In recent years, the Earth has been getting warmer. Average temperatures have risen. Possibly this is natural, but probably we are causing it．Modern people use a lot of electricity and drive a lot of cars. This puts carbon dioxide into the air and helps to make the planet warmer. When we hear this news, we may smile. No one likes long, cold winters, but, unluckily, there are many bad points about a warmer Earth.

First, the ice at the Poles melts and becomes water. The result is that the sea level becomes higher. Low islands will disappear. Cities on the coast will be in danger from the sea. Will Tokyo, Bangkok, Hong Kong and Shanghai become like parts of Holland – lower than the sea? Possibly we will have to build walls to keep the water out. Typhoons will become even more dangerous and frightening.

Sadly, the second point is that storms will become bigger. Super-typhoons will be born in the Pacific and do great damage to East Asia. The same will happen to the Eastern United States.

As the weather changes, some places that now have rain will become dry. The farmers will not be able to grow plants. Maybe some dry places will become wet – we don’t know, but we will soon find out, and the change will cause many problems. There might be wars because of it.
