“Almost half of the processes that are crucial to maintaining the stability of the planet have become dangerously compromised by human activity. That is the view of an international team of 18 researchers who provide new evidence of significant changes in four of the nine systems which regulate the resilience of the Earth.”
Nine planetary boundaries (the crucial processes)
Change in biosphere integrity (biodiversity loss and species extinction)
Stratospheric ozone depletion
Biogeochemical flows (phosphorus and nitrogen cycles)
Land-system change (for example deforestation)
Atmospheric aerosol loading (microscopic particles in the atmosphere that affect climate and living organisms)

Images of Change
Human activities, a changing climate and natural disasters are rapidly altering the face of our planet. Now, with NASA’s Images of Change iPad application, users can get an interactive before-and-after view of these changes.
The NASA App showcases a huge collection of the latest NASA content, including images, videos on-demand, NASA Television, mission information, news & feature stories, latest tweets, ISS sighting opportunities, satellite tracking, Third Rock Radio and much more.
“It’s an online system that provides an easy way to display maps of climate data, such as ocean temperature and salinity, over portions of the globe. For example, it can allow you to view how the temperature in the North Atlantic would change in the 21st century as compared with the 20th century.”

NAS, Royal Society Release Publication on Climate Change
“The U.S. National Academy of Sciences and the Royal Society, the national science academy of the U.K., released a new joint publication that explains the clear evidence that humans are causing the climate to change, and that addresses a variety of other key questions commonly asked about climate change science. “

“Warming Up to End Times: What the coming apocalypse means for libraries”
“There is no longer any point in debating the reality of global warming (or, if you prefer to be politically correct, climate change). The handwriting is on the wall: 2012 was the hottest year on record and the polar ice caps are melting at an alarmingly fast rate. Then there’s the new research report from the University of Cambridge, which says that the thawing of the Arctic permafrost layer could trigger the release of billions of tons of methane into the atmosphere, accelerating the dire consequences of climate change.”
“Now here is one big website for things so small! The educational website for the Society for General Microbiology, Microbiology Online is packed full of information about microorganisms. Combining animations and actual images of the microbes, the website offers students the opportunity to explore pages such as introducing microbes, microbes and the human body, microbes and food, and microbes and climate change. For teachers, the site provides information on such topics as microbes and basic principles, preparation of media and cultures, activities, and safety information. There are a number of free downloadable resources available to teachers, as well. Beyond the teacher and student pages, Microbiology Online also includes links to the latest news and podcasts/videos. The site is well organized and contains a lot of material to excite both students and teachers of the subject.”

This year we have a unique opportunity to share our knowledge of Earth’s biological diversity and encourage contributions to its conservation. The United Nations has declared 2010 the International Year of Biodiversity. Scientists and conservation practitioners from around the world have been working with their local and national governments to educate the public on species, ecosystems, and ecological processes. Our goal is to ensure significant advances in conservation policy that protect resources fundamental to human well-being are met in 2010.
To celebrate this year, Conservation Biology has created 3 FREE Virtual Issues. Read them here:
Compliments of Wiley – Blackwell publishers
Connectivity and Corridors Articles address phenomena and actions that affect movement of genes, organisms (including humans), and ecological processes. Articles also emphasize the influence of social and economic context on maintenance of connectivity.
Climate Change Articles highlight research in all conservation sciences – social, biological, and physical – that may reduce uncertainty about the potential effects of alternative management and investment decisions on diverse conservation targets.
Conservation Social Science Articles emphasize the necessity to change human behavior in order to achieve the vast majority of conservation objectives. Diverse societal structures and processes are relevant to conservation of Earth’s biological diversity.
"Ecological Society of America offers search facility in database of experts – 05 Apr 2010
The Ecological Society of America (ESA) has unveiled its updated resource for policymakers and members of the media. The Rapid Response Team (RRT) database, an ESA resource for several years, has now been made fully searchable. Users can find ecological scientists who specialise in a variety of fields, including climate change, invasive species, urban ecology, conservation and biofuels, or can locate an RRT member by name, affiliation or keyword.
Members of the RRT seek to provide on-call ecological expertise in a variety of ways, such as serving as panelists in briefings for congressional staff; providing expert testimony to Congress; analysing the likely ecological consequences of proposed changes to environmental regulations; and providing scientific feedback for news stories.
ESA claims to be the world’s largest professional organisation of ecologists, representing 10,000 scientists in the US and around the globe. Since its founding in 1915, ESA has sought to promote the responsible application of ecological principles to the solution of environmental problems through its reports, journals, research and expert testimony to Congress. The Society publishes four journals and convenes an annual scientific conference."
