 For all its remoteness, Antarctica has become increasingly accessible in recent years. Weather permitting, flights land regularly at the South Pole, bringing construction crews and materials there. Dozens of research stations have been planted all round the coastline. Now, fleets of cruise ships are bringing over 12,000 people a year and the Antarctica is also becoming an increasingly popular venue for extreme sports.

 Antarctica is owned by no one, and 43 nations are joined in an agreement which allows it to be used only for science and tourism. Yet these activities are already so intensive that they may soon pose a threat to the environment It is also feared that the agreements may not withstand pressures to exploit the continent’s mineral resources including gold, platinum and oil. Of equal concern is the possibility 10 of shipping accidents due to the influx of ships into the Southern Ocean. which could lead to devastating oil spills.

Global warming could have an even more devastating effect. Average temperatures in the Antarctica have risen to 2.5°C in the last 50 years, and the Ice sheet is melting more rapidly than scientists anticipated. Large chunks of ice are now actually breaking off or ‘calving’ to create icebergs like those in the Arctic. disrupting penguins’ breeding grounds in the process. The huge Larsen B Ice Shelf-a 200 metre thick sheet of floating ice as big as Jamaica, recently broke up. shocking scientists, who had not thought it would happen so soon.

Scientists fear that if the West Antarctic Ice Sheet melts, it could raise sea levels by several metres with devastating results for the world’s coastlines.
