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.
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.
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.
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.
In a "news and views" piece in Nature Climate Change, INSTAAR Sharon Stammerjohn and CIRES researcher Ted Scambos spell out the evidence and consequences of rapid warming at the South Pole and call for action to 鈥渇latten the curve鈥 of global carbon emissions.
A historic heat wave is occurring in the Arctic, already the fastest-warming place on Earth due to the increasing accumulation of greenhouse gases. Dr. Merritt Turetsky has studied the Arctic for decades. She joins William Brangham on PBS NewsHour to discuss causes and consequences of the Arctic's rising temperatures.
A new sampling method uses carbon-14 to single out which carbon dioxide molecules in the atmosphere derive from fossil fuels. The method could help track emissions goals for climate mitigation.
Arctic infrastructure is under threat from thawing permafrost, explains this story in Eos featuring Merritt Turetsky.
