The Arctic sea ice's typical winter expansion has been sluggish in 2016-17. Following a record-low January extent, this year's winter maximum may wind up being the smallest on record.

Increasing air and sea surface temperatures, decreasing sea ice extent and Greenland ice sheet mass, and changing behavior of fish and walrus are among key observations released today in the Arctic Report Card 2015.

The Greenland 2014: Follow the Water video is about Greenland's ice sheet, accompanied by computer models of the same, to show how the ice is melting, where the meltwater is going, and what it is doing both on the surface and beneath the ice.

This activity uses a mix of multimedia resources and hands-on activities to support a storyline of investigation into melting sea and land ice.

In this activity, students consider Greenland reflectivity changes from 2000 to 2012 and what albedo anomalies may indicate about how the Greenland ice sheet is changing in a case study format.

This NBC Learn video features climate scientists doing their research on Mt. Kilimanjaro to study the climate of the past. The scientists put the recently observed changes on the glacier into perspective by comparing past climate fluctuations, stressing that the current observed rate of change is unprecedented.

This video contains a visualization and explanation of the Arctic sea ice and how it has changed over the 25 years. In September 2012, the National Snow and Ice Data Center recorded the lowest extent of Arctic sea ice. The video discusses the climate importance of ice thickness, reflective properties, and self-reinforcing feedback mechanisms.

This video provides an overview of changes happening in the Arctic.

This NASA video discusses the impacts of the sun's energy, Earth's reflectance, and greenhouse gases on the Earth System.
