The general term "ice age" or, more precisely, "glacial age" denotes a geological period of long-term reduction in the temperature of the Earth's surface and atmosphere, resulting in an expansion of continental ice sheets, polar ice sheets and alpine glaciers. An ice age is a natural system. Within a long-term ice age, individual pulses of extra cold climate are termed "glaciations". Glaciologically, ice age implies the presence of extensive ice sheets in the northern and southern hemispheres;[1] by this definition we are still in an ice age (because the Greenland and Antarctic ice sheets still exist).
More colloquially, "the ice age" refers to the most recent colder period that peaked at the Last Glacial Maximum approximately 20,000 years ago, in which extensive ice sheets lay over large parts of the North American and Eurasian continents. This article will use the term ice age in the former, glaciological, sense: glacials for colder periods during ice ages and interglacials for the warmer periods.
The melting of an enormous Antarctic ice sheet 14,000 years ago triggered climatic changes in Europe and North America that ultimately led to the end of the last ice age, according to a new study.
WND HEAT OF THE MOMENT
Study finds CO2 didn't end ice age
Counters major premise of global warming theory
A new peer-reviewed scientific study counters a major premise of global warming theory, concluding carbon dioxide did not end the last ice age
The study, led by University of Southern California geologist Lowell Stott, concluded deep-sea temperatures rose 1,300 years before the rise in atmospheric CO2, which would rule out the greenhouse gas as the main agent of the meltdown.
"There has been this continual reference to the correspondence between CO2 and climate change as reflected in ice core records as justification for the role of CO2 in climate change," said Stott. "You can no longer argue that CO2 alone caused the end of the ice ages."
Where ever you search.... there are pros and cons on Global Warming.. Whatever the case it's happened before... something ended the Ice Age, or "Glacial Age"...
perhaps a natural cycle of the planet...
Consider the age of earth, then consider the time humans have festered upon its surface...... people are expendable!!!!
GLOBAL WARMING isn't a CROCK.... it's happened before... what's a CROCK, are the folks making a profit because of it.... The earth is resilient, she shall, and often does, eliminates large numbers of the infestation crawling the her surface..
The earth will far outlast the parasites........
