Ocean temperatures were at a record high in 2018

Climate change and ocean warming

Using new analysis for the upper 2 thousand metres of the world’s oceans,

it was found that ocean temperatures were at a record high in 2018.

The last five years have been the hottest ocean temperatures on record.  

Ocean warming has been accelerating since the 1990s.

Ocean warming is faster than predicted

More than 90 percent of heat trapped by greenhouse gas emissions

accumulates in the ocean. Scientists found agreement among multiple lines

of temperature measurements that the world’s oceans have been warming

about 40 percent faster than the Intergovernmental Panel on Climate Change

estimated in the Fifth Assessment Report of 2014.
