Science diplomacy will play a large role in how indigenous people, the eight
circumpolar countries, and
other interested nations negotiate complicated economic, security, and environmental interests while attempting to maintain strong scientific ties, particularly with the new U.S. administration.
The
circumpolar countries have all mounted scientific expeditions to get that and
other evidence of prolongation (sediment thickness, rock type).
It's always worth remembering that the
other end of the AMOC involves two main factors: (1) vorticity - mixing of heat from surface waters into the deep abyssal ocean (which decreases density causing the Atlantic Deep Water to start rising above the colder Antarctic Bottom Water) and (2) the wind - driven upwelling around the Antarctic
Circumpolar Current.
Experts from the United States and
other Arctic nations have developed the first safety guidelines for operating unmanned drone aircraft in international airspace around the
circumpolar north.
This
circumpolar deep water, which is relatively warm and salty compared to
other parts of the Southern Ocean, has warmed and shoaled in recent decades, and can melt ice at the base of glaciers which reduces friction and allows them to flow more freely.
The study also found that the Southern Ocean
Circumpolar Current, which helps determine sea - ice extent, is steered by submerged ridges and canyons along the edge of the Antarctic continental shelf, rather than by global warming or
other climatic conditions.
While it is tempting to attribute the unexplained sea ice trends to
other factors such as increased upwelling of relatively warm
circumpolar deepwater (Thoma et al. 2008), an intensification of the hydrological cycle and increased ocean stratification (Liu and Curry 2010), or eastward propagation of sea ice anomalies (Holland et al. 2005), the observed northerly wind trends (Fig. 5a) are qualitatively consistent with the decrease in sea ice in the 30 ° W — 60 ° W sector.
This historic event brought together leaders from the eight Arctic nations and many
others, 25 in all, along with
circumpolar indigenous groups and top U.S. Arctic officials.
Other members of the board include elected representatives of the four regional land claims organizations — Nunavut Tunngavik Inc., Makivik Corporation, Nunatsiavut Government and the Inuvialuit Regional Corporation, as well as the presidents of the National Inuit Youth Council, Pauktuuit Inuit Women of Canada and the Inuit
