4. “When cars, power companies, and other industries burn oil, coal, and gasoline, they release carbon dioxide and other gases into the atmosphere. These gases accumulate in the atmosphere, creating a heat-trapping blanket, and causing the earth to warm. This makes the world hotter and disrupts weather patterns and the environment in several different ways. This effect is called climate change.” What is Climate Change? 31 March 2012 – Power to Prepare – Tucson, AZ
