Spy photos of Arctic ice

A number of sources are reporting that the Obama administration has made public spy photos that show the effects of climate change in the Arctic. The photos have a one metre resolution, and were provided through a program called Medea which allows scientists to request intelligence images of environmentally sensitive areas.

With luck, the photos will allow climate models to be further refined: for instance, by better incorporating the positive feedback associated with changed albedo when white ice melts and is replaced by darker water. Other scientific information that could be derived from the photos includes: “the relationship of snow to ice-surface topography, the initiation and development of meltwater ponds in summer, and the relationship of stress and strain and how they are reflected in the pattern of cracks and other features in the ice.” Thorsten Markus – at NASA’s Goddard Space Flight Centre – has said that the key value of the new images lies in their high resolution, compared to those that were previously available.

In the spring of 2005, I graduated from the University of British Columbia with a degree in International Relations and a general focus in the area of environmental politics. In the fall of 2005, I began reading for an M.Phil in IR at Wadham College, Oxford. Outside school, I am very interested in photography, writing, and the outdoors. I am writing this blog to keep in touch with friends and family around the world, provide a more personal view of graduate student life in Oxford, and pass on some lessons I've learned here.
