PROBLEMS
Earth’s surface is so thin that we can change the concentration of compounds which are composed of the atmosphere. Particularly, concentration of carbon dioxide increased surprisingly. These kinds of green house gases make the layer of atmosphere thicker and emission of infrared radiative energy become decreased. Thus, the temperature of atmosphere and the ocean reached to dangerous figure.
First : Thickening Earth’s layer by global warming
There had been seven ice ages and warming for last 650000 years and the concentration of carbon dioxide hasn’t exceeded over 300ppm. However, recently, carbon dioxide concentration goes far beyond 300ppm. This is why the overall increasing carbon graph observed by Rodger Level shows increase-decrease shape.
Numerical value of carbon dioxide in 2005 was twice of that when it had been highest in the past. For now, we expect the figure of carbon dioxide in 2055 as about 1000ppm showing vertical increasing tendency.
Second : Severely high concentration of carbon dioxide
Graph of the amount of carbon dioxyde
As almost all of the Earth’s surface exist above equator, when northern hemisphere tilts to sun in spring and summer, vegetation bloom and absorb carbon dioxide. Therefore, the worldwide amount of carbon dioxide decreases. However, in autumn and winter, northern hemisphere is far from the sun.
Thus, the carbon dioxide that vegetation absorbed re-emits and that amount of concentration increases.
Increasing of carbon dioxide lower pH by increasing of carbonic acid in the ocean and acidizing the ocean water gradually.
Extreme increasing of northern hemisphere’s temperature and concentration of carbon dioxide through glacier study by Thompson.
Blue shape represents predictions only with natural variable. The Green one, the prediction with assumption that human being affect to global warming. The Red line represents the Real value.
Increasing of ocean temperature encourages speed of storms which become faster and induces saturated humidity to be higher. Additionally, increasing of saturated humidity contributes to the apparition of severe rains or snowfall and huge scale of flood can be occurred frequently.
Many places in Africa have now severe droughts.
There is a real and important acceleration of desertification ( reference in UNCCD )
Earth's precipitation changes
Third : Extreme effect of ice melting on Earth’s temperature
When Earth’s temperature increases of 1° Celsius degree, northern hemisphere gets 12° Celsius degrees increased temperature which results in an accelerated ice melting.

Fourth : Acceleration of global warming by increasing population and economic growth
Population of 1700's was a billion and in 2050, the population forecast will be grow-up to about 9.1 billion.
For now, the number of people all around the world become a direct factor which affects the Earth.
This population's needs will grow up and people will require so much food, energy and water that it could cause many damages to the Earth ressources and viability.
