The oceans of the world absorb the overwhelming majority of the heat caused by global warming, creating serious consequences for life in and around them, including humans.

More dangerous algae blooms

“Microorganisms like it hot,” Hans W. Paerl, professor of marine and environmental sciences at the University of North Carolina at Chapel Hill’s Institute of Marine Sciences, told CNBC. “The higher the temperature and the faster they grow, and so this really has been a boon to them.”

The organisms that can grow really quickly in hot ocean temperatures and cause harmful algae blooms include dinoflagellates and diatoms, which are also called sometimes called microalgae or red tide, and cyanobacteria, which is sometimes called blue-green algae.
