The warming and cooling of our blue planet is a natural phenomenon and is a result of subtle shifts in its orbit as the atmosphere or surface changed and also because of the variance in
the Sun’s energy which is responsible for climate change But, the past
century has witnessed a cataclysm in this change solely because of
“global warming.” Global warming is the bizarrely hasty swell in Earth’s
average surface temperature principally due to the greenhouse gases
released because of the reckless usage and consumption of fossil fuels.
The global average surface temperature has risen exponentially, and the
rate of temperature increase has nearly doubled in the last 50 years. Earth’s temperature rise begins with the Sun. More or less 30 percent of the incoming sunlight is reflected back and the remaining 70 percent is absorbed by the land and ocean, and by the atmosphere. The absorbed solar energy is responsible for heating up the earth. This absorption and radiation of heat by the atmosphere is the natural greenhouse effect that is essential and beneficial for life on Earth. If there were no greenhouse effect, the Earth’s average surface temperature would have been very chilly and uncomfortable. Due to careless human behavior and actions the concentration of greenhouse gases has risen immensely; the chief reasons being deforestation and burning of fossil fuels. The atmosphere today contains more greenhouse gas molecules and hence all the climate change issues are occurring all over the world. We should pledge to Go Green & work for Earth care to keep our planet from degrading any further. http://www.gogreenindia.co.in/thegoodearth/
