1900 Air Pollution

Examine this graph from FRONTLINE/NOVA: "What's Up with the Weather?" Web site to see dramatic increases in three greenhouse gases over the last two hundred years.

20-Year Map of Global Rainfall

This visualization from NASA shows global rainfall patterns over a 22-year span. It incorporates data from a combination of remote-sensing and ground-based sources.

Alaska Native Pilots

In this video adapted from Storyknife Productions, Alaska Native pilots share how they use traditional knowledge to read the landscape and predict the weather.

Alaska Native Ways of Knowing

In this media-rich lesson, students prepare classroom science fair projects that demonstrate the application of traditional knowledge to a scientific topic.

Arctic Haze

In this video segment adapted from KUAC, find out why the horizon in Alaska is sometimes shrouded in pollution and what it means for climate change in the Arctic.

Arctic Sea Ice Satellite Observations

In this interactive activity produced for Teachers' Domain, learn how Arctic sea ice has changed over the past 25 years in terms of maximum winter extent, concentration, and the timing of breakup each spring.

Avalanche Town

The impact of natural disasters is made vivid in this video segment adapted from NOVA. A small town in Iceland, prepared for recurrent avalanches, is devastated when one takes a new and damaging path.
