Chironomids can be reliable proxies for Holocene temperatures. A comment on Velle et al., 2010
Brooks, SJ, Axford, Y, Heiri, O, Langdon, PG and Larocque-Tobler, I (2012) Chironomids can be reliable proxies for Holocene temperatures. A comment on Velle et al., 2010. The Holocene (doi:10.1177/0959683612449757). (In Press).
Velle et al. (The Holocene 20 (2010) 989–1002) discussed discrepancies between Scandinavian Holocene chironomid-inferred temperature estimates,
which they attribute to the response of chironomids to environmental variables other than temperature and to taxonomic shortcomings. They suggest
ways in which the reliability of chironomid-based paleotemperature reconstructions could be improved by taking into account ecological complexity.
While we agree with many of their recommendations, based on the results of other work, we think their paper is unnecessarily pessimistic regarding
the ability of existing chironomid-based temperature inference models to provide reliable estimates of past temperature. We offer a critique of the main
points discussed by Velle et al. (2010) and provide evidence that chironomid-based temperature inference models can reliably reconstruct mean July air
temperature in the Lateglacial and Holocene over millennial and centennial timescales.
