Saturday, June 8 is World Oceans Day, a chance to honor and celebrate our blue planet. Ocean lovers around the world will attend beach cleanings and other events or join a March for the Ocean to call for an end to activities that harm marine life, like offshore oil drilling and plastic pollution.
'Social Breakdown and Outright Chaos': Civilization Headed for Collapse by 2050, New Climate Report Warns
A new report warns that climate change could displace more than a billion people, leave two billion without regular water access and lead to a breakdown in international order by 2050 if nations do not increase their commitments under the Paris agreement.
"Climate change now represents a near- to mid-term existential threat to human civilization," the report authors conclude.

The study, published in the Journal of the American Medical Association Monday, found subjects' blood had levels of avobenzone, oxybenzone, octocrylene and ecamsule substantially above the 0.5 nanograms per milliliter (ng/mL) point at which testing is required. One of the chemicals, oxybenzone, has been shown to harm coral reefs, and sunscreens containing it have been banned in coral habitats from Hawaii to Key West, Florida.
Coral Reefs Provide Flood Protection Worth $1.8 Billion Annually — Another Key Reason to Protect Them
By Michael Beck
The news is grim: According to a report compiled by hundreds of scientists from 50 countries, Earth is losing species faster than at any other time in human history. Thanks to climate change, coastal development and the impacts of activities such as logging, farming and fishing, roughly 1 million plants and animals are facing extinction.

An emerging concern among ocean scientists, stewards and beachgoers is the impact that certain chemical sunscreens are having on the marine environment. This has led to bans on the sale and use of chemical sunscreens in states and island communities such as Hawaii, Key West and Aruba, and a proposed federal ban in all U.S. National Marine Sanctuaries containing coral reefs. There has also been a surge in the production of "reef friendly" sunscreens — but what does that actually mean, and how safe are these alternative sunscreens to the marine environment?
‘Dead Corals Don’t Make Babies’: New Great Barrier Reef Coral Growth Declined 89% After Back-to-Back Bleaching Events
A study published in Nature Wednesday found that the death of corals in 2016 and 2017 has significantly decreased the ability of new corals to grow and thrive. In 2018, there has been an 89 percent decline in the number of new corals on the reef compared to the historic record.
"Dead corals don't make babies," lead author and James Cook University professor Terry Hughes said, as BBC News reported.
This month corals in Lord Howe Island Marine Park began showing signs of bleaching. The 145,000 hectare marine park contains the most southerly coral reef in the world, in one of the most isolated ecosystems on the planet.
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.
