The injured count is up to 77 and a 29-year-old man is dead after a chemical explosion in Geismar, La. Thursday.
300 people were evacuated from the Williams Olefins plant, which produces over a billion pounds of propylene and ethylene a year for use in the production of other chemical and plastic products. It was propylene that caught fire after the explosion. Ten workers stayed behind to monitor a burn-off.
The Bracken Bat Cave, just north of San Antonio, is as rural as it gets. You have to drive down a long, 2-mile rocky road to reach it. There's nothing nearby — no lights, no running water. The only thing you hear are the katydids.
The cave houses a massive bat colony, as it has for an estimated 10,000 years. Bat Conservation International, the group that oversees the Bracken Cave Reserve, wants it to stay secluded, but the area's rural nature could change if a local developer's plan moves forward.
BP is ending its cleanup of the massive Deepwater Horizon oil spill in three Gulf Coast states this month, leaving Louisiana as the only state with ongoing cleanup linked to the company's Deepwater Horizon Response effort. Reports of oil sightings in Alabama, Mississippi, and Florida will soon be the U.S. Coast Guard's responsibility to investigate.
The fear of something like a major oil spill in environmentally sensitive waters comes as the number of vessels plying the world's oceans has risen 20 percent in the past 15 years, from 85,000 to 105,000, the report, released on World Oceans Day, says.
Tropical Storm Andrea, the first named storm of the new hurricane season, has formed in the eastern portion of the Gulf of Mexico. Forecasters expect the storm to bring heavy rains to Florida before moving up the East Coast.
Hurricane season begins Saturday, and the National Oceanic and Atmospheric Administration is forecasting an active season, with perhaps seven to 11 hurricanes.
With memories of last year's destruction from Hurricane Sandy still fresh, meteorologists are working on ways to improve how they forecast storms and communicate warnings to the public.
When Sandy was making its way northward in the Atlantic and began to turn toward the East Coast, the National Hurricane Center tried to emphasize the danger that storm surge posed for residents, especially those near New York City.
Cities like Houston are dotted with air-sniffing monitors that measure levels of benzene and other potentially unhealthy air pollutants. But those monitors can't answer the question we care about most: Is the air safe?
That's because there's no simple relationship between toxic air pollutants and health risks. Researchers at the University of North Carolina in Chapel Hill are trying to get a leg up on that problem. They are building an instrument that uses human lung cells to measure health hazards in the air more directly.
