Increasing Arctic freshwater is driven by climate change (CU Boulder Today)

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. That’s bad news for permafrost and the climate

July 24, 2020

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’s global climate.

Researchers find that heavy snowmelt plus usually warm temperatures amped up Oroville Dam incident

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.

Why a ‘feverish’ Arctic will affect everyone on the globe (PBS News Hour)

June 26, 2020

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.
