Global warming is considered one of the greatest environmental threats of the 21st century. While scientists debated the causes and effects of global warming in the 1980s and early 1990s, a consensus was reached in the late 1990s that global warming is a serious concern. This document assigns a group project to create a presentation investigating why global warming should be a concern and to include an introduction, explanation of causes and effects in developed and developing countries, evaluation of different viewpoints, solutions, and a conclusion stating the group's opinions.
