Modeling Earth's climate future

Rising carbon dioxide levels in the atmosphere are driving changes in Earth’s climate. But scientists are still trying to answer important questions about how carbon dioxide emissions get absorbed by the land and the ocean — and how this could change in the future. NASA Goddard Space Flight Center’s Lesley Ott talks about how NASA’s high-powered computer models are giving us a better understanding of carbon’s role in Earth’s changing climate. http://www.nasa.gov/carbonclimate | NASA Sea Level
