 Sallie Baliunas |
Sallie Baliunas is an astrophysicist at the Harvard-Smithsonian Center for Astrophysics in the Solar, Stellar, and Planetary Sciences Division and formerly Deputy Director of the Mount Wilson Observatory. She serves as Senior Scientist at the George C. Marshall Institute in Washington, DC, and chairs the Institute's Science Advisory Board. She is also Visiting Professor at Brigham Young University, Adjunct Professor at Tennessee State University and past contributing editor to the World Climate Report. Previously Robert Wesson Endowment Fund Fellow (1993–1994) at the Hoover Institution. She was a co-host of Tech Central Station.[1]
Degrees and awards
Baliunas received her M.A. (1975) and Ph.D. (1980) degrees in Astrophysics from Harvard University. Her scientific awards include the Newton Lacy Pierce Prize in Astronomy from the American Astronomical Society, awarded in 1988. She also received the Derek Bok Public Service Prize from Harvard University. In 1991 Discover magazine profiled her as one of America's outstanding women scientists.
She has also received a political award, the Petr Beckmann Award for Scientific Freedom from Doctors for Disaster Preparedness, a body associated with the Oregon Institute of Science and Medicine in recognition of her work criticising the theory of global warming.
Astrophysics
Baliunas's main focus is on astrophysical research.[2] 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.
Global warming and solar variability
In 1992, Baliunas was third author on a Nature paper[3] that used observed variations in sun-like stars as an analogue of possible past variations in the Sun. The paper says that
- "the sun is in an unusually steady phase compared to similar stars, which means that reconstructing the past historical brightness record may be more risky than has been generally thought".
Around 2000, she entered the global warming controversy. The work of Willie Soon and Baliunas, suggesting that solar variability is more strongly correlated with variations in air temperature than any other factor, even carbon dioxide levels, has been widely publicized by lobby groups including the Marshall Institute[4] and Tech Central Station,[5] and mentioned in the popular press.[6]
Baliunas is a strong skeptic in regard to there being a connection between CO2 rise and climate change, saying in a 2001 essay with Willie Soon:
- But is it possible that the particular temperature increase observed in the last 100 years is the result of carbon dioxide produced by human activities? The scientific evidence clearly indicates that this is not the case... measurements of atmospheric temperatures made by instruments lofted in satellites and balloons show that no warming has occurred in the atmosphere in the last 50 years. This is just the period in which humanmade carbon dioxide has been pouring into the atmosphere and according to the climate studies, the resultant atmospheric warming should be clearly evident.[7]
The claim that atmospheric data showed no warming trend was incorrect, as the published satellite and balloon data at that time showed a warming trend (see satellite temperature record). In later statements Baliunas acknowledged the measured warming in the satellite and balloon records, though she disputed that the observed warming reflected human influence.[8]
Baliunas contends that findings of human influence on climate change are motivated by financial considerations: "If scientists and researchers were coming out releasing reports that global warming has little to do with man, and most to do with just how the planet works, there wouldn't be as much money to study it."[9] [10]
Controversy over the 2003 Climate Research paper
In 2003, Baliunas and astrophysicist Willie Soon published a review paper on historical climatology in Climate Research, which concluded that "the 20th century is probably not the warmest nor a uniquely extreme climatic period of the last millennium." With Soon, Baliunas investigated the correlation between solar variability and temperatures of the Earth's atmosphere. When there are more sunspots, the total solar output increases, and when there are fewer sunspots, it decreases. Soon and Baliunas attribute the Medieval warm period to such an increase in solar output, and believe that decreases in solar output led to the Little Ice Age, a period of cooling from which the earth has been recovering since 1890.[11]
The circumstances of the paper's publication were controversial, prompting concerns about the publishers' peer review process. An editorial revolt followed and the publisher subsequently stated that critics said that the conclusions of the paper "cannot be concluded convincingly from the evidence provided" and that the journal "should have requested appropriate revisions prior to publication."[12]
Ozone depletion
An article by Baliunas and Soon written for the Heartland Institute in 2000 promoted the idea that ozone depletion rather than CO2 emissions could explain atmospheric warming.[13]
