The giant arctic ice cap may be melting as a result of global warming, according to a new paper by an international team of researchers. An analysis using complex computer programs that mimic the climate system indicates only a 2% chance that arctic melting over the last 19 years is a result of natural climate changes, according to the paper appearing in today's edition of the journal Science.
