Solar energy reached a summer maximum (9% higher than at present) ~11 ka ago and has been decreasing since then, primarily in response to the precession of the equinoxes. The extra energy elevated early Holocene summer temperatures throughout the Arctic 1-3°C above 20th century averages, enough to completely melt many small glaciers throughout the Arctic, although the Greenland Ice Sheet was only slightly smaller than at present. Early Holocene summer sea ice limits were substantially smaller than their 20th century average, and the flow of Atlantic water into the Arctic Ocean was substantially greater. As summer solar energy decreased in the second half of the Holocene, glaciers re-established or advanced, sea ice expanded…<br /><br />A more recent paper looking at glaciers in Norway.<br /><br />A new approach for reconstructing glacier variability based on lake sediments recording input from more than one glacier January 2012<br />Kristian Vasskoga Øyvind Paaschec, Atle Nesjea, John F. Boyled, H.J.B. Birks<br /><br />…. A multi-proxy numerical analysis demonstrates that it is possible to distinguish a glacier component in the ~ 8000-yr-long record, based on distinct changes in grain size, geochemistry, and magnetic composition…. This signal is …independently tested through a mineral magnetic provenance analysis of catchment samples. Minimum glacier input is indicated between 6700–5700 cal yr BP, probably reflecting a situation when most glaciers in the catchment had melted away, whereas the highest glacier activity is observed around 600 and 200 cal yr BP. During the local Neoglacial interval (~ 4200 cal yr BP until present), five individual periods of significantly reduced glacier extent are identified at ~ 3400, 3000–2700, 2100–2000, 1700–1500, and ~ 900 cal yr BP….<br /><br />The authors of BOTH papers simply state that most glaciers likely didn’t exist 6,000 years ago, but the highest period of the glacial activity has been in the past 600 years. This is hardly surprising with ~9% less solar energy.<br />MORE:<br /><br />Holocene temperature history at the western Greenland Ice Sheet margin reconstructed from lake sediments – Axford et al. (2012)<br />“….As summer insolation declined through the late Holocene, summer temperatures cooled and the local ice sheet margin expanded. Gradual, insolation-driven millennial-scale temperature trends in the study area were punctuated by several abrupt climate changes, including a major transient event recorded in all five lakes between 4.3 and 3.2 ka, which overlaps in timing with abrupt climate changes previously documented around the North Atlantic region and farther afield at ∼4.2 ka…..”<br />http://www.sciencedirect.com/science/article/pii/S0277379112004209<br /><br />….the June 21 insolation minimum at 65N during MIS 11 is only 489 W/m2, much less pronounced than the present minimum of 474 W/m2. In addition, current insolation values are not predicted to return to the high values of late MIS 11 for another 65 kyr. We propose that this effectively precludes a ‘double precession-cycle’ interglacial [e.g., Raymo, 1997] in the Holocene without human influence….<br />http://web.pdx.edu/~chulbe/COURSES/QCLIM/reprints/LisieckiRaymo_preprint.pdf (NOTE: pdf has been removed from internet)<br /><br />Abstract<br />…..We therefore conclude that for a period in the Early Holocene, probably for a millenium or more, the Arctic Ocean was free of sea ice at least for shorter periods in the summer……<br />http://adsabs.harvard.edu/abs/2007AGUFMPP11A0203F<br /><br />Abstract<br />…..Arctic sea ice cover was strongly reduced during most of the early Holocene and there appear to have been periods of ice free summers in the central Arctic Ocean……<br />http://www.sciencedirect.com/science/article/pii/S0277379110003185Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4142988674703954802.post-31310538797564450812013-12-19T10:40:28.012-08:002013-12-19T10:40:28.012-08:00That's what happens during an interglacial - i...That's what happens during an interglacial - ice continues to melt until the next ice age occurs. The Little Ice Age ended 150 years ago and was the coldest period of the past 10,000 years, so yes, glaciers are melting faster now than 150 years ago. The solar maximum in the latter 20th century is the driver, not man.<br /><br />During the last interglacial [Eemian], sea levels were 31 feet higher than the present and Greenland 8C warmer than the present. There is no evidence that the current interglacial is any different.
