A Better Way to Predict Arctic Riverbank Erosion

Rachel Fritts, Science Writer by Rachel Fritts 24 April 202424 April 2024

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.

Another Record-Breaking Year in the Arctic Amplifies Calls for More Data

by Grace van Deelen 12 December 202313 December 2023

A downward spiral of the Arctic’s ecological health and climatic conditions continued in 2023, causing problems for people, plants, and animals, according to a new NOAA report.
