World’s oceans are heating up at a quickening pace — study

TAMPA, United States (AFP) — The world’s oceans are heating up at an accelerating pace as global warming threatens a diverse range of marine life and a major food supply for the planet, researchers said Thursday.

The findings in the US Journal Science, led by the Chinese Academy of Sciences, debunked previous reports that suggested a so-called pause in global warming in recent years.

The latest technology shows no such hiatus ever existed, raising new concerns about the pace of climate change and its effect on the planet’s main buffer — the oceans.

“Ocean heating is a very important indicator of climate change, and we have robust evidence that it is warming more rapidly than we thought,” said co-author Zeke Hausfather, a graduate student in the Energy and Resources Group at the University of California, Berkeley.

About 93 per cent of excess heat — trapped around the Earth by greenhouse gases that come from the burning of fossil fuels — accumulates in the world’s oceans.

The latest report relied on four studies, published between 2014 and 2017, that gave more precise estimates of past trends in ocean heat, allowing scientists to update past research and hone predictions for the future.

A key factor in the more accurate numbers is an ocean monitoring fleet called Argo, which includes nearly 4,000 floating robots that “drift throughout the world’s oceans, every few days diving to a depth of 2,000 metres and measuring the ocean’s temperature, pH, salinity and other bits of information as they rise back up,” said the report.
