| National Geographic: Arctic Ocean sea ice is melting faster than even the most advanced climate change models predict, a new study concludes. The work, published today in the journal Geophysical Research Letters, used the models to retroactively predict sea-ice decline from 1953 to 2006. Scientists then compared the results to what has actually been recorded by Earth-based and satellite observations during that time frame. The team found that, on average, 18 climate models used in a 2007 ... |
