Warming Not Unusual

admin — Wed, 20 Jan 2010 11:26:56 +0000

The 20th century warming is not unusual, Says Dr. Sallie Baliunas and Dr. Willie Soon from the harvard.

They have conducted a resarch that once and for all confirms that the climate globally have had swings up and down for the last 10.000 years. Of special interest is the claim that the MWP from year 900 to 1300 was warmer than today….

Sallie Baliunas has along with her colleagues, Harvard astrophysicists Dr. Willie Soon and Dr. David Legates, in strong terms criticised the validity of the “hockey stick” by Michael Mann. The hockey stick were for many years the icon of manmade global warming. The pilar that the arguments were standing on. Michael Mann argued that the warming in the last 100 years were unpresidented and it was 98% likely that humans were to blame. His temperature grapfh completely deleted the Medieval Warm period and the Little Ice Age. But Baliunas and Soon and his colleagues refuted these claims in a now famous article from 2003:

RECONSTRUCTING CLIMATIC AND ENVIRONMENTAL CHANGES OF THE PAST 1000 YEARS: A REAPPRAISAL

Part of the conclusion goes like this:

“After examining more than 240 individual proxy records analyzed by nearly 1000 researchers, we concluded that taken individually, proxy records offer strong support for the widespread existence of both a Medieval Warm Period (~A.D. 800 to 1300) and a Little Ice Age (~A.D. 1400 to 1850), undermining Mann’s conclusion that the climate of the 20th Century was unusual when compared to the variability over the last millennium. (Proxy records are secondary or inferred sources from which assumptions about air temperature may be drawn).” Find the full .pdf article here.

The Greenhouse and CO2

The greenhouse and CO2 is not straight on a simple matter. “It´s more complicated than the IPCC proclaims” argues Dr. Sallie Baliunas.

David R. Legates is an Associate Professor and Director of the Center for Climatic Research at the University of Delaware and a Research Fellow at The Independent Institute in Oakland, California.

Legates is a signer of the Oregon Petition, which stated:

“There is no convincing scientific evidence that human release of carbon dioxide, methane, or other greenhouse gasses is causing or will, in the foreseeable future, cause catastrophic heating of the Earth’s atmosphere and disruption of the Earth’s climate. Moreover, there is substantial scientific evidence that increases in atmospheric carbon dioxide produce many beneficial effects upon the natural plant and animal environments of the Earth”.

Part of the conclusion goes like this:

Since Legates, Baliunas and Soon criticized Michael Mann also Steve McIntyre a canadian mathematician has pointed to the scientific flaws in Michael Mann´s graph. Now The Mann Made Hockey-stick is deleted from the IPCC 2007 report.

John R Christy

John Christy, Professor of Atmospheric Science and Director of the Earth. System Science Center at the University of Alabama in Huntsville.

In 1989 Christy and Dr. Roy W. Spencer, a NASA/Marshall scientist, developed a global temperature data set from microwave data observed from satellites beginning in 1979. For this achievement, the Spencer-Christy team was awarded NASA’s Medal for Exceptional Scientific Achievement in 1991. In 1996, they were selected to receive a Special Award by the American Meteorological Society “for developing a global, precise record of earth’s temperature from operational polar-orbiting satellites, fundamentally advancing our ability to monitor climate.
John Christyhas published many articles including studies appearing in Science, Nature, Journal of Climate and The Journal of Geophysical Research. Dr. Christy has provided testimony to several congressional committees.

Christy is a strong critic of scientists who make catastrophic predictions of huge increases in global temperatures and tremendous rises in sea levels.
