(CNSNews.com) – After reviewing thousands of peer-reviewed scientific papers, an international team of 47 scientists has concluded that carbon dioxide (CO2) emissions caused by human activity had little measurable impact on the Earth’s climate during the 20th century, and that computer models predicting ever-rising temperatures as a result of greenhouse gas emissions are seriously flawed.
“None of them have been validated against actual observations. They have not been able to explain why the climate hasn’t warmed in at least 15 years even though that’s what every model expects,” Dr. S. Fred Singer said during a conference call Tuesday. “Antarctic ice is growing steadily despite the models predicting the opposite.”
Professor emeritus of environmental science at the University of Virginia, Singer criticized the U.N.’s Intergovernmental Panel on Climate Change (IPCC), whose latest report is scheduled to be released on Sept. 27 in Stockholm. Using CO2 “to account for all temperature variations leaves no room for the sun, and is contradicted by every other temperature record,” Singer said.
Singer is the lead author of “Climate Change Reconsidered,” which was released Tuesday. It is the third volume in a series published by the Non-Governmental International Panel on Climate Change (NIPCC). The “double peer-reviewed study” was sponsored by the Science and Environmental Policy Project (SEPP), Center for the Study of Carbon Dioxide and Global Change, and the Heartland Institute.
“Some models predict more cloud cover, some less, some no change,” agreed Dr. Willie Soon, a solar expert and co-author of the NIPCC study. “So anything goes. That is not the way science works,” added Soon, chief science advisor at the Science and Public Policy Institute.
Co-author Dr. Craig Idso, chairman of the Center for the Study of Carbon Dioxide and Global Change, said that “claims that temperatures in the polar regions are rising is patently false,” adding that “empirical data for the past 1,000 years” shows no evidence that CO2 levels cause droughts, floods, hurricanes or other severe weather. Nor did storms in the 20th century increase in either intensity or frequency over previous centuries, Idso said.
“This new volume provides the scientific balance missing from IPCC,” Idso said. Global temperatures have risen slightly because the Earth is still coming out of the Little Ice Age (800-1100 A.D.), the coldest temperatures recorded in the last 10,000 years, he noted. “But thousands of peer-reviewed scientific articles do not support, and often contradict the IPCC’s view on climate change.”
Contrary to the UN panel, the NIPCC study concludes that “the human effect (from CO2 emissions) is likely to be small relative to natural variability, and whatever small warming is likely to occur will produce benefits as well as costs.”
