The latest Arctic sea ice update from the National Snow and Ice Data Center (NSIDC) reports that the rate of melting has accelerated in the first 10 days of August. As a result, "Amundsen's historic Northwest Passage is opening up." Although the extent of melting so far is less than last year's record, it is still way ahead of the long term average.
