Write a note on global warming and it's consequences.
Answers
Global warming is a a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, CFC's, and other pollutants.
It's consequences are:
Rise of sea level is probably the most talked incident about outcome of global warming. Mountain glaciers feed rivers and supply fresh water to villages downstream. Without these glaciers, villagers will have no water supply. Changes in climate will cause animals to alter their desired habitat. Some estimates predict the extinction of millions of species. Warmer waters mean move violent storms and hurricanes. Heat waves will help spread disease.
ANSWER:-
Global warming is a gradual increase in the temperature of the earth surface and atmosphere all around the world. It is caused due to the greenhouse effect of increased level of green house gases such as carbon dioxide, CFCs, etc. There are various types of pollutants also which involved in increasing the atmospheric temperature of the earth. Increasing use of fossil fuels by the people and deforestation is increasing carbon dioxide emissions which trap heat and cause greenhouse effect.
Water vapor is also a significant greenhouse gas which is not directly produced by humankind but involve in global warming hugely. A slight increase in the level of CO2 causes marked increase in earth temperature. Green house gases absorb and re-radiate infrared radiations which ultimately cause green house effect. Because of deforestation, CO2 is not absorbed well and remain in the atmosphere for long time and trap heat.
