A mysterious anthrax outbreak over the summer killed more than 2,300 reindeer and at least one child.

Freak warm weather followed by a freeze in winter 2013-14 caused an ice-over of pastures which led to the deaths of some 70,000 reindeer in a famine. This summer, there was an outbreak of deadly anthrax after the hottest Arctic summer on record.

Ponds in and around the Nome area are drying up.

When 200 million metric tons of rock tumbled down a remote Southeast Alaska mountain in October, nobody was around to see it. But thanks to a beefed-up seismic network and a new system that can distinguish landslides from earthquakes, scientists knew it had happened.

Permafrost thawing causing bridge damage.

We performed a survey of community water lines to see how permafrost thaw and sinking foundations may be impacting homes, water and waste water systems. During the June visit we saw where foundation sinking was putting stress on pipe runs and junctions. Now in the winter we see evidence of freeze up in some of the homes where the junction boxes have been compromised, gaps in the insulation seal, and resulting freeze up and overflow of water.
