| Zusammenfassung |
Progress in understanding climate variability through the last millennium
leans on simulation and reconstruction efforts. Exercises blending both
approaches present a great potential for answering questions relevant both
for the simulation and reconstruction of past climate, and depend on the
specific peculiarities of proxies and methods involved in climate
reconstructions, as well as on the realism and limitations of model
simulations. This paper explores research specifically related to
paleoclimate modeling and borehole climatology as a branch of climate
reconstruction that has contributed significantly to our knowledge of the low
frequency climate evolution during the last five centuries.
The text flows around three main issues that group most of the interaction
between model and geothermal efforts: the use of models as a validation tool
for borehole climate reconstructions; comparison of geothermal information
and model simulations as a means of either model validation or inference
about past climate; and implications of the degree of realism on simulating
subsurface climate on estimations of future climate change.
The use of multi-centennial simulations as a surrogate reality for past
climate suggests that within the simplified reality of climate models,
methods and assumptions in borehole reconstructions deliver a consistent
picture of past climate evolution at long time scales. Comparison of model
simulations and borehole profiles indicate that borehole temperatures are
responding to past external forcing and that more realism in the development
of the soil model components in climate models is desirable. Such an improved
degree of realism is important for the simulation of subsurface
climate and air-ground interaction; results indicate it could also be crucial
for simulating the adequate energy balance within climate change scenario
experiments. |
