PBS NewsHour Reporting Friday on Rising Sea Levels in Coastal Louisiana

On Friday, PBS NewsHour reporter Hari Sreenivasan will report on how rising sea levels in coastal Louisiana are threatening Native Americans' tribal lands.

Gulf Coast Vulnerable to Extreme Erosion in Category 1 Hurricanes

Seventy percent of the Gulf of Mexico shoreline is vulnerable to extreme erosion during even the weakest hurricanes, according to a new report by the U.S. Geological Survey released just prior to the start of the 2012 hurricane season.

Bark Beetle May Impact Air Quality and Climate

At national parks out West, lodgepole pine trees are dying because of bark beetle. And atmospheric haze, caused in part by tiny solid particles suspended in the air, is becoming a problem.

New Species Top 10 List Draws Attention to Diverse Biosphere

The International Institute for Species Exploration at Arizona State University and a committee of scientists from around the world announced their picks for the top 10 new species described in 2011.

Environment Influences Behavior Generations Later

Researchers at The University of Texas at Austin and Washington State University have seen an increased reaction to stress in animals whose ancestors were exposed to an environmental compound generations earlier.

Study Compares Toxin Levels in Captive and Wild Sea Mammals

Amid growing concerns about the spread of harmful mercury in plants and animals, a new study by researchers from The Johns Hopkins University and The National Aquarium has compared levels of the chemical in captive dolphins with dolphins found in the wild.

Maine DEP and Coast Guard to Test Marine Spill Response on Damariscotta River

Responders from the Maine Department of Environmental Protection, the US Coast Guard and Moran Environmental Recovery will participate in a boom deployment exercise on the Penobscot River on Tuesday, May 22 and Wednesday, May 23.

Humanmade Pollutants May Be Driving Earth's Tropical Belt Expansion

Black carbon aerosols and tropospheric ozone, both humanmade pollutants emitted predominantly in the Northern Hemisphere's low- to mid-latitudes, are most likely pushing the boundary of the tropics further poleward in that hemisphere, new research by a team of scientists shows.



Nearly One Tenth of Western Hemisphere Mammals Unlikely to Outrun Climate Change

A safe haven could be out of reach for 9 percent of the Western Hemisphere's mammals, and as much as 40 percent in certain regions, because the animals just won't move swiftly enough to outpace climate change.

Push from Mississippi Kept Deepwater Horizon Oil Slick Off Shore

When the Deepwater Horizon drilling rig exploded April 20, 2010, residents feared that their Gulf of Mexico shores would be inundated with oil. And while many wetland habitats and wildlife were oiled during the three-month leak, the environmental damage to coastal Louisiana was less than many expected, in part because much of the crude never made it to the coast.

U.S. Fish and Wildlife Service Seeking Ideas to Strengthen Incentives for Wildlife Conservation

The U.S. Fish and Wildlife Service today announced the extension of a public process exploring the expansion of incentives for voluntary partnerships with private landowners and other land stewards to help conserve imperiled wildlife.

Nanotube Sponge has Potential in Oil Spill Cleanup

Carbon nanotubes, which consist of atom-thick sheets of carbon rolled into cylinders, have captured scientific attention in recent decades because of their high strength, potential high conductivity and light weight. But producing nanotubes in bulk for specialized applications was often limited by difficulties in controlling the growth process as well as dispersing and sorting the produced nanotubes.

Study Says Wind Can Carry Away Soil Particles That Help Build Soil and Recycle Nutrients

It was all too evident during the Dust Bowl what a disastrous impact wind can have on dry, unprotected topsoil. Now a new study has uncovered a less obvious, but still troubling, effect of wind: Not only can it carry away soil particles, but also the beneficial microbes that help build soil, detoxify contaminants and recycle nutrients.

Plastic Trash Altering Ocean Habitats

A 100-fold upsurge in human-produced plastic garbage in the ocean is altering habitats in the marine environment, according to a new study led by a graduate student researcher at Scripps Institution of Oceanography at UC San Diego.

Warming Affects Ecosystems Not Just Biodiversity

Ecosystems perform important tasks – like nutrient cycling, breakdown of waste and carbon storage – on which humans depend, so it's important we understand how climate change might affect them.

Study Shows Antarctic Waters Changing due to Climate

The densest waters of Antarctica have reduced dramatically over recent decades, in part due to man-made impacts on the climate, Australian scientists said Friday.

Lightning Signature Could Help Reveal Solar System Origins

An electromagnetic signature called the Schumann Resonance could be used to study other planets besides Earth in the solar system and could shed light on how the solar system formed, according to a paper published in the Astrophysical Journal.

Global Change Puts Plankton Under Threat

Changes in the ocean’s chemistry, as a result of increasing atmospheric carbon dioxide (CO2) levels, threaten marine plankton to a greater extent than previously thought, according to new research.

Scientists Core Into Clear Lake in California to Explore Past Climate Change

Scientists at University of California, Berkeley, will begin drilling into ancient sediments at the bottom of Northern California's Clear Lake to look at how today's plants and animals will adapt to climate change and increasing population.

Ecosystem Effects of Biodiversity Loss Could Rival Impacts of Climate Change and Pollution

Biodiversity loss could impact ecosystems as much as climate change, pollution and other major forms of environmental stress, according to a new study by an international research team.
