challenges... Global Warming Global warming is nothing new. We all know that burning fossil fuels, greenhouse gases and deforestation are 1) meaning/causing/putting/effecting world temperatures to rise. But 2) to/from/about/over the past 50 years, Antarctica's temperatures have increased by about 3°C, around 10 times more than the rest of the world! As a result, glaciers and sea ice are melting and ice shelves are breaking off into the sea, which is very bad news! If Antarctica's thick, polar ice sheet 3) eventually/lastly/lately/truly melts, not only will the world heat up generally, but global sea levels could rise by about 6 metres, flooding many coastal areas. This is extremely worrying, as almost every city with over 10 million people is 4) at/on/about/around the coast! Another problem is that melting ice forms clouds, which 5) directs/leads/follows/results to more snowfall. This can make life very difficult for some of the wildlife in Antarctica, such as penguins, whose eggs rot in the snow. Scientists are
