Idealized deforestation experiment. 20 million square km forest area (covered by trees) is converted to natural unmanaged grassland over a period of 50 years with a linear rate of 400000 km2/yr followed by 30 years of constant forest cover. Run for 80 year

Idealized deforestation experiment. 20 million square km forest area (covered by trees) is converted to natural unmanaged grassland over a period of 50 years with a linear rate of 400000 km2/yr followed by 30 years of constant forest cover. Run for 80 years. Simulations should be branched from an 1850 control simulation (piControl) at least 80 years prior to the end of the piControl simulation so that deforest-globe and piControl can be directly compared. All pre-industrial forcings including CO2 concentration and land-use maps and land management should be maintained as in the piControl. Deforestation should be restricted to the top 30% of land grid cells in terms of their area of tree cover. Effectively this concentrates deforestation in the tropical rainforest and boreal forest regions. (CMIP6 Experiment).
