Burst Pipeline Spills Crude Oil on California Coast
Posted by Environment News Service: None Given on May 21st, 2015
Environment News Service: Thousands of gallons of black smelly crude oil that spilled from a broken pipeline Tuesday in the California coastal county of Santa Barbara has fouled popular beaches and spread across nine miles of ocean.
Reported by a passerby early Tuesday afternoon, the spill occurred near Refugio State Park west of the city of Santa Barbara. Officials have closed the popular park and have also closed El Capitan State Beach over the upcoming Memorial Day weekend.
Officials said up to 105,000 gallons could...
Why Africa particularly vulnerable climate change
Posted by Conversation: Robert Scholes on May 21st, 2015
Conversation: When it comes to climate change Africa is in the eye of the storm. This is partly because of human factors - but the continent’s climate also makes it extremely vulnerable.
Africa is faced with a number of interlinked challenges. These include land degradation, poverty and climate change. These are referred to as “wicked problems” since they are complex and caused by a number of factors, many of which have global dimensions.
In the case of climate change, Africa is vulnerable because it is...
Mike Huckabee can’t make up his mind about ethanol
Posted by Grist: None Given on May 20th, 2015
Grist: On the campaign trail, GOP presidential hopeful Mike Huckabee has been a vocal supporter of the ethanol industry. The former Arkansas governor has repeatedly spoken out in defense of the Renewable Fuel Standard -- the federal policy that requires energy companies to blend billions of gallons of biofuels into the nation`s gasoline and diesel supply. That makes political sense in Iowa, where corn is big business. Ethanol made from corn constitutes the vast majority of domestic biofuel consumption....
Obama: Climate change poses “immediate risk” to national security
Posted by Grist: None Given on May 20th, 2015
Grist: President Barack Obama had a strong message for graduates of the Coast Guard Academy in Connecticut on Wednesday, and all the rest of us too: Global warming is a major security threat.
During a commencement address at the academy, he linked changes in the climate to volatility and violence in the Middle East, and warned that global warming to undermine military readiness. He said military forces must adapt and prepare for the kinds of changes we`re already starting to see, but "such preparation...

ScienceDaily: For the first time, scientists at the Senckenberg Research Center for Biodiversity and Climate and the Research Institute Senckenberg in Gelnhausen have modeled the effects of land use changes on the species diversity in rivers and streams. Their results show that the loss of biodiversity is caused to a significantly higher degree by changes in land use practices than by climate change. In consequence, conservation concepts for this valuable ecosystem and the organisms that live in flowing water...

ScienceDaily: Professor Edward Hanna and PhD student Richard Hall, from the University of Sheffield's Department of Geography, are part of a select group of international climate scientists investigating links between Arctic climate change and extreme weather in the northern mid-latitudes.
They have found that while it is too soon to know for certain whether the Arctic played a role in persistent cold events during the extreme wet UK winter of 2013/14 and recent USA East Coast winters, new studies are adding...
Second Largest Island in U.S. Goes 100% Renewable
Posted by EcoWatch: Laurie Guevara-?Stone, Rocky Mountain Institute on May 20th, 2015
EcoWatch: As most Alaskans can attest, energy in The Last Frontier is expensive. The average residential electricity rate of more than 18 cents per kWh is a full 50 percent higher than the national average, ranking among the highest in the country. That’s in part because outside the 50 hydro plants throughout the state, most of Alaska’s rural communities rely on imported diesel for their electricity. But the folks of Kodiak Island (pop. 15,000) in southern Alaska--powered almost 100 percent with renewable...
Air quality effects of natural gas extraction detected in PA’s Marcellus Shale region
Posted by Washington Post: Juliet Eilperin on May 20th, 2015
ScienceDaily: A team led by environmental engineers from Drexel University are the first independent researchers to take a closer look at the air quality effects of natural gas extraction in the Marcellus Shale region of Pennsylvania. The group used a mobile air quality monitoring vehicle to survey regional air quality and pollutant emissions at 13 sites including wells, drilling rigs, compressor stations and processing areas. Their work establishes baseline measurements for this relatively new area of extraction....

Bloomberg: Lester Brown has spent his career making shrewd projections about the food, water, and energy people need to survive, and pushing governments to respond. None of this math brings tears to his eyes except the time in 1965 he made some calculations and risked his career advising the president of the United States to save India from starving.
Brown's eyes misted over as the 81-year-old resource economist recalled the reaction of a U.S. agriculture attache in New Delhi to his discovery that famine...

Posted by Washington Post: Juliet Eilperin on May 20th, 2015
Christian Science Monitor: As global warming progresses, look for increasing expanses of majestic forests worldwide to become short and scrubby.
That is the implication of a new study that applies a well-established principle of fluid flow to the inner workings of vegetation.
The analysis doesn't attempt to specify timing or specific locations where such shifts in vegetation would occur. Instead, it uses the principle known as Darcy's law to explore the general types of vegetation most likely and least likely to survive...
