Arctic climate change update 2019
New observations confirm continued rapid warming in the Arctic, driving many of the changes underway in the region, including loss of sea ice and glacier coverage, as well as changes in terrestrial and
Arctic Ocean

Influence of high-latitude atmospheric circulation changes on summertime Arctic sea ice
The Arctic has seen rapid sea-ice decline in the past three decades, whilst warming at about twice the global average rate. Yet the relationship between Arctic warming and sea-ice loss is not well understood.

How does the SST variability over the western North Atlantic Ocean control Arctic warming over the Barents–Kara Seas?
<p>Arctic warming over the Barents–Kara Seas and its impacts on the mid-latitude circulations have been widely discussed. However, the specific mechanism that brings the warming still remains unclear.
-
Sea ice decline and 21st century trans-Arctic shipping routes
<p>The observed decline in Arctic sea ice is projected to continue, opening shorter trade routes across the Arctic Ocean, with potentially global economic implications. Here we quantify, using Coupled

Global warming hits Arctic sea ice wintertime extent
Arctic sea ice appears to have reached a record low winter-time maximum extent for the second year in a row, according to NASA scientists. The new record low follows record high temperatures in December,

The Arctic freshwater system in a changing climate
The World Climate Research Programme (WCRP) Climate and Cryosphere (CliC) Project, the Arctic Monitoring and Assessment Programme (AMAP) and the International Arctic Science Committee (IASC) have released

Regional variability of a projected sea ice‐free Arctic during the summer months
<p>Climate projections of sea ice retreat under anthropogenic climate change at the regional scale and in summer months other than September have largely not been evaluated. Information at this level of

Mapping the future expansion of Arctic open water
Sea ice impacts most of the Arctic environment, from ocean circulation and marine ecosystems to animal migration and marine transportation. Sea ice has thinned and decreased in age over the observational

Microplastics in Arctic polar waters: the first reported values of particles in surface and sub-surface samples
<p>Plastic, as a form of marine litter, is found in varying quantities and sizes around the globe from surface waters to deep-sea sediments. Identifying patterns of microplastic distribution will benefit
-
Impact of aerosol emission controls on future Arctic sea ice cover
<p>We examine the response of Arctic sea ice to projected aerosol and aerosol precursor emissions changes under the Representative Concentration Pathway (RCP) scenarios in simulations of the Canadian Earth

Erosion of organic carbon in the Arctic as a geological carbon dioxide sink
Measurements of sediments eroded by the Mackenzie River reveal the widespread export of permafrost-derived biospheric carbon that is several thousand years old, and demonstrate its burial in the Arctic
