This video features changes in the land, sea, and animals that are being observed by the residents of Sachs Harbour, Northwest Territories, Canada â many of whom hunt, trap, and fishâbecause of their long-standing and intimate connection with their ecosystem. Scientists interview the residents and record their observations in order to deepen our understanding of climate change in the polar region. Background essay and discussion questions are included.

This static image from NOAA's Pacific Marine Environmental Laboratory Carbon Program offers a visually compelling and scientifically sound image of the sea water carbonate chemistry process that leads to ocean acidification and impedes calcification.

This video discusses observations of two key warning signs of global change effects on the Southern Ocean: changes in Antarctic bottom water and ocean acidification.

This video provides a comprehensive introduction to the role of coral reefs, the physiology of corals, and the impacts of both ocean warming and acidification on coral survival. It highlights experts from the Bermuda Institute of Ocean Sciences and the University of Miami.

This video describes the effect of a warming climate on the tundra biome and specifically the impacts of changing climate on the Rocky Mountain Pika, a small rodent that struggles with summer heat.

A short video on the causes of ocean acidification and its effects on marine ecosystems.

This video provides background information and teaching tips about the history and relevance of phenology and seasonal observations of plants and animals within the context of rural Wisconsin.

This video illustrates conditions under which two infectious diseases - cholera and dengue fever - flourish, and how climate change is likely to exacerbate those conditions.

This video is the second of three short videos showcasing the dramatic changes in Alaska's marine ecosystems. The video highlights the marine mammals and birds and how they depend on Arctic sea ice, as well as questions about how these animals will cope in the face of climate change.

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.
