Global Warming; Although the contribution of water vapor, carbon dioxide, methane, ozone etc. in the atmosphere is very low, but they are important gases.
Similarly, ozone gas absorbs ultraviolet rays coming from the sun and protects human life from its harmful effects.
Similarly, these gases also maintain the ideal temperature of the earth (average temperature 15 ° C).

Carbon dioxide, in equilibrium, is essential for plant life on the earth plane,
Global warming meaning
Global warming
Green House Effect
  • These gases allow the short wave and radiation coming from the sun to reach the earth plane but effectively absorb the external long wave radiation coming out from the earth plane and reflect them back to the earth. This increases the temperature of the lower layer of the atmosphere attached to the ground, which is called the 'Green House Effect'.
  • In fact, the Green House is a glass room made of glass.
  • Large glass houses are made for growing vegetables and flowers in cold countries.
  • In this glass houses, the small wave radiation coming from the sun easily enters, but after converting to heat, this heat does not come out of the glass house in the form of long waves, and under these conditions the temperature of the glass house Increases in

 Global warming meaning   -

  • Our atmosphere also works like a natural glass house.
  • But in the past, due to urbanization, increasing industrial development, obtaining energy from fossil fuels and destruction of forests, the concentration of these green houses has increased, as a result of which the temperature of the world is being continuously marked.
  • Before the Industrial Revolution, the amount of CO2 in the atmosphere was 280 PPmv which has now increased to 365 PPmv. It is estimated that in the last fifty years, the air dryness of the earth, south-central Eurasia and North America has increased.


 Causes of global warming 

1 Power Generation Centers -Large quantities of coal and mineral oil are burnt in power generation centers, due to which the CO2 gas released from it reaches the atmosphere and causes global warming

2. Indiscriminate harvesting of forests also promotes CO2 uptake because trees and plants have the ability to absorb carbon dioxide inside them.

  • Per minute in the world, according to a report by UNEP. 38 acres of forests are being wiped out, due to which the average temperature has increased by 1 ° C due to which the amount of CO2 in the atmosphere is increasing.
  • Also, the amount of CO2 increases in the atmosphere even when there is a fire in the forests.


3. The density of CO2, nitrogen, oxide, methane, ozone, chloro-fluor carbon in the atmosphere is also increasing through human activities in which industrialization is the main.
  • The main reason is fossil fuel combustion, the rate of combustion is increasing at the rate of 4% per annum and due to this
  • The amount of CO2 gas in the atmosphere is increasing at the rate of 2% per year.
  • It is estimated that since the Industrial Revolution, the Earth's average temperature (ISC) has increased by 0.4%.
4. Transport is one of the main reasons for increasing CO2 and other gases in the atmosphere.
  • With automatic vehicles powered by coal, diesel and petroleum, CO2 is released into the atmosphere in large quantities.

5. Domestic use of fossil fuels is also increasing the amount of CO2 in the atmosphere.


Effects of global warming

1. Climate change -

  • So far, due to global warming, the temperature of the Earth has increased by 1 ° C, and if the rate of growth and industrial pace remains the same, then the temperature of the Earth can be increased from 1.5C to 5.4 ° C.
  • By increasing the temperature of the earth, the direction of winds will be changed, which also changes the order of rainfall.
  • In the regions situated at high latitudes, the thrust of rainfall will be high, with drought at some places and flood and cyclone conditions will start to occur at some places.

2. Effect on production of food grains

  • Due to the increase in the temperature of the earth, while there will be an increase in the number of plant diseases and pests, on the other hand, weeds and unnecessary plant glut will affect the crop production badly. Increase in 1 ° C temperature will reduce rice production in South East Asia by 5%.
  • This may pose a serious risk of a worldwide food crisis.
  • Dr. Scindia Rosenjing has stated in a study that world warming will definitely have a negative impact on India,
  • Where food production will decrease while food production will increase in countries like Canada, Australia, USA and former Soviet Union.

      3. Effect on sea level

      • As a result of global warming due to the increase in greenhouse gases, the seas will also heat up, which will be responsible for the increase in its water level.
      • Due to the warming on Earth, melting of frozen ice on Arctic and Antarctica fumes and melting of glaciers of high mountains is expected to increase sea level by half a meter.
      • Due to this, many lower parts of the earth (areas up to 60 km from the beach) will be submerged.
      • A flood-like situation will arise on these beaches, and the possibility of some cities being completely submerged can create a terrible situation.

      Global Warming Solutions

      1. The first primary measure is to stop the destruction of forests.Forest area can be increased by cutting trees with new trees and intensive plantation.
      2. It is important to find an alternative source of chloro-fluoro-carbons (CFC).
      3. By eliminating the energy technology being obtained from the burning of organic fuel and coal, the discovery of new technologies of energy production can prevent the production of greenhouse gases, and stabilize the Earth's heating process. is.
      4. The international agreement for the emission reduction of greenhouse gases, which became effective on 16 February 2005 with the consent of 141 countries, should be strictly implemented.

      The treaty states that industrialized countries should reduce greenhouse gases emissions by 5.2% by 2010 compared to 1990 levels.
      Each member country, with its own pollution level, will set a limit for the reduction of greenhouse gases emissions.
      • Although the US and Australia have rejected this treaty which emits thirty percent of the total greenhouse gases.
      • This treaty took place in the city of Kyoto, Japan in 1997 and hence it is called the Kyoto Treaty.
