The Earth’s Internal Heat is Leaking into the Ocean in Amounts that Exceed the Global Warming Heat

Abstract

Global warming began increasing exponentially in the 1940s. However, the annual increase of the ocean heat content now greatly exceeds the annual increase of global warming heat, which is all of the heat that the Earth receives from the Sun. Thermal expansion of the Earth’s crust would cause the boundaries of its cracks to be enlarged. This enlargement is evidently causing some undersea cracks to admit more of the Earth’s internal heat into the ocean. The 50th percentile of 1.5°C global warming is estimated to arrive in the 2030s.
