Lunar Warming and Global Cooling  

The Moon Effect Called the Greenhouse Effect on Earth

Despite the fact that NASA scientists are among the foremost promoters of catastrophic global warming due to man's use of fossil fuels and carbon dioxide emissions, NASA scientists have long known that the moon exhibits a warming effect which is similar to the effect which on Earth is said to be due to greenhouse gases.  Calculations in anticipation of the Moon Landings indicated that such a net warming effect should be expected and subsequent measurements on the moon's surface during landings confirmed this effect.  What is this effect due to?  We will discuss that below, but let us first examine the greenhouse effect.

It is commonly claimed that the Earth can be treated as a black body which is in equilibrium with the incoming radiation of the sun and the outgoing radiation into space from the black body Earth.  Calculations based on this simple model indicate the Earth has an average temperature 33C warmer than it should be.  It is said to be this much warmer due to its atmosphere, in particular due to water vapor primarily and other greenhouse gases such as CO2 secondarily.

A black body absorbs 100% of the energy that falls upon it and it re-emits energy based on the Stefan-Boltzmann formula.  When the black body is in thermal equilibrium, it emits energy at the same rate as energy is absorbed.  The theory assumes the outer surface of the black body is extremely thin, though this matters little to the calculation provided the underlying material has a fixed temperature gradient with the maximum temperature on the outside surface and a radiation absorption length which is extremely short.  For the surface depth to be unimportant, the amount of radiation falling on the surface should also not be changing in time.

These are not conditions satisfied by the moon or the Earth.  The moon surface heats up when radiation from the sun is incident upon it and that heat is conducted downward into the rock and dust of the moon surface.  The local topography of the surface, the distribution of rock and dust minerals, and the local particle sizes will all affect the local depth to which heat will penetrate, the absorptivity of the surface, and the emissivity of the surface.  In addition, the moon rotates so that the amount of energy from the sun, or reflected from Earth, varies over time upon a given area.  Thus, the gradient of energy below the surface will change as the surface cools when sunlight is not incident on it.  This sub-surface heat reservoir acts to warm the surface.  This introduces a heat convection source, which is not consistent with a black body radiation source.

The situation with the Earth is much worse.  All of the problems of the moon exist for the Earth.  To which are added the fact that the Earth has a substantial atmosphere in which the radiation absorption length is long.  Large thermal gradients will exist in the atmosphere even if it were of uniform composition.  It is not.  The most important way in which is not is the wide variation of water vapor in it, and still worse, the wide variations in cloud cover.  The absorptivity of the atmosphere for solar radiation varies from place to place, as does the emissivity.  Compared to the moon, the Earth's surface also has a great variability in the important properties of absorptivity and emissivity from area to area.  The South Pacific is different than the Rocky Mountains, Antarctica is different than the Great Plains, the Siberian tundra is different than the Sahara or the Amazon rain forest.  These differences alone would create great flows of heat in convection currents even if the Earth did not rotate.  In addition, there is much more variation in the depth to which heat will be absorbed in the land areas than on the moon due to more varied compositions.  Then, the oceans and water bodies hold very large amounts of energy which is absorbed to comparative large depths straight from incoming radiation and then further distributed in convection currents to great depths and over large lateral distances.  All of these large heat flows on Earth cause it to fit the requirements of a black body radiator very poorly.

Let us return to the much simpler case of the moon.  It has no atmosphere, no vegetation, and no oceans to muck things up.  There is a paper by Martin Hertzberg, Hans Schreuder, and Alan Siddons called A Greenhouse Effect on the Moon?, which Dr. Hertzberg was kind enough to draw my attention to in early June and I have had in mind discussing its very important results ever since.  The paper notes that NASA scientists needed to calculate the expected temperatures on the moon's surface prior to a landing.  Taking into account the changing radiation on a point on the surface and assuming no heat was absorbed into the surface, the first result is:


When no radiation is incident upon the spot on the surface, the temperature falls to absolute zero!  A later calculation took into account some light reflected from Earth when sunlight was not incident.  Under that condition, the low temperature was between 30 and 40 Kelvin.  But the moon does absorb heat for some depth into its surface and that heat flows to the outer surface as the outer surface cools at "night."  So, what did NASA find the temperature profile over the course of day and night to be?

The maximum temperature of the day is no longer noon, since at noon the rock and dust has not yet reached the maximum degree of sub-surface warming.  The maximum temperature is actually afternoon, just as it tends to be on Earth.  The blue areas in the graph show when the surface temperature is cooler than in the simple black body calculation in the first graph, while the orange areas show when the temperature is warmer.  Early in the day, the surface temperature is cooler because surface energy is flowing more rapidly into the cooler sub-surface rock and dust.  Late in the day and through the night, the temperature is higher than expected by the black body calculation because heat is flowing to the surface from the sub-surface.  The average temperature is raised considerably, because while there is a slight depression of the maximum temperature in the day, there is large increase in the nighttime temperature.  By day the average temperature is cooler by 20C, but at night it is warmer by 60C.  The average temperature is raised 40C!  If the moon had an atmosphere, this would be called the greenhouse effect.

