Despite what you may have heard about the death of the coal industry, Peabody Energy is ramping up mining activities and going on the offensive, pushing “clean coal” on the world’s poor with a disingenuous but aggressive PR campaign. And for good reason: Peabody has got to sell the coal from...read more
- 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 is a micropalentologist and Special Research Scientist at the Lamont-Doherty Earth Observatory of Columbia University. 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
“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.” 
“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.”
