28 Mar 11 - (Excerpts) - Geologic records show that Ice Ages are the norm,
punctuated by brief periods of warming. Now one of the most highly respected
paleoclimatologists - George Kukla, 77, retired professor of
paleoclimatology at Columbia University and researcher at the Lamont-Doherty
Earth Observatory - has weighed in and is warning everyone to prepare for a
new Ice Age.
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," says Kukla.
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.
Can Mankind stop it? No. Just as humanity cannot affect the long term
climate of the planet, neither can it stop an Ice Age from happening. The
climate is primarily driven by the sun.
"I feel we're on pretty solid ground in interpreting orbit around the sun as
the primary driving force behind Ice Age glaciation," he says. "The
relationship is just too clear and consistent to allow reasonable doubt.
It's either that, or climate drives orbit, and that just doesn't make
During a lengthy interview with Gelf Magazine, Kukla explained: "What is
happening is very similar to the time 115,000 years ago, when the last
glaciation started.... Believe it or not, the last glacial started with
He knows that global warming always precedes an Ice Age. The history of that
is in the ice core records repeating itself every 100,000 years or so over
millions of years.
Generations ago, scientists believed Ice Ages advanced slowly taking tens of
thousands of years. Now some researchers have revealed startling evidence
that an Ice Age can be triggered in under 10 years.
Warming is much more preferable than cooling. Warming would actually help
Mankind; cooling will do just the opposite.
Kukla and his colleagues warn that as the ice starts marching southward from
the Arctic there will be "substantially lowered food production" and
evidence will abound of "extreme weather anomalies" in both the northern and
Global superstorms may break out. Some regions may experience anomalous cold
spells while others roast from spiking temperatures never before seen by
Those things too are exactly what's happening now.
Not taken into Kulka's model of an encroaching Ice Age are the facts and
possible impact of the magnetic pole shift, the shifting core of the Earth,
or the revelation by NASA and the ESA that the sun is going to fall into a
quiet period for the next 30 to 50 years.
That exceptional solar minimum cycle is expected to start in 2014, perhaps
It seems the odds are good that the Earth will slip into an extended
cooling, or so-called mini-Ice Age. Whether that becomes an extended 100,000
year full-fledged Ice Age even Kulka doesn't know.
