Hundreds of images derived from classified data that could be used to better understand rapid loss and transformation of Arctic sea ice should be immediately released and disseminated to the scientific research community, says a new report from the National Research Council. The committee that wrote the report emphasized that these Arctic images show detailed melting and freezing processes and also provide information at scales, locations, and time periods that are important for studying effects of climate change on sea ice and habitat -- data that are not available elsewhere.
"To prepare for a possibly ice-free Arctic and its subsequent effects on the environment, economy, and national security, it is critical to have accurate projections of changes over the next several decades," said committee chair Stephanie Pfirman, professor and chair of the department of environmental science at Barnard College, New York City. "Forecasts of regional sea-ice conditions can help officials plan for and adapt to the impact of climate change and minimize environmental risks."
Projections of future Arctic ice cover are hampered by poor understanding of sea-ice physical processes because few observations exist at appropriate times and scales. Readily available satellite images are too coarse to capture the details, the report says. In addition, collecting ground-based data by maintaining manned-drifting stations is challenging due to rapidly changing environmental conditions and the weak platform of ice, and collecting data from observational aircraft flights is difficult and expensive.
"At a time when there is concern that Earth observation systems are decreasing and aging, releasing these images would be a step toward continuing the flow of critical information to the scientific community," said Ralph J. Cicerone, president of the National Academy of Sciences. "We hope that these images are the first of many that could help scientists learn how the changing climate could impact the environment and our society."

You can also buy the sat maps online. Yes I do know and I think this story is just trying to start something, with say Bush lovers. I dont know what your point is. And I see that not alot of people seem to be posting. So I think its a non-story. If you cant find the photos online, your not looking. CIA my ass, NASA will give them the photos everytime, just ask !

Im a spy, and use NASA, NOAA, and Google earth and Google maps that show the same thing. You dont need the CIA sats to see this. Im am also fan of the BS that you set a write all day. Al Gore will never love you like I do.:p
