Is Global Warming Scientifically Understood?

Who And What Is Responsible For Global Warming?
Scientist Says Global Warming A Bunch Of Hooey…

Reid Bryson, known as the father of scientific climatology, considers global warming a bunch of hooey.

The UW-Madison professor emeritus, who stands against the scientific consensus on this issue, is referred to as a global warming skeptic. But he is not skeptical that global warming exists, he is just doubtful that humans are the cause of it.
There is no question the earth has been warming. It is coming out of the “Little Ice Age,” he said in an interview this week.

“However, there is no credible evidence that it is due to mankind and carbon dioxide. We’ve been coming out of a Little Ice Age for 300 years. We have not been making very much carbon dioxide for 300 years. It’s been warming up for a long time,” Bryson said.

The Little Ice Age was driven by volcanic activity. That settled down so it is getting warmer, he said.

Humans are polluting the air and adding carbon dioxide to the atmosphere, but the effect is tiny, Bryson said.

“It’s like there is an elephant charging in and you worry about the fact that there is a fly sitting on its head. It’s just a total misplacement of emphasis,” he said. “It really isn’t science because there’s no really good scientific evidence.”

Just because almost all of the scientific community believes in man-made global warming proves absolutely nothing, Bryson said. “Consensus doesn’t prove anything, in science or anywhere else, except in democracy, maybe.”

The fact that science is many years away from properly understanding global climate doesn’t seem to bother our leaders at all. Inviting testimony only from those who don’t question political orthodoxy on the issue, parliamentarians are charging ahead with the impossible and expensive goal of “stopping global climate change.” Liberal MP Ralph Goodale’s June 11 House of Commons assertion that Parliament should have “a real good discussion about the potential for carbon capture and sequestration in dealing with carbon dioxide, which has tremendous potential for improving the climate, not only here in Canada but around the world,” would be humorous were he, and even the current government, not deadly serious about devoting vast resources to this hopeless crusade.

Climate stability has never been a feature of planet Earth. The only constant about climate is change; it changes continually and, at times, quite rapidly. Many times in the past, temperatures were far higher than today, and occasionally, temperatures were colder. As recently as 6,000 years ago, it was about 3C warmer than now. Ten thousand years ago, while the world was coming out of the thou-sand-year-long “Younger Dryas” cold episode, temperatures rose as much as 6C in a decade — 100 times faster than the past century’s 0.6C warming that has so upset environmentalists.

Solar scientists predict that, by 2020, the sun will be starting into its weakest Schwabe solar cycle of the past two centuries, likely leading to unusually cool conditions on Earth. Beginning to plan for adaptation to such a cool period, one which may continue well beyond one 11-year cycle, as did the Little Ice Age, should be a priority for governments. It is global cooling, not warming, that is the major climate threat to the world, especially Canada. As a country at the northern limit to agriculture in the world, it would take very little cooling to destroy much of our food crops, while a warming would only require that we adopt farming techniques practiced to the south of us.

Those looking for the culprit responsible for global warming have missed the obvious choice - the sun. While it may come as a newsflash to some, scientific evidence conclusively shows that the sun plays a far more important role in causing global warming and global cooling than any other factor, natural or man-made. In fact, what may very well be the ultimate ironic twist in the global warming controversy is that the same solar forces that caused 150 years of warming are on the verge of producing a prolonged period of cooling.

The evidence for future cooling is supported by considerable scientific research that has only recently begun to come to light. It wasn’t until 1980, with the aid of NASA satellites, that scientists definitively proved that the sun’s brightness - or radiance - varies in intensity, and that these variations occur in predictable cyclical patterns. This was a crucial discovery because the climate models used by greenhouse theory proponents always assumed that the sun’s radiance was constant. With that assumption in hand, they could ignore solar influences and focus on other influences, including human.

That turned out to be a reckless assumption. Further investigation revealed that there is a strong correlation between the variations in solar irradiance and fluctuations in the Earth’s temperature. When the sun gets dimmer, the Earth gets cooler; when the sun gets brighter, the Earth gets hotter. So important is the sun in climate change that half of the 1.5° F temperature increase since 1850 is directly attributable to changes in the sun. According to NASA scientists David Lind and Judith Lean, only one-quarter of a degree can be ascribed to other causes, such as greenhouse gases, through which human activities can theoretically exert some influence.

The correlation between major changes in the Earth’s temperature and changes in solar radiance is quite compelling. A perfect example is the Little Ice Age that lasted from 1650 to 1850. Temperatures in this era fell to as much as 2° F below today’s temperature, causing the glaciers to advance, the canals in Venice to freeze and major crop failures. Interestingly, this dramatic cooling happened in a period when the sun’s radiance had fallen to exceptionally low levels. Between 1645 and 1715, the sun was in a stage that scientists refer to as the Maunder Minimum. In this minimum, the sun has few sunspots and low magnetism which automatically indicates a lower radiance level. When the sun began to emerge from the minimum, radiance increased and by 1850 the temperature had warmed up enough for the Little Ice Age to end.

The Maunder Minimum is not an isolated event: it is a cyclical phenomenon that typically appears for 70 years following 200-300 years of warming. With only a few exceptions, whenever there is a solar minimum, the Earth gets colder. For example, Europe in the 13th and 15th Centuries experienced significantly lower temperatures and in both cases the cold spells coincided with a minimum. Similar correlations were found in the 9th Century and again in the 7th Century. Since 8700 B.C., there have been at least ten major cold periods similar to the Little Ice Age. Nine of those ten cold spells coincided with Maunder Minima.

There is no reason to believe that this 10,000-year-old cycle of solar-induced warming and cooling will change. Dr. Sallie Baliunas, an astrophysicist with the Harvard-Smithsonian Center for Astrophysics and one of the nation’s leading experts on global climate change, believes that we may be nearing the end of a solar warming cycle. Since the last minimum ended in 1715, Baliunas says there is a strong possibility that the Earth will start cooling off in the early part of the 21st Century.
