Sediment Dampens the Impact of Glaciation on Cenozoic Denudation
Rates of continental-scale sediment flux and denudation are similar between glacial and interglacial periods when the aggradation of glacier-eroded sediment inhibits fluvial erosion downstream.

A Better Way to Predict Arctic Riverbank Erosion
Permafrost thaw might cause Arctic riverbanks to erode more quickly. But a new study shows why these erosion rates aren’t as dramatic as some scientists feared.
