Russia Much Warmer During Holocene
By Paul Homewood
A new paper provides further evidence that temperatures for much of the Holocene were higher than now, this time in Central European Russia.

Novenko, E.Yu., Volkova, E.M., Glasko, M.P. and Zuganova, I.S. 2012. Palaeoecological evidence for the middle and late Holocene vegetation, climate and land use in the upper Don River basin (Russia). Vegetation History and Archaeobotany 21: 337-352.
Writing as background for their work, Novenko et al. (2012) state that "during the last 30 years, archaeological and palaeogeographical studies were undertaken in the central area of the East European Plain which includes the upper Don River and its tributary, the Nepryadva River," citing as examples of this work the studies of Folomeev et al. (1990), Khotinsky (1993), Glasko et al. (2000), Gonyanyi et al. (2007) and Novenko et al. (2009) and reporting that these multidisciplinary efforts, as they describe them, "focused initially on the reconstruction of natural landscapes at the time of the Kulikovo battle of 1380 (in which the Russians defeated the Tartar-Mongol forces)."
In their current paper, Novenko et al. (2012) discuss "new pollen and plant macrofossil evidence, backed by radiocarbon dates, resulting from the study of the key section ‘berezovskoye mire’ within the Kulikovo battlefield area, as well as the reconstruction of landscape and climate for the time span ranging from the mid-Atlantic period [7.2-5.7 cal. kyr B.P.] to the present." In doing so, the four Russian researchers report that temperatures during the mid-Atlantic period "were warmer than the present, mainly due to the higher winter temperatures," while noting that mean January temperatures were "about 3-5°C higher than the present climatic conditions." They also state that in the late Atlantic period, "the mean July and the mean annual temperatures rose to about 2°C higher than the present," after which, in the middle and late Subboreal period, they indicate that summer temperatures were "about 1-3°C higher than present values," while noting that that period’s "mean annual temperatures could have been 1-2°C higher."
It seems that the more one studies palaeoclimates in various places around the world, the more one begins to appreciate the fact that there is nothing unusual, unnatural or unprecedented about our planet’s current level of warmth, especially when it is realized that at these earlier times there was much less CO2 in the air than there is nowadays.
[The Subboreal period runs from around 4000BC to 400BC, according to Wikipedia]
