National Academies Report: "Farming Practices Should Evolve to Meet New Challenges, Expanding Needs"

HTTP://NATIONAL-ACADEMIES.ORG/morenews/20100629.html

"...To help achieve a sustainable agriculture system that looks beyond the end goal of providing more goods, the committee identified four goals that should be considered simultaneously:

--satisfy human food, fiber, and feed requirements, and contribute to biofuels needs .         

--enhance environmental quality and the resource base

--maintain the economic viability of agriculture

--improve the quality of life for farmers, farm workers, and society as a whole..."

"Stopping the Worst Environmental Disaster?: An Ethical and Scientific Comparison of the Gulf Oil Spill and Climate Change."

http://rockblogs.psu.edu/climate/2010/06/stopping-the-worst-environmental-disaster-an-ethical-and-scientific-comparison-of-the-gulf-oil-spill.html

Donald A. Brown: "...Climate change not only threatens more people, animals, and ecological systems around the world than the Gulf spill; it promises to be a problem that will continually wreck havoc for centuries while harming the world's poorest and most vulnerable people with drought, floods, killer storms, rising sea levels, and vector borne disease.

"BP may shut down the oil gusher in the Gulf by the end of the summer, yet the harms from human-induced climate change will likely plague the world for centuries. While the threat from the BP gusher to the wildlife in the Gulf is huge, the threat to people, animals, and ecological systems from climate change is much larger..."

NASA Earth Observatory: "As of June 27, 2010, the entire gulf-facing beachfront of several barrier islands in eastern Mississippi (offshore of Pascagoula) had received a designation of at least "lightly oiled" ... A few small stretches of Petit Bois Island had been labeled heavily or moderately oiled.

"This high-resolution image shows Petit Bois Island (top right) and the eastern end of Horn Island (top left) on June 26. In general, oil-covered waters are silvery and cleaner waters are blue-gray....

PNAS: Experts believe climate could reach tipping point (via @eurekalert)

"Expert judgments about transient climate response to alternative future trajectories of radiative forcing"

http://www.pnas.org/content/early/2010/06/24/0908906107

Authors: Kirsten Zickfeld, M. Morgan, Dave Frame, and David Keith

Study description from Eurekalert: "The odds may be better than 50-50 that human-induced global warming can push Earth’s climate past a tipping point within 200 years, if carbon dioxide emissions continue to increase, according to a survey of climate experts. 

"Researchers have recently begun defining tipping points as fundamental climate shifts that affect at least half the planet and persist for several decades. M. Granger Morgan and colleagues conducted face-to-face interviews with 14 prominent climate scientists who, according to the study, represented the range of mainstream opinion. 

"During the interviews, the experts were presented with low, medium, and high trajectories for CO2 increases —all within the latest IPCC projections—through the year 2200, and were asked to specify the probability that each of the scenarios would force the climate system past a tipping point. 

"The authors report that for the high trajectory, 13 of the 14 experts responded that the probability was greater than 50%, and 10 specified 75% or more. The potentially climate-altering CO2 scenario, though high, is still within the range of plausible scenarios offered by the IPCC, according to the authors."

Study assesses carbon sequestration leakage risks (via @eurekalert @naturenews)

Eurekalert: "Carbon sequestration: Boon or burden?" "...Large scale use of carbon sequestration could help to avoid extreme global warming that would otherwise occur in the near future unless fossil fuel emissions are reduced significantly. But it is not clear how effective different types of sequestration are in the long run, owing to leakage of stored CO2 back out to the atmosphere. Nor is it clear what would be the long-term consequences of such leakage for the Earth's environment...."

Shale Gas: Hydrofracking: "The Next Drilling Disaster?" (via @thenation)

http://www.thenation.com/article/next-drilling-disaster?page=full

"Hydrofracking is a hugely lucrative and rapidly expanding industry--the consulting firm PFC Energy recently reported that shale gas production accounts for about 10 percent of US natural gas production, up from 1 percent in 2000. It is bolstered not only by a powerful lobby but also by growing awareness of the threats posed by climate change and America's dependence on foreign oil. 

"In recent years, a broad coalition of energy analysts and government officials have embraced domestic natural gas as a promising "bridge fuel" that could help smooth the transition from more carbon-intensive fossil fuels like oil and coal to renewable energy sources like solar and wind. The catch, though, is that the natural gas industry shares the same history as other energy industries operating in the United States. 

"A string of recent disasters--including the TVA coal ash spill, the Massey coal mine explosion and the Deepwater Horizon oil spill--have demonstrated all too vividly that failure to regulate and oversee resource extraction can lead to catastrophe. Some fear that Dimock is the first natural gas casualty, an early warning of what could happen on a much larger scale if fracking spreads unchecked to other residential areas in the Marcellus region and across the country..."

Hard Times: When it paid to photograph the hard truths (via @latimes) #documentary #photojournalism

http://www.latimes.com/news/science/environment/la-ca-doc-photos-20100627,0,3090645.story

"The 10 photographers in 'Engaged Observers,' opening June 29 at the Getty Museum, are bound by a personal perspective and an endangered profession."

Leah Ollman: "The 10 photographers in "Engaged Observers," opening June 29 at the Getty Museum, are at once storytellers, witnesses, advocates for justice, investigative journalists, consciousness raisers, evidence gatherers and educators. They're also something of an endangered species, threatened by the destruction of their professional habitat...

"...The tenuous state of print journalism, with so many publications closing or contracting, suggests a rough road ahead for photographers (as with writers) needing time and support to address subjects with depth and complexity. The Internet offers myriad new avenues for exposure but no viable system to pay for such work to be produced. Also, viewing an extensive essay on screen is not the same as making one's way through the pages of a book or magazine.

Global Migration: A World Ever More on the Move (via @nytimesweek)

http://www.nytimes.com/2010/06/27/weekinreview/27deparle.html?ref=weekinreview

Jason DeParle: "Perhaps no force in modern life is as omnipresent yet overlooked as global migration, that vehicle of creative destruction that is reordering ever more of the world. Overlooked? A skeptic may well question the statement, given how often the topic makes news and how divisive the news can be. After all, Arizona's campaign against illegal immigrants, codified in an April law, set off high-decibel debates from Melbourne to Madrid. But migration also shapes the landscape beneath the seemingly unrelated events of the headlines. It is a story-behind-the-story, a complicating tide, in issues as diverse as school bond fights and efforts to isolate Iran. ..."

Seeking Answers on Gulf of Mexico Oil Spill as Questions Mount

http://www.nytimes.com/2010/06/26/us/26primerWEB.html

"Since the Deepwater Horizon oil rig exploded in the Gulf of Mexico in April, killing 11 and setting off the biggest maritime oil spill in the nation’s history, questions about the potential dimensions of the disaster have only multiplied from week to week. Readers have been asking whether the oil can be contained, how serious the damage will be and what they can do to help....a primer on the spill."
