According to the cover article in today’s issue of the journal Nature, the iconic reef off the coast of Australia suffered unprecedented coral die-off after last year’s record-breaking bleaching event. Now, as the Southern Hemisphere hits late summer temperatures, central and southern sections of the reef — areas which avoided the worst of last year’s bleaching — are in trouble.
“We didn’t expect to see this level of destruction to the Great Barrier Reef for another 30 years,” coral researcher Terry Hughes told the New York Times. Hughes led the team that conducted aerial surveys to document the bleaching last year, as well as subsequent surveys to assess just how much of that bleaching turned into dying.
Bleached corals don’t always turn into dead corals — some are able to recover when temperatures drop. Er, if temperatures drop. If water temperatures stay high and corals stay bleached, they will eventually starve to death. Without coral building reefs, whole ecosystems may disappear, along with the food, tourism, and jobs they support.
Hughes and his coauthors found that even corals in pristine, protected water were likely to be suffering from heat stress, meaning the only thing left to do to protect corals is, you know, address climate change.
In the summer of 2015, Metropolis Magazine named Pittsburgh one of the world’s “most livable” cities and gushed about its infrastructure, “The city has more vertical feet of public stairways than San Francisco, Cincinnati and Portland, Oregon, combined.” But the magazine hadn’t done its research. Around the same time, the city’s water utility was laying off employees in an effort to cut costs. By the end of the year, half of the staff responsible for testing water throughout the 100,000-customer system was let go. The cuts would prove to be catastrophic. Six months later, lead levels in tap water in thousands of homes soared. The professor who had helped expose Flint, Michigan’s lead crisis took notice, “The levels in Pittsburgh are comparable to those reported in Flint.” The cities also share something else, involvement by the same for-profit water corporation. Pittsburgh’s layoffs happened under the watch of French corporation Veolia, who was hired to help the city’s utility save money. Veolia also oversaw a change to a cheaper chemical additive that likely caused the eventual spike in lead levels. […]
