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 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 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.
