The Sun and Climate Change (Barrow-in-Furness)

Our Earth has shown wild variations in climate over the last few hundred million years. The ultimate driver of climate is the Sun, which has increased in luminosity by 30% over it's 4,500 million year current life. We will see how the sun works and how it influences the Earth and our climate on ever shorter time scales, including the 11 year sunspot cycle. Finally, we will see how recently CO2 has become increasingly important and look at the most likely future.
