Greenhouse gases and the Theory of Global Warming

2-3 paragraphs (original work)

The Greenhouse effect and greenhouse gases have increased as a result of human activities, (anthropogenic) primarily since the Industrial Revolution. These gases lead scientists to the Theory of Global Warming.

As an environmentalist, you are very interested in the Theory of Global Warming and climate change. The United Nations has established The Intergovernmental Panel on Climate Change (IPCC) that published the AR4 Synthesis Report. "Global GHC emissions due to human activities have grown since pre-industrial times, with an increase of 70% between 1970 and 2004." Other scientists say that Global Warming does not exist and support the idea that climate fluctuations are natural changes that have happened before in historical weather patterns. Evidence from all over the world indicates that the earth was hotter 1,000 years ago than it is today. Research shows that temperatures were higher in what is known as the Medieval Warming period than they were in the 1990s. You are to discuss the questions below about Global Warming:

What are Greenhouse gases? List 3 greenhouse gases. What are the sources of these?
_____________________________________________________________________________
Greenhouse gases are chemical compounds in the earth's atmosphere that absorb infrared radiation and trap it as heat (Rodhe, 1990). This considerably warms our atmosphere. The three major greenhouse gases that are cited in literature are carbon dioxide, methane, and nitrous oxides (EPA, 2012). However, water vapor is also an important green house gas. Carbon dioxide is naturally regulated and formed during the carbon cycle, as it is used in plant photosynthesis and created during respiration . However, anthropogenic sources of carbon dioxide are more apparent and originate from fossil fuel emission and land use change. This includes forest clearings and automobile emissions. Methane is produced by landfills, coal mines, oil and gas operations, and agriculture (EPA, 2012). Lastly, nitrous oxides are emitted from burning fossil fuels and through specific fertilizers and industrial processes (EPA, 2012).
