½â´ð The diagram shows the weather changes in the global climate£®It tells us that the global average temperature has increased by 0.8¡æfrom 17¡æin 1951 to 17.8¡æin 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 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£®
