More than 500 scientists have published evidence refuting the current man-made global warming scare, according to a new analysis of peer-reviewed literature by the Hudson Institute.

The assessment supports another study on which WND reported recently, one that revealed carbon dioxide levels were largely irrelevant to global warming. Those results prompted Reid Bryson, founding chairman of the Department of Meteorology at the University of Wisconsin, to quip, “You can go outside and spit and have the same effect as doubling carbon dioxide.”

The newest analysis was released by Hudson Institute Senior Fellow Dennis Avery, who said of the 500 scientists who have refuted at least one element of the global warming scare, more than 300 have found evidence that a natural moderate 1,500-year climate cycle has produced more than a dozen global warmings similar to the current circumstances since the last Ice Age and that such warmings are linked to variations in the sun’s irradiance.

“This data and the list of scientists make a mockery of recent claims that a scientific consensus blames humans as the primary cause of global temperature increases since 1850,” he said.

“Two thousand years of published human histories say that the warm periods were good for people. It was the harsh, unstable Dark Ages and Little Ice Age that brought bigger storms, untimely frost, widespread famine and plagues of disease,” he said.

Other researchers have found evidence that sea levels are failing to rise importantly, storms and droughts are becoming fewer and milder and human deaths will be reduced with warming because cold kills twice the number of people as heat. Another result was that corals, trees, birds, mammals and butterflies are “adapting well” to the routine reality of changing climate, the analysis said.

The issue of global warming, of course, erupted with the release of the film that former Vice President Al Gore made – and stars in – called “An Inconvenient Truth,” which won an Oscar. It now has become mandatory for students in many high schools and colleges.

Despite the publication of such global warming debunking conclusions in journals including Nature, Geophysical Review Letters and Science, there’s been little media attention, he said.

“Not all of these researchers would describe themselves as global warming skeptics,” noted Avery, “but the evidence in their studies is there for all to see.”

The scientists were compiled by Avery and climate physicist S. Fred Singer, who previously has reported there has been little or no warming since about 1940. The two also co-authored the new book “Unstoppable Global Warming: Every 1,500 Years,” from peer-reviewed studies in specialties including tree rings, sea levels, stalagmites, lichens, pollen, plankton, insects, public health, Chinese history and astrophysics.

“We have had a greenhouse theory with no evidence to support it – except a moderate warning turned into a scare by computer models whose results have never been verified with real-world events,” added Singer. “On the other hand, we have compelling evidence of a real-world climate cycle averaging 1470 years (plus or minus 500) running through the last million years of history. The climate cycle has above all been moderate, and the trees, bears, birds, and humans have quietly adapted.”

Singer said climate model-builders probably have developed a consensus of guesses. “However, the models only reflect the warming, not its cause,” he said.

He said about 70 percent of the Earth’s post-1850 warming came before 1940, and thus was probably not caused by human-emitted greenhouse gases. The net post-1940 warming totals only a tiny 0.2 degrees Celsius, he said.

The analysis said the historic evidence of the temperature fluctuations includes the 5,000-year record of Nile floods, 1st Century Roman wine production in Britain, and thousands of museum paintings that portray sunnier skies during the Medieval Warming and cloudiness during the Little Ice Age.

Physical evidence includes oxygen isotopes, beryllium ions, sea and pollen fossils and ancient tree rings.

For example, Constance Millar of the U.S. Forest Service studied seven species of relict trees that grew above today’s treeline and concluded temperatures during the Medieval Warming Period on Whitewing Mountain in California were about 3.2 degrees warmer than today’s temperatures.

Singer said experiments also have shown more or fewer cosmic rays hitting the Earth create more or fewer low, cooling clouds that deflect solar heat back into space – which amplifies small variations in the intensity of the sun.

The earlier study “Heat Capacity, Time Constant, and Sensitivity of Earth’s Climate System,” was authored by Brookhaven National lab scientist Stephen Schwartz.

“Anthropogenic (man-made) global warming bites the dust,” declared astronomer Ian Wilson after reviewing the study, which was accepted for publication in the peer-reviewed Journal of Geophysical Research.

Bryson’s and Wilson’s comments were among those from a long list of doubters of catastrophic, man-made global warming, assembled by Sen. James Inhofe, R-Okla., and posted on a blog site for the U.S. Senate Committee on Environment and Public Works.

Meteorologist Joseph Conklin, of the website Climate Police said “global warming” is disintegrating.

“A few months ago, a study came out that demonstrated global temperatures have leveled off. But instead of possibly admitting that this whole global warming thing is a farce, a group of British scientists concluded that the real global warming won’t start until 2009,” Conklin wrote.

WND has previously reported on significant doubts about global warming.

Last September, a leading U.S. climate researcher claimed there’s a decade at most left to address global warming before environmental disaster takes place, but the federal government issued a report showing the year 1936 had a hotter summer than 2006.

“The average June-August 2006 temperature for the contiguous United States (based on preliminary data) was 2.4 degrees F (1.3 degrees C) above the 20th century average of 72.1 degrees F (22.3 degrees C),” said the NOAA report. “This was the second warmest summer on record, slightly cooler than the record of 74.7 degrees F set in 1936 during the Dust Bowl era. This summer’s average was 74.5 degrees F. Eight of the past ten summers have been warmer than the U.S. average for the same period.”

WND also reported on NASA-funded study that noted some climate forecasts might be exaggerating estimations of global warming.
