The diagram shows the weather changes in the global climate. It tells us that the global average
temperature has increased by 0.8℃ from 17℃ in 1951 to 17.8℃ in 2001. Thus, we can come to
a conclusion that our earth is getting warmer and warmer.
As far as we know, the major reason for global warming is due to human activities. Firstly, the
use of fossil fuels by industry releases greenhouse gases. Moreover, cutting down forests means
that less carbon dioxide can be changed back into oxygen. As a consequence of global warming,
the sea level is rising. And people are suffering more extreme weather. The increase in temperature
is also causing much damage to the balance of nature.
It"s high time that we should take measures to protect our earth. Not only can, we control the
releasing of carbon dioxide, but also we can be encouraged to use new energy, such as solar energy.
In a word, only in this way can we make our earth a better place for our human beings. |
