Within the Discussion Board area, write 4–6 pages that respond to the following:
The greenhouse effect and greenhouse gasses have increased as a result of human activities (anthropogenic), primarily since the Industrial Revolution. These gasses led 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, Climate Change 2007: Synthesis Report, stating the following: “Global GHC emissions due to human activities have grown since pre-industrial times, with an increase of 70% between 1970 and 2004” (2007). 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 Warm Period than they were in the 1990s.
For this Discussion Board, you are to discuss the questions below about global warming:
· What are greenhouse gases?
o List 3 greenhouse gases. What are the sources of these?
