In 2013 the Pew Research Center conducted a poll of more than 37,000 people in 39 countries and found that more than half believe climate change is a major threat. Through a narrative-driven pro/con format—supported by relevant facts, quotes, anecdotes, and full-color illustrations—this title examines issues related to climate change. Topics include: Is Climate Change Caused by Human Activity? Has the Extent of Climate Change Been Overstated? Will Climate Change be Harmful to Society? and Should Society Try to Reduce Climate Change?
