Corrigendum by Tadeusz Niedźwiedź (Chapter 3)
Corrigendum and explanations concerning BACCII Chapter 3 “The Historical Time Frame (Past 1000 years)”, pages 57 and 64.
Text on page 57:
“Recent investigations of Fennoscandia by Ljungqvist(2010) showed that the MWP occurred between 800 and 1300. At that time, warm-season (May–September) temperatures exceeded the contemporary warming of the end of twentieth century by about +0.5 °C.”
must be corrected as follows (corrections are in red):
“Recent investigations of temperature variability in the extratropical Northern Hemisphere by Ljungqvist (2010a) showed that the MWP occurred between 800 and 1300. At that time in Scandinavia north of 60° N (Ljungqvist 2010b), warm-season (May–September) temperatures exceeded the contemporary warming of the end of twentieth century by about +0.5 °C.”
Also in the References on page 64:

must be corrected and supplemented by the second paper of Ljungqvist (2010b):

Additional comment and explanation
The information that during “warm-season (May–September) temperatures exceeded the contemporary warming of the end of twentieth century by about +0.5 °C” was taken from the curves of a temperature reconstruction in the second paper of FC Ljungqvist (2010b), presented on page 7 on Fig. 3. The level of temperature deviation is about +0.4°C at the end of the 20th century, and +0.9°C in the second half of the 12th century. The difference is +0.5 °C.
