The Chilling Stars is a non-fiction book about the possible causes and effects of global climate change by Henrik Svensmark and Nigel Calder.

The authors argue that cloud cover changes caused by variations in cosmic rays are a major contributor to global temperature increases, and they state that human influences have been exaggerated.

They label their concept 'cosmoclimatology', and they attempt to look back through prior climate trends such as the Medieval Warm Period and the Little Ice Age.
