The world’s oceans were the hottest in recorded history in 2019, scientists said on Tuesday, as man-made emissions warmed seas at an ever-increasing rate with potentially disastrous effects on Earth’s climate.
They found that oceans in 2019 were by far the hottest recorded and said the effects of ocean warming were already being felt in the form of more extreme weather, rising sea levels and damage to marine life. “That’s roughly equivalent to everyone on the planet running 100 hairdryers or 100 microwaves continuously for the entire year,” Michael Mann, director of Penn State's Earth System Sciences Center, said.The 2015 Paris accord aims to limit global temperature rises to “well below” 2ºC, and to 1.5ºC if at all possible.
“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.”In a landmark oceans report in 2019, the UN Intergovernmental Panel on Climate Change warned that tens of millions of people could be displaced from coastal areas by the end of the century because of encroaching seas.
