Climate of the last millennium at the southern pole of the North Atlantic Oscillation: an inner-shelf sediment record of flooding and upwelling

SST determinations based on the alkenone index UK37 indicate annual upwelling in tensity as the determinant factor for SST variability confirming the Tagus results (Abrantes et al. 2009)

Long-term summer temperature reconstruction inferred from tree-ring records from the Eastern Carpathians

Using AD 1901_1950 as the calibration period the Pearson's correlation coefficient between grid data and reconstruction is 0.34 and for verification is 0.47

2500 years of European climate variability and human susceptibility

This composite record includes living trees historical timber and subfossil wood and correlates at 0.72 to 0.92 with interannual to multidecadal variations in instrumental June-to-August (JJA) temperature (1864_2003)

A palaeotemperature record for the Finnish Lakeland based on microdensitometric variations in tree rings

Calibrating and verifying the MXD chronologies against the instrumental temperature data showed a promising opportunity to reconstruct warm-season (May through September) temperature variability

Thousand years of climate change reconstructed from chironomid subfossils preserved in varved lake Silvaplana, Engadine, Switzerland

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 1C 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.
