To make sense of our present biodiversity crises, the modern rate of
species extinctions is commonly compared to a benchmark, or “background,”
rate derived from the fossil record. These estimates are critical for
bounding the scale of modern diversity loss, but have yet to account for
the fundamental structure of extinction rates through time. Namely, a
substantial fraction of extinctions within the fossil record occur within
relatively short-lived extinction pulses, and not during intervals
characterized by background rates of extinction. Accordingly, it is more
appropriate to compare the modern event to these pulses than to the
long-term average rate. Unfortunately, neither the duration of extinction
pulses in the geological record nor the ultimate magnitude of the
extinction pulse today is resolved, making assessments of their relative
sizes difficult. In addition, the common metric used to compare current
and past extinction rates does not correct for large differences in
observation duration. Here we propose a new predictive metric that may be
used to ascertain the ultimate extent of the ongoing extinction threat,
building on the observation that extinction magnitude in the marine fossil
record is correlated to the magnitude of sedimentary turnover. Thus, we
propose that the ultimate number of species destined for extinction today
can be predicted by way of a quantitative appraisal of humanity’s
modification of ecosystems as recorded in sediments –that is, by comparing
our future rock record with that of the past. The ubiquity of habitat
disruption worldwide suggests that a profound mass extinction debt exists
today, but one that might yet be averted by preserving and restoring
ecosystems and their geological traces.
Data associated with “Towards Quantifying the Mass Extinction Debt of the
Anthropocene” by C. Spalding & P. M. Hull. In Section 3.1 of the
main text, we introduced our data, which was drawn from the paleobiology
database (PBDB), the compilation of Barnosky et al. (2011), the IUCN Red
List (as of 2019) and the publication of Heim & Peters (2011).
