The Thermal State of Permafrost in the Nordic Area during the International Polar Year 2007-2009
Hanne H. Christiansen,Hanne H. Christiansen,Bernd Etzelmüller,Ketil Isaksen,H. Juliussen,Herman Farbrot,Ole Humlum,Ole Humlum,Margareta Johansson,Margareta Johansson,Thomas Ingeman-Nielsen,Lene Kristensen,Jan Hjort,Per Holmlund,A. B. K. Sannel,Charlotte Sigsgaard,H. J. Åkerman,Niels Nielsen Foged,Lars Harald Blikra,M. A. Pernosky,Rune S. Ødegård +20 more
TL;DR: In this paper, the authors provide a snapshot of the permafrost thermal state in the Nordic area obtained during the International Polar Year (IPY) 2007-2009 Several intensive research campaigns were undertaken within a variety of projects to obtain this snapshot.
Journal ArticleDOI
Degrading permafrost puts Arctic infrastructure at risk by mid-century
Jan Hjort,Olli Karjalainen,Juha Aalto,Sebastian Westermann,Vladimir E. Romanovsky,Frederick E. Nelson,Bernd Etzelmüller,Miska Luoto +7 more
TL;DR: It is shown that most fundamental Arctic infrastructure and population will be at high hazard risk, even if the Paris Agreement target is achieved, and fundamental engineering structures at risk by 2050.
Journal ArticleDOI
Why geodiversity matters in valuing nature's stage
TL;DR: It is found that geosites are important to biodiversity because they often support rare or unique biota adapted to distinctive environmental conditions or create a diversity of microenvironments that enhance species richness.
Journal ArticleDOI
Recent vegetation changes at the high‐latitude tree line ecotone are controlled by geomorphological disturbance, productivity and diversity
Risto Virtanen,Miska Luoto,Teppo Rämä,Kari Mikkola,Jan Hjort,John-Arvid Grytnes,H. John B. Birks,H. John B. Birks,H. John B. Birks +8 more
TL;DR: In this paper, the authors test how productivity, disturbance rate, plant functional composition and species richness gradients control changes in the composition of high-latitude vegetation during recent climatic warming.
Journal ArticleDOI
Global variation in the beta diversity of lake macrophytes is driven by environmental heterogeneity rather than latitude

TL;DR: Gecheva et al. as mentioned in this paper proposed a method to identify the root cause of gender discrimination in the media and found that women are more likely to be discriminated against than men.
