Willie Wei-Hock Soon (born 1966) is an astrophysicist at the Solar and Stellar Physics Division of the Harvard-Smithsonian Center for Astrophysics. He is known for his views that most global warming is caused by solar variation.
He is chief science adviser to the Science and Public Policy Institute, an organisation which devotes most of its scientific coverage to arguing against anthropogenic global warming or playing down the effects of global warming. In 2003, he was invited to testify in the United States Senate and was later recognized, with an award, for “detailed scholarship on biogeological and climatic change over the past 1000 years” by the Smithsonian Institution. In June 2004, he was presented with the Petr Beckmann award of the by Doctors for Disaster Preparedness for “courage and achievement in defense of scientific truth and freedom.”

Dr Willie Soon is the co-author of a famous article entitled Environmental Effects of Increased Atmospheric Carbon Dioxide.

The 12-page review article rejects the human caused global warming hypothesis. The article and its conclusions is the scientific basis of the Global warming petition project where 31,486 American scientists have signed a petition, to urge the United States government to reject the Kyoto protocol -and any other similar proposal -because there is no convincing scientific evidence that human release of greenhouse gases is causing catastrophic heating of the Earth´s atmosphere.

Sallie Baliunas is an astrophysicist at the Harvard-Smithsonian Center for Astrophysics in the Solar, Stellar, and Planetary Sciences Division.

Baliunas received her M.A. (1975) and Ph.D. (1980) degrees in Astrophysics from Harvard University. In 1991 Discover magazine profiled her as one of America’s outstanding women scientists.

Baliunas’s main focus is on astrophysical research. She studies visible and ultraviolet spectroscopy of stars; structure, variations, and activity in cool stars; evolution of stellar angular momentum; solar variability and global change; adaptive optics; exoplanets of Sun-like stars.

Baliunas is a strong skeptic in regard to there being a connection between CO2 rise and climate change.

David Legates

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”.

Legates has along with his colleagues, Harvard astrophysicists Dr. Willie Soon and Dr. Sallie Baliunas, 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 David Legates and his collegues refuted theese 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).”

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.

Nils-Axel Moerner

Professor Nils-Axel Moerner is a Swedish professor of Paleogeophysics & Geodynamics. He has been leading several field expeditions to the Maldives to study sea level changes:

Nils-Axel Mörner was president for the INQUA commission on Sea Level Changes and CoastalEvolution (1999-2003). His research group spent much effort on the question of present-to-future sea level changes. After intensive field studies, deliberation within the commission and discussions at five international meeting, they agreed on a “best estimate” for possible sea level changes by the year 2100. Their estimate was +10 cm ±10 cm. This estimate was later revised at +5 cm ±15 cm. Such changes would imply small to negligible effects. Mörner states: “From our sea level curve we can directly see that such a small rise would pose no threat for the Maldives. Rather, it would be a natural return to the conditions existing from 1790 to 1970; i.e. to the position before the sea level fall in the 1970s. The same non-rising sea level story is recorded for all other areas claimed to be under a flooding already in progress; viz. Tuvalu, Vanuatu and Venice (Mörner, 2007b).

See Nils-Axel Moerner’s trip to the Maldives.

Prof. Nir Shaviv is a member of the Racah Insitute of Physics at the Hebrew University of Jerusalem.
His research interests cover a wide range of topics in astrophysics. Most are related to the application of fluid dynamics, radiation transfer or high energy physics to a wide range of objects – from stars and compact objects to galaxies and the early universe.
His studies on the possible relationships between cosmic ray intensity and the Earth’s climate, and the Milky Way’s Spiral Arms and Ice Age Epochs on Earth were widely echoed in the scientific literature. They are also described at length in the documentary The Cloud Mystery.

Henrik Svensmark

admin — Mon, 16 Nov 2009 20:05:55 +0000

Professor Henrik Svensmark is the head of the Centre for Sun-Climate Research, at DTU Space, Technical University of Denmark.

Since 1997, Svensmark spearheaded the idea that solar activity variations affect climate on Earth, through solar activity modulating of the cosmic rays reaching the Earth and the effect that these particles have on cloud cover. This idea received a significant boost with the SKY experiment that he headed, which showed under laboratory conditions how the ionization caused by cosmic rays gives rise to the formation of condensation nuclei, a necessary step in the formation of clouds.

This idea is the main theme covered in the documentary The Cloud Mystery (this link includes more information about Svensmarks theory about Cosmoclimatology as well as links to other scientists involved in the research findings. The Cloud Mystery Dvd can be ordered online as well)

You can go to Svensmarks Home page at DTU SPACE.

Here is a brief and simple overview of Cosmoclimatology.
