GEOGRAPHY
1 Look at the picture and the tide of the article. What do you think the article is about? Listen, read and check
2 Read the text and decide if sentences 1 -6 are T (true), F (false) or NS (not stated).
1 Average global temperatures have Increased In the last century.
2 The 1990s wore one of the coldest decades on record.
3 Polar bears hunt for seals all year round.
4 There are now fewer polar bears In Hudson Bay than there were 10 years ago.
5 Polar bears usually raise more than two cubs.
6 Ice isn’t essential for polar bears to survive.
Global Warming
Global warming is a hot topic that shows little sign of cooling down. The Earth’s climate is changing, hut precisely how – or even if – we can stop the process is uncertain. Over the last century, average global temperatures have Increased by approximately one degree, while in Alaska. North-Western Canada and Eastern Russia it is believed average temperatures have increased by as much as three to four degrees. In the Northern Hemisphere, the spring thaw occurs nine days earlier and the winter freeze happens about ten days later than it did 150 years ago, and the last two decades have been the warmest ever recorded since the mid- 1800s.
Global warming has serious repercussions for life on the planet. One immediate result is that many animal species arc lighting for survival. One example is the polar bear population that lives in the Hudson Hay area of Northern Manitoba. The reduction in ice, as well as a shorter winter season, means that the bears have a reduced hunting period. For some bears, their yearly food intake has decreased by as much as ten kilograms. Some of them are not able to survive the summer fast because they have not stored enough energy to sustain themselves. They need the ice to cover the sea during the winter months so they can hunt for seals, their main source of food. However, the sea ice is melting and breaking up because of global warming. Glaciers and icebergs are receding anti disappearing at alarming rates. Studies suggest that the West Hudson Hay polar bear population has decreased by as much as 20 percent in just 10 years.
Warmer weather in the region also has a cataclysmic effect on female bears and their maternity dens. Many dens collapse in the spring, due to heavy rains, and trap the mothers and their cubs. In some instances, the increased temperatures melt the frozen ground where the dens are located, also causing them to collapse. Unless the mother and cubs are rescued, most of these animals die.
If we continue to do nothing to reduce the emission of greenhouse gases and continue to pollute our environment, ice conditions in the Hudson Bay area will not be able to sustain and support its population of polar bears, and we will have forced yet another species into extinction.
