Earth science: Baked Alaska
Peter Clift & Karen Bice
Abstract
The warming of the Earth's climate more than 50 million years ago is as yet unexplained. Now the finger points to the heating of sediment in the Gulf of Alaska as an important source of the greenhouse gas methane.
Between about 58 and 52 million years ago, during the late Palaeocene and early Eocene epochs, the Earth's climate warmed considerably. What was the cause of this unusually long warming trend?
- Peter Clift and Karen Bice are in the Department of Geology and Geophysics, Woods Hole Oceanographic Institution, Woods Hole, Massachusetts 02543, USA.
