>>> there's a new report out tonight on the level of ice in the arctic as monitored by the folks at the national snow and ice data center . they say it's at a record low now since the time when satellites started tracking it in 1979 . it is an ominous benchmark for the planet. the melting ice they say will not have a direct effect on sea levels , though they have been a concern. they found the only positive effect worth highlighting here is, the freeing up of shipping lanes.
