Learn how scientists have pieced together a continuous 800,000-year record of atmospheric carbon dioxide levels and ocean temperatures in these videos from NOVA: Decoding the Weather Machine. Use this resource to review the difference between inference and observation and to consider the relationships between carbon dioxide, Earth's temperature, and climate change.
