Solar Variability and Climate
Does the Sun affect the Earth's climate?
Radiation from the Sun makes Earth a habitable planet. Fluctuations in the
solar radiative output are therefore likely to affect the climate on Earth,
but establishing both how the output of the Sun varies and how such
variations influence Earth's climate have proved tricky. Increased amounts
of data from the Sun and about the climate on Earth over recent years means
that rapid progress is being made. This work is aimed at understanding solar
variability and the Sun's influence on the Earths' climate.
We study solar variability on timescales of days to centuries.
The aim of this research is to understand the physical mechanisms
responsible for solar brightness variations and, finally, to predict future
variability of the Sun.
