Global warming means a gradual increase in the Earth's average lower atmosphere due to emissions and build up of greenhouse gases . Global warming is when the earth heats up and the temperature rises. It happens when greenhouse gases such as carbon dioxide, water vapor, nitrous oxide, and methane trap heat and light from the sun in the earth’s atmosphere, which increases the temperature. Most greenhouse gases are released by the burning of fossil fuels for heating, cooking, electrical appliances, transportation, and manufacturing, but they are also released as a result of the natural decomposition of organic materials, wildfires, deforestation, and land-clearing activities. The diffusion of these gases results in the spread of various epidemics,
I believe that the repercussions of the soaring temperature are serious and irreversible. Global warming is a problem that could have devastating long term consequences. It causes sea levels to rise everywhere, permanently flooding many low lying parts of the earth. Many geographical areas may experience reduction in crop yield due to drier and hotter condition. In particular, global warming will cause the extinction of many under water species. Also, the higher temperatures contribute to the melting of glaciers and expansion of ocean water as it heats up, both of which cause sea level to rise. Higher sea levels erode beaches, increase storm surges, lead to a loss of wetlands, and can compromise freshwater supplies by introducing saltwater. Global warming will cause destruction of whole forests due to environmental changes and forest fires, and an increase in extreme weather such as tsunamis. It will also lead to increased human illnesses and deaths. Climate change also is likely to increase the number of species that are listed as threatened or endangered.
There are innumerable reasons for global warming. Burning of fossil fuels is the one of the primary causes for global warming. It
