Summary;
We all know the explanation of heat in the atmosphere explained with a greenhouse effect, which consists of the retention of infrared radiation emitted by the atoms of the earth by certain gases in the air, this work explains the heat because of the ionization of oxygen by the ultraviolet radiation of the sun, which consists of oxygen (21% of the air) absorbing the entire band of uv radiation from the sun, this ionizes the air, when the air is ionized it becomes a conductor of electricity, increasing its kinetic energy (temperature), its increase means that there will be a greater transfer of heat energy from the air when it comes into contact with everything that is on the surface of the planet.

Introduction;

The heat on the planet is explained by the greenhouse effect, which consists of certain gases in the atmosphere absorbing infrared emitted by the surface of the earth, originating the heat in the air, this work shows the heat on the planet more specifically in the air as the consequence of the ionization of oxygen molecules from the air, by ultraviolet radiation from the sun.

Scientific theory:

The greenhouse effect is a process in which thermal radiation emitted by the planetary surface is absorbed by atmospheric greenhouse gases (GHGs) and radiated in all directions. As part of this radiation is returned to the Earth's surface and lower atmosphere, resulting in an increase in the average surface temperature compared to what would be in the absence of GHGs. (1)

Heat, is thermal energy transferred from a hotter system to a cooler system that are in contact. (2)

Temperature is a measure of the average kinetic energy of the atoms or molecules in the system.

We can calculate the heat released or absorbed using the specific heat capacity C, end the mass of the substance m, and the change in temperature ΔT, end text in the equation:

q=m×C×ΔT. (3)

The composition of the Earth's atmosphere.

The atmosphere of the planet is made up of 78% of nitrogen which is an inert gas that usually does not react with other substances. 21% oxygen, which is a highly reactive gas. 9% argon, and 01 percent of other gases.

Almost the whole of the air (95%) has less than 30 km high, being more than 75% in the troposphere. The air form in the troposphere a mixture of gases homogeneous to the point that their behavior is equivalent to that which would have if it were composed of a single gas.

• Nitrogen: constitutes 78% of the volume of air. It is composed of molecules that have two nitrogen atoms, so that your formula is n2. It is an inert gas, i.e. that usually does not react with other substances.

• Oxygen: represents the 21% of the volume of air. It is formed by molecules of two atoms of oxygen and its formula is O2. It is a gas very reactive and most of the living beings need to live.

• Argon: contributes in 0.9% of the volume of air. It is a noble gas that does not react with any substance.

• Carbon dioxide: it is composed of molecules of a carbon atom and two oxygen atoms, so that your formula is CO2. Represents the 0.03 per cent of the volume of air (4)

Oxygen

Is a chemical element of atomic number 8 and represented by the symbol O, under normal pressure and temperature conditions, oxygen is a colorless and odorless gas with O2 molecular formula, in which two oxygen atoms are linked to the electronics of Triple-State configuration. This link has a two-link order and is generally simplified in the descriptions as a double link or as a combination of a two-electron link and two three-electron links.  (5)

Development,

Global warming can be explained by the ionization of oxygen molecules from the air, which constitutes 21% of it, which consists of oxygen molecules absorbing ultraviolet light from the sun, which ionizes these molecules, turning air into a good conductor of electricity, this electricity increases the kinetic velocity of all molecules in the air, increasing the average kinetic energy of the air, which is the physical definition of temperature, so there will be a greater transfer of caloric energy, when air molecules come into contact with everything on the surface of the earth.

Conclusion;

We can conclude that the heat on the planet is the product of the ionization of oxygen molecules (21% of the air), by the ultraviolet radiation of the sun, turning the atmosphere into an electrical conductor, increasing its kinetic energy, therefore heat, Not by infrared radiation emitted by the earth's surface, which is retained by greenhouse gases, which make up 0.04% of the air.
