As the Arctic warms, the volume of ice in the region gradually declines, making it less likely ice will survive more than one year and thus exposing more open water at the end of each melt season. The downward trend and the increasing difference between seasons are in keeping with predictions of the effects of global warming. Satellite measurements of Arctic sea ice extent reveal a rapid decline over the past 30 years, particularly at the end of each year's annual melt season. We know the Northwest Passage had been open before." ( Matt Rogers)Īrctic sea ice has aptly been termed a "canary in the global warming coal mine," a sensitive indicator of climate change because of its importance as a diagnostic of global warming, climate change skeptics struggle to explain the decline of Arctic sea ice as a natural phenomenon. What you were not told was that the data that triggered this record is only available back to the late 1970s. At that point, we were told melting was occurring faster than expected. "In 2007, the Northern Hemisphere reached a record low in ice coverage and the Northwest Passage was opened.
