  Rapid retreat of Greenland's marine-terminating glaciers coincides with regional warming trends, which have broadly been used to explain these rapid changes. However, outlet glaciers within similar climate regimes experience widely contrasting retreat patterns, suggesting that the local fjord geometry could be an important additional factor. To assess the relative role of climate and fjord geometry, we use the retreat history of Jakobshavn Isbræ, West Greenland, since the Little Ice Age (LIA) maximum in 1850 as a baseline for the parameterization of a depth- and width-integrated ice flow model. The impact of fjord geometry is isolated by using a linearly increasing climate forcing since the LIA and testing a range of simplified geometries. We find that the total length of retreat is determined by external factors – such as hydrofracturing, submarine melt and buttressing by sea ice – whereas the retreat pattern is governed by the fjord geometry. Narrow and shallow areas provide pinning points and cause delayed but rapid retreat without additional climate warming, after decades of grounding line stability. We suggest that these geometric pinning points may be used to locate potential sites for moraine formation and to predict the long-term response of the glacier. As a consequence, to assess the impact of climate on the retreat history of a glacier, each system has to be analyzed with knowledge of its historic retreat and the local fjord geometry.

  Marine-terminating glaciers and ice streams are important controls of ice sheet mass balance. However, understanding of their long-term response to external forcing is limited by relatively short observational records of present-day glaciers and sparse geologic evidence for paleo-glaciers. Here we use a high-resolution ice sheet model with an accurate representation of grounding line dynamics to study the deglaciation of the marine-based south-western Norwegian sector of the Scandinavian Ice Sheet and its sensitivity to ocean and atmosphere forcing. We find that the regional response to a uniform climate change is highly dependent on the local bedrock topography, consistent with ice sheet reconstructions. Our simulations suggest that ocean warming is able to trigger initial retreat in several fjords, but is not sufficient to explain retreat everywhere. Widespread retreat requires additional ice thinning driven by surface melt. Once retreat is triggered, the underlying bedrock topography and fjord width control the rate and extent of retreat, while multi-millennial changes over the course of deglaciation are modulated by surface melt. We suggest that fjord geometry, ice-ocean interactions and grounding line dynamics are vital controls of decadal-to centennial scale ice sheet mass loss. However, we postulate that atmospheric changes are the most important drivers of widespread ice sheet demise, and will likely trump oceanic influence on future ice sheet mass loss and resulting sea level rise over centennial and longer time scales.

  Recent and past retreat of marine-terminating glaciers are broadly consistent with observed ocean warming, yet responses vary significantly within regions experiencing similar ocean conditions. We assess how fjord geometry modulates glacier response to a regional ocean warming on decadal to millennial time scales, by using an idealized, numerical model of fast-flowing glaciers including a crevasse-depth calving criterion. Our simulations show that, given identical climate forcing, grounding line responses can differ by tens of kilometers due to variations in channel width. We identify fjord mouths and embayments as vulnerable geometries, showing that glaciers in these fjords are prone to rapid, irreversible retreat, independent of the presence of a fjord sill. This irreversible retreat has relevance for the potential future recovery of marine ice sheets, if the current anthropogenic warming is reduced, or reversed, as well as for the response of marine ice sheets to past climate states; including the warm Bølling-Allerød interstadial, the Younger Dryas cold reversal and the Little Ice Age.

  Understanding of long-term dynamics of glaciers and ice caps is vital to assess their recent and future changes, yet few long-term reconstructions using ice flow models exist. Here we present simulations of the maritime Hardangerjøkulen ice cap in Norway from the mid-Holocene through the Little Ice Age (LIA) to the present day, using a numerical ice flow model combined with glacier and climate reconstructions. In our simulation, under a linear climate forcing, we find that Hardangerjøkulen grows from ice-free conditions in the mid-Holocene to its maximum extent during the LIA in a nonlinear, spatially asynchronous fashion. During its fastest stage of growth (2300–1300 BP), the ice cap triples its volume in less than 1000 years. The modeled ice cap extent and outlet glacier length changes from the LIA until today agree well with available observations. Volume and area for Hardangerjøkulen and several of its outlet glaciers vary out-of-phase for several centuries during the Holocene. This volume–area disequilibrium varies in time and from one outlet glacier to the next, illustrating that linear relations between ice extent, volume and glacier proxy records, as generally used in paleoclimatic reconstructions, have only limited validity. We also show that the present-day ice cap is highly sensitive to surface mass balance changes and that the effect of the ice cap hypsometry on the mass balance–altitude feedback is essential to this sensitivity. A mass balance shift by +0.5 m w.e. relative to the mass balance from the last decades almost doubles ice volume, while a decrease of 0.2 m w.e. or more induces a strong mass balance–altitude feedback and makes Hardangerjøkulen disappear entirely. Furthermore, once disappeared, an additional +0.1 m w.e. relative to the present mass balance is needed to regrow the ice cap to its present-day extent. We expect that other ice caps with comparable geometry in, for example, Norway, Iceland, Patagonia and peripheral Greenland may behave similarly, making them particularly vulnerable to climate change.

