|“Our clouds take their orders from the stars,” says the Danish scientist Henrik Svensmark. That's the amazing and provocative discovery reported here.|
Most experts thought the idea was crazy. The film records ten years of effort by the small team in Copenhagen that, in the end, solved the mystery of how the Galaxy and the Sun interfere in our everyday weather.
It's provocative because Dr Svensmark's revelations challenge the belief of most climate theorists that carbon dioxide has been the main driver of global warming. As a result he has faced never-ending opposition.
But strong support for the cosmic view of climate change comes from astronomer Nir Shaviv and geologist Jan Veizer. In the film they tell how the Galaxy has governed the Earth's ever-changing climate over 500 million years.
Linking all the discoveries is the non-stop rain of cosmic rays – energetic particles from exploded stars that battle with the Sun's magnetic field to reach the Earth. Central in the story is an experiment in a Copenhagen basement. It showed how cosmic rays help to make chemical specks in the air on which water drops condense to make clouds.
