The relative swiftness of this ship's drift, compared with a journey taken a century ago, stands as another sign of the melting Arctic ice cap, which in turn represents the most visible sign of the threat of global warming.

Question: If the Arctic ice is melting so quickly, why is the red line for April 20, 2009 HIGHER than all of the other lines?

Bonus question: Why is the red line here also ABOVE zero?
