The sea ice minimum in the 1970s was 5.5 million square kilometers. Then in the 1980s it was 5.0 million square kilometers. Then in the 1990s it reached 4.5 million square kilometers. Then by 2005 we touched 4.01 million square kilometers as the prior record.
Then comes 2007. Oh my, does 2007 come roaring by! On August 9, 2007 we set a new record low of 3.98 million square kilometers! But just 19 days later we set a new minimum of 2.99 million square kilometers.
Did you get that yet? We lost one million square kilometers of sea ice in 19 days.

The more ice free sea there is , the more heat is absorbed - which leads to more ice melting and more ice free sea, and so on. It's a "positive feedback loop", the melting is not linear.
I don't know if global warming is all our fault but I think this is significant news.
