The climate on a planet is all about energy from the Sun. The power received in short wavelengths is transported and distributed by the climate system and ultimately emitted back into space in long wavelengths. Any change in this complex system is a potential cause of climate change. Looking at different planets and deciphering the climate history stored in natural archives on Earth provides a key clue on the role of the Sun in climate change.
