A new study, led by Alexandra Jahn, shows increased precipitation and ice melt caused by climate change have left Arctic waters less salty. Repercussions will be felt much farther south.

Data from ice cores can show not only what Earth was like in prehistoric times, but how the mechanisms of climate work and how our climate may transform in the near future. INSTAAR research scientist Tyler Jones led an effort to synthesize ideas about the most meaningful, impactful questions that researchers might answer using ice cores from Antarctica. The result is a white paper that lays out priorities for ice core work in Antarctica for the next five to ten years.

New, first-of-its-kind research from Rory Laiho and Alex Jahn shows that climate change is driving increasing amounts of freshwater in the Arctic Ocean, which will lead to increased freshwater moving into the North Atlantic Ocean, which could disrupt ocean currents and affect temperatures in northern Europe.

Alaska is getting wetter. A new study spells out what that means for the permafrost that underlies about 85% of the state, and the consequences for Earth鈥檚 global climate.

Minority, tribal, and indigenous people are the most vulnerable to climate change. INSTAAR Keith Musselman is quoted in this Powder Magazine story.

In February 2017, failures in the spillways of Oroville Dam forced the evacuation of 188,000 people and caused $1 billion in damage repairs. According to scientists, including INSTAARs Keith Musselman, Leanne Lestak, and Noah Molotch, a warmer climate might create more dangerous events like this.

The United States has always been a scientific powerhouse, but following a sudden announcement from ICE, some worry that 鈥渨e鈥檙e just going to get so far behind.鈥� Eos story quotes INSTAAR doctoral student Lina P茅rez-Angel.

Merritt Turetsky is quoted in a Washington Post story on the record-setting heat wave across Siberia that is leading to massive wildfires and permafrost melt.

Surface air temperatures at the bottom of the world have risen three times faster than the global average since the 1990s. Sharon Stammerjohn (INSTAAR) and Ted Scambos (NSIDC) are quoted about their commentary in Nature Climate Change.
