Abstract
The average heat loss from the Earth's interior is calculated from heat-flow values and tectonic models of sea-floor spreading. The value of 10.2 × 1012 cal/s (±1 5 percent) is about 32 percent larger than previous estimates, mainly due to the previously ignored contribution from the cooling lithosphere. The principal uncertainty derives from unknown parameters of the oceanic lithosphere.
