Arctic Ozone Loss 'Unprecedented,' Scientists Say

Unusual winter weather in the atmosphere high above the Earth's surface caused an "unprecedented" loss of protective ozone over the Arctic this year, scientists say.

The ozone layer in the stratosphere, located about 15 to 35 kilometres above the Earth's surface, protects the Earth from the sun's ultraviolet rays and harmful effects such as skin cancer. While an ozone hole has formed in the stratosphere over the Antarctic each spring since the mid 1980s, a paper published in Nature on Sunday marks the first time scientists have reported a comparable loss over the Arctic.

IT and Information Sharing Environments for Community Health Resilience

Information Technology (IT) and Information Sharing Environments (ISEs) are crucial to the evolution of community health resilience.  Most people working to improve community health resilience do not understand the nuances of Information Sharing Environments, and how the rapid shifts in IT, mobile devices, social media, cloud computing, peer to peer parallel processing, smart grids, and the linking of millions of people, mobile devices, computers, and sensors are creating a societal mind, which is transforming community health resilience and the health and human security of Americans.

If you have thoughts on these topics, please comment within this collaboratory thread.

The Power of the 21st Century Librarian

Michael D. McDonald, Dr.P.H.

It can be argued that libraries have their origins in the swarm behavior of individuals and groups acquiring and sharing cultural artifacts (e.g, pictographs, books) as the fundamental repositories of knowledge within a community and the broader society.  Librarians have played a key role in the founding and differentiation of  America at its origins.  Thomas Jefferson and Benjamin Franklin, for example, played key roles in deepening and broadening the tradition of knowledge sharing within the early United States.

Social Innovation in Venice California

Venice, California has long been a center of innovation within Los Angeles.  Its boardwalk is a spectacle of creativity and entrepreneurship in an open community setting, where the LA megalopolis meets the beach and the Pacific Ocean.  This combination attracts millions of visitors a year in a very small area.

As a result, Venice -- in addition to its opportunities, also struggles with significant and growing challenges with homelessness, drugs, and crowd control, amongst the other problems that all communities face in an economic downturn within a time of energy descent. 

The result?  Both the opportunities and the problems now require creative energy from the Venice community itself to shape what Venice wants to be in the early 21st century. 

Please place your comments on how Venice community members might think about shaping their community to enhance it during the challenging years ahead.

AP: BP Oil Not Degrading on Gulf Floor, Study Says

BIRMINGHAM, Ala. (AP) — Tar balls washed onto Gulf of Mexico beaches by Tropical Storm Lee earlier this month show that oil left over from last year's BP spill isn't breaking down as quickly as some scientists thought it would, university researchers said Tuesday.

Auburn University experts who studied tar samples at the request of coastal leaders said the latest wave of gooey orbs and chunks appeared relatively fresh, smelled strongly and were hardly changed chemically from the weathered oil that collected on Gulf beaches during the spill.

The study concluded that mats of oil — not weathered tar, which is harder and contains fewer hydrocarbons — are still submerged on the seabed and could pose a long-term risk to coastal ecosystems.

Controversial Study Shows Higher Cancer Risk in 9/11 Firefighters

(CBS) The 9/11 terrorist attacks in New York City killed almost 3,000 people, but what about New Yorkers who were in the area at the time but survived? New studies show they face heightened risk for asthma, post-traumatic stress disorder, and cancer - but not all health experts agree the attacks are to blame for survivors' health problems.

For one study - published in the September 1 issue of The Lancet - Mount Sinai researchers evaluated more than 27,000 police officers, firefighters, construction workers, and office workers who were in or around ground zero over the nine years following 9/11. The researchers found more than one in five responders had multiple physical or mental health illnesses.

The Economics of Rapidly Emerging Cities

As the human populations of our small planet exceeds 7 billion on its way potentially to 9 million or 10 billion by the mid-21st Century, migrations of millions are becoming common place -- some out of desperation, others out of seeking opportunity and a better life.  According to a large percentage of climatologists and other scientists that are studying global change, the social ecologies of many large cities will become non-viable for their human populations and many other species due to climate change, the drying up of water supplies, the lose of food sources, natural disasters, wars, and other factors.  In other cases, new cities of opportunity or attractive culture will draws those seeking a better life and way of being.  

Tens of millions, and perhaps hundreds of millions will be forced to leave their homes in search of more viable communities.  Millions more will create new communities with intentionality, exploring new economic, social, and political models that improve health, human security, resilience and sustainability for the new citizens.  In some cases, simple shared principles will shape new, fast growing economies, and, in other cases, rules and conditions will be imposed on inhabitants of new communities and cities.
