You have 1.5 minutes to read the text silently, then be ready to read it out aloud. You will not have more than 1.5 minutes to read it.
Scientists have noticed that the weather is getting worse and worse and the so-called extreme weather events are becoming more and more frequent. The explanation is short: the reason is global warming. What is global warming? Greenhouse effect is a natural feature of our atmosphere without which the life on our planet would be impossible. Certain atmospheric gases work as a kind of blanket, keeping the Earth warm. The amount of these ’greenhouse’ gases used to be more or less the same for centuries. But the industrial revolution broke this balance. Climate experts predict that in 30 years the global average temperature will rise by 2—3 degrees. Northern regions will be wetter and warmer, southern regions will be drier and hotter. Snow will melt in the Alps and other mountains and the water will cause floods. Sea levels will rise and lots of areas will disappear under water. So will some species of animals and plants.
