This animation describes how citizen observations can document the impact of climate change on plants and animals. It introduces the topic of phenology and data collection, the impact of climate change on phenology, and how individuals can become citizen scientists.

This series of visualizations show the annual Arctic sea ice minimum from 1979 to 2010. The decrease in Arctic sea ice over time is shown in an animation and a graph plotted simultaneously, but can be parsed so that the change in sea ice area can be shown without the graph.

This interactive visualization from the NASA Earth Observatory website compares Arctic sea ice minimum extent from 1984 to that of 2012.

This video looks at the impact of changing climate on animal habitats around the world, showing how different creatures are responding to changing temperatures and precipitation patterns.

This video features residents of Shishmaref, Alaska, plus environmental journalist Elizabeth Kolbert and scientist John Holdren, exploring the human impacts of global climate change. The roles of teachers, scientists, policymakers, and concerned citizens in mitigating the changes are highlighted.

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

In this activity about climate change on the Antarctic Peninsula, learners investigate environmental changes in the living and nonliving resources of Antarctic peninsula and the impact of these changes on AdÃlie penguin communities. The activity stresses the importance of evidence in the formulation of scientific explanations.

This short video clip summarizes NOAA's annual State of the Climate Report for 2009. It presents a comprehensive summary of Earth's climate in 2009 and establishes the last decade as the warmest on record. Reduced extent of Arctic sea ice, glacier volume, and snow cover reflect the effects of rising global temperature.

This video presents predictions and solutions for range shifts (wildlife corridors) by an iconic species of North American wilderness: the wolverine.

Coral Reefs in Hot Water is a short video displaying computerized data collected on the number of reefs impacted by coral bleaching around the world.
