  Jason 2 to map the height of the oceans now and over time. Beach erosion, fisheries, oil companies and other various industries are very interested in these data. Power plants use sea water for cooling, so care about its temperature.

• Huge sea level rises are coming – unless we act now - environment - 25 July 2007 - New Scientist
  James Hansen heads NASA's Goddard Institute for Space Studies in New York. A physicist and astronomer by training, he began his career studying the clouds on Venus. Since the late 1970s he has been studying and modelling the human impact on Earth's climate, and has published more than 100 papers. He entered the public spotlight in the 1980s with his outspoken testimony to congressional committees on climate change. Last year he made headlines when he spoke out against attempts by the US administration to gag climate scientists.

• NASA Flies to Greenland to Extend Polar Science
  Imagine a piece of ice 1,000 miles long, 400 miles wide, and 2 miles thick in the center. That's the Greenland ice sheet. But that island-sized piece of ice is melting, so NASA researchers are flying to the Arctic this week to learn more about the nature of those changes.

• New NASA Satellite Survey Reveals Dramatic Arctic Sea Ice Thinning - NASA Jet Propulsion Laboratory
  Arctic sea ice thinned dramatically between the winters of 2004 and 2008, with thin seasonal ice replacing thick older ice as the dominant type for the first time on record. The new results, based on data from a NASA Earth-orbiting spacecraft, provide further evidence for the rapid, ongoing transformation of the Arctic's ice cover.

• Scientific Value of Arctic Sea Ice Imagery Derived Products
  During the 1990s, a government program brought together environmental scientists and members of the intelligence community to consider how classified assets and data could be applied to further the understanding of environmental change. As part of the Medea program, collection of overhead classified imagery of sea ice at four sites around the Arctic basin was initiated in 1999, and two additional sites were added in 2005. Collection of images during the summer months at these six locations has continued until the present day. Several hundred unclassified images with a nominal resolution of 1 meter have been derived from the classified images collected at the 6 Arctic sites. To assist in the process of making the unclassified derived imagery more widely ...
