On average, Antarctic sea ice may be considerably thicker than once thought, which could significantly change how scientists assess sea ice dynamics and their interactions with the ocean in a warming world.

Sea level rise, ocean acidification and the rapid melting of massive ice sheets are among the significantly increased effects of human - induced global warming assessed in the survey, which also examines the emissions of heat - trapping gases that are causing the climate change.

To assess these implications, we translate global into local SLR projections using a model of spatial variation in sea - level contributions caused by isostatic deformation and changes in gravity as the Greenland and Antarctic ice sheets lose mass (36 ⇓ — 38), represented as two global 0.5 ° matrices of scalar adjustment factors to the ice sheets» respective median global contributions to SLR and (squared) to their variances.

Huntington's research activities include reviewing the regulation of subsistence hunting in northern Alaska, documenting traditional ecological knowledge of beluga whales and bowhead whales, examining Iñupiat Eskimo and Inuit knowledge and use of sea ice, and assessing the impacts of climate change on Arctic communities and Arctic marine mammals.

This report discusses our current understanding of the mechanisms that link declines in Arctic sea ice cover, loss of high - latitude snow cover, changes in Arctic - region energy fluxes, atmospheric circulation patterns, and the occurrence of extreme weather events; possible implications of more severe loss of summer Arctic sea ice upon weather patterns at lower latitudes; major gaps in our understanding, and observational and / or modeling efforts that are needed to fill those gaps; and current opportunities and limitations for using Arctic sea ice predictions to assess the risk of temperature / precipitation anomalies and extreme weather events over northern continents.

In their paper «Exploring recent trends in Northern Hemisphere blocking,» Barnes and colleagues used various meteorological definitions of «blocking» along with various datasets of atmospheric conditions to assess whether or not there have been any trends in the frequency of blocking events that could be tied to changes in global warming and / or the declines in Arctic sea icIn their paper «Exploring recent trends in Northern Hemisphere blocking,» Barnes and colleagues used various meteorological definitions of «blocking» along with various datasets of atmospheric conditions to assess whether or not there have been any trends in the frequency of blocking events that could be tied to changes in global warming and / or the declines in Arctic sea icin Northern Hemisphere blocking,» Barnes and colleagues used various meteorological definitions of «blocking» along with various datasets of atmospheric conditions to assess whether or not there have been any trends in the frequency of blocking events that could be tied to changes in global warming and / or the declines in Arctic sea icin the frequency of blocking events that could be tied to changes in global warming and / or the declines in Arctic sea icin global warming and / or the declines in Arctic sea icin Arctic sea ice.
