"The 2007 Arctic summer sea ice has reached the lowest extent of perennial ice cover on record - nearly 25% less than the previous low set in 2005. The area of the perennial ice has been steadily decreasing since the satellite record began in 1979, at a rate of about 10% per decade. But the 2007 minimum, reached on September 14, is far below the previous record made in 2005 and is about 38% lower than the climatological average." Original Nasa Webpage

It's a riotously geeky a cappella ode to Noctilucent Clouds...
Ok, here's another naughty extra. This was one of the recommended videos
after watching "Noctilucent Clouds". Go figure. I'm just speechless.
