, a concern was that oceans were rising, not due to greenhouse gasses but the natural warm-up between ice ages, and if ocean currents were to go over the Bering Strait, they would melt the Artic ice and trigger another ice age—not due to greenhouse gasses but due to the natural cycle between ice ages. That’s exactly what is happening now.

The movie focuses on ice melting and forming pools of water on both Antarctica and Greenland. The water then lubricates the flow of ice into the oceans. Actual measurements show that this effect is minimal at this time—ocurring near the shore—and is being counter-balanced by accumulating ice farther inland. (See Oceans not Rising.)

This is not to say what might happen in the future. Wild things happen during ice age cycles. This is saying that, one: existing evidence shows only seven inches of ocean rise per century, and, two: whatever happens down the road, it won’t be caused by humans putting carbon dioxide into the air, though it could be cause by dumping iron into the oceans and turning them into a cesspool, or flooding space with reflective materials which can‘t be removed, etc.

Al describes ice core measurements as if they were a fine tuned instrument. In truth they are witchcraft to a point of fraud. (See Ice Core Measurements.) Ice core measurements supposedly show a major jump in atmospheric CO2 correlating with human activity. But more reliable evidence, which includes actual measurements in the atmosphere going back more than a century, show just as much CO2 in the atmosphere, with many variations, going back before human industrialization. See 30% Fraud

Al Gore’s movie put a political spin on a version of science which is too imaginative. That version of science relies upon weak and misleading evidence which needed to be evaluated against more reliable evidence, which is gradually occurring over time showing point after point that the human cause of global warming is an incorrect assumption. (See Recent Letter by Scientists to IPCC.)

The over-all problem with Al Gore’s approach is that he does not consider evidence of the causes for the effects which he mentions. He assumes there could be no other cause than humans putting carbon dioxide in the air. Assuming without evidence is a misrepresentation. It’s the difference between propaganda and science.

He mentions insects migrating, diseases developing and glaciers melting, as if they could not be caused by anything other than increased carbon dioxide in the air. Those forces are always changing. Insects are always migrating; diseases are always flaring up someplace and glaciers are always increasing and receding. Other critics and recent science have shown that there are other explanations for each of his points.
