August 6, 2013 The federal government's top climate scientists announced Tuesday that 2012 was really hot — among the top 10 hottest years on record and the hottest ever in the U.S., with rising sea levels, less Arctic sea ice and warmer oceans. And the American Geophysical Union called humanity "the major influence" on global climate change.
August 6, 2013 Dense forests of old-growth pines and cypress once blanketed South Carolina. As farming spread, nearly all the state's virgin trees were logged, but some sank into rivers en route to the sawmills. Now, some entrepreneurs are raising the preserved trees from the muck — and selling them for big money.

August 5, 2013 KUNCThe world's soil is in trouble. Ecologists say without dramatic changes to how we manage land, vast swathes of grassland are at risk of turning into hard-packed desert. To make sure that doesn't happen, researchers are testing out innovative ways to keep moisture in the soil.
August 2, 2013 Paleontologists have been spending a lot of time studying the Earth of 50 million years ago, which was much hotter than it is today. They're hoping a glimpse into the planet's geologic past will show them how the planet will respond to all the carbon dioxide we're now putting into the air.
July 31, 2013 Oil developers in the Canadian Tar Sands are trying to understand some odd oil eruptions around several drilling platforms where oil is coming up through the ground rather than through the wells they drilled. The latest of these events tarred about 50 acres of forest.
July 29, 2013 KUTThe industry estimates that the U.S. will need to add 2,000 miles of pipeline per year, and that's just natural gas. Oil will need its own infrastructure. That means there will be a lot of pipeline going through a lot of private land — along with sometimes long, drawn-out legal fights with landowners.
July 29, 2013 Flossie could become the first tropical cyclone in recorded history to hit the Big Island head on. It is the first to make landfall on the islands since 1992.
July 29, 2013 KQEDThe Ivanpah Solar Electric Generating System in California's Mojave Desert will power about 140,000 homes and be a boon to the state's renewable energy goals. But it was no slam dunk. Now, California is trying to bring conservationists and energy companies together to create a smoother path for future projects.
July 28, 2013 Man-made noises are making it difficult for creatures to hear each other in the ocean. Michael Jasny, in charge of marine mammal protection the Natural Resource Defense Council, says we have to quiet down. His and other conservation groups are making their case, seeking ways to turn down the volume.
