Terrestrial heat flow and global warming

Abstract

The variation of temperature with depth and the amount of heat escaping from the interior of the Earth through its surface are easily measured and give useful information on the ventilation requirements of deep mines, the deep structure of the Earth's crust and on global warming. This paper presents some temperature-depth data for boreholes in Zimbabwe. Thermal conductivity measurements on slices of rock from borecores are also examined and the linearity of some temperature-depth profiles are briefly examined to assess the possibility of global warming.
