Several Yukon communities are built on permafrost. In the context of climate change, that’s something of a problem. CBC News reports on a six-year research project that has produced hazard maps of seven Yukon communities; the maps evaluate the risk to future development from permafrost melting, flooding and ground instability.

Mapping Arctic Permafrost


NASA Earth Observatory: “The map above, based on data provided by the National Snow and Ice Data Center, shows the extent of Arctic permafrost. Any rock or soil remaining at or below 0 degrees Celsius (32 degrees Fahrenheit) for two or more years is considered permafrost.” The map differentiates between continuous, discontinuous, sporadic and isolated permafrost.
