Oceans were hottest on record in 2019

Oceans absorb more than 90 percent of excess heat created by
greenhouse gas emissions and quantifying how much they have warmed up
in recent years gives scientists an accurate read on the rate of
global warming.

A team of experts from around the world looked at data compiled by
China's Institute of Atmospheric Physics (IAP) to gain a clear picture
of ocean warmth to a depth of 2,000 metres over several decades.

They found that oceans last year were by far the hottest ever recorded
and said that the effects of ocean warming were already being felt in
the form of more extreme weather, rising sea levels and damage to
marine life.

The study authors said there was a clear link between climate-related
disasters—such as the bushfires that have ravaged southeastern
Australia for months—and warming oceans.
Warmer seas mean more …. evaporative demand by the atmosphere. That in
turn leads to drying of the continents, a major factor that is behind
the recent wildfires from the Amazon all the way to the Arctic, and
including California and Australia."
Hotter oceans also expand, leading to sea level rises. And given that
the ocean has a far higher heat absorption capacity than the
atmosphere, scientists believe they will continue to warm even if
humanity manages to drag down its emissions in line with the Paris
goals.
