The current outbreak, which began in October 2017 off southwest Florida, has been tied to a record 589 sea turtle deaths and 213 manatee deaths, the Herald-Tribune reported, citing figures from the Florida Fish and Wildlife Conservation Commission.
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).
Australia's petroleum regulator granted permission for seismic blasting in the Great Australian Bight, sparking fierce outcry from environmentalists over its threat to the area's marine life, whihc include endangered blue and southern right whales.
On Monday, the National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA) gave the green light to oil and gas exploration services company PGS Australia's application for seismic surveys off the coast of South Australia's Kangaroo Island and Eyre Peninsula between Sept. 1 and Nov. 30 this year.
The results of what researchers say is the longest-running study of Antarctica's ice mass have been published, and they are dramatic. Yearly ice loss has increased by a factor of six in the past 40 years, contributing more than half an inch to global sea level rise, a University of California, Irvine (UCI) press release reported. The researchers also observed consistent ice loss from East Antarctica, which boasts the world's largest ice sheet and has traditionally been assumed to be more stable.
"The places undergoing changes in Antarctica are not limited to just a couple places," lead author and UCI chair of earth system science Eric Rignot told The Washington Post. "They seem to be more extensive than what we thought. That, to me, seems to be reason for concern."

The climate is changing faster than many species can adapt, so scientists are trying to speed up evolution by fostering the spread of creatures who can take the heat. Think of it as natural selection with a little boost from humans—or, in some cases, robots.
Sea Shepherd released a video showing fishermen shouting, hurling objects and trying to foul the propellors of the M/V Farley Mowat, a Sea Shepherd vessel used in campaigns against illegal fisheries activities.
An analysis of four recent studies of ocean temperatures has corrected some of the discrepancies between climate models that projected higher levels of ocean warming and observational data that turned up lower temperatures, concluding that the higher numbers were right.
Bluefin tuna made the news this week when a 612-pound specimen of the fascinating but vulnerable fish sold for a record $3.1 million at a New Year's auction at Tokyo's Toyosu fish market Saturday. The purchaser was Japanese sushi chain owner and self-proclaimed "Tuna King" Kiyoshi Kimura.
"The tuna looks so tasty because it's fat and (looks) very fresh. It is a good tuna. But I think I did too much," Kimura said, as CNN reported.

As human industry belches out more carbon dioxide, the chemistry of our oceans is changing. The resulting acidification is endangering coral reefs and the myriad creatures that depend on them. Science writer and one-time ocean researcher Juli Berwald wondered how ocean acidification affects jellyfish. Will they be climate change winners or losers?
