Which of the following is the biggest source of uncertainty in our projections of how much the global climate will warm by 2100? 1) Model spread (associated with differences in how GCMs represent the climate system) 2) Scenario spread (associated with differences in assumed anthropogenic climate forcing scenarios) 3) Internal variability (associated with natural processes, like ENSO) 4) Downscaling spread (associated with uncertainties in dynamical and statistical methods)1)
