Blocks Of Ice

Recently i linked to a Catalyst report - which mentioned the increase in Antarctic ice melt from 75 to 150 billion tonnes per year. Sometimes it's hard to imagine what that much ice looks like. Fortunately, John Cook's visualisation of the Greenland ice melt helps us get the picture.

With the Empire State Building for scale, this is 1 billion tonnes of ice.
