"One-hundred-foot-tall waves can be nightmarish ship-swallowing monsters — or seductive sirens that tempt the adventurous. But it wasn't until 15 years ago that scientists were even able to prove that such giant rogue waves actually existed."

"Scientists on a research vessel in the Gulf of Mexico are finding a substantial layer of oily sediment stretching for dozens of miles in all directions. Their discovery suggests that a lot of oil from the Deepwater Horizon didn't simply evaporate or dissipate into the water — it has settled to the seafloor."

"A plan to ship 16 steam generators on the Detroit River and Great Lakes has sparked an international outcry. What alarms residents on the U.S. and Canadian sides of the waterways is the material inside the generators -- nuclear waste."

"A far-reaching federal program of research and analysis, funded by Congress and designed to help the nation anticipate and temper the mounting conflict between rising energy demand and diminishing supplies of fresh water, has been brought to a standstill by the Department of Energy, according to government researchers involved in the project."

"Regulators who are supposed to police offshore oil and gas drilling are spread too thinly, poorly trained and hampered by outdated technology, according to a study by an Interior Department review board appointed after the BP oil disaster in the Gulf of Mexico."

"The world should safeguard coral reefs with networks of small no-fishing zones to confront threats such as climate change, and shift from favoring single, big protected areas, a U.N. study showed."
