Climate Projections from Marcell
Experimental chambers located in the boreal forest at Marcell, MN have revealed what could happen to global boreal forests and peatlands as the climate continues to warm. Similar studies in Canadian and Alaskan regions are confirming the results found at Marcell. Global warming is causing: 1) peatlands to dry out, leading to more wildfires (e.g. Greenwood fire) and changes in boreal plant communities; and 2) permafrost to melt, flooding boreal forests and local communities. Both of these changes are resulting in huge net increases of carbon emissions as boreal forests /peatlands and permafrost areas change from carbon sinks to carbon sources. The vegetation in boreal forests/peatlands will change from conifers and mosses to shrubs and deciduous trees. Currently, in Alaska, frequent fires and permafrost melting are favoring regeneration of deciduous trees over conifers and surface waters are "browning" due to the release of colored organic acids from the thawing peat. Thus, we are seeing the beginning of whole ecosystem changes from global warming.
