Read about Global Warming in your textbook in chapter 45 and conduct additional research if needed to discuss the following topic.  This video provided by National Geographic on Global Warming (Links to an external site.) should help you to understand the topic.

Many scientists view global warming as the most important environmental issue facing the Earth’s ecosystems. Many models developed by scientists have predicted a warming of the Earth that is correlated with increased carbon dioxide emissions which are associated with the combustion of fossil fuels. However, over the past 10 years, the rate that the Earth is warming has outpaced some of the models. Scientists have realized that “feedback loops,” not considered in some of their models, are likely responsible for the unprecedented warming. A feedback loop is a system in which the output of a system impacts its own production. In a positive feedback loop, the output increases the production.

In a negative feedback loop, the output decreases the production.  Briefly discuss and explain what global warming is and how this phenomenon could impact our planet as well as why we should be concerned about global warming.  Hint:  Climate change/weather patterns/ balanced ecosystems etc.  In addition, highlight measures that can be taken to avoid the dangers of global warming.  Be sure to address each part of the discussion
