Journal Article: Recent Warming In Southeastern Zaire (Central Africa) Inferred From Disturbed Geothermal Gradients

Abstract
Several temperature-depth profiles measured in Kasai and in Shaba provinces of Zaire using mining exploration boreholes exhibit a significant negative temperature gradient near the surface. This anomalous curvature which extends to 100-200 m depth could reflect the effect of variations in surface conditions. Applying the theory of heat conduction in a semi-infinite homogeneous medium, these profiles indicate a surface warming by 3-4°C. This warming is related to the effect of the environmental changes associated with the mining exploitation and the urbanization during the last 40-90 years.
