Climatologist Dr. Mark Serreze at the National Snow and Ice Data Center in Boulder, Colorado, has announced that the recent appearance of open water at the North Pole “is nothing to be necessarily alarmed about.” He continued, “we have no clear evidence at this point that this is related to global climate change.” He stated that open water at the North Pole is a commonplace occurrence, but the only earlier satellite data showing the phenomenon was from July of 2000, a month earlier than the event reported recently.
Indications that the ice cap is melting remain overwhelming, despite this apparent attempt by one scientist to minimize the problem. Dr. Drew Rothrock at the Applied Physics Laboratory of the University of Washington in Seattle has compared measurements of ice thickness between 1958 and 1976 with data from 1993 and 1997. This indicates that the ice cap’s thickness had been cut in half over this period, from an average of 10.2 feet to an average of 5.9 feet.
In addition, a study reported last summer in the Dutch journal Climate Change indicates that average temperatures in parts of Alaska and northern Eurasia had risen 11 degrees during winter months over the past 30 years.
No scientist involved in studies of ocean salinity or currents has recently commented on the danger that rapid arctic melt poses in these crucial areas.
