Dr. George Kukla

The Interview:

Dr. George Kukla is a retired professor of geology at Columbia University and a researcher at the Lamont-Doherty Earth Observatory.  He was a member of the Czechoslovakian Academy of Sciences prior to emigrating the U.S., how and when will it end?”  Kukla and Matthews then highlighted the dangers of global cooling in Science magazine and to President Richard Nixon.


The Nixon administration reacted swiftly to their letter, which described calamities such as killer frosts, lower food production and floods, to come.  By February, 1973, the State Department had established a panel on the Present Interglacial, which advised Drs. Kukla and Matthews that it “was seized of the matter” and numerous other government agencies were soon included.   


Kukla was co-author of a chapter in the book “Natural Climate Variability on Decade to Century Time Scales” published by the National Research Council.  He believes all glacial periods in Earth’s history began with global warming (understood as an increase of area-weighted average global mean temperature).  He believes Earth’s recent warming is mostly natural and will ultimately lead to a new ice age.
