Our Oceans Are Warming At An Even Faster Rate Than We Anticipated

These results demonstrate that earlier claims of a global warming slowdown since 2004 weren't necessarily accurate, since heat trapped from greenhouse gases has increased ocean temperatures.

The new analysis, published in Science, shows that trends in ocean heat content match those predicted by leading climate change models, and that overall ocean warming is accelerating.

Prior to Argo, ocean temperature data was sparse at best, relying on devices called expendable bathythermographs that sank to the depths only once, transmitting data until settling into watery graves. Together these advances have enabled quality reconstructions of the past ocean temperature record back to about 1960, enabling the context of the record-breaking recent observations to be properly established.

The findings in the United States journal Science, led by the Chinese Academy of Sciences, debunk previous reports that suggested a so-called pause in global warming in recent years.

The world's oceans are warming at an accelerated rate and are much warmer than scientists thought - and things could get a lot worse if nothing is done to stop climate change, according to anew study. 2018 is likely to be the hottest year for the oceans on record, beating out 2017 which held the record.

"The ocean is the memory of climate change, along with melted ice, and 93% of the Earth's energy imbalance ends up in the ocean", said study co-author Kevin Trenberth, part of the Climate Analysis Section at the US National Center for Atmospheric Research. "And so the first effect will be that sea level will be different in different places depending on the warming".

The Science report linked the warming to more rain, increased sea levels, coral reef destruction, declining ocean oxygen levels and declines in ice sheets, glaciers and ice caps in polar environments.

In fact, these scientists say records for ocean warming have been broken nearly yearly since the year 2000.

The study authors say the warming is happening because of climate change created by such human activities as the burning of fossil fuels.

"If the ocean wasn't absorbing as much heat, the surface of the land would heat up much faster than it is right now", Malin Pinsky, an associate professor in the department of ecology, evolution and natural resources at Rutgers University, told The New York Times. "There is no doubt, none", the scientists said in their new study on ocean warming.

Cheng explained that oceans are the energy source for storms, and can fuel more powerful ones as temperatures - a measure of energy - rise. And, unlike surface temperatures, ocean temperatures are not affected by year-to-year variations caused by climate events like El Nino or volcanic eruptions.
