Arctic Sea Ice Shrinks to Record Low (29th August, 2012)Scientists have announced that the layer of ice covering the Arctic Ocean has shrunk to an all-time low record. What's more, they say the ice could disappear altogether in future summers. The area of ice recorded on August 26 covered just over four million square kilometres, which is 70,000 square kilometres less than the previous low in 2007. Experts said that record was a one-off and would not be repeated. However, conditions have changed quickly. The USA's National Snow and Ice Data Center (NSIDC) said: "The ice cover is now just so thin and weak in the springtime that large parts of it can't survive the melt season…It's almost like parts of the Arctic have become a giant slushee at this time of year." Sea ice in the Arctic Ocean grows in winter and partly melts in summer. The amount of sea ice melting in the summer has greatly increased in the past few decades. Environmentalists attribute this to global warming. The NSIDC said the six lowest periods of sea-ice cover have now occurred in the last six years. It said more melting means there is less ice to reflect the sun's heat, which means the ocean gets warmer. This year's ice cover was fairly consistent with 2007 levels until July, after which it started disappearing at a faster rate. Meteorologists say a strong storm in early August could have broken up the thinner, weaker ice, making it melt faster. WARM-UPS1. SEA ICE: Walk around the class and talk to other students about sea ice. Change partners often. Share your findings with your first partner. 2. CHAT: In pairs / groups, decide which of these topics or words from the article are most interesting and which are most boring.
