Abstract
Underground perturbations to the equilibrium geothermal gradient were used to reconstruct the ground surface temperature and energy balance histories at the continental surface. We reconstructed ground surface temperature and heat flux histories from temperature versus depth profiles measured at 558 sites distributed between 30° and 60°N in the northern hemisphere. Results indicate a mean surface heat flux gain of 18.0 mWm2 for the study area in the last 200 years. The heat gain is spatially variable and does not appear to have been persistent for the last 200 at every location in the northern hemisphere. We show that the ground has warmed about 0.5°K in the last 100 years
