In early January 2014, an Arctic air outbreak brought extreme cold and heavy snowfall to central and eastern North America, causing widespread disruption and monetary losses. However, new research using state-of-the-art climate model simulations finds that the risk of North American daily cold extremes decreases in the future.
Extreme precipitation and associated flooding has a high societal and economic cost. In the Northeast US extreme precipitation has increased by more than 70% in the last 50 years and is projected to continue to increase.
As of spring 2015, a wide strip of relatively warm water was present along the entire West Coast of North America. The causes and effects of this warm ocean water event is sometimes referred to as the “blob” and are the results of a new paper in Geophysical Research Letters.
