22 of 24 postsDon’t Blame Gases For Green House Effect

Don’t Blame Gases For Green House Effect Dr. Dev Bahadur Dongol Friday September 25, 2009 Source : THE RISING NEPAL Upon looking scientifically into the nature of gases as fluids, it is not possible for any gas in our immediate atmosphere to form a ‘green house’. Therefore, it is quite logical to conclude that it is not the ‘green house effect’ of any gas that is causing global warming and climate change.6. Our atmosphere is perfect transparent after vacuum so reflection phenomenon is not possible. If gases of our atmosphere are reflective we should not be able to see objects through nor earth would be visible from space.

Then what is causing global warming and climate change? We know there are many agents that are heating our Earth and our immediate surroundings, the troposphere. They are mainly the sun and our burning activities on the surface of the Earth.
Heat released as hot air is cooled down naturally by the convection method of heat transmission. But man has disturbed the process used by nature to cool the surface of the Earth, land and water that absorb so much of the heat from the sun.
There are at least three natural mechanisms that help to cool down the surface of the Earth. They are air current, rain cycle and hurricanes or cyclones or tornadoes.
The convection method of heat transmission continues all the time non-stop. Human activities have no control over it. The heated surface of the Earth heats the air near by. Heated air molecules go up as they become lighter and release heat when they reach the cold front high up. Cold molecules come down as they become heavier. This convection current is working day and night. If it had not been so, our surroundings would have been already hot enough to boil water. So gases are actually helping to cool off the heated surface of the Earth through the convection method.
Obviously nature has a more effective mechanism, i.e., the rain cycle. Water has the highest heat absorbing capacity, much higher than that of air or any gas, so the rain cycle is more effective than air current in cooling down the Earth surface. But the rain pattern is changing and our surroundings are becoming hotter.
After winning the fight against ‘global warming and climate change’, we would want a colder surrounding, a regular rain pattern as before, plenty of water for a rich vegetation, easy irrigation and drinking water, more ice on the poles and mountains, constant recharging of ground water and eventually a lower sea level rise.
All these factors are related to one phenomenon - the rain cycle. Thus, reviving the ‘rain cycle’ near to the old comfortable weather pattern would be a satisfactory solution in winning the fight against ‘global warming’ and ‘climate change’. Unfortunately we have disrupted the rain cycle badly through urbanisation and deforestation due to population growth.
The rain cycle needs a lot of evaporated water. As water vapour molecules go up, they release the heat absorbed from the surface of the Earth. They then become cold and condense as water droplets and come down as rain. But then we have blocked the evaporation process of water from the surface of the Earth by covering it with houses, roads and pavements. Deforestation has caused the land area to become drier and drier.
Recharging of ground water is minimised as water used by the people is also drained and added to the sea. Much of the rainwater is also drained to the sea. Recharging of the soil through rainwater is also reduced significantly. Evaporation of water from the surface of the Earth is, thus, reduced. For water to evaporate, it calls for the soil to be always wet and exposed to the air so that water evaporates as soon as the sun heats the soil.
Scattering of water on all available surface of the earth, including the vast tracts of the deserts, is necessary so that the rain cycle is not disrupted. Rains occur only in a short period of time of the year nowadays because we have blocked the evaporation system of nature. Enhancing evaporation of water from a much wider surface of the Earth will naturally lower its temperature and boost rains, which will further lower the temperature of the Earth surface.
Thirdly, when the rain cycle is disrupted and the Earth’s surface becomes very hot, we tend to face hurricanes, which bring torrential rains and floods. This system of cooling by nature may be considered as emergency measures. This is the way we are having rains these days, but this also may not last very long.
No more worries
Thus, boosting evaporation of water from the surface of the Earth as widely as possible will set us free from the worry of ‘global warming’ and ‘climate change’ for good. Rains will add snow on the mountains. Recharging of the ground with water will store immense quantities of water back again. Both the phenomena will eventually lower the sea level.
