This video highlights research conducted at Woods Hole on how heat absorbed by the ocean and changes of ocean chemistry from human activities could lead to a tipping point for marine life and ecosystems. Includes ice bath experiment that models the tipping point of Arctic sea ice.

This peer-reviewed educational video explains human-caused climate change including the greenhouse effect. The role that greenhouse gases play in absorbing and re-emitting longwave radiation is illustrated. Information on how scientists know that the observed global warming is a result of human activities that burn fossil fuels is concisely explained.

Here students use data from the NOAA carbon dioxide monitoring sites, such as Mauna Loa, to graph the Keeling Curve for themselves on large sheets of paper. Each group graphs one year, and the graphs are joined at the end to reveal the overall upward trend. The explanation describes the carbon cycle and how human activities are leading to the overall trend of rising carbon dioxide.
