Proxy data as evidence of past absolute temperatures...
How well do proxy data, such as tree rings or oxygen isotopes, predict past absolute temperatures?
How do proxy data, such as tree rings and oxygen isotopes, get transformed into absolute temperature?
Proxy data, such as tree rings, ice cores, or sediment cores, provide indirect measurements of past climate conditions. To translate this data into absolute temperature estimates, scientists use statistical techniques that relate the proxy data to obser…
