Scale is hard to judge in the Arctic because of its ubiquitous icy-white backdrops. Yet much the biggest part of the iceberg--perhaps nine times the size of the visible part--is submerged and invisible. As it drags along the bottom of the Jakobshavn Fjord, this mass of ice could cause earth tremors. Were it to flip over, pressed by sea ice from behind, it might cause a tsunami. The Arctic will retain its power to amaze for a long time. Yet it is now changing beyond the usual regional and annual variations in sea-ice formation, glacier melt and so forth. The Arctic is clearly melting. Its floating ice cap is shrinking and thinning and its glaciers are retreating. By the end of this century, maybe much sooner, there will be frequent Arctic summers with almost no sea ice at all. Why does this matter?
