Sometimes, nature knows the best way to solve a problem. There's a beetle that lives in a part of the world where less than .5 inches of rain fall per year. So the beetle draws water from the air, and now a businessman is trying to harness that idea to create, among other things, a self-filling water bottle.
John Fasullo's trying to get some of the uncertainty out of predicting climate change. He says many of our current models aren't accurate, and are being used to under-represent the consequences of our warming planet.
Ask Jennifer Francis about Hurricane Sandy and she'll point north. Ask her about this summer's midwestern drought, she'll point north, all the way to the Arctic. She's linked Arctic ice melting with fluctuations in global weather.
New Ken Burns documentary looks at Dust Bowl, 'worst sustained environmental disaster' in U.S. history
Ken Burns is widely celebrated for the incredible documentaries he brings to television. His latest work, set to air on PBS stations Nov. 18 and Nov. 19, looks at the conditions that led to the Dust Bowl -- an environmental disaster called the worst in our history, and how it happened.
Boston's Hubway bike sharing program is popular with commuters, who may use a bike to finish their commutes to their homes or offices. As the program in Boston looks to expand, bike sharing programs are taking hold in cities the world over.
Perhaps it should come as no surprise that the problems with the New York subway system after Hurricane Sandy came ashore led thousands of people to pick up a bike to get to work. But all those extra bike commuters were exposed to the success and failure of New York City's effort to be more bike-friendly.
Hurricane Sandy roared ashore in New York just two weeks ago, destroying the homes of the wealthy and the poor alike. Elliott Sclar, from Columbia University's Earth Institute, says that will open the door to discussions of future land-use made critical by climate change.
Scientists are experimenting with rebuilding oyster reefs off the coast of New York City. One writer suspects that if these structures had been in place, Hurricane Sandy's massive storm surge would have been greatly reduced.
China's efforts to grow its economy and its manufacturing base are meeting resistance as the country's middle class burgeons. In Ningbo, a plan to build a petrochemical plant was beaten back by protesters in the street who say these plants are affecting their health.
Getting a barrel of oil out of the ground takes energy. Years ago, you could get 100 barrels of oil out of the ground with just one barrel of oil spent. Now, it's more like 20 to one, or even five to one. That compares favorably with renewable energy sources -- but it all depends on how things are counted.
