Enabling cross-sectoral transformation for coastal climate adaptation in Europe: Four directions for interdisciplinary efforts
Coastal areas in Europe are of immense value – not only to their residents but also to communities further inland. At the same time, they are particularly vulnerable to the impacts of climate change. The current pace of coastal climate adaptation remains slow, constrained by underfunding and the fragmented, sectoral nature of many initiatives. This calls for radically new yet practical approaches. In this perspective, a group of European research…
Still Arctic?—The changing Barents Sea
The Barents Sea is one of the Polar regions where current climate and ecosystem change is most pronounced. Here we review the current state of knowledge of the physical, chemical and biological systems in the Barents Sea. Physical conditions in this area are characterized by large seasonal contrasts between partial sea-ice cover in winter and spring versus predominantly open water in summer and autumn. Observations over recent decades show that s…
Key indicators of Arctic climate change: 1971–2017
Key observational indicators of climate change in the Arctic, most spanning a 47 year period demonstrate fundamental changes among nine key elements of the Arctic system. We find that, coherent with increasing air temperature, there is an intensification of the hydrological cycle, evident from increases in humidity, precipitation, river discharge, glacier equilibrium line altitude and land ice wastage. Downward trends continue in sea ice thicknes…
Arctic climate shifts drive rapid ecosystem responses across the West Greenland landscape
Prediction of high latitude response to climate change is hampered by poor understanding of the role of nonlinear changes in ecosystem forcing and response. While the effects of nonlinear climate change are often delayed or dampened by internal ecosystem dynamics, recent warming events in the Arctic have driven rapid environmental response, raising questions of how terrestrial and freshwater systems in this region may shift in response to abrupt …
Global sea-level contribution from Arctic land ice: 1971–2017
The Arctic Monitoring and Assessment Program (AMAP 2017) report identifies the Arctic as the largest regional source of land ice to global sea-level rise in the 2003-2014 period. Yet, this contextualization ignores the longer perspective from in situ records of glacier mass balance. Here, using 17 (>55 N latitude) glacier and ice cap mass balance series in the 1971-2017 period, we develop a semi-empirical estimate of annual sea-level contribution…
Statistical EOF analysis of spatiotemporal glacier mass-balance variability: A case study of Mittivakkat Gletscher, SE Greenland
An Empirical Orthogonal Function (EOF) variance analysis was performed to map in detail the spatiotemporal variability in individual stake mass-balances (ba) on Mittivakkat Gletscher (MG) – in a region where at present five out of ~20.000 glaciers have mass-balance observations. The EOF analysis suggested that observed ba was summarized by two modes: EOF1 and EOF2 represented 80% (significant) and 6% (insignificant) of the explained variance, res…
Glacier changes in the circumpolar Arctic and sub-Arctic, mid-1980s to late-2000s/2011
A new inventory record of satellite-derived area, length, elevation range and surface slope changes from the mid-1980s to late 2000s/2011 for 317 land-terminating glaciers and ice caps (GIC) is presented. The investigated GIC are located in 12 geographic regions throughout the circumpolar Arctic and sub-Arctic. This geographic subdivision allows us to examine regional variations in recent glacier changes. The method is based on a semi-automated c…
Fluctuations of sediment accumulation rates in front of an Arctic delta in Greenland
An automated layer counting technique is developed to estimate the chronology of a marine sediment core and this technique is validated with Pb 210 chronology. The marine sediment core was sampled in front of the delta of Mittivakkat Glacier meltwater river in the Sermilik Fjord, SE Greenland, and is a proxy of the sediment delivery from a glacial drainage basin to a fjord. The estimated time series was based on automatic lamination detection (va…

Recent warming in Greenland in a long-term instrumental (1881–2012) climatic context: I. Evaluation of surface air temperature records
We present an updated analysis of monthly means of daily mean, minimum and maximum surface air temperature (SAT) data from Greenland coastal weather stations and from a long-running site on the Greenland ice sheet, and analyse these data for evidence of climate change, especially focusing on the last 20 years but using the whole periods of available records (some since 1873). We demonstrate very strong recent warming along the west coast of Green…

Climate-driven fluctuations in freshwater flux to Sermilik Fjord, East Greenland, during the last 4000 years
The freshwater runoff from the glaciated and snow-covered Sermilik Fjord catchment, SE Greenland, was estimated at annual resolution for the period 1900–2008 and at decadal resolution for the past four millennia. Our simulations were forced with available meteorological station data (1900–2008) and Greenland ice core estimated temperature data (1899 bc–ad 1980) from Dye3 and GISP2. Time series of estimated ice discharge (2000–2009) for the three …

A test of classification and regionalisation of Danish watercourses
A classification of watercourses proposed by Hasholt 1999 has been tested in Denmark using data from detailed field investigations from 42 watercourses and their surrounding area. Three types of landscapes are included: the moraine landscape from the Weichselian glaciation, the moraine landscape from the Saalian glaciation and the outwash plains. The performance of the classification in separating types of watercourses is discussed and modificati…

Arctic climate shifts drive rapid ecosystem responses across the West Greenland landscape
Prediction of high latitude response to climate change is hampered by poor understanding of the role of nonlinear changes in ecosystem forcing and response. While the effects of nonlinear climate change are often delayed or dampened by internal ecosystem dynamics, recent warming events in the Arctic have driven rapid environmental response, raising questions of how terrestrial and freshwater systems in this region may shift in response to abrupt …
Still Arctic?—The changing Barents Sea
The Barents Sea is one of the Polar regions where current climate and ecosystem change is most pronounced. Here we review the current state of knowledge of the physical, chemical and biological systems in the Barents Sea. Physical conditions in this area are characterized by large seasonal contrasts between partial sea-ice cover in winter and spring versus predominantly open water in summer and autumn. Observations over recent decades show that s…

The current pace of coastal climate adaptation remains slow, constrained by underfunding and the fragmented, sectoral nature of many initiatives. This calls for radically new yet practical approaches. In this perspective, a group of European research…
