The sea-ice effect on the solar radiation fluctuates seasonally with the solar flux and decreases interannually in synchronisation with the decreasing sea-ice extent. A disappearance of the Arctic ice cap during the sunlit period of the year would radically reduce the local albedo and cause a ...
One consequence has been a rapid decline in Arctic sea ice over the past 3 decades?a decline that is projected to continue by state-of-the-art models. Many stakeholders are therefore interested in how global warming may change the timing and extent of sea ice Arctic-wide, and for specific...
While many models have been used to study the predictability of climate variables, their performance in predicting sea ice was not well assessed. This study examines the predictability of the Arctic sea ice extent from ensemble prediction systems. The analysis is focused on verification of ...

Image: DMI Arctic Plots Sea Ice Extent The National Snow And Ice Data center (NSIDC) analysis of August 4, 2024 shows that the Arctic sea ice extent in July 2024 has been stable for 17 years, without any […] Posted in Arctic | 4 Responses...
The snow cover extent between May and June has decreased by 21% over the 1971–2019 period1; this is a percent loss rate greater than the loss of sea ice in September. Both rainfall and snow dynamics are among the key factors driving soil moisture availability that, at the same time, ...
global warming has led to widespread shrinking of the cryosphere, with mass loss from ice sheets and glaciers (very high confidence), reductions in snow cover (high confidence) and Arctic sea ice extent and thickness (very high confidence), and increased permafrost temperature (very high confidence...
All these models project a decline in summer Arctic sea ice extent over the next decades (Fig. 1).Nonetheless, large uncertainties remain regarding the magnitude and timing of future changes in the sea ice cover. This was already underlined for CMIP3, the previous round of model intercomparison...
Arctic sea ice extent (SIE) achieves its minimum in September each year and this value has been observed to decline steeply over the satellite era of the past three decades. Yet large year-to-year fluctuations are also present in the September SIE and th
Variations in Sea Ice Extent We now compare the annual components of sea ice extent NHSI (Figure 7) and SHSI (Figure 8) with those of 𝑚1m1 and lod, in particular, their phases (Table 1). In the case of the northern hemisphere (Arctic), variations in sea ice extent are almost ...
