Green House Effect By Gases Is Impossible

Man has disrupted the rain cycle by urbanization and deforestation. The rain cycle is the second main cooling system of nature. So the warming of our surrounding, what we call the global warming, SEA LEVEL RISE AND OTHER RELATED PHENOMENA are due to the disturbances of the rain cycle caused by man. By understanding the fluid nature of the gases and methods of heat transmission, the green house effect by gases is impossible. Therefore the so-called global warming is not the result of green house effect of the gases. Thus climate change is not the result of global warming but other way round; the global warming is the result of climate change. The correction is possible and probably get the result within two years by war footed global level undertakings. By the efforts for reviving rain cycle will reduce the global temperature, recharge ground water, enrich vegetation, distribute water throughout the year and worldwide, make drinking water available, add snow on the poles and mountains, and thus eventually reduce sea level also.
Methods of heat transmission - Heat travels from higher temperature to lower temperature front. Heat is transmitted by three methods. They are radiation, conduction and convection.
Radiation- it is a method when heat energy jumps or travel in all directions without any medium from the source and is absorbed by any object that is on the way. It is like throwing many objects and others catch some of them. This is the method how we get heat from the Sun.
Conduction – this is the process when heat is passed on from one molecule to another adjacent molecule. This happens when we heat a solid substance that is a good conductor of heat e.g. a metal. It is like passing an object from one end to another end by standing many people in a queue.
Convection- this process of heat transmission happens when fluids, gases and liquids, are heated. They have freely moving molecules, so when heated they move in the upward direction. They release heat when they reach cold front. They come down again when they become cold. This process of moving molecules up and down goes on repeatedly while the fluids are being heated. This process is something like we picking up goods from the shops and deliver them at homes repeatedly.
Green House - It is a space covered by glass. Heat entered is trapped inside. Air inside also cannot move in and out of the glass walls. So temperature inside is kept much warmer than outside the glass walls. Heat is transmitted to outside atmosphere by only conduction method when temperature outside is less than inside of the green house.

Green House Effect Considering Fluid Properties Of Gases - The up and down moving air molecules as convection current cannot make a shield as solid glass makes wall of a green house. Air we breathe in and out is a homogenous mixture. There is no separate layer for separate gas. Had the air been layered according to gases, our immediate layer of gas would be carbon dioxide not oxygen. Carbon dioxide is the heaviest gas in the air. We need oxygen to breathe and be alive.

So by looking scientifically into the nature of gases as fluids it is not possible for any gas of 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.
Causes - Then what is causing the global warming and climate change? Obviously we need answer to this question and solve the terrifying problem. 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. Heated objects remain hot without cooling system. Heat released as hot air is cooled down naturally by convection method of heat transmission. But man has disturbed main and effective process used by the nature for cooling the surface of the Earth, land and water that absorb so much of heat from the Sun. So let us see the natural mechanisms that help to cool down the Earth surface.

Natural Cooling Mechanisms - There are at least 3 (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 Air Current – the third method of heat transmission, the convection method, is going on all the time non-stop. Human activities have no control over it. 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 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 surrounding would have been already hot enough, if not more, to boil water. So gases are actually helping to cool off the heated surface of the Earth by convection method.

RAIN CYCLE - Obviously nature has another more effective mechanism as well, the rain cycle. Water has highest heat absorbing capacity, much higher than that of air or any gas, so rain cycle is more effective than air current to cool down Earth surface. We know it is cool when it rains. The rain cycle also works as convection current. We know rain pattern is changing and our surroundings are becoming hotter year-by-year.

After winning the fight against ‘global warming and climate change’ we want 1. Colder surrounding, 2.regular rain pattern as in the old comfortable weather, 3. Convenient water resources thus rich vegetation, easy irrigation and drinking water, 4 add ice on poles and mountains, 5. Recharge ground water and 6. Eventually lower sea level rise. simple logic, take water back to the places where it came from.

