Document Summary
Characteristics of climate: varies across space & time, occurs on different scales spatial & temporal scales. Variables are mutually influential: dependant on historical events. Impact of a variable depends on pre-existing conditions: can only be understood by proxy data. Implications for reconstructing climate: must specify temporal/spatial scale of analysis. Ie. not all data sets are of equal valuable at all scales: Not all data sets are available at all scales: past climate difficult to reconstruct: Nature of effect on climate is obscured due to impact of all variables. Climate reconstructed through two related approaches: theoretical climate modeling. Goal use understanding of modern climate systems. To generate a computer model that can be applied to past. Application of uniformitarian assumption identify natural principles active in the present. Not the same thing as analogy use of a specific modern climate to model the past. Modern dates are then replaced by ancient values (same variables)
