How Long Can Oceans Continue
To Absorb Earth’s Excess Heat?

by cheryl katz
The main reason soaring greenhouse gas emissions have not caused air temperatures to rise more rapidly is that oceans have soaked up much of the heat. But new evidence suggests the oceans’ heat-buffering ability may be weakening.

Two Towns Face the Fallout

For two towns in northern India, melting glaciers have had very different impacts — one town has benefited from flowing streams and bountiful harvests; but the other has seen its water supplies dry up and now is being forced to relocate.

Stay Off-Limits to Oil Drilling

It’s not just the potential for a catastrophic spill that makes President Obama’s proposal to open Atlantic Ocean waters to oil exploration such a bad idea. What’s worse is the cumulative impact on coastal ecosystems that an active oil industry would bring.

Hawaii’s Solar Power Surge?

by erica gies
Blessed with lots of sun and keen to cut its reliance on imported oil, Hawaii has moved to the forefront of residential solar installations in the U.S. But financial and technical hurdles are slowing the state’s drive to generate 40 percent of its electricity from renewable energy by 2030.

Interview: Why This Tea Partyer
Is Seeing Green on Solar Energy

Debbie Dooley’s conservative credentials are impeccable. She was one of the founding members of the Tea Party movement and

Debbie Dooley
continues to sit on the board of the Tea Party Patriots. But on the issue of solar power, Dooley breaks the mold. To the consternation of some of her fellow conservatives, she has teamed up with the Sierra Club and other environmental organizations, first in Georgia and now in Florida, to form the Green Tea Coalition. The group is working to get an initiative on the Florida ballot that would allow individuals and businesses to sell power directly to consumers. In an interview with e360, Dooley explains why she supports solar energy campaigns and why she’s willing to go up against conservative organizations when it comes to this issue.

tax policies that promote renewable sources of energy and energy efficiency, according to a new report from the Yale Project on Climate Change Communication. Among Catholics, 69 percent think global warming is happening, which is a higher percentage than Americans overall (63 percent). A majority of non-evangelical Protestants — 62 percent — also think global warming is occurring, as do 51 percent of evangelicals. The survey also found that majorities of Catholics, Protestants, and evangelicals say it is important to them personally to care for future generations, the natural environment, and the world’s poor. Of the three groups, evangelical Christians were the most likely to say that God expects people to be responsible stewards of nature.

 

Natural Filters: Mussels Deployed
To Clean Up Polluted Waterways

When rivers and streams become polluted, one of the first casualties is often freshwater mussels, which effectively filter

out pollutants but can also be overcome by them. As a result, freshwater mussel populations worldwide have steadily dwindled. Now, however, conservationists and scientists in the U.S. and Europe are working to re-establish declining or endangered freshwater mussel populations so these mollusks can use their natural filtration abilities to clean up excess nutrients and runoff in waterways. One such program has been established on the U.S.’s Delaware River, where environmentalists and biologists are re-seeding mussel populations in the more polluted sections of the river and in tributary streams.

31 Mar 2015: Major Wildlife Impacts
Still Felt 5 Years After Gulf Oil Spill

Nearly five years after the Deepwater Horizon oil spill, dolphins in the Gulf of Mexico continue to die at unprecedented rates, endangered Kemp’s ridley sea turtles are experiencing diminished nesting success, and many species of fish are suffering from abnormal development among some juveniles after exposure to oil. Those are the conclusions of a new study from the National Wildlife Federation, released three weeks before the fifth anniversary of the Deepwater Horizon spill, which began on April 20, 2010. The study also said that populations of brown pelicans and laughing gulls have declined by 12 and 32 percent respectively, and that oil and dispersant compounds have been found in the eggs of white pelicans nesting in Minnesota, Iowa, and Illinois. The National Wildlife Federation said that the oil giant, BP, must be held fully accountable for the environmental damage and that fines and penalties should be used to restore habitats in the Gulf. Meanwhile, in advance of the spill’s fifth anniversary, BP is stepping up its public relations efforts to assure consumers that life is returning to normal in the Gulf.

 

Back from the Brink: Success Stories
Of the U.S. Endangered Species Act


A small minnow known as the Oregon chub recently became the 29th species to recover after being listed as endangered under the U.S. Endangered Species Act and the first fish to ever join those ranks. The Endangered Species Act, signed into law in 1973, is widely considered one of the most important pieces of U.S. environmental legislation ever enacted. This e360 photo gallery highlights the 21 species native to the United States, including the bald eagle (above), that have made recoveries strong enough to be removed from the endangered list.

30 Mar 2015: Warming Winters Not Main
Cause of Pine Beetle Outbreaks, Study Says

Milder winters can't be blamed for the full extent of recent mountain pine beetle outbreaks in the western United States, according
pine forest

Pine forest affected by mountain pine beetles
to a new study by Dartmouth and U.S. Forest Service researchers. Winters have been warming across the western U.S. states for decades, as overall the coldest winter night has warmed by 4 degrees C since 1960. But that warming trend could only be the primary driver of increasing pine beetle outbreaks in regions where winter temperatures have historically killed most of the beetles, such as in the Middle Rockies, eastern Oregon, and northern Colorado, the study says. Warming is unlikely to have played a major role in other regions since winters were rarely cold enough to kill the beetles, according to the study published in the journal Landscape Ecology. Other factors — including changes in the pine beetles' seasonal development patterns and forestry practices that have influenced pine density and age — were likely more important, the authors say.
