What scientific evidence exists that Earth's climate is changing? What's the difference between climate change and climate variability? How does a changing climate affect people and the natural environment? What can we do to lessen and adapt to the impacts of these changes? This collection of videos presents experts' lectures and discussions on these topics in a series of public forums hosted in 2011 by NOAA and the Osher Lifelong Learning Institute at George Mason University.
