  Global Warming  
 

For 2.5 million years, the earth climate has fluctuated, cycling from ice ages to warmer periods. But in the last century, the planet's temperature has risen unusually fast, about 1.2 to 1. 4 degrees Fahrenheit. Places which used to be abundant in snowfall have frequently experienced snow free winters. Drought lasts longer in some dry areas. People find that without air conditioners they could hardly work or fall asleep on hotter summer days.

Scientists believe it's human activity that's driving the temperatures up, a process known as "global warming".

However, is it really the fault of human activity? If yes, how have human beings driven the temperatures up? Are there any ways to solve this problem? What are they? As for every country, Is it necessary to take actions to stop global warming?

As members of human beings, let’s learn and figure out more information about global warming and try to do something to ease it.
