A short period of cooling about 1.3–1.4 ka BP could have been triggered by the increased volcanic activity recorded across the Northern Hemisphere.A new period of cooling started around 1100–1150 CE, with the minimum July temperatures occurring between 14 CE.Supported by the National Natural Science Foundation of China for Distinguished Youth Scholar (Grant No.40325002), the Key Research Project of the Knowledge Innovation Program of CAS (Grant Nos.A high-resolution pollen record of the past 13000 a from Huguangyan Maar Lake reveals the vegetation and environment changes in southern China during the Holocene.It shows that (i) pollen percentage of trees and shrubs reached 56% during the early Holocene (11600–7800 cal a BP), of which the pollen percentage of tropical trees reached a maximum at 9500-8000 cal a BP, reflecting a hot and wet environment; (ii) during the mid-Holocene (7800–4200 cal a BP), the pollen percentage of montane coniferous trees and herbs increased, while the percentage of tropical-subtropical trees decreased, indicating lower temperature and humidity; (iii) in the late Holocene spanning from 4200 to 350 cal a BP, the pollen percentage of herbs and montane conifer increased significantly, indicating a marked decrease of temperature and humidity.

Well, the number of skeptic papers seems to be accelerating as already this year there have been almost 50, and it’s only February!Pollen records discussed in the text are from the Paju-Unjeong site (A) and Pyeongtaek site (B). Correlation of pollen zones, with main trees and herbs, between the Pyeongtaek and Paju-Unjeong areas and forest history during the Holocene period (compiled from Jun et al., 2010 and Yi et al., 2011). Vegetation and climate changes based on pollen indicators in South Korea during the Holocene period. BD: Broadleaved deciduous The Korean Peninsula, surrounded by the sea on three sides (east, west, and south), is located on the eastern end of the Asian continent adjacent to the West Pacific and belongs to the temperate zone with four distinct seasons, which are largely controlled by the East Asian monsoon. Xia, 2006Holocene climate development on the central Tibetan Plateau: a sedimentary records from Cuoe Lake. Insolation (July), precipitation, and sea level are from Berger (1978), Hu et al. During the winter, from December to February, it is cold and dry due to the establishment of the strong Siberian anticyclone on the Tibetan Plateau.

ABSTRACT: This article offers a reconstruction of the vegetation and climate of the southwestern Siberian Baraba forest-steppe area during the last ca. The analysis of palynological data from the sediment core of Lake Bolshie Toroki using quantitative methods has made it possible to reconstruct changes of the dominant types of vegetation and mean July air temperatures.Coniferous forests grew in the vicinity of the lake, and mean July air temperatures were similar to present-day ones between 7.9 and 7.0 kyr BP.

The warmest and driest climate occurred at 7.0e5.0 kyr BP.
