Arctic river erosion linked to permafrost thaw

Permafrost, the thick layer of perennially frozen ground that covers much of the Arctic, slows down the migration of Arctic rivers, according to a new Caltech study. River migration is a common process in which a river's ...

Professor helps discover global gap in geologic record

About 34 million years ago, Earth began to cool dramatically, transforming the climate from greenhouse to icehouse and causing sea levels to fall. As more land was exposed to weathering forces, copious amounts of sediment ...
