This thinking is out of the current mainstream of paleoclimatologists, but George Kukla believes the current period of global warming could be a harbinger of a coming ice age.
(Helium)- Geologic records show that Ice Ages are the norm, punctuated by brief periods of warming. Now one of the most highly respected paleoclimatologists has weighed in and is warning everyone to prepare for a new Ice Age.
A new Ice Age? Then what's all the brouhaha about man-made global warming over the past 20 years?
George Kukla, 77, retired professor of paleoclimatology at Columbia University and researcher at the Lamont-Doherty Earth Observatory responds, "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."
The "Earth has experienced an ongoing cycle of ice ages dating back millions of years. Cold, glacial periods affecting the polar to mid-latitudes persist for about 100,000 years, punctuated by briefer, warmer periods called interglacials," Kukla says.
Co-author of an important section of the book "Natural Climate Variability on Decade to Century Time Scales," Kukla asserts all Ice Ages start with a period of global warming. They are the the harbingers of new Ice Ages. Actually, he explains, warming is good. Ice Ages are deadly and may even kill millions.
