Panel Discussion on the Solar and Climatic Relations
On a long time scale, over thousands of years, changes in the orbit of the Earth around the Sun have been associated with drastic changes in the Earth’s climate. The reason for these changes is thought to be changes in the received solar energy and in particular its distribution on the Earth’s surface. Although small, these changes seem sufficient to have initiated large oscillations in the Earth’s climate in a manner still poorly understood. Similarly, variations in the activity of the Sun itself may have an influence on the climate of the Earth, and a number of correlations have been presented that indicate the possibility of a direct link. However, no convincing physical mechanism has yet been presented that explains the observations.
