Global warming class 7

Some of this energy is radiated back into the atmosphere. The gases present in the atmosphere for example ozone, methane, carbon dioxide, water vapor and chlorofluorocarbons are called greenhouse gases, they absorb some heat thereby restricting the heat to escape our atmosphere. These gases add to the heating of the atmosphere and result in global warming. In places where the temperature is low, we use glass covered areas known as a greenhouse to grow flowers, fruits, and vegetables.

Along with it, deforestation due to industrial or economic purposes and the excess burning of fossil fuels like natural gas, oil, and coal, has increased the concentration of atmospheric carbon dioxide from ppmv part per million by volume to about ppmv since These are some of the primary reasons for which the heat gets trapped in the atmosphere thus causing global warming.

Consequences of Global warming Warmer climate: The rise of sea level: Due to global warming, the glaciers and ice sheets of Greenland and Atlantic will melt which will add water to the sea level, thus causing many disasters like Tsunami.

A rise in sea level will also have an economic impact especially on the low-lying coastal areas and islands causing unavoidable soil erosion. According to multiple experiments, with the high concentration of CO2 in the atmosphere, the growth of crops is twice than the normal growth.
