Well, it rains a lot in Ireland doesn’t it, so I’ll say that’s where the wettest place
on earth is.

OK, Neil. We’ll find out if that’s the correct answer later in the programme.
Neil
The first type of weather manipulation we’ll hear about is a way of getting snow
and rain out of clouds known as ‘cloud seeding’. Airplanes fly through the clouds
and spray chemicals to make water particles freeze and stick together as
snowflakes. These then fall as snow which builds up during winter before melting
in spring to help water crops.

Listen as Charmaine Cozier, presenter of BBC World Service programme, The
Inquiry, speaks with Professor Katja Friedrich, an atmospheric scientist at the
University of Colorado:
Charmaine Cozier
The first cloud seeding experiments took place in the 1940s. In the years since,
scientists are often accused of
meddling
with nature.
Professor Katja Friedrich
People are thinking, yeah, you’re putting some substances in the atmosphere
that should not be there. Usually I respond and say, every time you get into your
car, every time you get on an airplane you put substances in the air that don't
belong, so you're also
playing God.
Neil
Because everyone needs water, cloud seeding is becoming more and more
popular, with scientists from over fifty countries using the method to extract rain
from clouds. But some critics accuse these scientists of
meddling
with nature –
trying to change something which it’s not their responsibility to change.
Sam
In other words, they’re accused of
playing God
– acting as if they have unlimited
power and can do whatever they want.
