The impact of Arctic amplification on the extratropical jets
… 1990's, greenhouse gas forcing has warmed the Arctic at twice the rate of lower latitudes, coinciding with a dramatic decline in Arctic sea ice extent. This manifestation of climate change has ignited a lively and ongoing debate regarding if Arctic warming will significantly influence extreme …

Far-flung influences on midlatitude weather and climate: The stratospheric pathway
… the response of the polar vortex to projected Arctic climate change, in terms of both the mean state and variability, before focusing on the impact of sudden stratospheric warmings (SSWs) on European energy demand. The “stratospheric pathway” proposed to link Arctic sea-ice loss to changes in …

Landslide generated tsunamis : numerical modeling and real-time prediction
… Storegga slide took place. The influence of Arctic warming on the stability of the Svalbard glacial margin is discussed. Based on new geophysical data, I present four possible landslide scenarios and compute the generated tsunamis. Waves of 6 m height would be capable of reaching northwest …

Effect of mass wasting on soil organic carbon storage and coastal erosion in permafrost environments
Accelerated permafrost thaw under the warming Arctic climate can have a significant impact on Arctic landscapes. Areas underlain by permafrost store high amounts of soil organic carbon (SOC). Permafrost disturbances may contribute to increased release of carbon dioxide and methane to the …

Variability, origin and physical characteristics of dust aerosol in Iceland
… in NE or in southern part of Iceland. The Arctic dust events (NE Iceland) were typically warm and during summer/autumn (May-September) while the Sub-Arctic dust events (S Iceland) were mainly cold and during winter/spring (March-May). A total of 32 severe dust storms (visibility < 500 m) …

Climatic drivers of retrogressive thaw slump activity and resulting sediment and carbon release to the nearshore zone of Herschel Island, Yukon Territory, Canada
… evolution of retrogressive thaw slumps under a warming scenario with summer air temperatures increasing by 2-3 °C by 2081-2100, would lead to an increase of 109-114% in release of sediment-meltwater. It can be concluded that retrogressive thaw slumps are sensitive to climatic conditions and …

Novel disturbance regimes in the Arctic: paleoecological perspectives on fire and thermo-erosion from Alaskan tundra
Anthropogenic warming is amplified in the northern high latitudes, and disturbance processes such as wildfire and thermo-erosion (i.e., ground subsidence transport of ice-rich sediments) have increased in frequency and magnitude in tundra ecoregions in recent decades. These novel disturbance …

The impact of tropical sea surface temperature perturbations on atmospheric circulation over north Canada and Greenland
Identifying the drivers of Arctic climate variability is essential for understanding the recent rapid changes in local climate and determining the mechanisms that cause them. Remote tropical sea surface temperatures (SST) have been identified in previous studies as having contributed to the recent …
