Oceans Heating, not Carbon Dioxide, is the Cause of Global Warming

About a million journalists, bureaucrats and evnironmentalists are promoting global warming issues assuming 0.04% of the atmosphere (CO2) is causing global warming while not knowing everything else in the atmosphere is a greenhouse gass also. It’s like saying ants on the road determine gas mileage.

The real greenhouse gasses include nitrogen 78%, oxygen 20% and water vapor 0-3%. They absorb and reemit infrared radiation just like CO2 does, and they conduct and convect heat which the sun produces. Nitrogen and oxygen do not absorb radiation as effectively as CO2, but they make up 2,500 times as much of the atmosphere. Water vapor absorbs in a comparable way to CO2, and there is up to 100 times as much of it in the atmosphere. Water vapor varies greatly, while CO2 changes slightly.

An important fact that is not being mentioned is that absorption of radiation in the atmosphere is not the only factor creating the greenhouse effect. Conduction and convection also add heat, and they are much more significant than radiation. Instead of these factors being considered, the entire greenhouse effect is being attributed to radiation absorbed by the micro components, as on the web site of the Union of Concerned Scientists.

There, the greenhouse effect is said to increase the temperature of the earth by 59°F. But since only CO2 and the micro components are mentioned, the impression is that they create the entire greenhouse effect. No way, shape or form does 0.04% of the atmosphere do all of that. The nitrogen, oxygen and water vapor are responsible for about 58.98 of those 59 degrees.

The very important effect of holding heat on the planet through greenhouse gasses is due almost entirely to conduction and convection, not the radiation effect attributed to CO2 and the micro components. Conduction and convection work like this: The sun’s heat strikes the surface of the earth as radiation and is converted into heat. This heat is in the soil, rocks, plants, water, etc. Then air sweeps over the surface and picks up the heat through conduction and convection, which heats the air.

Conduction means a heated molecule bumps into another molecule and causes it to pick up the heat as vibratory motion. Then the heated molecule is moved out of the way through convection, so another molecule can be heated in the same way. This is how the atmosphere is heated. Any heat added by radiation striking CO2 is only a trace amount.

Global warming is observed as weather changes including ice sheets melting, which are certainly real effects. But such effects are not being caused by CO2 in the air. They are caused by oceans warming plus black soot accumulating on the ice.

The uniform assumption has been that there could be no other cause of global warming than CO2 and other micro components of the atmosphere. That assumption is totally absurd. Evidence indicates that the cause of oceans heating is a hot spot rotating in the earth’s core. Ice age cycles point to this, because they have been cycling at exactly 100 thousand year intervals for the past million years. Environmental effects would be much more random. A rotating mass in the earth’s core would be cyclic.

The fact that the magnetic north pole is constantly moving shows that the earth’s core is heterogeneous and in motion. Fluids always are in motion due to convection, and many other forces could act upon the earth’s core.

Convecting fluids are never uniform in temperature. The temperature of air in a still room varies by several degrees due to convectional currents. Similarly, variations in the temperature of the earth’s core should be expected due to convection and nonuniformity of the earth’s surface, where loss of heat cools the core.

The earth’s core is constantly cooling resulting in an increasingly thick mantle. A billion years ago, the earths crust was so thin that collisions of tectonic plates did not create mountains. The evolution of mountains is an indication of the rate of cooling of the earth’s core.

Oceans heating may, or may not, indicate another ice age beginning. Mini ice ages do occur. But another ice age is due to occur at this time based upon the cycling of previous ice ages. If an ice age is beginning, how will it occur?

First, heating of the oceans will cause increased precipitation everywhere. There is evidence of slight increases in precipitation in recent years. Lake Michigan has been rising and flooding Chicago; and to control it, another canal was built around Niagara Falls during the early nineties.

After precipitation increases to a much higher level, and there is much more snowfall in northern areas, a trigger mechanism starts a precipitous drop in temperature. The most likely trigger would be a volcano which clouds the sky and prevents snow from melting. The unmelt snow would reflect away the suns heat triggering a rapid cool-down of the planet.

It is conceivable that no trigger mechanism would be needed to start an ice age, if high levels of precipitation cause more snow to accumulate than can melt. This could be a gradual process, as more and more snow accumulates each year.

For a time scale, it would probably take at least 50 years, and more likely 100-200 years, for rainfall to increase enough to start the reversal, if the present global warming is the start of another ice age.
