The knowledge of the present-day underground temperatures may be important in the assessments of the past climate change. The method of inversion of the temperature-depth records into the ground surface temperature history is briefly introduced by showing an example of synthetic data and illustrated by a review of existing results obtained from the inversion of temperature logs measured in holes in the Czech Republic. Underground temperatures observed in holes of the depth of at least 1000-1500 m seem to confirm the preinstrumental climate pattern of the past several thousand years. Most of shallower temperature records (500-800 m) revealed general warming of climate followed the Little Ice Age of the 17-18th centuries and a pronounced increase of the soil temperatures by at least 1 K since the beginning of this century.
