Good morning. I will be talking to you about the Arctic ice melting that took place just last year. The Arctic's sea ice melted at a record pace in 2012, the ninth-hottest year on record. This compounded concerns about climate change, which is leading to more extreme weather. During the August to September melting season, the Arctic's sea ice cover was just 3.4 million square kilometers. This was 18% less than the previous record low, which was set in 2007. The World Meteorological Organisation Secretary General, Michael Jarraud, says it is a sign of climage change. The year of 2012 saw many other extreme weather as well, such as droughts and tropical cyclones.
Earth's climate changes naturally and these natural variability in weather patterns can result in extreme climate, but extreme climate events are increasingly shaped by climate change.
