Are We Nearing The End Of The Current Interglacial?
This documentary explores the theory that the earth was once a planet consisting of nothing but ice from pole to pole.
If this theory is correct, could there be a possibility of this happening to our planet again?

Yes, but not as you think ..
Average global temperature over time is climate ..
The earth is, and has been in an ice age for 35 million years (now in a cold interglacial period) due to the amount of oceans located out of the tropical zones and the warm sun’s inluence. This is a natural consequence of where the continents are located in relation to each other and how that, of course is dictating where the ocean currents can flow.
Got nothing to do with plant food or cow fart!!
(in the real world, of course!)
.. and:
If the “Greenhouse Effect” was real the thermal equilibrium point between earth and space would be at the earth’s surface.
The reason it is not is because of the Troposphere’s density (Mass, Pressures and Gravity) resulting in the Adiabatic Lapse Rate.
The Adiabatic Lapse Rate, which is proven to exsist, both measured and observed and the “Greenhouse Effect” can not exist at the same time in the atmosphere from the earth’s surface.
We also know that the earth’s “Black Body Surface” is at around 8 km altitude, measured from satellites, a fact that also disprove the “Greenhouse Effect”!
The “Greenhouse Effect” would only have been possible if the “Black Body Surface” was earth’s actual surface, and the thermal equilibrium point between earth and space also was at the earth’s surface.
The reason is, for the “Greenhouse Effect” to exist the earth’s surface would necessarily have to be cooled by radiation, which it is not, it is cooled by convection (in the real world, of course!).
Zero Carbon Dioxide (CO2) in the atmosphere is not possible due to Henry’s Law. Any gases that are removed will be compensated by outgassing from the oceans according to pressure, temperature: “At a constant temperature, the amount of a given gas that dissolves in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid.”
All this is confirmed by observations and have been known for decades.

The “new ice age” was first pushed by scientists in the 1970s, accompanying their cry that CO2 was causing it, by the way. Then we had the warm up where they pivoted their CO2 boogie man to be the reason for “globull warming.” Of the two, “globull warming” and the new ice age, only one is possible, and that one has been cyclical.
Yes, it is coming and sooner, rather than later. How soon? It is possible that we are already starting into the beginning of it. It won’t happen like the movies like to depict. It will take time as it settles in, but yes, it is coming. How severe? Only those that are born in the future will be able to tell. Of course, if we pursue “globull warming” and continue to destroy the energy sector of our civilization, there may not be any civilization to wonder about.

At the top of the troposphere conduction stops. Molecules too few and far between. Atmosphere can’t lose heat to space by conduction. Earth loses heat to outer space by radiation day and night. Atmosphere gains heat in day, loses heat to surface at night.

Hi Pierre,
Convection (not conduction where matter is in contact with other matter) does not end at the top of the troposphere. If you use the Search button at PSI to look up An interview with Tom Shula he shows how the Pirani Gauge shows that convection remains the dominate way energy is transferred into the thermosphere. It is at the top of the atmosphere where energy is lost into space at night causing the volume of the thermosphere to shrink.

In the troposphere the warmer air is at the bottom going up. In the stratosphere the warmer air is at the top coming down. The tropopause disconnects the two.
No convection/conduction possible between the 2.

Hi Pierre,
The levels of the atmosphere (troposphere, stratosphere, mesosphere, thermosphere) are a determination from the measurement by a thermometer and is not an accurate indication of the kinetic energy of the molecules.
A thermometer’s data comes from the collision gas molecules with it. It is measuring the momentum of the molecules, and since as the kinetic energy of the molecules increase the number of collisions decreases this produces two variables: mass and energy. In order to gat an accurate representation of the kinetic energy of the gas molecules you must divide the temperature reading at an altitude by the density of the gas molecules at that altitude to get the ke of a constant number of molecules instead of a constant volume of gas.
Instead of the zig zag and pauses flow of energy shown by the temperature graph you get a graph showing the ke increasing in a straight line in the troposphere (where water moderate the radiated energy) and in an exponential curve in the atmosphere above.
The contention that because N2, and O2 do not absorb visible or IR radiation, they do not absorb radiated energy is a violation of the laws of thermodynamics which states ALL matter absorbs radiated energy. It is the absorption of UV radiation from the sun (95%) and the conversion of this energy to ke by these gasses that heats the atmosphere. It is the sun not the surface of the Earth heating the atmosphere.
What is the sources of energy at the top of the stratosphere that is adding energy to the gas molecules in the mesosphere and troposphere?

Nice tirade. It still doesn’t change the fact that cold cannot heat warmer and that the Stratosphere is warmer than the troposphere. So, Earth can’t lose heat to outer space by conduction/convection. Since N2, O2 and Ar are IR transparent, and no gas can emit black body IR, then all that is left is black body IR radiation from the Earth’s surface to outer space.

Hi Pierre,
A law of physics cannot be broken. If there is an example where the law is contradicted then the law is invalid. The 2nd law of thermodynamics says that an object with less kinetic energy (cooler) cannot add energy (heat) an object with more kinetic energy (hotter). If a small car traveling at a high speed collides with a large truck traveling at a slower speed in the same direction the car will slow down and the truck speed up (law of conservation of momentum). This means the object with less kinetic energy (the car) is adding energy to the object (the truck) with more kinetic energy. The 2nd law is invalid. Object in elastic collisions transfer energy (v^2) not mass so the object with the greater velocity will add energy to the object with less velocity regardless of the mass. The flow of energy is from the object with the greater energy per unit mass to the object with less energy per unit mass regardless of the total energy of that object.
Since O2, N2, and argon are transparent to visible, IR, and longer electromagnetic waves the radiated energy they are required to absorb (LOT) must be shorter wavelengths. In the case of N2 and O2 this is UV while Argon absorbs X-ray and gamma radiation. All objects with energy emit radiated energy. When gaining radiated energy an object emits radiated energy. Since N2 and O2 do not emit UV or visible light they must emit IR. As the molecules move they create a disturbance in the electromagnetic field surrounding them as IR radiation.
The Earth is not a “black body” where energy loss is done exclusively by radiation. I again suggest you look up the interview with Tom Shula.

Hi Pierre,
You don’t see the problem of the Earth heating the stratosphere to a higher temperature than the troposphere?
