I probably would have been faster had I joined the Army before turning 28, especially before intentionally gaining weight at 24.

I have always wondered how soldiering would have been had I still weighed 153 pounds. Running should have been easier, but my SAW and ruck would have been relatively heavier.

Mars and Terra are warming. My astronomy professor always said "One is an anomaly. Two is a pattern," so I tried to find out if our inward neighbor was warming.

There seems to be a conspiracy to cover up data regarding Venus getting warmer.

This guy asked the same question. I do not feel that anyone really tried to answer him.

Someone replied "It has been claimed that CO2 will only absorb radiant heat at 15 microns. Yet radiant heat can be between about 7 to 20 microns. If this is true then surely more man made heat is escaping from the earth than is absorbed."

I tried to look into that and found this: https://principia-scientific.org/doe...ide-trap-heat/

In physics, specific heat (cp) is the amount of heat in joules (J) required to raise the temperature of one gram (g) of a given substance one degree centigrade (°C). The specific heat of air and CO2 in J/g/°C are:

Air – 1.005

CO2 – 0.709

All things being equal, a bottle filled with CO2 will always warm faster and to a higher temperature when heated than does a bottle filled with regular air because the specific heat of CO2 is lower than that of air. Consequently, less energy is needed to to raise one gram of CO2 one °C than one gram of air one °C.

The big debate about CO2’s effect on global surface-level air temperatures is what will happen when atmospheric CO2 doubles in concentration from pre-industrial times, i.e., increases from 0.026% (280 ppm) of the atmosphere to 0.056% (560 ppm).

He talks about a school experiment where a teacher has a bottle of air and one of carbon dioxide, places both under a heat lamp, and shows that the bottle with CO2 warms up faster than the bottle of air. Supposedly, the glass lets infrared into the bottle, but does not let it back out.

He also argues that water vapor does not create a "greenhouse effect," but instead a "swamp cooler effect:"

H2O cools the surface when it is evaporated into water vapor
H2O in the form of water vapor increases the emissivity of the air and thus enhances the ability of heat to move up the atmospheric column via IR radiation
H2O when cooled at altitude condenses into clouds which shades and thus further cools the surface.
H2O within clouds precipitate rain and snow, which further cools the ground
Ground water is then evaporated again as the water cycle repeats and repeats and repeats.

He then compares different regions at the same lattitude, dry versus wet:


Someone argued that water vapor is never a gas, but instead a volatile liquid.

Someone else argued:

CO2 has a mass of 44.01 versus air with a mass of 28.966.

44.01/28.966 times 0.709 = 1.08 which is very close to the specific heat of air. Therefore CO2 actually requires slightly more energy to increase in temperature than ordinary air !

Why does he put a space before his exclamation mark? He does this every time, I just did not quote them.

Someone replied to him:

One known factor not considered is the thermal conductivity of the air 0.026 (watt/mK) and of the carbon dioxide 0.017 (watt/mK). The thermal conductivity of carbon dioxide is less because its average velocity at the same temperature is less than that of nitrogen or oxygen even though the average kinetic energies are the same.

Another:

CO2 absorbs IR radiation primarily at 12 to 15 microns, inside what is known as the “Water Vapor Window”.

Somebody else wrote:

Heat is always moving because heat is kinetic energy, energy of motion. What CO2 does do is it absorbs and then 100 attoseconds later, emits Infrared photons, or radiant heat [...] in every direction equally. Thus, when CO2 i the air absorbs the morning sunlight, it emits most of it out sideways away fro the Earth, essentially blocking 2/3rds of the incoming Sun heat.

Wouldn't the heat bounce from one CO2 molecule to another? Not trapped in a bottle, but trapped in a cage?

One last comment:

Wiki/Water_Spectrum_Absorption > shows the four vibrational and rotational modes

of energy absorption for water molecules. Carbon Dioxide absorption has a single,

linear vibration mode, lasting a billionth of a second in three spectral bands.

So, water vapor absorbs more heat than CO2?

This article states that Mars is not getting warmer, instead it is rotating differently, and ice is melting in one spot and forming in another: https://www.washingtontimes.com/news...ce-age-retrea/
