Melting Ice

I was reading my feeds and came across this photo taken on a flight to the States. As the author denoted, the flight was passing over the North Pole:
Though it might be exciting to fly over the North Pole, it is worrying to see the ice as 'floating blocks'. It wouldn't be long until all ice in the poles are gone. Help save the planet, turn your air conditioner to 25.5^oC and don't even turn it on if you don't need it!
