Ice and Fire
Listen to climate change in Alaska through place-based narrative.
Ice and Fire is a podcast that uses audio storytelling to share cryosphere change as the global climate warms. The cryosphere is all of Earth's frozen surface water including frozen freshwater lakes, glaciers, permafrost and sea ice -- frozen saltwater.
It only takes a small temperature increase for water to melt or thaw from solid into liquid form, yet a cascade of impacts result when we lose ice to fastly flowing liquid.
Season one emphasizes the significance of glacier melt, and connects listeners to distant glaciers rapidly responding to anthropogenic climate change through dialogue with researchers, traditional knowledge-bearers, and by sharing audio of ice-melt in real time.
Season two, available now, is all about permafrost thaw.

woolly mammoth bones
In episode four we learn about carbon stored within woolly mammoth bones and ancient plants, long held within the walls of the the Cold Regions Research and Engineering Laboratory's permafrost tunnel located near Fairbanks, Alaska.
Forty thousand years ago permafrost trapped microbes, rock, and sediment when water froze around it all. The ground ice also captured ancient plants and mammal bones, making carbon stores visually apparent as permafrost oxidizes or thaws. These processes also have an odor.
topics and purpose: What all is in permafrost and emerges as it thaws?
terms defined: the Pleistocene Ice Age, organic matter
notes: Learn more about the Army Corps of Engineers' Permafrost Tunnel Research Facility in Fox, Alaska here. A previous version of this episode suggested that the tunnel was excavated to act as a protective underground enclave in the event of foreign occupation during the Cold War; this has been revised for accuracy. It was actually excavated in the 1960s as an experiment to test whether the tunnel could act as a bunker for military weapons systems.
