2018 Was the Hottest Year Ever Recorded for the Planet’s Oceans

Do you remember how hot the ocean got this past August at the beach? During the first week of that month, Scripps Pier recorded 3 days of warm water that set records. On Wednesday, August 1, Scripps Pier recorded the highest ocean surface water temperature in its 102 history of taking measurements.

The water temperature was 78.6 degrees. According to the National Ocean and Atmospheric Administration, the “normal” August average water surface temperature at the pier is 68 degrees.

Then, that Friday – and for the second time in the week – the ocean temperature reached an all-time high at Scripps Pier in La Jolla, hitting 78.8 degrees. On Sunday, the sea surface temperature hit 79.4 degrees.

Scientists at Scripps have been taking daily measurements at the pier since 1916.

And now we find out 2018 was the hottest year for the planet’s oceans. It was no surprise to those keeping track of such things. See this report from EcoWatch:

The year 2018 was the hottest year for the planet’s oceans ever since record-keeping began in 1958, according to a worrisome new study from international scientists.

The findings, published Wednesday in the journal Advances in Atmospheric Sciences, noted that the five warmest years for our oceans were the last five years—2018, 2017, 2015, 2016 and 2014 (in order of decreasing ocean heat content).

This increase in ocean heat is “incontrovertible proof that the Earth is warming,” the study states.

To illustrate, the heat increase from 2017 to 2018 alone is roughly 388 times more than China’s total electricity generation in 2017, according to a press release of the study.

“The new data, together with a rich body of literature, serve as an additional warning to both the government and the general public that we are experiencing inevitable global warming,” lead author Lijing Cheng, an oceanographer from the Beijing’s Institute of Atmospheric Physics, Chinese Academy of Sciences, said in the release.

A slew of recent scientific reports have sounded the alarm on our warming oceans. The same group of scientists behind the current study revealed in Science last week that the world’s oceans are warming about 40 percent faster than previously thought.

Also this month, a different team of scientists showed in the Proceedings of the National Academy of Sciences that the average heating of the oceans in the last 150 years was equivalent to the dropping of 1.5 atomic bombs per second.

Earth’s seas, which absorb more than 90 percent of the extra solar energy trapped by greenhouse gasses, are vital to our existence. This continued ocean warming has potentially devastating consequences, including sea level rise, stronger and wetter storms and melting polar ice. Marine life, especially coral reefs, are also vulnerable.

“The ocean and global warming have already taken place and caused serious damage and losses to both the economy and society,” Cheng said in the press release.

The researchers, who predict that ocean heat will continue to rise, urged immediate action to slow this alarming trend.
