Very interesting super long CHART showing temperature across last five hundred of millions of years. Also shows that we are right now in a interglacial (relatively slight warming period)in a REALLY long-term ice age. The "man-made global warming" looks pretty tasty to me right now!

http://en.wikipedia.org/wiki/Timeline_of_glaciation

"There have been five or six major ice ages in the history of Earth over the past 3 billion years. The Late Cenozoic Ice Age began 34 million years ago, its latest phase being the Quaternary glaciation, in progress since 2.58 million years ago.

Within ice ages, there exist periods of more severe glacial conditions and more temperate conditions, referred to as glacial periods and interglacial periods, respectively. The Earth is currently in such an interglacial period of the Quaternary glaciation, with the last glacial period of the Quaternary having ended approximately 11,700 years ago. The current interglacial is known as the Holocene epoch.[1] Based on climate proxies, paleoclimatologists study the different climate states originating from glaciation.

Why did the last ice age end?

Nearly 10,000 years ago, Earth came out of its most recent ice age. Vast, icy swaths of land around the poles thawed, melting the glaciers that had covered them for nearly 100,000 years.
>>>


In a nutshell, 'They' do not know why the last ice age ended.

But, they do have an interesting graphic - which claims that the earth's orbit changes in eccentricity in a 100,000 year cycle.

Now it seems to me that if the earth is further away from the sun for a while, the earth will receive less solar energy and we will get 'global cooling' - i.e. an ice age.

When the earth moves closer to the sun, more solar energy hits the earth, and we have a warming period.

But what do I know?

Zim.
