Mark Twain once said that everyone talks about the weather，but no one ever does anything about it.This was true in his day.But it may not be the case in today's world.In fact，humans have found many different ways to control the weather.
Cloud seeding（云催化）is a kind of technology that can control rain.It is done by spreading chemicals（化學(xué)物質(zhì)）like dry ice or silver iodide（碘化銀）inside of clouds，either by rocket or airplane.This changes the amount of water inside the cloud，which helps to control the amount of rain，the time when it rains and even where it rains.
This technology has helped to solve droughts（干旱）.It has also played a key role during important events.For example，China used cloud seeding in Beijing just before the 2008 Olympic Games in order to stop rain from falling during the event.
However，scientists are still debating（ 辯論）how to use this technology.On one hand，it is believed that it might have side effects（副作用）.For example，silver iodide may be bad for the envirjye.aiment.On the other hand，no two clouds are the same so every new experiment introduces new conditions.
In addition to controlling rain，scientists have also tried to find ways to weaken storms and hurricanes（颶風(fēng)）.Scientists at the US National Hurricane Centre Headquarters think it might be possible to control hurricanes by using lasers（激光）.Others believe that burning petroleum（石油）in a hurricane's path could slow the storms down.
