Climate proxies: Climate proxies are indirect indicators used to reconstruct past climate conditions when direct measurements were not available. Ice cores serve as one type of climate proxy.
Paleoclimate: Paleoclimate refers to Earth's climate in the distant past before instrumental records were available. Ice cores provide valuable information for studying paleoclimate.
Vostok Station: Vostok Station is a research station located in Antarctica where one of the longest ice cores ever drilled was obtained. It has provided crucial insights into Earth's climate history.
