New satellite instruments and data, plus a more comprehensive observing network, are key to increasing our understanding of past and future change in the Arctic Boreal Zone.

Using Satellites and Supercomputers to Track Arctic Volcanoes
New data sets from the ArcticDEM project help scientists track elevation changes from natural hazards like volcanoes and landslides before, during, and long after the events.
Reconstructing 150 Million Years of Arctic Ocean Climate
A new summary of past Arctic climate conditions gives insight into anthropogenic influences on today’s climate and on the need for future drilling studies to further improve our understanding of the past.
Where Does the Carbon Go When Permafrost Coasts Erode?
Arctic coastlines have not been considered carefully in carbon cycles for long, but new research suggests that eroding permafrost may emit more greenhouse gases than previously thought.
Permafrost Thaws Rapidly as Arctic River Flooding Increases
As climate warms, Arctic rivers carry higher flows and flood earlier in the spring, causing underlying permafrost to thaw rapidly.
Polar Stratosphere Resolves North Atlantic Jet “Tug of War”
Getting the polar stratosphere right is critical in the simulation of North Atlantic climate change, which is shaped by the interaction of Arctic Amplification and tropical upper tropospheric warming.
As Arctic Sea Ice Disappears, What Happens to Ecosystems?
The northern Bering Sea is experiencing record-setting low winter sea ice levels, which are impacting plankton, fish, and other animals in the region.
Turning the Arctic Brown
For a generation, the tundra has seen an increasing growth of vegetation, a process known as Arctic greening. A more accurate term might be “Arctic browning.”
House Passes Measure to Protect Arctic National Wildlife Refuge
The measure, which would repeal an oil and gas development program in the refuge, now needs to pass the Senate, where there is stiff opposition.
Is the Northern Permafrost Zone a Source or a Sink for Carbon?
Thawing permafrost could release large amounts of carbon into the atmosphere, but finding out how much requires better collection and curation of data.
