Earth’s orbital changes affect freeze and thaw

Wednesday, August 12th, 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 […]

Current rate of glacial melt may be occurring slower than feared

Friday, July 17th, 2009

However, it appears as though the current rate of glacial melt is occurring at a more gradual pace which will “give ecosystems more […]
