Scientific Community Debates on Causes and Consequences of Global Warming: Review

Abstract

Global warming is a most burning topic gained the attention of many social thinkers such as scientists, policy makers, environmentalists, researchers and student worldwide. It is the increase of the average temperature on the Earth. The root cause for the increase of the temperature is global warming. As the Earth is getting warmer, disasters like hurricanes, disease and injury of heat waves, droughts, storms and floods are getting more frequent. Over the last 100 years, the average air temperature near the Earth’s surface has risen by a little less than 10C. The causes and consequences of global warming on the Earth`s environment have been reviewed in the present study. The controversy between scientists on the causes of global warming may be natural or may be caused by human interference. The natural causes were atmospheric carbon dioxide (CO2), Volcanic Eruptions, the dynamic system of the Earth, Sun, and Cosmos. Human activities have been emitting extra greenhouse gases, which were mostly resulted from burning of fossil fuels (like coal, oil and gas). Urbanization and associated human activities like industrialization and use of cars, deforestations and land use changes and etc. have been identified as human-induced causes of global warming. About 97% of climate experts believed that human-activities are the major causes of global warming. Generally, global warming is affecting rainfall, shrinking of the ice sheets, increasing average temperature, affecting plants and animals, rising sea level and shifting seasons.
