Glaciers a Mixed Bag
Glaciers around the world thinned by an average of 29 inches in 2007, which indicates to Swiss scientists that they are melting twice as fast as they were in the 1980s and 1990s. But, wait. A few paragraphs down, itâ€™s explained that Alpine glaciers retreated while coastal glaciers in Norway actually gained thickness in 2007. Also, the rate of glacial decline was less in 2007 than in 2006. So with the planet not having gotten any warmer since the late 1990s, and some glaciers actually growing, is this really any evidence of anything at all?
