Global Warming

Introduction

In recent decades , the Earth 's atmosphere and oceans has experienced an increased change in its average temperature , and scientists have termed it as `Global Warming (Avery , pp . 55-61 ) These predictions have some uncertainty due to the emissions of greenhouse gas volumes in the future , as well as the sensitivity to the different climate conditions around the world . The increased atmospheric concentration of the greenhouse gases is the main cause of the global warming around the

br world . Carbon dioxide is one of the main examples of these gases , by which surface and lower atmosphere warms up due to the increasing effect of the greenhouse . The burning of fossil fuels , agriculture , and land clearing are some of the activities that release the abovementioned greenhouse gases , and in the result , create this phenomenon of Global Warming

During the biological history of earth , significant changes are observed in climate of the planet . The planet has gone through different changes such as ice age , as well as , long-term periods of warm climate Historically , climate of the earth has been affected by some of the natural factors such as volcanic eruptions , as well as , by the amount of energy from sun . In addition , the Industrial Revolution and its associated human activities since late eighteenth century have also affected the composition of earth 's atmosphere (Stein , pp . 11-19 ) Our atmosphere has also been contributed with significant concentrations of trapped greenhouse gases due to the...
