Korhola

To further test the hypothesis that temperature increases drove the system, Korhola et al. [71] analyzed additional sedimentary proxy indicators from Lake Saanajärvi.

Sorvari and Korhola [70] studied the recent (~150 years) environmental history of Lake Saanajärvi, located in the barren tundra at an elevation of 679 m in the northwestern part of Finnish Lapland.

Korhola et al. 2000 published the first diatom-based quantitative climate record covering the entire Holocene for northwestern Finnish Lapland.

However, the temporal resolution in the Korhola et al. study was rather coarse 50–70 yr, for which reason detection of any shorter-term climate patterns was not possible.

Especially for the last ca. 1000 yr, the record seemed to mimic well the known climatic events, such as the Medieval Warm Period (MWP), the Little Ice Age (LIA), and the post-industrial climate warming (Korhola et al., 2000).

There was virtually no difference in the general trend of the reconstruction obtained here and the one published in Korhola et al. 2000, bearing in mind that the present study is based on a completely new core and contains new diatom counts.

The Korhola proxy is used in Moberg et al 2005, where it contributes to the warmish MWP in Moberg.

The Korhola Chironomids differ considerably from Seppa and Birks Chironomids & from most of the others but it does show a MWP.

Most of the quantitative reconstructions from Finnish Lapland (Figure 4) show warmer than at present at c. 1000 years ago (Korhola et al., 2000, 2002; Seppa and Birks, 2001, 2002, Seppa et al., 2002).

Moberg et al. [2005] use the July temperature reconstruction of Korhola et al. [2000] using Lake Tsoulbmajavri diatoms as one of 11 low-frequency proxies, as shown in Figure 4 of Korohla et al. reproduced below.