All those factors are related to only one phenomenon- the rain cycle. Thus reviving ‘rain cycle’ in a regular pattern near to old comfortable weather is the one and only solution to win the fight against the ‘global warming’ and ‘climate change’. Unfortunately we have disrupted the rain cycle too much by urbanization and deforestation because of the population growth. The ‘rain cycle needs lot of evaporation of water. As water vapor molecules go up, release heat they have absorbed from the surface of the Earth, become cold and condense as water droplets and come down as rain. Unfortunately, we have too much blocked evaporation process of water from the surface of the Earth by covering it with houses, roads, pavements etc. Deforestation caused land area drier and drier. Recharging of ground water is minimized as water used by people is also drained and added to sea. Much of rainwater is also drained to the sea. Recharging soil by rainwater is also reduced significantly. Evaporation of water from the surface of the Earth is reduced too much. Evaporation of water needs soils always wet and exposed to air so that it is evaporated as soon as the Sun heats the soil. Scattering of water on almost all the surface of the earth including vast area of deserts is necessary, like before the urbanization era, for enough evaporation so that rain cycle is not disrupted. Rain pattern is concentrated only in a short period of time of the year nowadays because we have blocked the evaporation system of nature. Enhancement of evaporation of water from the much wider surface of the Earth will naturally lower its temperature and boost rains, which will further lower the temperature of the Earth surface. Scattering of water on the surface of water must be made a culture of human beings using water resources as much as possible, not sparing even deserts. This is not a difficult task for the present capabilities of mankind. We have now infrastructures as well as technology to fulfill this task easily. Main source can be discharged water from the hydropower installations, which discharge immense quantity (I do not think that any body has calculated) of water every second. We can spread water by draining it from any higher places to lower land. This draining system of water can also be used for producing clean energy, hydroelectricity by installing hydropower stations in series along the same one water-supplying pipe. Installed turbines do not decrease power of running water through out the pipe while water is flowing, because of the fluid properties of water and the nature of the Gravitational Force of the Earth. The Earth is blessed with unlimited hydropower.

Explaining –“Turbines Do Not Decrease The Power Of The Running Water”

Turbines are designed to discharge the same quantity of water as is flowing through the water-supplying pipe. Because of the fluid properties of water and the nature of the gravitational force of the Earth, the running water throughout the given pipe has water pressure, rate of discharged water and the velocity of water etc constant. So the power available is also uniform throughout the pipe while water is running. Therefore, a turbine installed at any point between the intake and the outlet points of the pipe does not affect its efficiency or decrease its efficiency. Because the turbines are designed to discharge the same quantity of water as is discharged throughout the pipe, the turbine makes no changes in the rate of discharged water. So the other factors like velocity, pressure of water in the pipe are also not changed. Since there is no difference in those factors before and after the installation of a turbine means a number of more turbines can be installed in series along the same water-supplying pipe without decreasing their efficiency, as they make no changes in the available power of running water. Given the topography or landscape is favorable multiple turbines can be installed in between the intake and outlet of the same water supplying pipe without decreasing their efficiency. They do not make any reduction of power of the running water through out the given pipe while water is running. They are designed to discharge the same quantity of water as is running through the given pipe. So the same (existing as well) infrastructure of water supplying-pipe can run many more turbines in series making hydroelectricity far cheaper, easier, and faster than at present. This system of installation would not require hydro dams at all. Only run off type will do. So the intake point for water can be at the source where we can tap very clean water at the highest possible point as well as adding power of running water to the possible maximum level.

Hurricanes - Thirdly, when the rain cycle is disrupted and Earth’s surface becomes very hot, as nowadays we have to face hurricanes, which bring torrential rains and floods. This system of cooling by nature may be considered as the emergency measures to keep earth’s surface cool. This is the way we are having rains nowadays, but this also may not be for very long.

Conclusion - Thus boosting of evaporation of water from the surface of the Earth as widely as possible, from every inch of the earth surface, will set us free from the worry of the ‘global warming’ and ‘climate change’ for good. Rains will add snow on the mountains. Recharging of ground with water will store immense quantity of water back again. Both the phenomena will eventually lower the sea level. We should make spreading of water on the surface of the Earth as our instinct culture.
