The removal of hundred year old dams along the Elwha river in Washington State have freed up salmon runs, but they have also clogged up a water treatment plant with sediment. Still as Ashley Ahearn of the public radio collaborative EarthFix reports, that sediment is creating a great habitat for fish.

A new report from the Center for Climate and Energy Solutions, C2ES, pegs US carbon dioxide emissions at levels not seen since the mid 1990’s. Natural gas replacing coal for power generation has helped to lower emission rates, but methane leaks from wells and pipelines adds a powerful greenhouse gas to the atmosphere. C2ES president Eileen Claussen explains the methane leaks to host Steve Curwood.

The first ships sailed down the Panama Canal in 1914. Now, nearly one hundred years later, Nicaragua has an agreement with a Chinese company to build a canal of its own to link the Pacific and Atlantic. Journalist Tim Rogers and host Steve Curwood discuss the potential environmental impacts of this 40 billion project.

Researchers at the University of Texas have developed an “invisibility cloak” using a meta-screen of ultra-thin copper wire. Naomi Arenberg reports on the implications of this disappearing act.

The world’s two largest global warming gas emitters, the United States and China, have forged an agreement to work together to cut their use of climate-disrupting hydrofluorocarbons. Jennifer Morgan, director of climate and energy programs at the World Resources Institute, joins host Steve Curwood to discuss the significance of the deal.

The American Bittern’s camouflaged plumage makes it nearly impossible to see when standing still. But writer Mark Seth Lender was lucky enough to find one strutting its stuff on a pond in northern Maine.

A new report suggests that by the year 2050 as much as half of South Africa’s wine growing region will no longer be able to grow grapes as a result of climate change. Living on Earth host Steve Curwood visited Backsberg Estate Cellars, South Africa’s first carbon neutral vineyard to see how it is already adapting and implementing creative solutions to reduce its contribution to greenhouse gas emissions.
