Global change: Climate's astronomical sensors
Michel Crucifix1
Abstract
A re-evaluation of the relationship between Earth's orbital parameters, ice-sheet extent and ocean circulation sets further puzzles for those trying to disentangle cause from effect in long-term climatic changes.
Earth's climate 'feels' the slow changes in the parameters of our orbit around the Sun. The great ice sheets of the Northern Hemisphere are one sensor, in that they are sensitive to the amount of solar energy they receive in summer.
