This Peatland Sensitivity Map to Climate Warming was prepared by Kettles and Tarnocai (1999) and superimposed on Google Earth Satellite image. It covers the exaple of permafrost melting in the previous post. It shows that this area is considered extremely sensitive to climate warming.

.

It is displayed as overlay in Google Earth for Manioba and a portion on Ontario in Canada.

In this area the southern permafrost line would move about 300 kms North.

Permafrost Sensitivity Map

In Canada peatlands cover about 12% of the land surface. (over 1.13 million km2). A large part of the carbon stored in peatlands could be released in the atmosphere as carbon dioxide and methane, further increasing climate warming.
