The first study to look systemically at marine heat waves — periods when ocean temperatures spike for five days or more —found that they are happening more often, and are having a devastating impact on marine life, The Guardian reported.
The paper, published in Nature Climate Change Monday, found that the number of heat wave days per year had increased by more than 50 percent during the last 29 years (1987 to 2016) when compared to the years between 1925 and 1954. This is bad news for important ocean ecosystems from kelp forests to coral reefs.
"The impact of this oil spill will have a devastating effect on the surrounding environment, including potentially on a protected UNESCO World Heritage Site, as well as the livelihood of the people of Rennell," Australia's High Commissioner to the Solomon Islands Rod Brazier said in a statement.

The world's oceans are heating up. Scientists have found that 2018 was the hottest year ever recorded for our oceans, and that they are warming even faster than previously thought.
When documenting global warming trends, we often focus on air temperature. But the oceans actually absorb more than 90 percent of the excess heat trapped by human emissions of greenhouse gases. So if we really want to know how much our planet is warming up, we look to the oceans.
That is because the Great Barrier Reef Marine Park Authority (GBRMPA) has approved plans to dump one million tonnes (approximately 1.1 million U.S. tons) of sludge into the World Heritage Site. The decision comes in the same month that runoff from flooding in Queensland, Australia threatened to smother part of the reef and two years after the unique ecosystem was weakened by back-to-back coral bleaching events caused by climate change.
In a case watched closely both by polluting industries and clean water advocates across the nation, the U.S. Supreme Court agreed to take up an appeal of a Clean Water Act case out of Hawaii concerning treated sewage flowing into the Pacific Ocean from injection wells.
The 740 foot MV Solomon Trader was stranded on a reef near Rennell Island, home to the largest raised coral atoll in the world and a United Nations Educational, Scientific and Cultural Organization (UNESCO) World Heritage site, AFP reported. The bulk carrier has not been salvaged in the two weeks since it was stranded because of Cyclone Oma, Solomon Islands National Disaster Management Office (NDMO) director Loti Yates told Radio New Zealand early Monday morning.
Muddy water from historic flooding in Queensland, Australia is now flowing out of rivers into the sea, threatening even the outer shelves of the Great Barrier Reef some 60 kilometers (approximately 37.3 miles) from the coast, Australia's ABC News reported Friday.
Australian Institute of Marine Science (AIMS) water quality team leader Dr. Frederieke Kroon told ABC News that the runoff covered "an extraordinarily large area." Researchers said it is likely filled with nitrogen pollution and pesticides, and poses a risk to the health of a reef already damaged by back-to-back coral bleaching events in 2016 and 2017.
The Florida Keys is home to the third largest living coral barrier reef system in the world. The ecosystem is a habitat for fish species and other marine life and also serves as economically important touristic and recreational spot.

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).
'Last Chance': Warming Could Be Limited to 1.5°C With Immediate Phaseout of Fossil Fuel Infrastructure, Researchers Say
It is still possible to limit global warming to 1.5 degrees Celsius above pre-industrial levels, a study published Tuesday in Nature Communications found, as long as we act immediately to phase out fossil fuels.
The study used a climate model to determine what would happen if, beginning at the end of 2018, all existing fossil fuel infrastructure—from industrial equipment to cars to planes to ships to power plants—was replaced with renewable alternatives at the end of its design lifetime. The researchers found there would be a 64 percent chance of limiting warming to 1.5 degrees, in line with the most ambitious goal of the Paris agreement.
