The Cloud Mystery

The Cloud Mystery is a documentary by Danish director Lars Oxfeldt Mortensen. It explores a controversed theory by Danish scientist Henrik Svensmark on how galactic cosmic rays and solar activity may affect cloud cover, and how this might influence global warming.[1] Also known as 'Klimamysteriet' in Danish.

This documentary presents the viewpoint of scientists who do not consider global warming is caused by anthropogenic production of carbon dioxide. It argues that cloud cover change caused by variations in cosmic rays is a major contributor to global temperature increase, and it claims that human influence and the effect of greenhouse gases have been exaggerated.

Where to watch it

The Cloud Mystery aired on TV2 (Denmark) in early 2008. It was also shown on Norway's NRK and on TV4 Fakta, (which can be viewed in Sweden and Finland.[2]) and on Arte (April 2. 2010, "Das Geheimnis der Wolken") in Germany.

Opinions

Danish engineering trade weekly Ingenøren found that the documentary gave a sober overview of Henrik Svensmarks theory, though it lacked scientific criticism.[3]

The documentary sparked a heated debate between supporters and critics of the political consensus that carbon dioxide is the prime cause of global warming.[4][5] However, the scientific results of Svensmark and Nir Shaviv, two of the protagonists, forming the basis of the documentary, have been criticized by Mike Lockwood and Claus Froehlich (see Galactic Cosmic Rays vs Global Temperature).[6][7]
