The world's oceans are now heating at the same rate as if five Hiroshima atomic bombs were dropped into the water every second, scientists have said.

A new study released on Monday showed that 2019 was yet another year of record-setting ocean warming, with water temperatures reaching the highest temperature ever recorded.

An international team of 14 scientists examined data going back to the 1950s, looking at temperatures from the ocean surface to 2,000 meters deep. The study, which was published in the journal Advances in Atmospheric Sciences, also showed that the oceans are warming at an increasing speed.

Tiny pieces of plastic have been found in ice cores drilled in the Arctic by a U.S.-led team of scientists, underscoring the threat the growing form of pollution poses to marine life in even the remotest waters on the planet . . . 

 . . . The team plans to subject the samples to further analysis to support a broader research effort to understand the damage plastic is doing to fish, seabirds and large ocean mammals such as whales . . .

 . . . much of the large amounts of microplastic found in the Arctic in previous studies had probably been carried there through the atmosphere.

“Once we’ve determined that large quantities of microplastic can also be transported by the air, it naturally raises the question as to whether and how much plastic we’re inhaling,” Bergmann said in a statement.

The faster the ocean warms, the faster key Antarctic glaciers will disintegrate.

A stunning new study on Antarctic sea ice collapse greatly raises the risk of a 10-foot sea level rise this century if President Donald Trump’s climate policies aren’t quickly reversed.

Warming ocean waters drove a 6-fold increase in annual ice mass loss from the Antarctic ice sheet between 1979 and 2017, according to a new study in the Proceedings of the National Academy of Sciences.

It’s been known for a while that the West Antarctic Ice Sheet (WAIS) was unstable and collapsing at an accelerating rate due to global warming. But the new study finds that parts of the vastly larger East Antarctic Ice Sheet (EAIS) are also disintegrating.
