Temperature Regulated Cooling Dominates Warming and Why the Earth Stopped Cooling At 15°C

Abstract

"It is said that the Earth’s surface temperature variations are controlled by [human-induced] greenhouse gases1. This is not the case. When cooling systems dominate, surface temperatures are set by the cooling system and not by the system that is warming the surface. On Earth the surface cooling system dominates; temperatures are set by the natural cooling system. The strength of natural surface cooling is set by temperature. Adding greenhouse gases to the atmosphere does not make any difference for surface temperatures. Their initial warming effect is neutralized by extra surface cooling and by a diminished uptake of solar energy. The cooling system dominates.

Introduction

The Earth was assembled from ‘space debris’ orbiting the Sun. Gravity made objects like ‘space rocks’ and ice comets coalesce. When accretion took place, gravity melted all assembled objects and a big ‘snooker ball’ of molten material was built. The proto-Earth was also warmed by the Sun, but eventually it cooled down until ‘energy in’ equaled ‘energy out.’ Currently, the surface of the Earth is at balance at around 15 degrees Celsius. A similar planet, with no oceans or atmosphere would have stopped cooling at around 5.3 degrees Celsius, if it reflected no sunlight. Why did the surface of the Earth stop cooling at 15 degrees? And why didn’t the Earth’s surface stop cooling at, for example, 50 degrees Celsius?" ...
