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.

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.

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.
