In 2024, the minimum extent of Arctic sea ice was recorded at 4.28 million square kilometers – approximately 1.8 million square kilometers below the long-term average. The rate of sea ice reduction is nearly 13% per decade, suggesting that the Arctic could become ice-free during the summer ...
The volume, extent and age of Arctic sea ice is in decline, yet winter sea ice production appears to have been increasing, despite Arctic warming being most intense during winter. Previous work suggests that further warming will at some point lead to a decline in ice production, however a co...

1. CISDA is a collection of daily and weekly ice charts prepared by the Canadian Ice Service (CIS) since 1968. A variety of sea ice information acquired from satellite-based monitoring, ship-based observation, and operational models are used to prepare the ice chart. Ice chart provides ...
Guest Post by Javier February is not over, and Arctic sea-ice extent is already over half a million square kilometers higher than last year at this day. The growing season has not ended, and 2019 Arctic sea-ice extent is already higher than the previous
Charts of Arctic sea ice extent since 1979 show a sharp downward trend, as the region warms at about twice the rate of the rest of the world. The decision was even more surprising considering that the Air Force had already shelled out $518 million to build and store the spacecraft, and...
The 2013 summer in Greenland also saw a reversal of the recent trend in summertime loss of surface snow and ice mass by run-off, as would be expected given the reduced melting. Figure 3 illustrates the relative melt area departure from the average (sum of the daily melt areas over the ...
University of Colorado at Boulder The movement of sea ice between Arctic countries is expected to significantly increase this century, raising the risk of more widely transporting pollutants like microplastics and oil, according to new research from CU B
The Arctic summer storm - which perhaps will be known as the Great Arctic Cyclone of 2012, time will tell - is slowly falling apart, losing its strength and position. It still remains to be seen what the total effect of this storm will be on the sea ice. There's the churning, the ...
19 gridded monthly sea ice data which synthesizes the (sparse) records of sea ice extent, primarily from hand-drawn charts50. Similarly, we use HadISST data21 for the Antarctic before the satellite era. The PIOMAS product20 blends ice concentration and sea-surface temperature data with a ...
