In the past three weeks three harsh nor’easter storms have battered the northeastern U.S., bringing the total to five for the winter. A sixth may be forming this week, which is highly unusual. Four of the five storms were bomb cyclones, a legitimate technical term that means the atmospheric pressure within the nascent storms dropped rapidly and radically, causing them to “blow up” into raging beasts.
Scientists have been predicting these very circumstances. And now they have new data showing that the rapidly warming Arctic is at least partly to blame.
