Human Emissions Made Ocean Heat Wave 53 Times More Likely

A National Geographic article discusses what caused three 2016 marine heat waves that killed whales, birds, corals, and shellfish from Australia to Alaska – climate change. 

Just as atmospheric shifts can bring droughts and nasty heat waves on land, shifts in weather or ocean circulation also can spark deadly marine heat waves, which can thoroughly scramble life at sea. But until recently scientists understood little about what role climate change might play in these extreme sea events.

Eric Oliver, an assistant professor of physical oceanography at Dalhousie University, co-authored a pair of studies examining all three events. The latest study was published in the Bulletin of the American Meteorological Society.
