Increasing Arctic freshwater is driven by climate change

New, first-of-its-kind research from CU Boulder shows that climate change is driving increasing amounts of freshwater in the Arctic Ocean. Within the next few decades, this will lead to increased freshwater moving into the North Atlantic Ocean, which could disrupt ocean currents and affect temperatures in northern Europe. The paper, authored by Alex Jahn and Rory Laiho and published in Geophysical Research Letters, examined the unexplained increase in Arctic freshwater over the past two decades and what these trends could mean for the future.
