Proxy (climate) - Wikipedia
WEBReliable global records of climate only began in the 1880s, and proxies provide the only means for scientists to determine climatic patterns before record-keeping began. A large number of climate proxies have been studied from a variety of geologic contexts.

WEBPaleoclimate data are climate records found in nature, known as proxy records. To access the records found in tree rings, corals, sediments, and ice, scientists use coring devices. From these cores, layers can be analyzed for their chemical composition and other clues of ancient temperature and precipitation patterns.
