Rsing ocean temperatures are rising in the northeast Pacific, similar to conditions presented in 2015. It is safe to say the marine heatwave known as the “Blob” has returned. This time the Blob’s 2019 return is the second largest to occur in the Pacific in at least 40 years. It encompasses 4 million square miles from Alaska to Canada and as far away as Hawaii, according to the National Oceanic and Atmospheric Administration. Nick Bond is quoted.
