Global Warning – What is the cause?

In 1920 the world population was less than 2 billion people, today there are about 8 billion people.  In the last 100 years, we have quadrupled our population.

Everyone of these 8 billion have an internal furnace generating approximately 98.6 degrees of heat. 

These people have homes where grass and forests used to grow. 

These homes use heat to cook food, and the heat finds its way outdoors.

These homes use heat in the winter and cooling in the summer.  Homes don’t retain heat or cooling very well and the equipment used for heating and cooling generate more heat.

These homes have roofs which collect heat from the sun and reflects it when the sun goes down.

When it’s 90 degrees outside, it is liable to be 125 in your attic.  Your attic is probably vented to the outside.

Homes are connected by streets, most of the time it’s black asphalt which absorbs the suns heat and then reflects it when the sun goes down.  

When the temperature is 75 degrees, asphalt can heat up to 125 degrees.

All hard surfaces, including asphalt, will absorb heat. This causes not only the surface temperature to rise, but also causes the ambient temperature to rise.

Automobiles and other means of transportation create a lot of heat when the engine is running.  It is estimated that there are 1.4 billion motor vehicles in the world.  Now add the 350,000 trains and 106,000 airplane flights per day.  There are currently more than 50,000 merchant ships operating in the oceans and an estimated 30 million recreational boats in the world.  (Could this be part of the reason the ocean level is rising?)

On a sunny 70-degree day, it only takes about a half hour for the temperature inside a parked car to reach 104 degrees!  After one hour, it can reach 113 degrees. When it's 90 degrees outside, it could reach an incredible 138 degrees.  

To answer the question, I believe global warming is a result of the growth of earth’s population and it’s going to get a lot worse.

The world gains over 100 million new citizens every year.  In the year 2122, we should have over 20 billion people.  How are we going to provide food, water, utilities, medicine and homes for 20 billion people?  What effect will 20 billion people have on the temperature of our planet?
