<p> Global Warming Presentation</p><p>The presentation should be submitted to Google Classroom and take between 3-5 minutes to complete. </p><p>Background Section - Explain the overall process of global warming. o How does it work? o What are the major greenhouse gases and where do they come from? Include both natural and manmade sources.</p><p>- Explain historical temperature changes o How many ice ages have we had? When did they occur? o Explain the “Medieval warming period” and the “little ice age” o Describe how global temperature, carbon dioxide, and methane levels have changed over the course of human history. Explain reasons for these changes.</p><p>- Explain some of the consequences that are occurring right now as a result of global warming. Focus on one concept that you feel is of interest to you. o Coral reef bleaching o Increased droughts o Longer and stronger hurricanes o Sea level rising o Ocean temperature increasing o Ocean acidification</p><p>Opinion Section </p><p>- What effects have humans had on the atmosphere? How does this relate to temperature change and climate? </p><p>- How fast is the global temperature rising? Is this part of a normal cycle or due to human influences?</p><p>- What other factors, besides the greenhouse effect, could account for some of the climate and temperature variations we’ve seen? Example: Increased solar activity</p><p>Objective Articles To Read for a Background on Global Warming</p><p>Earth 2100: The Effects of Greenhouse Gases Excellent article about global warming, its causes and effects. http://www.pbs.org/newshour/indepth_coverage/science/globalwarming/map.html</p><p>Wikipedia Good summary of the global warming controversy.
