Rising Arctic temperatures have changed both wind patterns and precipitation in areas that carry dust to West and South Asia, but the change may not be permanent.

Cerrando la brecha entre las geociencias y la seguridad nacional
La comunidad de geociencias y las agencias de seguridad nacional necesitan una comunicación efectiva y bidireccional para intercambiar información.
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.
Convergence Science in the Arctic
Focusing on climate change and industrialization in Siberia’s Yamal Peninsula, researchers developed science questions that aim to reach far beyond any single discipline.
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.
Northern Permafrost Region Emits More Greenhouse Gases Than It Captures
Permafrost underlies a quarter of the Northern Hemisphere. A comprehensive analysis shows that the area may have shifted from a sink to a source of greenhouse gases, bringing a longtime prediction to fruition.
Melting Ice in the Polar North Drives Weather in Europe
Influxes of meltwater into the North Atlantic eventually lead to warmer and drier conditions over Europe.
Climate Change Is Weakening River Seasonality in the North
Seasonal flow variability is decreasing as climate change alters Earth’s systems, creating challenges for water management.
Monitoring Polar Ice Change in the Twilight Zone
Landsat’s new extended data collection program is mapping Arctic and Antarctic regions year-round, even in polar twilight.
Bridging Gaps Between the Geosciences and National Security
The geoscience community and national security agencies need effective, two-way communication to exchange information.
