SNIP: Arctic winter warming events – winter days where temperatures peak above 14 degrees Fahrenheit (minus 10 degrees Celsius) – are a normal part of the climate over the ice-covered Arctic Ocean. But new research by an international team that includes NASA scientists finds these events are becoming more frequent and lasting longer than they did three decades ago.

A new study, published in Geophysical Research Letters on Jul. 10, shows that since 1980, an additional six warming events are occurring each winter in the North Pole region. The study also shows the average length of each event has grown from fewer than two days to nearly two and a half days.
