Sea life in 'peril' as ocean temperatures hit all-time high in San Diego

Between 1982 and 2016, the number of 'marine heatwaves' doubled, and likely will become more common and intense as the planet warms, study finds

Even the oceans are breaking temperature records in this summer of heatwaves. Off the California coast near San Diego, scientists in early August recorded all-time high seawater temperatures since daily measurements began in 1916.

"Just like we have heatwaves on land, we also have heatwaves in the ocean," said Art Miller of the Scripps Institution of Oceanography.
