英语听力：自然百科 冰冻星球 前往地球尽头—8

 A colossal¹ iceberg² is born. This single block of ice, many hundreds of meters across would dwarf³ the biggest of mankind buildings.

 

Every year, tens of thousands of icebergs⁴ are spawned⁵ by Greenland's glaciers⁶, and their number is steadily⁷ increasing as the climate continues to warm.

 

The breakup of the bergs fills the base of the Arctic with exquisite⁸ ice sculptures. It also releases great volumes of cold fresh water into the sea. Greenland's melt water influences the course of the ocean currents, which in turn has an effect on the weather around the world.

 

The Arctic is closer to home than many of us realize. It includes the northern most parts of the three continents on which most of us live, Europe, Asia and North America.

 

The first bare land we reach on our journey south is a bleak⁹ treeless wilderness¹⁰ known as Tundra¹¹. Each spring, animals travel up from the south to be ready for the rich grazing that will be unveiled by the spring melt. For the caribou¹², the timing¹³ is critical; arrive earlier and a winter storm could kill you; delay too long and you may fail to lay down the fat needed to survive a polar winter.
