Researchers from the University of Washington have found that a giant “blob” of hot ocean in the Pacific killed almost one million seabirds between 2015 and 2016. Called common murres, the birds most probably died as a result of starvation.The heat blob was formed due to severe marine heatwave. Food grew scarce amid intense competition from other marine animals, causing a fight for survival. Other reasons for the deaths include a vast bloom of harmful algae along North America’s Pacific coast. The seabird has not replenished ever since.
