Deep in the northeast Pacific Ocean, The Blob is acting strangely.
When the abnormally warm patch of water first appeared in 2013, fascinated scientists watched disrupted weather patterns, from drought in California to almost snowless winters in Alaska and record cold winters in the northeast.
The anomalously warm water, with temperatures three degrees Centigrade above normal, was nicknamed The Blob by U.S climatologist Nick Bond. It stretched over one million square kilometres of the Gulf of Alaska — more than the surface area of B.C. and Alberta combined — stretching down 100-metres into the ocean.
