During Low-Ice Seasons, Some Polar Bears Are Turning to Glacier Ice

As warming temperatures melt Arctic sea ice, glaciers act as supplemental habitat for a group of southeast Greenland polar bears looking to hunt during the low-ice season.

As Climate Stirs Arctic Sea Ice Faster, Pollution Tags Along

A warming climate is not just melting the Arctic’s sea ice; it is stirring the remaining ice faster, increasing the odds that ice-rafted pollution will foul a neighboring country’s waters, says a new study.

Scouring Arctic for Traces of Fukushima and Cosmic Rays

Sounds like the basis for a great scifi thriller…”scientists scour Arctic, hunting for traces of nuclear fallout and ejections from cosmic ray impacts”. In reality this thriller theme is the actual core of the GEOTRACES mission.

Moving into the Realm of the Polar Bear

When we venture into the Arctic for research for most of us there is the lingering hope that a polar bear will appear on our watch; at least as long as we are safely outside of its reach.

Studies Find Climate Change to Disrupt Antarctic and Tropical Ecosystems

A recent study finds that West Antarctica’s ecosystem is highly correlated to its climate. As a result, climate change will have a negative impact on its ecological relationships, from plankton to penguins. Antarctica isn’t alone – climate change will also affect tropical ocean ecosystems by causing mass coral bleaching.
