afraid worse is to come: people who study earth's climate have found that
as it warms
up, the weather is going to get more violent and unpredictable. Hurricanes,
for example, will become more powerful -- a big worry for people living
in the south of the United States and in the tropical Pacific or Indian
ocean areas like the Philippine islands and Bangladesh. Deserts
are increasing and places like the Great Plains of America will get drier.
Rain will be heavier in other parts of the world so there will be more
floods. These things have already started to happen.
