Earth’s orbital changes affect freeze and thaw

Posted by The College of Science at OSU on August 12, 2009

From the Eugene Register Guard:

Researchers led by a professor at Oregon State University said they finally have confirmed what some scientists have believed for some time: that the last ice age ended because of a slight shift in the Earth’s orbit. The findings could help scientists predict how the planet’s remaining ice will be affected by global warming as well as when the planet will again be topped by miles-thick ice.

OSU geosciences professor Peter Clark is the lead author of a paper published this week in the journal Science. A joint project undertaken by several universities and government agencies, the study pinpointed the timing of the last ice age in an effort to determine which of several planet­wide changes brought the Earth out of the freezer.
