Climate Reconstruction from Subsurface Temperatures

  title={Climate Reconstruction from Subsurface Temperatures},
  author={Henry N. Pollack and Shaopeng Huang},
Temperature changes at the Earth’s surface propagate downward into the subsurface and impart a thermal signature to the rocks. This signature can be measured in boreholes and then analyzed to reconstruct the surface temperature history over the past several centuries. The ability to resolve surface temperature history from subsurface temperatures diminishes with time. Microclimatic effects associated with the topography and vegetation patterns at the site of a borehole, along with local… CONTINUE READING
