Thousand years of climate change reconstructed from chironomid
subfossils preserved in varved lake Silvaplana, Engadine, Switzerland.
Quaternary Science Reviews, Volume 29, Issues 15-16, July 2010, Pages 1940-1949 doi:10.1016/j.quascirev.2010.04.018
Fossil chironomids (non-biting midges) from varved Lake Silvaplana,
Switzerland, were used to reconstruct climate (mean July air temperatures)
during the last millennium. At the beginning of the record, corresponding
to the last part of the "Medieval Climate Anomaly" (MCA) (here the period
between ca 1032 and 1262 AD), the chironomid-inferred mean July air
temperatures were 1 °C warmer (p < 0.01) than the climate reference period
(1961-1990). The "Little Ice Age" seems to have been separated into three
phases: significantly colder (-1.1 °C in average, p< 0.001) temperatures
were inferred between ca 1262 and 1481 AD, between ca 1514 and 1718 AD
(-1.2 °C in average, p< 0.001) and between ca 1734 and 1782 AD (-0.6 °C
in average, p< 0.1). Although the average temperature changes inferred by
chironomids were within the error of prediction (1.5 °C) of the chironomid-
temperature inference model used for reconstruction, the pattern of
temperature changes corresponds well with records of the past millennium
in Switzerland, in Europe and in the Northern Hemisphere. The average
inferred July temperatures between ca 1900 and 2001 AD were significantly
warmer (p < 0.05) than the climate reference period (1961-1990) by 1 °C
which is in agreement with the instrumental data. The inferred July
temperatures were in the same range as the inferred temperatures during
the last part of the MCA suggesting that during the 20th century,
at Lake Silvaplana, the chironomid-inferred temperatures do not
exceed the natural climate variability of the past millennium.
STUDY NOTES: Chironomid-inferred mean July temperature from Lake Silvaplana,
Switzerland for the last 1000 years. Data are presented with
3-year, 10-year, 20-year, and 50-year triangular filters,
as plotted in Figure 6a of Larocque-Tobler et al. 2010.
