What warmer oceans mean for the planet


“That doesn’t sound like much, but there are many large cities around the world, much built on reclaimed land, that are not more than 30cm above sea level,” says Stephen Simpson, associate professor in marine biology and global change at the University of Exeter, in the UK.


But on top of that, warming oceans are causing polar ice sheets to melt faster, which will make sea levels rise even more.


Hurricane Harvey, which brought more than 1.5 meters (60 inches) of rain over four days in late August 2017, was made worse by unusually warm ocean temperatures.


“We’ll probably be seeing redistributing of water vapor in the atmosphere,” says Brad Linsley, research professor Columbia University’s Lamont-Doherty Earth Observatory.


This leads to plankton blooms and ultimately causes some parts of the sea to be starved of oxygen, making it hard for fish to live there.


“The Inuit living in Canada, for example, is a culture based on sea ice,” says Arnaud Czaja, a reader in physical oceanography at Imperial College London.
