Global Warming: How Humans are Affecting Our Planet

This NASA video segment discusses the role people play in causing global warming. People burn more and more fossil fuels everyday, increasing Earth's temperature. This keeps more of the sun's heat and energy within Earth's atmosphere causing temperatures on Earth to rise. This video explains the effect warmer temperatures are playing on Earth and what people can do to reduce these effects. Dr. James Hansen from NASA's Goddard Space Flight Center provides examples of ways that people can minimize some of the damage caused by global warming.
