A new analysis, published Thursday in the journal Science, found that the oceans are heating up 40 percent faster on average than a United Nations panel estimated five years ago. The researchers also concluded that ocean temperatures have broken records for several straight years.
?2018 is going to be the warmest year on record for the Earth?s oceans,? said Zeke Hausfather, an energy systems analyst at the independent climate research group Berkeley Earth and an author of the study. ?As 2017 was the warmest year, and 2016 was the warmest year.?
As the planet has warmed, the oceans have provided a critical buffer. They have slowed the effects of climate change by absorbing 93 percent of the heat trapped by the greenhouse gases humans pump into the atmosphere.

?If the ocean wasn?t absorbing as much heat, the surface of the land would heat up much faster than it is right now,? said Malin L. Pinsky, an associate professor in the department of ecology, evolution and natural resources at Rutgers University. ?In fact, the ocean is saving us from massive warming right now.?
But the surging water temperatures are already killing off marine ecosystems, raising sea levels and making hurricanes more destructive.
As the oceans continue to heat up, those effects will become more catastrophic, scientists say. Rainier, more powerful storms like Hurricane Harvey in 2017 and Hurricane Florence in 2018 will become more common, and coastlines around the world will flood more frequently. Coral reefs, whose fish populations are sources of food for hundreds of millions of people, will come under increasing stress; a fifth of all corals have already died in the past three years.
People in the tropics, who rely heavily on fish for protein, could be hard hit, said Kathryn Matthews, deputy chief scientist for the conservation group Oceana. ?The actual ability of the warm oceans to produce food is much lower, so that means they?re going to be more quickly approaching food insecurity,? she said.
Because they play such a critical role in global warming, oceans are one of the most important areas of research for climate scientists. Average ocean temperatures are also a consistent way to track the effects of greenhouse gas emissions because they are not influenced much by short-term weather patterns, Mr. Hausfather said.
