This talk will explore aspects of military communications during WW2, starting with the German use of radio to enable Blitzkrieg (lightning warfare) and then move on to review the value of radio interceptions to feed Bletchley Park with messages to decode. We will then then explore the communication required to support D-day and the Allied advance from the beachhead. The talk will also address Operation Market Garden and the challenges which poor radio communications presented and discuss the reasons for this. An underlying theme will be the role of the Royal Signals as the British Army' specialist communications branch

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.
