Climate Reconstruction

The study of climatological data is inhibited by the availability of data. Inference about the climate over the past hundreds or thousands of years cannot be based on direct observations, which are only available for the past century or two. To obviate this problem proxies with many more observations, such as isotopes, tree rings and ice cores are used to predict the missing climate observations using calibration/inverse regression methods. In this talk we will investigate the assumptions and corresponding limitations of various calibration strategies and make suggestions about the use of such methods. If time permits, an example will also be given.
