There is a growing evidence that solar variability influences the Earth’s climate in various intricate ways. Prolonged periods of reduced solar radiation in the past coincide with periods of extremely cold weather in the northern hemisphere and massive outbursts of solar energy alter the chemistry of the atmosphere. Understanding the Sun’s role in past and present regional climate variability is required to narrow uncertainties of future regional changes in climate warmed by greenhouse gas emissions.
At the Department of Geoscience we are following a very interdisciplinary approach to study the solar influence on our climate by combining:
Our work on solar influence on our climate is part of iClimate Pillar 1 led by Marit-Solveig Seidenkrantz and the Stellar Astrophysics Centre led by Jørgen Christensen-Dalsgaard.
