Monitoring permafrost degradation rates due to climate change : developing a practical GIS-based method
Peatlands in the Alberta boreal forest are predicted to experience early and severe climate change impacts through permafrost degradation (melting). Permafrost loss and the subsequent release of greenhouse gases are predicted to have significant global climate change implications. This study provide...
