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.

Rain Comes to the Arctic, With a Cascade of Troubling Changes
Rain used to be rare in the Arctic, but as the region warms, so-called rain-on-snow events are becoming more common. The rains accelerate ice loss, trigger flooding, landslides, and avalanches, and create problems for wildlife and the Indigenous people who depend on them.
