Tides of Change

Coastal ecologist Dr. Steve Fradkin is a National Park Service scientist who spends his days in the intertidal zone of Olympic National Park. There, a spectacular diversity of plants and animals interact to form a living, breathing ecosystem that is an especially sensitive indicator of environmental health. Climate change is beginning to take its toll on this fragile ecosystem, but as long as Steve gets a good cup of coffee, he'll be out there monitoring the changes and figuring out what we as humans can do to help.

Glaciers are sensitive indicators of climate change. In this video we meet Dr. Jon Riedel, lead glaciologist at North Cascades National Park. Jon shows how he monitors glaciers and explains his reasons for doing so.
