All around the world, we hear stories of terrible weather becoming even worse. For example, while forests in Australia are on fire, fields in Egypt are covered in snow. Environmental scientists explain that events such as these are due to climate (气候) change. They say that if we can’t protect the environment from pollution, we will surely destroy the Earth. However, there are still many people say that scientists have lied to us and there is no such thing as climate change. This passage will look at both sides of the argument to see who is telling the truth.
First of all, it is necessary to remember that scientific opinion has changed many times. For example, in the 1950s, the temperature in many countries seemed to be rising. Some of the world’s best scientists said that the world was becoming hotter. However, in the early 1970s the world began to freeze. As a result, scientists made new predictions: the world was not becoming hotter, but much colder. After the freezing winters of the 1970s, world temperature began to rise again in the 1980s and 1990s. Scientists changed their predictions again and decided that the world was now becoming too hot.
Some people have said that these examples show that climate change is not real. And it’s true that scientists have made mistakes. However, I don’t believe this means that they are wrong about climate change. It’s very difficult to make predictions about the future of weather. Although scientific predictions can sometimes be wrong, it does not mean that climate change is not real.
In conclusion, environmental scientists have not invented climate change. They have made mistakes but the important point is not whether the world is becoming hotter or colder but that climate is becoming worse. We have a chance to stop climate from changing and take action.