Because the Earth has an atmosphere and because it has oceans over 70% of its surface and the oceans retain huge reservoirs of heat, the variation in temperature throughout a day is much less on Earth than on the moon.  But, there is still a rise in the average temperature due to heat convection on land, in the oceans, and in the atmosphere.  Heat convection in 3-dimensions creates an effect that looks like the greenhouse effect.  Similar effects are observed for all of the planets.

It appears that if any "greenhouse effect" occurs due to CO2 in our atmosphere, that effect is very small compared to the 3-dimensional effects of distributed heat with convection heat transfer.  That this is so has long been known by NASA, which nonetheless has played a very major role in the promotion of AGW alarmism on the basis of greenhouse gases!  Once again, we find that government is not worthy of our trust.  It has promoted terrible damage to our economy on the basis of this greenhouse gas catastrophic warming nonsense.  It has been willing to put companies and many employees out of business.  It has been happy to promote programs for alternative energy that greatly increase our energy costs and threaten to degrade the quality of our energy systems in use.  It has declared CO2 a pollutant and is about to start draconian regulations at great expense, with huge additions to the bureaucracy, and terrible hours of additional paperwork, expert fees, and lawyer fees for many, many companies.  Cap and trade schemes have been put forth in its name which will enrich the politically connected, while the average family sees its energy bill go up between $1,700 and $3,500 a year.  As Obama says, our energy costs will necessarily skyrocket.

Obama may be fine with skyrocketing energy costs, but you and I should be very angry about it.  Not only is the basis in CO2 greenhouse gas theory all wrong, but none of the remediation schemes are even thought likely to benefit the climate in any significant way.  Even if the greenhouse effect were substantial, which it is not, all of the energy use restrictions are all pain and no gain.  Are we all suddenly masochists?  Don't we all have lives to live, places to go, and things we want to make or own?  What is this madness that has overcome so many of us?  Well, for some it is simple robbery.  There are those who are very happy to take advantage of the fact that most people and most Americans in particular, do not know enough science to understand how badly the wool has been pulled over their eyes.  There are no two ways about this.  The catastrophic man-made global warming scare has been a massive fraud.  There are many very evil people promoting this fraud and most of the impetus for it is coming from Democrats.  It is very important to make them pay in the elections of 2010 and 2012.

Glacial advance. Demand a refund of your anthropogenic global warming taxes now. The climate is cooling and it will accelerate.
The following image is from a brief article by Dr Roy Spencer on WUWT discussing the rapidity of the change from El Nino to La Nina.


The main actors that dictate the N. hemi climate are the El Nino Southern Oscillation and the N. Atlantic oscillations. The Arctic Oscillation looks to be a responder rather than an initiator. The Pacific (multi) Decadal Oscillation can be considered a climate meter in the long term. It reinforces or moderates ENSO moods.

Well folks, I guess that's it for this interglacial. You'll be happy to know it was Edmund de Rothschild that decided we would have a climate scare. Just for the profit you understand, no harm intended.

How Edmund de Rothschild Managed to Let 179 Governments Pay Him for Grasping Up to 30% of the Earth
.
Summary: After Edmund de Rothschild's statement, without basis, at the 4th World Wilderness Congress in 1987, that CO2 is the cause of a non-existent global warming - and that combating it needs money (our money), he founded the World Conservation Bank for this reason. In 1991 its name was changed to The Global Environment  Facility (GEF). The purpose of this facility is to lend money to the poorest countries, printed by the IMF out of thin air, and with the guarantee of our governments. The facility takes wilderness areas with mineral riches as security. The GEF money is then to flow back to our governments as reimbursement for paid loans. I.e. We give away our tax money. For what? When a country cannot repay loans to the GEF it must give up a piece of its territory to the Rothschild banks (GEF, IMF, World Bank) - up to 30% of the Earth are meant. If land cannot be offered as collateral the country  must starve (Haiti, Argentina and others). Rothschild´s  stroke of genius was that he had his GEF smuggled into the UN system at the Rio UN Summit in 1992 by his friend, Maurice Strong. So now high-ranking ministerial officials from 179 countries are in the the council of the bank - blessing Rothschild grabbing the world! This article brings interviews with a man who was a participant at the 4th World Wilderness Congress,a man  who knows what happened there and knew Rothschild  personally - as well as David Rockefeller, who tried to threaten him to silence about what he had learned at the Wilderness Congress. The GEF is to manage the money  just promised to the developing countries in Copenhagen (100 billion dollars a year from 2020 - 30 bn over the next 3 years)  with the help of the World Bank. However, Rothschild does not leave it there. He and his henchmen are now joining the race of certain governments (China, Saudi Arabia), to buy up large areas of farmland  in  developing countries, having the crops  transported back to the home countries. This leaves the locals, already starving, with much less crops available - with food prices rising rapidly - which is exactly Rothschild's expectation. This makes people flee from Africa to Europe. Food prices have doubled in the past year or so - so that many people in Haiti before the earthquake, could not even afford to buy mud pies with minimal nourishment. And so it goes on. This is the ultimate goal of Rothschild's New World Order.

Next time you look at your energy bill, pay for cigs and beer, buy food, get knocked over by the tax from your wages, need a mortgage to fill up with petrol, you know who to blame.
