Coral reefs aren’t just threatened by pollution, ocean acidification and over-heated ocean temperatures. In some places they are being undermined by erosion of the seafloor, U.S. Geological Survey scientists said in a new study that looked at reefs in Florida, the Caribbean and Hawaii.
In the five study sites, the reefs can’t keep pace with sea level rise. As a result, coastal communities protected by the reefs are facing increased risks from storms, waves and erosion.
The degradation of reefs and the subsiding seafloor go hand-in-hand, as sand and other sea floor materials have eroded over the past few decades. In the waters around Maui, the sea floor losses amounted to 81 million cubic meters of sand, rock and other material – about what it would take to fill up the Empire State Building 81 times, the researchers calculated.

Without expensive measures, some strands will vanish by 2100
Scientists are warily watching the impacts of rising sea levels along the world’s coastlines, where a high percentage of the global population lives and works. In some areas — especially narrow strands are pinned between the open ocean and coastal mountains, beaches may vanish by 2100 as higher waves and bigger storm surges wash away the precious sand.
Widespread support for climate action in 4 major European countries
The average global temperature spiked to yet another record in March 2016.
More than eight out of 10 people in the UK, France, Germany and Norway believe that the world’s climate is changing, and a similar proportion think that it is at least partly caused by human activity, according to a recent scientific survey conducted by European researchers.
Environmental protections are under attack on every front and the far North is no exception. Alaska’s senators Lisa Murkowski and Dan Sullivan, both Republicans, appear willing to risk fragile ocean environments for a few more petrodollars, so they’ve opportunistically introduced a bill that would expand oil and gas drilling in the Arctic Ocean and Cook Inlet, where a recent gas leak persisted for several months, according to InsideClimate News.
Senate Bill 883 seeks to reverse protections established by President Obama in Dec. 2016 and force the Department of the Interior to quickly approve new oil and gas leasing.
“It’s not possible to drill safely in the Arctic, as we just saw from the leaking oil and gas well on the North Slope,” said Miyoko Sakashita, ocean programs director at the Center for Biological Diversity. “This legislation’s nothing more than a giveaway to oil companies. It’ll hurt Alaska’s healthy habitat and endangered wildlife.” Continue reading “Alaska’s senators want more offshore drilling in Arctic waters”→
Nothing says Easter like a visit to the country to check out trees bursting into bloom and other signs of nature’s spring resurgence. It’s a good reminder that when you strip away the bizarre Christian mythology surrounding this holiday, what you have left is a good old-fashioned pagan celebration of life. And nothing could be more glorious than that because it’s the life-force of nature that’s at the basis of our reality, not some musty legends handed down over generations by a secretive theocractic organization.
EPA administrator Scott Pruitt may have to back up his false claims on greenhouse gases and climate change in court. A lawsuit filed April 13 by the watchdog group Public Employees for Environmental Responsibility wants the agency head to show studies backing up his statements that call into question the role of CO2 emissions in global warming. The lawsuit also seeks to determine whether EPA possesses a single study that supports Mr. Pruitt’s stance. Continue reading “EPA chief sued for ‘spouting deceptive climate pseudo-science’”→
Road salt, development blamed for spiking chloride levels
Lakes from New England to the Midwest are getting saltier from the massive use of chemicals to melt ice on roads, as well as from urban development. Under the current trend, many North American lakes will surpass EPA-recommended chloride levels in 50 years, spelling trouble for aquatic ecosystems.
