The ecological consequence of frequent fires is permanent vegetation change to reduced diversity and productivity.

Permafrost. Ground frozen for millennia. An enormous deposit of organic carbon forming a thick, peat-like under-layer.
Forced to warm at an unprecedented rate through the massive burning of heat-trapping gasses by human beings, this layer is now rapidly thawing, providing an amazing source of heat and fuel for wildfire ignition.
Joe Romm over at Climate Progress has long called this region ‘Permamelt.’ But, with a doubling of the number of wildfires for the high Arctic and an extension of the permafrost fire season into early April this year, we may well consider this to be a zone of now, near permanent, burning — Permaburn.

For Khakassia, Russia the story this week has been one of unprecedented fire disaster.
