Climate controls any ecosystem. Since the Industrial Revolution, there is a change in the climate through many actions of human beings, which is also affecting the ecosystem indirectly. 

The following activities of human beings are considered as important factors responsible for the change of climate:

1. Deforestation: Mankind is excessively exploiting the forests for its convenience and benefits, which has resulted in irregularity in rainfall and increased temperature. 

2. Industrialisation: Toxic gases emitted from indiustrial units not only pollute the air, but due to their impact, the ozone layer starts to deplete. The ozone layer prevents the ultraviolet and infrared rays coming from the sun to reach the earth and absorbs them before reaching the surface. As a result of the toxic gases, there has been an unprecedented increase in the incidence of skin and respiratory diseases in the world. 

3. The invention of nuclear power: The most devastating scientific invention of humans is the discovery of nuclear bombs, due to which the climate is affected by the underground or oceanic explosions. After the Pokhran blast, abnormal rainfall in the Barmer area is an example of this. Whatever is being done by scientists in the name of development, all that is directly impacting the climate and indirectly impacting the ecological system.

From December 6 to 17, 2004, a climate change meeting held in Buenos Aires did not reach any consensus on the changes in the weather and determining the reasons behind this and the efforts needed to control them. The reason for this is the uncompromising attitude of developed countries such as the United States, the Soviet Union, Italy, etc. Not only that, countries such as Saudi Arabia, Oman and Qatar are also opposed to curbing carbon emissions, because doing so could cause a crisis for their economy.

Today, the behavior of the weather in every country of the world is unusual. It appears as if there is no definite season of rain. There is no fixed place for the snowstorm, because snow fall has taken place in Dubai. There is no definite season for blooming of flowers, when the summer season will stat and what temperature will be reached, it is not possible to determine. The main reason for this unusual behavior of weather is the increase in global temperature.

The Inter – governmental Manual on Climate Change has warned about global warming, that if it is not stopped, there will be a large number of storms and floods, temperature will increase and the number of people killed by Loo and hot storms will also increase. The only way to reduce it is to reduce the emission of greenhouse gases by 50% to 70% from the 1990 level.

In June 2004, the Government of India released the first National Communication Report on climate change. In which for the first time according to this report, an increase of 0.4 degree Celsius in the average temperature in the last 100 years has resulted in an increase in rainfall of 10 – 12% in the west, north – western part of the country and northern Andhra Pradesh.
