Since 1979, scientists have observed that, in the month of September, the amount of sea ice on the surface area of the ocean has declined significantly

A new low for global warming: Sea ice retreats to furthest point on record

Sailing beyond the Arctic Circle is one of the few fast-growing sectors of the cruise industry. More ships are based at UK ports for the summer than ever, with many venturing to Norway, the Faroe Islands, Iceland and beyond. A voyage to the far north is immensely appealing. In one sense an Arctic adventure is the ultimate day trip, because the summer sun will not fall beneath the horizon all summer. And a thousand miles beyond the tree line, tourists can confront some of the world's rawest edges from the comfort of a cruise-ship cocoon. Mountains that no human has ever climbed soar from the ocean. Thick veins of snow trickle from the peaks and fuel the glaciers that gouge through the rock in geology's perpetual power struggle.
