(1958) A physicist at the Danish National Space Center in Copenhagen who studies the effects of cosmic rays on cloud formation. His research led to the hypothesis that solar activity and cosmic rays are an indirect cause of global warming.

In 1997, Svensmark and Eigil Friis-Christensen proposed a theory (called cosmoclimatology) that variations in cosmic rays caused by the intensity of the solar wind directly affect the earth's climate, and that this and not increases in atmospheric CO2 is the main driver in the Earth's recent warming.
