sunlight only accounts for less than ten percent of earth's heating.

i am, far more concerned where the other 90+Percent comes from. the nuclear reactions, are fairly stable source. but am more concerned as to how low the last two solar maximums were, resulting in a reduction of heat from the magneto-induction into the earth's core.

which suggests, a period of delayed global cooling and drought. since it takes years, for this effect to reach the surface.

even if the swelling of the earth's atmosphere, is more immediate effecting the wet and dry periods. when the earth's atmosphere swells, from ionization it absorbs more moisture, when it collapses from lack of ionization it releases moisture.

and what alleged as men have done, has little or no effect on these internal and external forces of nature. and the mystery is, why does the oxygen levels remain stable at over 21% regardless of what alleged as fallible men have done. and scientist do not even have a clue what is regulating it
