W. Brief communication: solar radiation management not as effective as CO2 mitigation for Arctic sea ice loss in hitting the 1.5 and 2 °C COP climate targets. Cryosphere 12, 3355–3360 (2018). Stroeve, J. C. et al. Trends in Arctic sea ice extent from CMIP5, CMIP3 and ...
The Sea Ice extent data product is based on gridded fields of sea ice concentration data derived from passive microwave radiometers and is commonly used for monitoring and analyzing changes in Arctic sea ice extent over time81. The dataset used to analyze the thinning of ice cover in the ...
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 ...
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...
(覆盖面积) for the year 2012,setting a record for the lowest summer cover since satellite data collection began.The sea ice extent has fallen to 3.41 million sq km on 18 September-50% lowerthan the 1979-2000 average.On August 26, sea ice extent fell to 4.10 million sq km, breaking the...
Wintertime Arctic sea ice extent has been declining since the late twentieth century, particularly over the Atlantic sector that encompasses the Barents-Kara Seas and Baffin Bay. This sea ice decline is attributable to various Arctic environmental changes, such as enhanced downward infrared (IR) radia...
Self-Organizing maps (SOMs) have been used to explore potential connections between atmospheric circulation over the Arctic (in the form of sea level pressure patterns and teleconnection indices) and sea ice loss. Extended periods of abrupt loss (rapid ice loss events, or RILEs) have been studied...
Our simulation efforts reveal similar boreal spring (March) sea ice extent in the LIG time slices as in the PI simulation. While sea ice concentrations were slightly lower in June during the early LIG (130 ka) and the middle LIG (125 ka) compared to PI concentrations, the largest ...
As shown in Supplementary Fig.10, the North Pacific is functionally ice-free for the entire year during 2080–2099. To understand to what extent the year-round lack of ice in the North Pacific specifically contributes to the frequency change of strong El Niño events, we conduct an additiona...
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...
