Climate Change

The burning issue of the 21st century is one of the prominent factors for erupting destruction in the earth’s environment and is more vital to the human lifestyle; it is “Climate Change”.

The earth’s atmosphere is composed of different types of greenhouse gases (carbon dioxide (CO2) , water vapour (H2O), methane (CH4), nitrous oxide (NO2), and ozone (O3), etc)these gases trap the suns heat and keep the earth warm. They create a warm blanket around the earth which is known as green house effect. If these gases were not there, the earth’s temperature would be – 18 degree centigrade.
However, if the concentration of greenhouse gases (GHG) increase in the atmosphere, it will trap more heat and the earth will get warmer and warmer disturbing all the natural balance leading to global warming.

It has been estimated that the cause of the climate change are due to the increase in the human made chemicals like chlorofluorocarbons (CFCs), hydro fluorocarbons (HFCs) as well as in the increase of gases like carbon dioxide, sulphur dioxide, sulphur oxide, methane and ozone. These gases act like a barrier which does not allow the heat to radiate to the space but reflects it back to the earth atmosphere.

As the earth’s environment is affected, its components are definitely the victim or the prime source for getting wiped out and eradicated. Similarly the natural biological diversity which includes the wildlife habitation and flora and fauna for instance Royal Bengal Tiger, one horned rhinoceros, red panda, herbal plants, ayurvedic plants, and herbs are in danger of getting extinct.

Among all the North Pole, South Pole and Third pole {mountainous region} like Indo Gigantic plains, Tibetan plateau, Rocky Mountains of North America, and European Alps are one of the perilous components. Glaciers are retreating rapidly. The snowlines are melting in rapid manner and the streams are rushing in rapid manner causing the high risk for GLOF {Glacier Lake Outburst Flood}. Simultaneously the ocean and sea level are mounting due to uprising temperature making the life of aquatic animal hazardous.

So hence every year various international seminar, conference and convection are held in various part of the world. A similar international conference was held in Nepal by ICIMOD {International Center for Integrated Mountain Development} which includes fifty scientists from Asia, Europe and North America. Such discussions are done aiming to reduce the climate change by raising public awareness, impact management issue and its strains by establishing policy map in most vulnerable areas around the globe.
