Abstract
In this paper, we describe the development and application of a new spatially
explicit weathering scheme within the University of Victoria Earth System
Climate Model (UVic ESCM). We integrated a dataset of modern-day lithology
with a number of previously devised parameterizations for weathering
dependency on temperature, primary productivity, and runoff. We tested the
model with simulations of future carbon cycle perturbations, comparing a
number of emission scenarios and model versions with each other and with
zero-dimensional equivalents of each experiment. Overall, we found that our
two-dimensional weathering model versions were more efficient in restoring
the carbon cycle to its pre-industrial state following the pulse emissions
than their zero-dimensional counterparts; however, in either case the effect
of this weathering negative feedback on the global carbon cycle was small on
timescales of less than 1000 years. According to model results, the largest
contribution to future changes in weathering rates came from the expansion of
tropical and mid-latitude vegetation in grid cells dominated by
weathering-vulnerable rock types, whereas changes in temperature and river
runoff had a more modest direct effect. Our results also confirmed that
silicate weathering is the only mechanism that can lead to a full recovery of
the carbon cycle to pre-industrial levels on multimillennial timescales.
