About global warming, it is known that the ice sheet of the two poles is melting away. Still, there is a rarely known proof of global warming ---tropical expansion. The region of tropics has expanded towards the two poles for hundreds kilometers. This situation makes the weather unusual. In this poster, the red area of tropics invades the two poles with the melting drops falling down. Traces of wiping represent unusual weather in meteorological map. And it shows the effort that human beings make trying to save the world. The drops of tears along with withered leaves construct this ruining earth.
