The best FGIIP estimation is then fed back into the static model to generate numerous realizations considering the static uncertainties to produce...

... to determine the rates for the first 30 years of natural forest regrowth. A map showed more than 100-fold variation in rates across the globe and indicated that default rates from the Intergovernmental Panel on Climate Change may underestimate the rates by 32% on average and do not capture eightfold variation...
