Save our planet

Tornado is one of the world's climate changes. There are many others.
The number of storms is increasing and there are more huricanes.
There are more floods in some parts of the world, and there's much less rain in others. We know that these happen because global temperatures are rising and many people belive the weather will get worse in the future. The problems of climate change won't go away unless we do something about the causes.
Scientists still do not know enough about the reasons for these temperature changes. Some say that these types of climate changes are natural, but most scientists think human activity is the problems.
Scientists believe that if the temperatures continue to rise, the ice at the poles will melt. If the ice melts, sea levels will rise. Some island might disappear completely, and there might be floods in coastal cities. All this means that unless we do something to stop global warming now, there may be many other dramatic changes in the future.
