2018 Was the Hottest Year Ever Recorded for Our Oceans
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.

My wife and I built a house two years ago on a few acres of woodland outside of Pittsburgh. The backyard is full of maples, poplars, briars and common spicebush. Two-lined salamanders and grumpy-looking crayfish wade among the rocks in the small stream that runs down the edge of the property. Deer, raccoon and opossum tracks appear regularly in the snow and mud. Sometimes, my trail-cam even catches a pair of gray foxes as they slink through the night.

No matter the time of year, there's always a point in each season when my skin decides to cause me issues. While these skin issues can vary, I find the most common issues to be dryness, acne and redness.

Now, correspondence obtained by the LA Times revealed just how deeply involved industry lobbyists and a controversial, industry-funded toxicologist were in drafting the federal agency's proposal to scrap its current, protective approach to regulating toxin exposure.
February 22 is the birthday of conservationist and beloved TV personality "Crocodile Hunter" Steve Irwin, who would have been 57 years old today.
Irwin's life was tragically cut short when the barb from a stingray went through his chest while he was filming in 2006, but his legacy of loving and protecting wildlife lives on, most recently in a Google Doodle today honoring his birthday.
