A climate proxy is a tool that we use to reproduce previous fluctuations over significant parameters like temperature, rainfall, carbon dioxide, and many more.
The word Proxy can be defined as an intermediary or substitute, but most often it is used in the reference of a person give his/ her authority to someone else on their behalf. Proxy Data is therefore an information that is a substitute for direct observations of the Earth's climate.
