Приведем выдержку из задания из учебника Баранова, Дули, Копылова 7 класс, Просвещение: 3e Climate change
Energy from sun
Heat
Heat radiated from land
Heat trapped by CO2 in the atmosphere
Heat radiated off the sea
Burning of fossil fuels (coal, oil, etc) produces carbon dioxide.
power plant & car exhausts produce greenhouse gases like carbon dioxide (CO2)
Reading
1 Read the definition and look at the diagram. What causes high temperatures?
global warming (n) the increase of the average temperature on Earth
2 Look at the photographs in the text. How саn global warming affect life on our planet? What can we do?
Listen and read to find out.
3 Read again and say if the sentences are T (true), F (false) or NS (not stated).
1 Most of the world’s mountain glaciers will melt in the next 100 years.
2 It might not be possible to go on holiday to the Maldives in 2100.
3 Ice in Greenland is melting more slowly than five years ago.
4 Polar bears come from Greenland.
5 In a hundred years, polar bears may be extinct.
6 Warmer seas cause more extreme weather.
Global Warning!
The Earth is heating up and most scientists believe that it’s all our fault. When we burn fossil fuels, greenhouse gases such as carbon dioxide increase and surround the earth like a thick blanket. This traps heat and temperatures rise. Scientists say that in the next 100 years, average temperatures will rise by about 3°C. This doesn’t sound like a lot, but it means BIG trouble! Ice is already melting, sea levels are rising and the climate is changing. How exactly is all this changing our work), and what will happen if we don’t act in time?
Cities under the sea
According to recent climate reports, melting Ice from the polar ice caps and mountain glaciers could cause sea levels to rise by about 1 metre by 2100. If this happens, whole countries such as the Maldives will vanish and millions in low-lying areas like parts of Bangladesh will lose their homes. Already, two small Pacific islands have disappeared under the waves. Coastal cities including Shanghai, Bangkok, New York and London will also be under threat
In Greenland, ice is melting three times faster than just a few years ago. If the ice sheets of Greenland and Antarctica ever melt completely, sea levels will rise about 60 m. That’s enough to cover almost every major city on Earth!

Wildlife in great danger
Global warming is a serious threat to wildlife. In particular, Arctic polar bears are in great danger. The ice that they hunt from is melting very fast, so they have to swim further and further to find food. Many starve or drown. By 2100, summer ice may disappear completely in the Arctic, and polar bears probably won’t survive. Changing weather patterns and rising sea levels threaten thousands of other species too. Some people believe that 30-40% of the world’s species could become extinct because of climate change.
Wild wild weather!
Heavy rain and snow, storms, heatwaves, droughts, more powerful hurricanes and tornadoes… these all happen a lot more frequently these days and more and more climatologists now believe this is because of global warming. When sea temperatures rise, there are changes in the atmosphere. If you live in a chilly place, you might think global warming sounds great. But climate change doesn’t just mean hotter temperatures. It means more and more extreme and unpredictable weather!
So… what on earth can we do?
Reduce your carbon footprint*. Cycle, walk, or take a bus instead of travelling by car, use energy-saving bulbs, and wear more clothes instead of turning up the heat.
Experts say we must do something NOW! If sea levels start rising even faster, it will be impossible to stop!
* how much CO2 we personally produce due to our lifestyles!

Ответ

3. 1 – T, 2 – T, 3 – F, 4 – NS, 5 – T, 6 – T.

4.

• changeable — unpredictable
• often — frequently
• getting warmer — heating up
• be all around sth — surround
• die out — become extinct
• in danger — under threat
• die from hunger — starve
• make smaller — reduce
• catches — traps
• disappear — vanish

5. Global warming happens because we burn fossil fuels which produce greenhouse gases. These will heat up our world by up to 3°C, which means big trouble. Mountain glaciers and the polar ice caps are melting fast! Parts of the world in low-lying areas may vanish completely in 100 years. Many animals are also in great danger like the polar bear, which may become extinct. Extreme weather such as hurricanes and droughts will also become more frequent.

6. Global warming is a serious problem because it makes the Earth hotter, melts ice caps and raises sea levels. As a result, some countries and cities may disappear under water. It also causes extreme weather and puts many animals in danger.

7. If animals could speak, they would ask people to protect their homes and stop polluting the planet. They would tell us that they are losing food, shelter and safe places to live because of global warming. Many of them are in danger of extinction.
