George Kukla (Deceased)
- Doctor of Natural Science (RNDr.), Charles University, Prague, (1953). 
According to an interview with Kukla on the program “Truthquest” at KHENLPFM Radio (June 29, 2010), he received his doctorate in 1971 at Charles University as opposed to 1953.
George Kukla was a micropalentologist and Special Research Scientist at the Lamont-Doherty Earth Observatory of Columbia University. He passed away on May 31, 2014. Kukla was an early believer of global cooling and has been described as a “pioneer in the study of solar forcing of climate changes.” , 
Kukla has been quoted in the early 70s in articles discussion the potential for global cooling ,  In the 1980s, Kukla also released research that suggested a global warming trend,  but has since reverted to the view that a future ice age is likely. 
He was the lead author of a paper that first supported Milutin Milankovic's theory of glacial cycles by investigating the stratigraphy in deep-sea sediment cores from the southern Indian Ocean.
In his paper he wrote, “We are certain now that changes in the Earth's orbital geometry caused the ice ages. The evidence is so strong that other explanations must now be discarded or modified.”
Stance on Climate Change
April 24, 2007
“The only thing to worry about global warming is the damage that can be done by worrying. Why are some scientists worried? Perhaps because they feel that to stop worrying may mean to stop being paid.” 
June 24, 2007
“I feel we're on pretty solid ground in interpreting orbit around the sun as the primary driving force behind ice-age glaciation. The relationship is just too clear and consistent to allow reasonable doubt…”
“What I think is this: Man is responsible for a PART of global warming. MOST of it is still natural.”