  Observations of marine outlet glaciers covering the last few decades show speedup and accelerated retreat, and the geologic record testaments that catastrophic changes occurred also in the past. However, the time scales of rapid outlet glacier retreat and the underlying drivers are still unclear. Here, we study the collapse of Hardangerfjorden glacier, an outlet glacier of the Scandinavian Ice Sheet, during the transition from the Younger Dryas cold period to the warming in early Holocene. We use dated terminal and lateral moraines as constraints for a simple ice flow model including calving. Our experiments suggest a fast and highly variable retreat history driven by surface melt and warming fjord waters, paced by fjord bathymetry as well as ice shelf dynamics. Grounding line retreat in response to the rapid, large early Holocene warming is simulated at rates below 200 m/a, punctuated by brief spells of swift retreat exceeding 500 m/a. Our findings imply that warming subsurface waters will continue to drive retreat of marine outlet glaciers in Greenland and elsewhere, but that recent elevated retreat rates observed are not likely to be sustained longer than a few decades. On centennial scales, retreat will likely be increasingly driven by a warming atmosphere.

  Climate changes following the last glacial maximum (∼21-10ka BP) are considered some of the most dramatic and wide reaching abrupt events of the geological past. On Greenland the transition from the last glacial maximum to the Bølling-Allerød (BA) warm period was extremely abrupt, as is the transitions in and out of the Younger Dryas (YD) cold period. In terms of ocean changes, there are indications from proxy records that the large scale Atlantic Meridional Overturning Circulation (AMOC) was significantly reduced a few thousand years before the BA and again at the start of the YD. However, the link between changes in AMOC and climate in the Northern Hemisphere and in particular on Greenland is unclear. Here, we study changes to climate and circulation in the North Atlantic across these key climate transi- tions based on a sediment core from the Nordic Seas as well as sensitivity studies with a global climate model. Preliminary results suggest that changes in sea ice and stratification of the Nordic Seas played a key role in the observed climate changes during and preceding the deglaciation of the large land based ice sheets. In particular the cold period following Heinrich Event 1 (H1) and ending at the BA as well as the cold YD are associated with expansions of Arctic sea ice into the Nordic Seas region.

• Paasche, Øyvind & Nisancioglu, Kerim Hestnes (2017). A stepwise procedure for science communication in the field. Show summary

  Communicating and disseminating earth science to laypersons, high-school students and their teachers are becoming increasingly important considering the overwhelming impact human civilization have on the planet. One of the main challenges with this type of dissemination arises from the cross-disciplinary nature of the Earth system as it encompasses anything from cloud physics to the geological evidence of ice ages being played out on millennial time scales. During the last four years we have tested and developed an approach referred to as «Turspor» which can be translated to ‘Trail Tracks’. The ambition with “Turspor” is to inspire participants to seek in-depth knowledge relating to observations of features made in the field (glacial moraines, active permafrost, clouds, winds and so forth) as we have come to learn that observations made in the field enhances students capability to grasp the bare essentials related to the phenomena in question. By engaging master and PhD students in the process we create a platform where students can improve their teaching and communicative skills through a stepwise procedure. The initial concept was tested on 35 high school students during the summer of 2012 in the mountainous area of Snøheim on Dovre, Southern Norway. Before the arrival of the high school students, the university students prepared one page written summaries describing relevant geological or meteorological features and trained on how to best disseminate a basic scientific understanding of these. Specific examples were patterned ground caused by permafrost, glacier flour, katabatic winds, and equilibrium line altitude of glaciers. Based on the success of the program over the past 4 years with field trips together with local schools, we are in the process of developing the concept to be offered as a course at the master and PhD level, including a week of training in didactics applied to topics in the geosciences as well as practical training in the field. The university students who complete the course will be in charge of guiding local high school students in the field (mostly at university field stations in the mountains of Norway), as well as follow up on the topics discussed in collabora- tion with the high-school teachers during a subsequent visit to the classroom. By participating in the program, high-school students will experience inquiry-based learning, adding to their understanding of the scientific process. Sites developed through this program so far have been documented with a GPS tag, detailed description, background and pictures and hosted by the Norwegian Trekking Association website: ut.no as well as an associated app. The stepwise procedure of this concept has been developed through continous interaction with teachers, students and the general public. As a consequence, our capability to address and explain many earth science features of large societal relevance such as glacier retreat, thawing permafrost, flooding, snow avalanches, vegetation dynamics and climate change in general has been greatly improved.
