Thermodynamic approach of the greenhouse effect and its impact through time
The Earth, with the passing of time, has been presenting great problems, of which a high percentage is the human being, because as the protagonist of inadequate behaviors he has led to serious effects being presented today. Punctually, covering the greenhouse effect and solar radiation as such, it is reached that its impact on Earth has triggered many environmental consequences, which can lead to the time, if their attention is not paid and the measures are takenrequired, the planet in a matter of years will be uninhabitable due to unbearable conditions for humans.
Influence of thermodynamics
Thermodynamics is essential to understand the effect studied in this project, because thanks to it it is possible to conceptualize and analyze what happens because of solar radiation and the emission of gases given the daily activities of human beings of human beings.
The atmosphere protects the earth, this is responsible for regulating the temperature, and is affected by human activities, so that gases, better known as “greenhouse gases” absorb a part of solar radiation (theHeat by radiation is 30% reflected to space, and the rest absorbs the atmosphere and the continents as such), which is not returned to space, as it should, but remains on the planet, giving rise to high temperaturesand strong climatic changes.
The name of this effect is related to the greenhouses, since the comparison was made with what happens in them, because in them the radiation does not pass directly thanks to the surface that protects them, but by convection the temperature is regulated;What happens with the atmosphere, but as in this one, certain types of gases are housed, there is an alteration in temperature, which leads to different harmful changes.
How is it understood from thermodynamics
Within this context, in the greenhouse effect, certain gases that are components of the atmosphere retain part of the energy of the planetary surface (soil). Likewise, in the effect addressed an energy transfer is presented in which the most notorious is the change in temperature. It is possible to identify the temperature variation making comparisons between the one that had been currently, and the current one, because as the greenhouse effect takes more strength, the temperature worldwide increases, giving rise to what is known as global warmingand the respective climate change that this entails.
Heat is the first principle of thermodynamics that refers to the fact that energy is transferred from one system to another due to the temperature difference between the two bodies. The Earth receives a small amount of the energy that is transmitted by the sun, but, this energy is received in the form of heat (more specifically by means of radiation).
In the same order of ideas, the heat by radiation occurs when the energy is transferred via electromagnetic waves, this occurs thanks to the emission of light, of which the atmosphere is entrusted to maintain the temperature of the planet so that it isAn optimal place for the survival of all living beings. In the case of the greenhouse effect, specifically sunlight, radiates and is partly absorbed by the gases mentioned in previous paragraphs.
It is worth mentioning that ultraviolet radiation is a concept of thermodynamics, which allows us to understand that electromagnetic energy that is emitted in very small waves that are not visible to the human eye and is known ultraviolet by its wavelength, which is between 100 and 200 nm. In the world, this ultraviolet radiation is coming from sunlight. This is related to the greenhouse effect, since the Earth receives energy from the sun in the form of electromagnetic radiation and this energy comes on the surface, but in the form of ultraviolet radiation.
It is essential to take into account, that greenhouse gases may be emitted through oceans and forests, since the first becomes a strong co₂ strong as well as the second, and all this caused by human activities. For example, in the case of deforestation, since the massive felling of trees causes the co₂ that they contain, be released into the atmosphere in incredible amounts.
There are carbonated rocks that merge into the ocean, and therefore, they release a lot of co₂. This gives way to the moment when temperatures have an increase;Which is alarming, because the ocean becomes a dangerous source of Co₂, by releasing all these gases that were to speak, retained, to the atmosphere.
In addition, the influence of thermodynamics in the change of state of the poles is notorious, since they are melting, which results in an increase in sea level, which triggers floods and more.
Other gases that capture radiation and travel to the atmosphere by convection, are those that occur in the industry (specifically from the production area), in the automotive transit, in the generation of electricity, in agriculture and livestock,etc.
It is necessary to mention the most frequently released gases to the atmosphere are: the direct (carbon dioxide (CO₂), methane (CH4), nitrous oxide (N2O), halogenated compounds, tropospheric ozone, water vapor) and indirect (Carbon (CO), volatile organic compounds other than methane (COVDM), sulfur oxides and particles, concentrations of greenhouse gases (GHG).
Effects on nature
It is important to be clear that the atmosphere is a thin layer that is composed of gases and that surrounds the entire planet Earth. These gases are of great importance because they are basically fundamental for the good life of the planet.
The greenhouse effect and its increase in land seriously affects the environment, since a consequence is that, due to some gases that are emitted, the temperature of the earth increases and this in the long term can be lethal for the life of many beingsalive, including us. The seas can grow in an exaggerated way due to the accumulation of gases in the atmosphere and this leads to that the islands could disappear due to floods.
The glaciers are thick ice masses that originate on the earth’s surface and could be very affected by this effect, since, when temperatures are increased, ice will be melted easily.
GHGs are different dissolved gases that are part of the air and these vary depending on the layer in which they are and, therefore, their temperature varies. These gases retain part of the heat of the earth and if these gases increase the temperature, the ecosystems will be seriously affected to the point that may disappear due to the toxic damage that will be reflected.
In the world there are different water sources that are large water currents (whether underground or on the surface). These can be rivers, wells, springs, etc. With the increase in temperature, these water sources will be affected and can dry, leading to a disappearance of them from the entire planet Earth. The vital component of the world is water, and if this consequence will happen, a great negative impact towards agriculture and livestock will be seen, because both depend on this component, the animals would die and the plants would wither, leading to a total disappearanceof fauna and flora.
