“So why is so much carbon dioxide in the atmosphere a bad thing? Experts say it prevents Earth’s natural cooling cycle from working — meaning heat is trapped near the surface, causing global temperatures to rise.”

USA Today reports, “The recent temperature rise cannot be explained by natural factors, scientists report. In the past 20 years, the world’s temperature has risen about two-thirds of a degree Fahrenheit, the National Oceanic and Atmospheric Administration said.”
