We report the first high-resolution (20–50 years) mid- to late Holocene pollen records from Lake Teletskoye, the largest lake in the Altai Mountains, in south-eastern West Siberia.
Generally, the mid- to late Holocene (the last 4250 years) vegetation of the north-eastern Altai, as recorded in two studied sediment cores, is characterised by Siberian pine–spruce–fir forests that are similar to those of the present day.
Precipitation is relatively high (mean, 1299 mm), and about 70% of the annual precipitation falls in summer, especially from June to August (Korean Meteorological Administration,
Pollen studies are well suited to examining the impact of rapid climate change on terrestrial ecosystems because the reponse of vegetation to climate fluctuation is pronounced and can occur on decadal time scales (Tinner & Lotter, 2001).
2005CB422002-2), and the National Natural Science Foundation of China (Grant No.
Our pollen data reveal that the time period 9500–8000 cal a BP in southern China represents a climatic optimum for the Holocene characterized by hot and wet conditions.
This is consistent with the Holocene optimum found in lower latitude regions globally.
The papers have been sorted according to categories.
Again do feel free to bring this newest list to the attention of your lawmakers, and ask them if there might be much better things to do with the billions of dollars spent on junk climate measures.
Pollen analysis provides information that is unavailable from other sources and offers a unique and invaluable perspective on natural, climate-induced vegetation changes and environmental reconstruction (Birks & Birks, 1980; Davis, 1994) despite its limitations compared with marcropaleontology.
