How does technology allow us to see infrared light, and how is CO2 connected to global warming? Don't dismiss this article, because it contains new evidence. Night vision scopes use thermal imaging, but they don't "see through" walls. Instead, they detect heat signatures emitted by objects, including people, and translate those heat signals into visible images.
Thermal cameras also can’t detect infrared light through walls; they capture temperature differences on the surface of a wall, not what's behind it. Let's dive into a more detailed explanation and find a different way to explain global warming.
Thermal Imaging Technology
Thermal imaging devices detect infrared radiation emitted by objects. The hotter an object is, the greater the intensity and frequency. We can take photos of infrared light with film or an infrared camera.
Passive thermal heat in an object is transferred by conduction or kinetic energy. In addition, all objects emit infrared light, and several types of heat can transfer simultaneously.
For example, a boiler system in a house uses a furnace to heat a container of water, and the hot water is pumped into radiators where the heat transfers to the air molecules in the room by conduction and convection. A thermal camera can see the temperature variations in the water lines, and an infrared camera detects infrared light from the radiators.
Thus, there are two or more types of heat radiation. The passive heat from objects transfers heat by conduction, plus all material objects emit infrared electromagnetic radiation. Note that gas doesn't emit infrared light…
A blackbody absorbs and emits all frequencies. There's a meaningful distinction between "thermal radiation" and "infrared radiation.” The main point is that thermal radiation transfers heat by direct contact with a solid, liquid, or gas, and infrared radiation travels at the speed of light in space and the atmosphere.
Infrared light is electromagnetic radiation with a specific frequency in the range of 0.3 THz to 400 THz that exists in any type of process. Infrared radiation can also be called infrared light, infrared heat, or infrared waves. There are many ways to make infrared radiation. The thermal transfer of heat also has many types of radiation.
This Image shows three different types of electromagnetic radiation. However, thermal transfer of heat can include many more types. (Public domain image) unknown source.
Heat Signatures of Matter
Thermal cameras can detect subtle temperature differences, even through walls, as heat from objects behind the wall radiates infrared light, which strikes the wall. Hence, the heat on the wall outside is visible to a thermal camera.
If the wall is thick and insulating, it can block or reduce the heat penetrating the wall. While thermal cameras can detect heat signatures radiating through walls, they cannot see objects or people through the walls. They primarily detect heat patterns and anomalies on the wall's surface.
Some night vision devices use active illumination. The camera emits an infrared light to illuminate the scene. It can allow them to see objects in the dark, but it doesn't allow them to see through walls.
With the proper night-vision equipment, you can see a person standing 180 m away on a moonless, cloudy night. However, if it's raining, the environment is at an equal temperature. Moreover, it's difficult to detect people or animals from the ambient temperature in a hot tropical climate. Night vision works in two ways, depending on the technology used.
Image enhancement technology works by collecting the tiny amounts of visible light, with the lower portion of the infrared light spectrum present in all matter, and amplifying them to the point that a monitor can observe an image.
Thermal imaging technology captures the upper portion of the infrared light spectrum emitted by objects. Hotter objects like warm bodies emit more infrared light than cooler objects like trees or buildings.
Planck's Blackbody Spectrum
A blackbody is an idealized object that absorbs and emits all electromagnetic radiation it comes in contact with. The radiation emitted by a blackbody follows Planck's Law, meaning the spectrum of the emitted radiation is determined only by the temperature.
Thermal heat energy in matter is converted into low-frequency infrared light from kinetic vibrations and random movements of electrons and molecules in matter. This heat is transferred to other objects by conduction.
Additionally, electromagnetic infrared radiation is emitted from all matter by the vibrations of charged electrons and proton particles within an object. Thus, radiation can exist in many ways from one object.
For example, a campfire emits infrared light, visible light, ultraviolet light, and thermal conduction to the air. Wildfires can seriously increase global warming because all the heat is immediately released into the atmosphere. CO2 molecules can absorb the infrared radiation, and air molecules absorb the kinetic energy of hot air, preventing Earth's radiative cooling.
Thermal Radiation and Global Warming
Understanding how heat is transferred from objects to greenhouse gases is paramount to the global warming theory. Scientific research says, "CO2 molecules trap heat in the atmosphere instead of radiating it to space." Let's look into that theory.
Sunlight contains 50% infrared, about 49% visible, and some ultraviolet light. The infrared light heats the Earth's surface, which is like a blackbody and can absorb and emit all thermal and infrared radiation.
Matter is composed of charged particles, such as protons and electrons. The kinetic interactions among molecules in matter result in charged acceleration and dipole oscillation. This results in the electrodynamic generation of coupled electric and magnetic fields, resulting in the emission of infrared photons from all objects.
The Earth cools by conducting heat to air molecules. A CO2 molecule can absorb infrared light directly or through kinetic energy conduction. The CO2 molecule absorbs infrared light through its dipole moment and transfers the thermal heat to other objects by conduction, convection, and kinetic energy.
When a fast-moving CO2 molecule collides with a slower one, it can transfer some of its kinetic energy to the slower molecule. This transfer can change the speed of both molecules, effectively spreading heat energy from areas of higher temperature to regions of lower temperature.
Gas molecules can absorb infrared light radiation, but they can't emit infrared light because gas molecules are not blackbodies. CO2 and other gases absorb infrared light, but they can't transfer infrared light except by conduction and kinetic energy. That's the law of quantum electrodynamics.
This is existing science, not some kind of radical concept. It's confusing because gas molecules can absorb visible sunlight and emit visible frequencies.
An example of this process happens when solar radiation enters the atmosphere and strikes the electrons in gas molecules. The molecule's electron emits another photon with the frequency of the molecule. The six different types of gas molecules in the atmosphere emit photons of their molecule's frequency, and when combined, they look blue. That's the reason why Rayleigh scattering makes the sky blue.
Unraveling the Correct Reason for Global Warming
Sunlight enters a molecule's electron and emits visible light.
In my previous article, I explained the quantum mechanics of light and how electrons emit visible light. Molecules, however, can absorb high-frequency infrared light and low-frequency thermal radiation, but do not emit infrared light.
The only way CO2 molecules can transfer heat is by conduction and kinetic energy. This property of carbon dioxide explains why it's not a major contributor to global warming any more than the other air molecules. The central fact is that CO2 and other molecules cannot emit infrared light, but can absorb it. It's challenging to explain the complex nature of light since we have not understood the quantum nature of light.
The theory that greenhouse gases emit infrared light back to Earth and prevent heat from escaping Earth needs evaluation. CO2 isn't the primary cause of global warming. However, the amount of carbon dioxide emissions increases when the temperature increases.
The increase in CO2 is caused by eight billion people cooking and heating their homes, and travelling, especially at night. A byproduct of fire is carbon dioxide, but saying that carbon dioxide is causing fires and heat is incorrect.
If this information is accurate, we should examine the mechanism of global warming and find better ways to reduce warming than taxing clean fossil fuels. Visit my website for more information at https://lovinThings.com/
