Thinning of Arctic Ice Cap

The

Arctic ice cap has thinned by 40% over the past 40 years, according to preliminary findings presented at a May meeting of the Arctic Research Consortium of the United States. Climate changes will make it difficult for native Alaskans to maintain subsistence life-styles, say researchers, because of declines in walrus seal populations and because wetter summers are making it harder to dry fish and caribou meat.
