President Obama will honor Earth Day Wednesday by visiting the Florida Everglades, an area greatly affected by climate change. NPR’s Melissa Block talks to Florida International University ecologist Evelyn Gaiser about what damage has already been done to the region.
This month, the National Oceanic and Atmospheric Administration is flying an airborne research lab over oil and gas producing states.
An effort is underway to figure out how the BP oil spill harmed the Gulf of Mexico ecosystem. The damage may not be as dire as feared, but researchers say it’s too soon to know the long-term impacts.
(Reuters) – Oklahoma geologists have documented strong links between increased seismic activity in the state and the injection into the ground of wastewater from oil and gas production, a state agency said on Tuesday.

Our volunteers at Adventurers and Scientists for Conservation are exploring the farthest reaches of the globe, and sometimes, they accomplish amazing things. After years of sampling from high mountain lakes in the Pacific Northwest, the work of our hikers and climbers gathering water from alpine lakes has paid off.
Their samples provided the basis for ASC partner scientist Dr. Loren Bahls to discover a new genus of diatom.
This means that during a solo weekend backpacking trip in the Olympic Mountains, Washington, ASC adventurer Craig Weiland not only climbed Mount Deception, he was able to give back to conservation. Craig and others did this around the northwest, on trips to places including Crater Lake, Oregon, Montana’s Beartooth Mountains, and Yellowstone National Park.
Diatoms are essential to the health of the planet. These single-celled photosynthetic organisms form the base of nearly all aquatic food chains, and they account for around 40 percent of carbon fixation and oxygen production worldwide, according Dr. Bahls, who curates the Montana Diatom Collection.
“Diatoms appeared sometime during the Cretaceous, about the same time as flowering plants and when dinosaurs ruled the land,” explains Dr. Bahls. “When you slip on the rocks in a mountain stream, you are slipping on a thin layer of diatoms and the mucilage they produce.”
He named the new genus Kurtkrammeria after the German diatom researcher Kurt Krammer, and the new type species Kurtkrammeria weilandii (pictured at left) for Craig Weiland one of the most active volunteers on the project. Craig’s photos from his sampling adventures in the Cascades are featured in the slide show above.

A flu strain deadly to chickens and turkeys is striking farms in the West and Midwest. This week, it hit an Iowa facility with millions of egg-laying hens. No one knows how it’s entering houses.
