In the fall of 2014, Nick Bond—research scientist at JISAO and Washington State’s Climatologist—dubbed a patch of unusually warm water off the North American coast ‘The Blob’. The warmer temperatures went on to wreak havoc in marine environments over the following year. Now, another slug of warm water has appeared, this time stretching all the way to Hawaii. We sat down with Bond to talk about this new Blob—which is an anomaly in the ocean more commonly referred to as a ­marine heat wave—and what we might expect.
