ice age

1. Any of several cold periods during which glaciers covered much of the Earth.
2. Ice Age The most recent glacial period, which occurred during the Pleistocene Epoch and ended about 10,000 years ago. During the Pleistocene Ice Age, great sheets of ice up to two miles thick covered most of Greenland, Canada, and the northern United States as well as northern Europe and Russia.

Ice Age

1. A period during which glaciers advanced to cover large parts of the earth’s surface, the most recent occurring over 11,000 years ago.
2. A time when ice sheets covered much of the Earth. The present Ice Age is only one of several ice ages.

Rather, we have evidence for a very dynamic ice sheet that grew and shrank significantly between glacial and interglacial periods.
There is a direct relationship between hydrological and chemical changes in the Dead Sea over 220,000 years, a time interval covering two glacial and three interglacial periods on Earth, according to research conducted at Ben-Gurion University of the Negev.
Starting about 1,000,000 years ago, the Ice Ages lasted about 100,000 years --separated by a relatively short interglacial periods like the one we are living in at present.
Published this March in the journal Nature, it notes that during past interglacial periods, when the levels of atmospheric C02 were about the same as they are today, 400 ppm, sea levels swelled to nearly 100 feet higher than today's level.
Cold tolerant species often exhibit specific responses to Pleistocene climate oscillations, including range expansions during glacial periods and altitudinal shifts between glacial and interglacial periods.
One approach to this problem is to ask what happened to the ice sheet in the past during interglacial periods such as 130,000 and 205,000 years ago when the world was warmer than at present.
Over the last million years the global climate has varied between glacial periods (with great masses of ice covering the continents in the northern hemisphere) and interglacial periods, with changes approximately every 100,000 years.
The Pleistocene ice age is really a succession of 17 or more glacial periods separated by warmer times, called interglacial periods, when the ice retreats.
During the past 750,000 years, there have been eight ice age cycles separated by warmer, interglacial periods; the Earth now is near the end of an interglacial period that will give way in several thousand years to another ice age.
One of the key observations from palaeoclimate data is that sea-level rises to heights at least several metres above today's level occurred in interglacial periods that were only 1 to 2[degrees]C warmer than today.
So, Huang speculates, oxygen-isotope data from phytoliths--if combined with the results of carbon-dating organic material from the same soil sample--could provide data about Earth's climate during the last three ice ages and interglacial periods.
