Cosmoclimatology Theory of Climate Change
Svensmark detailed his theory of cosmoclimatology in a paper published in 2007. The Center for Sun-Climate Research at the Danish National Space Institute "investigates the connection between solar activity and climatic changes on Earth". Its homepage lists several publications earlier works related to cosmoclimatology.
Svensmark and Nigel Calder published a book The Chilling Stars: A New Theory of Climate Change (2007) describing the Cosmoclimatology theory that cosmic rays "have more effect on the climate than manmade CO2":

- "During the last 100 years cosmic rays became scarcer because unusually vigorous action by the Sun batted away many of them. Fewer cosmic rays meant fewer clouds—and a warmer world."
A documentary film on Svensmark's theory, The Cloud Mystery, was produced by Lars Oxfeldt Mortensen and premiered in January 2008 on Danish TV 2.
In April 2012, Svensmark published a remarkable expansion of his theory in the Monthly Notices of the Royal Astronomical Society
In the new work he claims that the diversity of life on Earth over the last 500 million years seems remarkably well explained by tectonics affecting the sea-level together with variations in the local supernova rate, and virtually nothing else. This suggests that the progress of evolution is fundamentally affected by climate variation depending on the Galactic Cosmic Ray flux.
The director of DTU Space, Prof. Eigil Friis-Christensen, commented: "When this enquiry into effects of cosmic rays from supernova remnants began 16 years ago, we never imagined that it would lead us so deep into time, or into so many aspects of the Earth's history. The connection to evolution is a culmination of this work."

Famous quotes containing the words theory, climate and/or change:
“A theory if you hold it hard enough
And long enough gets rated as a creed....”
—Robert Frost (1874–1963)
“A tree is beautiful, but what’s more, it has a right to life; like water, the sun and the stars, it is essential. Life on earth is inconceivable without trees. Forests create climate, climate influences peoples’ character, and so on and so forth. There can be neither civilization nor happiness if forests crash down under the axe, if the climate is harsh and severe, if people are also harsh and severe.... What a terrible future!”
—Anton Pavlovich Chekhov (1860–1904)
“Men must be capable of imagining and executing and insisting on social change if they are to reform or even maintain civilization, and capable too of furnishing the rebellion which is sometimes necessary if society is not to perish of immobility.”
—Rebecca West (1892–1983)
