The negative effects of the global warming phenomenon and how to overcome the global warming




Global warming phenomenon

The global warming phenomenon

 

You should know that the global warming is caused by the greenhouse effect , And It is the continuous increase in the average temperature of the Earth's near - surface air .

 

You should know that the increase of the concentration of carbon dioxide gas leads to the increasing of the temperature .

 

You should know that the temperature of the planet Earth has been increasing since 1935 due to the increasing of the greenhouse gases .

 

The most important greenhouse gases 

 

Carbon dioxide gas  ( The ratio of carbon dioxide gas increased in the atmosphere to 0.038 % in 2005 after it was 0.031 % ) , Methane gas , Water vapour , Nitrous oxide , And Chlorofluorocarbon compounds .

 

What are the reasons of increasing carbon dioxide gas ratio in the atmosphere ?

Fossil fuel burning
Fossil fuel burning increases the ratio of carbon dioxide gas .

You should know that the increasing of carbon dioxide gas is due to the forests fires , The fossil fuel burning , And cutting the trees .

 

The greenhouse phenomenon

Greenhouse phenomenon
The increase of the ratio of greenhouse gases cause the increase of the planet Earth temperature .

You should know that the greenhouse effect is the trapping of the infrared radiation in the troposphere layer due to the increase of the ratio of the green house gases which causes the increase of the planet Earth temperature .

 

It is very important to know that when the concentration of the greenhouse gases increases in the atmosphere , the atmosphere , plays the role of the glass in the greenhouse , Where it permits the visible light , and the short - waved rays which produced from the Sun to pass .

The green house effect
The global warming phenomenon  .

You should know that the Earth and its components absorb these rays , and re - emit  the radiation back in the form of the infrared radiation which can not penetrate the atmosphere as it has a long wavelength .

 

So , It is kept trapped in the troposphere causing the rise of the planet Earth temperature  .

 

The global warming negative effects

 

From the most dangerous consequences  of the global warming is the melting of the snow of the two poles which increase the sea level in the seas and the oceans , It threats the coastal areas as they could drown , and causes the extinction of some polar animals like the polar bear and the seals .

Melting of snow of two poles
Global warming causes melting of ice and snow of both South and North Poles .

The global warming causes the severe climate changes  as the repeated occurrence of the tropical hurricanes such as hurricane Katrina in 2005 , The repeated occurrence of the forests fires , the drought waves  , and the destructive floods .

The drought waves
The global warming causes the repeated occurrence of the drought waves .

How to overcome  the global warming

The global warming
The indicators of the global warming in the world .

You should know that the bad destructive effects of the global warming made the representatives of  160 nations  in Kyoto ,  Japan in 1997 to sign a protocol called Kyoto Protocol which suggests to reduce the ratio of the bad emission  by cutting down the consumption of the fossil fuel , and to search for the environmental friendly alternative energy resources .
