Reconstructed changes in Arctic sea ice over the past 1,450 years
A network of high-resolution terrestrial proxies from the circum-Arctic region is used to reconstruct past extents of summer sea ice, and shows that both the duration and magnitude of the current decline in sea ice seem to be unprecedented for the past 1,450 years.
A 10,000-Year Record of Arctic Ocean Sea-Ice Variability—View from the Beach
A sea-ice record from northern Greenland covering the past 10,000 years is presented and the lack of uniformity in past sea- ice changes, which is probably related to large-scale atmospheric anomalies such as the Arctic Oscillation, is not well reproduced in models.
The emergence of modern sea ice cover in the Arctic Ocean.
In the Eurasian sector of the Arctic Ocean, ice-free conditions prevailed in the early Pliocene until sea ice expanded from the central Arctic Ocean for the first time ca.
New observations of Arctic sea ice from satellite radar altimetry
Satellite observations of Arctic sea ice have observed a decline in extent for all months since 1979. The decline is coincident with abrupt global and Arctic warming over the last 30 years. Over this
Arctic sea-ice decline archived by multicentury annual-resolution record from crustose coralline algal proxy
The 646-y multisite record from the Canadian Arctic indicates that during the Little Ice Age, sea ice was extensive but highly variable on subdecadal time scales and coincided with an expansion of ice-dependent Thule/ Labrador Inuit sea mammal hunters in the region.
Natural variability of the Arctic Ocean sea ice during the present interglacial
It is suggested that seasonally ice-free conditions in the southeastern Arctic Ocean with a dominant Arctic dipolar pattern, may be a recurrent feature under “warm world” climate.
Canadian Arctic sea ice reconstructed from bromine in the Greenland NEEM ice core
A clear relationship between temperature and first- year sea ice extent in the Arctic is demonstrated and multi-year sea ice will continue to decline as polar amplification drives Arctic temperatures beyond the 2 °C global average warming target of the recent COP21 Paris climate agreement.
The Arctic-Subarctic sea ice system is entering a seasonal regime: Implications for future Arctic amplification
It is shown that the Arctic-Subarctic, i.e. the northern hemisphere, sea ice now exhibits similar levels of seasonality to the Antarctic, which is in a seasonal regime without significant change since satellite observations began in 1979.


Variations in the age of Arctic sea‐ice and summer sea‐ice extent
Three of the past six summers have exhibited record low sea‐ice extent on the Arctic Ocean. These minima may have been dynamically induced by changes in the surface winds. Based on results of a

Twenty-First-Century Climate Impacts from a Declining Arctic Sea Ice Cover
A steady decline in Arctic sea ice has been observed over recent decades. General circulation models predict further decreases under increasing greenhouse gas scenarios. Sea ice plays an important
Reconstructing Sea Ice Conditions in the Arctic and Sub‐Arctic Prior to Human Observations
Sea ice is a sensitive parameter characterized by a high variability in space and time that can be reconstructed from paleoclimatological archives. The most direct indication of past sea ice cover is
A millennial‐scale record of Arctic Ocean sea ice variability and the demise of the Ellesmere Island ice shelves
Sea‐ice ice shelves, at the apex of North America (>80° N), constitute the oldest sea ice in the Northern Hemisphere. We document the establishment and subsequent stability of the Ward Hunt Ice
Southern Ocean sea-ice extent, productivity and iron flux over the past eight glacial cycles
Continuous chemical proxy data spanning the last eight glacial cycles from the Dome C Antarctic ice core constrain winter sea-ice extent in the Indian Ocean, Southern Ocean biogenic productivity and Patagonian climatic conditions and observe large glacial–interglacial contrasts in iron deposition, which is infer reflects strongly changing Patagonia conditions.
Perspectives on the Arctic's Shrinking Sea-Ice Cover
Although the large scatter between individual model simulations leads to much uncertainty as to when a seasonally ice-free Arctic Ocean might be realized, this transition to a new arctic state may be rapid once the ice thins to a more vulnerable state.
Response of Sea Ice to the Arctic Oscillation
Abstract Data collected by the International Arctic Buoy Programme from 1979 to 1998 are analyzed to obtain statistics of sea level pressure (SLP) and sea ice motion (SIM). The annual and seasonal
