The greenhouse effect and climate change Shubham Sarpal University of Texas at San Antonio Research Question: How does human activities cause rise in greenhouse gasses emissions? Answer/Thesis: While there are many gasses that human activities emit directly into the atmosphere, some major gasses which are causing harm in the atmosphere and resulting in the increased greenhouse effect are: • Carbon dioxide: It is originated by burning of fossil fuels such as coal, oil and gas, though deforestation is also a very significant contributor. • Methane: It is due to agriculture (especially livestock and rice fields), fossil fuel extraction and the decay of organic waste in landfill sites. • Nitrous oxide: sources include agriculture (especially nitrogen-fertilized soils and livestock waste) and industrial processes. • Fluorinated gases: This gas is generated due to industrial processes. As a result of this, the United States had suffered record-breaking floods along the Mississippi River on 9th September 2011, high snowstorms from the Midwest to the Northeast even massive wildfires in the West and South, deadly tornadoes in the South and Midwest. The reasons behind the change in the extreme weather is due to global warming which is caused by increase in greenhouse gasses emissions as the scientists say. INTRODUCTION Global warming is caused due to the presence of the gasses in the atmosphere, mainly carbon dioxide, methane, chlorofluorocarbons and nitrogen oxide
