Abstract
Rock temperatures at shallow depths within the Earth are an archive of temperature changes that have occurred at the surface of the Earth in the recent past. Thus subsurface temperatures comprise a valuable complement to surface meteorological data in understanding the Earth's surface temperature history, particularly for times prior to the establishment of a worldwide network of meteorological stations. The subsurface observations are relevant to an assessment of the role of atmospheric greenhouse gases in the global warming of the 20th century.
