Climate change 'makes hurricanes'

The number of really big storms in the Atlantic Ocean is rising - and it may be because of climate change.

Hurricanes over the ocean happen twice as often than they did 100 years ago, according to some experts.

They say warmer seas and changes in where and how fast the wind blows - as a result of climate change - have increased the number of hurricanes.

But other experts think the number of hurricanes goes up and down over time, and at the moment they're on the rise.

They think the number of recorded hurricanes is higher than it used to be because technology makes it easier to spot them.

The people behind the report say that isn't the case, claiming the number of hurricanes each year has been steadily rising in the last century.

Experts say that 2007 will be a very active season with nine hurricanes forecast, of which five are expected to be intense.
