THE CHANGING OF EARTHS NATURAL GREENHOUSE


Human activities are changing the natural greenhouse. Over the last century the burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2. Also responsible for higher levels of CO2 is the clearing of land for agriculture, industry.




CO2 STICKS AROUND


CO2 remains in the atmosphere longer than the other major heat-trapping gases emitted as a result of human activities. It takes about a decade for methane (CH4) emissions to leave the atmosphere (it converts into CO2) and about a century for nitrous oxide (N2O).


After a pulse of CO2 is emitted into the atmosphere, 40% will remain in the atmosphere for 100 years and 20% will reside for 1000 years, while the final 10% will take 10,000 years to turn over. This literally means that the heat-trapping emissions we release today from our cars and power plants are setting the climate our children and grandchildren will inherit.

The surface temperature on our planet ought to be on average approximately 15 degrees Celsius.

A higher content of atmospheric greenhouse gases results in an increased absorption and reabsorbing cycle.

Gases in the atmosphere such as carbon dioxide do what the roof of a greenhouse does. Trapping solar heat  that is responsible for our weather as we know it.

Inversion layers are blankets of air trapping various sorts of air pollutants. Natural ventilation by the convection mechanism is not possible.

More greenhouses gases results more absorbed heat in the atmosphere.
