Oceans hotter than ever before

Ocean waters hit their highest temperature ever last year, and the rate at which they are warming is speeding up, a new study has revealed. Researchers called the new data "further proof of global warming." The world's oceans are warmer than ever and they are getting warmer faster, according to a new report. In a development that provides yet further evidence of global warming, the study, published in the Chinese journal Advances in Atmospheric Sciences , found that ocean temperatures in the last decade have been the warmest on record. In addition, the research illustrates the influence of human-induced warming on the Earth's waters and indicates that sea-level rise, ocean acidification and extreme weather could get worse as the oceans go on absorbing excess heat. 'Really dire news' "The pace of warming has increased about 500% since the late 1980s," John Abraham, one of the researchers behind the study, told NBC News. Abraham, who is a professor of thermal sciences at the University of St. Thomas in St. Paul, Minnesota, was not surprised by the results of the study. "The findings, to be honest, were not unexpected. Warming is continuing, it has accelerated, and it is unabated. Unless we do something significant and quickly, it's really dire news."

In the period between 1987 and 2019, warming accelerated at almost 4 1/2 times the rate observed in the period between 1955 and 1986, the report showed. Abraham and his colleagues found that in 2019 alone, average ocean temperatures were 0.075 degrees Celsius (0.135 degrees Fahrenheit) above the 1981-2019 median. While that may not seem a lot, it represents an enormous amount of heat spread across the world's oceans.

The increase in ocean temperature can have wide-ranging repercussions, for both sea and land life. Even the recent bushfires in Australia have been cited by experts as an example of the warmth in the oceans playing a devastating role inland .
