Life on Earth would not be possible without rain. Although water covers most of the earth, 97% of it is sea water. Rain supports life on land by supplying salt-free water that we can drink. Rain, or the lack of it has shaped and destroyed civilisations since antiquity, and now climate change is changing the patterns of rainfall with deadly effect.
