THE CIRCUMPOLAR ARCTIC BOREAL FOREST

 

The greatest amount of forest carbon on Earth is not the Amazon. The Arctic-subarctic Boreal forest holds even more carbon, estimated at 22% of all carbon in the world's forested regions. The Boreal

or Taiga covers 16.6 million square kilometers / 6.41 million square miles.

 

The boreal forest grows on wetlands and permafrost (below the forest floor).

 

For a number of years now thje Boreal has been in decline (e.g. followed by Canadian forest service), after responding to more CO2 in the air by more forest greening. It is presumed to top global warming, which is very rapid in the subarctic regions.  

 

 

Back in 1998 a Greenpeace study aimed at protecting the boreal from industrial deforestation  recognized the Arctic boreal forest could become a catastrophic source of carbon due to effects of global warming and climate change.

 

2011 research found that the boreal forest and permafrost combined in a symbiotic partnership that maintained both enormous carbon sources.

 

There are normally fires affecting Boreal forest

 

A 2006 research paper  Climate-induced boreal forest change: Predictions versus current observations found that forest fires in the Boreal reported that fires were increasing all across the Boreal fro Siberia to Alaska and that in Alaska the forest was being damaged by increasing  bark beetle infestation- both associated with increased temperatures.

 

 

Forest fires emit mainly carbon dioxide but also some carbon  as methane. In the Boreal when fires occur in regions above permafrost the surface of the permafrost thaws and methane is released.

Much of the Arctic wetlands are in the boreal forest.
