Our transcription: Glaciers and glaciation are among the first subjects that geologists attempted to study, and understanding them is now more important than ever.
Global climate is linked with glaciations, and changes in glaciers are used to make long term predictions of rainfall patterns and of extreme weather such as hurricanes and drought.
Understanding the cause of glacial cycles is also critical to the current debate over global warming and the Greenhouse Effect.
Our interglacial climate is currently undergoing a warming phase, which is at least in part natural.
Some of this warming, however, may be due to the 25 percent increase in atmospheric carbon dioxide that has occurred since 1850.
Only by understanding the natural process of interglacial warming can we accurately monitor and predict any human impact on the climate.
