Global warming happens because we burn 1) fossil fuels which produce 2) greenhouse gases. These will 3) heat up our world by up to 3°C, which means big 4) trouble. Mountain glaciers and the 5) polar ice caps are 6) melting fast! Parts of the world in 7) low-lying areas may 8) vanish completely in 100 years. Many animals are also 9) in great danger, like the polar bear, which may become 10) extinct. Extreme weather such as hurricanes and 11) droughts will also become more frequent.

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.
