Since the last meeting, the Museum projector has been fixed, so we can now see pictures in colour! (For those who missed the July meeting, everything was a deep, deep green….) So Stuart Atkinson was able to show his latest NLC photos to best advantage. After 10 years in Kendal, he has finally managed to capture NLC above the Castle, and it was truly a gorgeous image.
Richard Allen (the son of our ex-treasurer David Allen, it turns out) gave a nicely-pitched lecture on how the size and orbit of the Earth determine the weather patterns that exist on it, and also how the climate has been affected in the past by things such as the tilt of the Earth’s rotation axis to its orbital plane (why we have summer and winter) and the changing eccentricity of the Earth’s orbit over time. He finished with a sobering summary of the current evidence that mankind’s activities on Earth have very recently upset long-standing balances between the carbon dioxide entering and leaving the atmosphere (man-made climate change).
