Sea ice in the Arctic Ocean is likely to shrink to a record small size sometime next week, and then keep on melting, according to scientist at the US National Snow and Ice Data Center. This summer has also seen unusual melting of the ice sheet covering Greenland, with NASA images showing that for a few days in July, 97 percent of the northern island's surface was thawing. The same month also saw an iceberg twice the size of Manhattan break free from Greenland's Petermann Glacier. The amount of sea ice in the Arctic is important because this region is a potent global weather-maker, sometimes characterised as the world's air conditioner. This year, the loss of sea ice in the Arctic has suggested a possible opening of the Northwest Passage north of Canada and Alaska and the Northern Sea Route by Europe and Siberia. As parts of the Arctic melted, 2012 also set records for heat and drought in much of the Northern Hemisphere temperate zone, especially the continental United States.
