Petty, Boisvert co-authors of new Arctic winter warming study

ESSIC researchers Alek Petty and Linette Boisvert are co-authors of a new study that has determined that temperature peaks above minus 10 degrees Celsius are occurring more frequently during the arctic winter.  Titled “Increasing frequency and duration of Arctic winter warming events,” the study published in Geophysical Research Letters (GRL) has been featured by both the American Geophysical Union (AGU) and NASA’s Goddard Space Flight Center.  Although arctic winter warming events are a normal cyclical part of the Arctic climate, the new research finds the events are occurring more frequently and lasting longer than they did three decades ago.
