Holocene Treeline History and Climate Change Across Northern Eurasia Radiocarbon-dated macrofossils are used to document Holocene treeline history across northern Russia (including Siberia). Boreal forest development in this region commenced by 10,000 yr B.P. Over most of Russia, forest advanced to or near the current arctic coastline between 9000 and 7000 yr B.P. and retreated to its present position by between 4000 and 3000 yr B.P. Forest establishment and retreat was roughly synchronous across most of northern Russia. Treeline advance on the Kola Peninsula, however, appears to have occurred later than in other regions. During the period of maximum forest extension, the mean July temperatures along the northern coastline of Russia may have been 2.5° to 7.0°C warmer than modern. The development of forest and expansion of treeline likely reflects a number of complimentary environmental conditions, ” Read abstract @ sciencedirect.com Less ice in the Arctic Ocean 6000-7000 years agohttps://wattsupwiththat.com/2010/09/08/inconvenient-ice-study-less-ice-in-the-arctic-ocean-6000-7000-years-ago/ They studied the beaches on the north coast of Greenland which these days is perennially bound in ice – even with our “alarming” summer extents and thicknesses that are to doom the planet. They looked at the raised beaches – higher sea levels (not much crustal rebound on Greenland), the plow marks made by ancient broken ice pack pushed onshore by wind, the beach itself which requires a good stretch of ocean with wind to build them and….wait for it… driftwood and other organic material that can be dated. Also Methane bubble scare debunked by experiment: Warming may not release Arctic carbon Element could stay locked in soil, 20-year study suggests BY ERIN WAYMAN 12:48PM, MAY 15, 2013 ........ They actually warmed up the land over years, as might simulate climatic change. The methane was simply not released from the soil as ASSUMED. So this part of the methane bubble claim is NOT supported by the closest thing to real world data we have. It is very telling how the field still relies on old assumptions in light of this. sciencenews.org And about that methane scare story: Why did the methane not get released during the Holcene period to cause unprecedented warming?
