Global warming predicted to hasten carbon release from peat bogs
Date:11/6/2008

bogs in northern Manitoba to temperature increases of 4 degrees Celsius, or 7.2 degrees Fahrenheit, a gain that is at the conservative end of estimates for the next 100 years. Their modeling looked specifically at water table dynamics, since peat bogs' stability is grounded in their cold, waterlogged nature.

"Previous modeling has assumed that decomposition in peat bogs is like that in a conventional soil," Moorcroft says. "Ours is the first simulation to take a realistic look at the interaction between the dynamics of the water table, peat temperatures, and peat accumulation."

Moorcroft plans to continue the research by expanding his group's analysis of peat bogs and water tables to global scales.
