Here, we analyse a 47-year air temperature record (1965-2011) at Tarfala Research Station (67° 54.7'N, 18° 36.7'E, 1135 m a.s.l.) in northern Sweden, and a nearby 11-year record of 100-m-deep ground temperature (2001-11; 1540 m a.s.l.). The air temperature record shows a mean annual air temperature of -3.5±0.9°C (±1 standard deviation s) and a linear warming trend of ±0.042°C yr-1. The warming trend shows large month-to-month variations with the largest trend in January followed by October. Also, the number of days with positive mean daily temperatures and positive degree-day sums has increased during the last two decades compared to the previous period. Temperature lapse rates derived from the mean daily Tarfala record and an air temperature record at the borehole site average 4.5°C km-1 and tend to be higher in summer than in winter. Mean summer air temperatures at Tarfala explain 76% of the variance of the summer glacier mass balance of nearby Storglacia¨ren. Consistent with the observed increase in Tarfala’s air temperature, the ground temperature record shows significant permafrost warming with the largest trend (0.047°C yr-1) found at 20 m depth.Keywords: Air temperature; climate change; permafrost; lapse rate; degree-days; NAO(Published: 15 July 2013)Citation: Polar Research 2013, 32, 19807, http://dx.doi.org/10.3402/polar.v32i0.19807 %B Polar Research %V 32 %G eng %U http://www.polarresearch.net/index.php/polar/article/view/19807 %0 Journal Article %J Science %D 2013 %T A Reconciled Estimate of Glacier Contributions to Sea Level Rise: 2003 to 2009 %A Alex S.

Sharp %A Jon Ove Hagen %A van den Broeke, Michiel R. %A Paul, Frank %X Glaciers distinct from the Greenland and Antarctic Ice Sheets are losing large amounts of water to the world’s oceans. However, estimates of their contribution to sea level rise disagree. We provide a consensus estimate by standardizing existing, and creating new, mass-budget estimates from satellite gravimetry and altimetry and from local glaciological records. In many regions, local measurements are more negative than satellite-based estimates. All regions lost mass during 2003–2009, with the largest losses from Arctic Canada, Alaska, coastal Greenland, the southern Andes, and high-mountain Asia, but there was little loss from glaciers in Antarctica. Over this period, the global mass budget was –259 ± 28 gigatons per year, equivalent to the combined loss from both ice sheets and accounting for 29 ± 13% of the observed sea level rise. %B Science %V 340 %P 852-857 %G eng %U http://www.sciencemag.org/content/340/6134/852.abstract %R 10.1126/science.1234532 %0 Journal Article %J Climate Dynamics %D 2013 %T Regional and global projections of twenty-first century glacier mass changes in response to climate scenarios from global climate models %A Valentina Radić %A Andrew Bliss %A Beedlow, A.Cody %A Regine Hock %A Miles, Evan %A J.
