Ocean heatwaves

Most of the heatwaves we have experienced have been on land; there have been many fewer on the ocean. Scientists are wondering whether this pattern will continue, particularly since ocean heatwaves have doubled in frequency over the past few decades. Land heatwaves are much smaller in size, and they do not last as long. The scientists' concern was triggered by what they call "the blob". This was a heatwave triggered by El Nino. It lasted from 2103 to 2015 and resulted in killing a million birds the scientists think. It went from California to Alaska.

Not only did tons of birds die, the birds did not produce many chicks.
