Green House Effect

     Let us have a look over the Greenhouse Effect also. According to our Scientists Greenhouse gases are gases in an atmosphere that absorb and emit radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect. The main greenhouse gases in the Earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Greenhouse gases greatly affect the temperature of the Earth. The greenhouse effect is caused by an atmosphere containing gases that absorb and emit infrared radiation. Greenhouse gases trap heat within the surface-troposphere system, causing heating at the surface of the planet or moon. This mechanism is fundamentally different from that of an actual greenhouse, since the Earth's surface reflects about 28% of incoming sunlight, in the absence of the greenhouse effect the planet's mean temperature would be far lower - about -18 or -19 °C instead of the much higher current mean temperature, about 14 °C, that is true.

     Now, the conclusive study on Global Warming says that there is a presence of water vapor, carbon dioxide, methane, nitrous oxide, and ozone in the atmosphere, which absorbs the infrared radiations emitted by the earth surface. Due to human activities, the water vapor is decreasing on the basis of the above illustrations and the carbon dioxide and other gases are also increasing due to the loss of vegetation and Flue Gas emissions from fossil fuel combustion. The micro analysis reveals that there are still very serious questions still unanswered; those are: –

– During the process of “Green House Effect” what percentage of heat is trapped by the gases within the surface-troposphere system; causing the Global Warming?

– Why the quantity of heat transferred into the atmosphere – by the law of convection; the heat transferred towards the colder reservoirs – by the law of conduction; in the absence of humidity in the upper layer of the Earth Surface; when there is a Depletion of Groundwater, is not estimated?

– If infrared radiations (reflected/indirect heat) emitted by the gases were responsible for the heating of the Earth’s Surface i.e. “The Greenhouse Effect or Global Warming”. If around 30% of solar radiation is absorbed by the gases could raise the temperature of the earth surface, then what about the calculations for the heat generated by more than 60–70% of direct radiation exposed on the Earth Surface in the absence of humidity or higher level groundwater or evaporation of water from the soil and vegetation? Why it was also not calculated in the context of Global Warming with the decrease in vegetation land areas due to Depletion of Groundwater throughout the world? What may be the consequences of radiations absorbs by the Earth Surface in the absence of the humidity?

– According to the Scientists the GW-Factor (Global Warming) flows from the atmosphere to the Earth Surface, which is responsible for the warming of the planet earth surface; why only emissions were blamed?

Figure-8

     All the past predictions for the Global Warming before the above “GW Prediction” were being concentrated over only a 30% percentage of reflection of the sunlight, absorbed by the gases; the infrared radiations were responsible for the Greenhouse Effect/Global Warming, whereas the analysis of the remaining 70% of the sunlight absorbed by the Earth’s Surface was completely ignored along with the study of Groundwater Depletion and we failed to arrest the root causes, those are actually responsible for the Global Warming.  There is a very serious correlation between the Global Warming and the Depletion of the Groundwater and we still have to understand it more deeply.
