Earth's primary source of daily heat is the Sun. At sunset it turns off on the dark side of the planet. This side stays warm thanks to Earth's thermostate, its greenhouse gases, primarily carbon dioxide (CO2) at this point in history. Raise CO2 and the termpearture goes up; drop CO2 and the termperature goes down - - a thermostat. In 1896 the Swedish Chemist Sevante Arrhenius gave use the first mathematical model describing this natural process.
