A Contribution to Earth Warming: The Human Factor (Part 1)

Earth Warming

Chapter 1 – Atmospheric Warming

The “Volume” of Air above the  Earth’s surface is a constant volume. Its upper Limit is its height above the Earth as constrained by gravity. Its lower limit is the surface of the Earth above the land and seas.

This volume (V) of atmospheric air is warming up. Air, being a gas, is subjected to the Universal Gas Law, which is – Its pressure (P) multiplied by its volume (V) and divided by its temperature (T) in its appropriate units, is a constant (K). This applies to any specific mass of gas.

Applied to the whole of our atmosphere,

PV/T = K

So if the temperature of the atmosphere rises, then its PV must also rise. Since V is constant, the pressure in our atmosphere will rise whenever its temperature rises.

Within any air mass in the atmosphere, the interplay of its pressure, volume, and temperature, together with the Earth’s spin and its surface profile, causes the air movements. So if our atmospheric temperature rises, the pressure will also rise. Winds will be stronger and faster. This strength and speed of air movements will continue to increase if the atmospheric temperature continues to increase. Wind speeds will keep on increasing as the atmospheric air continues to warm. This will result in more and more violent weather.

Chapter 2 – Greater Precipitation

There is basically two ways where water vapor rises into the atmosphere. One is by heat and the other is by wind.

The same amount of heat from the Sun will cause more water to be evaporated from the Earth’s surface (river, lakes and seas) if the water temperature is higher. Our air temperature is rising, so is the temperature of our seas. And because of this, there is more water being evaporated every day. More evaporation means more rain.


Our air temperature is higher. This means our winds are now stronger or faster. Faster winds means more water vapor will be picked up by these winds. Eventually, this means heavier rainfalls or greater precipitation.

More water vapor in the atmosphere also means more snow in the winter. The heat sink in the upper atmosphere has an “infinite” capacity to cool down any water vapor that rises up to that level.

So we will have heavier and heavier rainfalls and heavier snow falls.


When there is more water vapor in the air, there will more energy released when these vapor becomes rain. The energy released is the heat of condensation and results in lightning. When the heat of condensation is released, it is accompanied by a sudden volume collapse. The volume change is from the vapor stage (gas) to a liquid (water) stage. These will cause thunder when the

collapse space causes air masses to collide through the vacuum created. The world area will become turbulent when there is a continual volume collapse as more rain is formed from its vapor stage.

More water vapor will ultimately means heavier turbulence – and stronger tornadoes and hurricanes.

Chapter 3 – Rising Ocean Level

As ocean and other bodies of water gets warmer, its volume increases. Melting ice will also increase its volume. When ocean level rises, some beachside land will get submerged. The other effect of rising sea level is the volume of atmospheric air will be reduced. The upper air boundary remains unchanged because there is no change in gravity. The lower boundary rises as water levels rise.

In accordance with the Gas Law as applied to the atmosphere, reducing volume has the same effect of rising temperature. It will cause greater pressure changes and making air movements stronger. This results in stronger weather.

    The gas law is for a gas in a confined space, the atmosphere is in a contained space. In whether terminology a high cell is a cell of high pressure, vice versa for a low. A high is often associated with high temperature due to adiabatic compression.
