Edge of The Ice
A record low ice area was recorded on August 9. The remark in the news that caught my attention though was the following: last week the Russians planted a flag on the seabed at the North Pole. The Canadian prime minister then noted that, "international interest in the region [was] increasing." Great! So we're all screwed folks, but don't worry, there's plenty more oil under the melting ice!
Of course the issue is not about longer summers or more oil: it is about water. If the arctic ice melts, the land locked ice probably will also. A one millimetre rise in sea levels probably won't radically alter the real estate value of Joe's waterfront mansion, but that's already a lot of fresh water. And if the Greenland ice sheet melts, Joe's house will be way under water. There's water in the oceans, lakes, rivers, atmosphere and ice: take some from somewhere and it goes somewhere else. Pretty simple. Then again, as one cheerful commenter pointed out, there might be a worldwide famine in 3 years time when the farmers all plant the wrong crops due to the unpredictability of the weather for the season ahead (or the fact that the farm turned into a desert) so we might not need so much water (because a lot of us will be dead).
