Arctic ice extent A simple program to download and plot the arctic sea ice extent data available from the NSIDC (National Snow and Ice Data Center; http://nsidc.org/). Installation First, clone the repository and change into the project directory: $ git clone https://github.com/paultcochra...
The Arctic Sea Ice extent, sourced from the National Snow and Ice Data Center (NSIDC) and depicted as the blue curve in Fig. 4a, was acquired from the URL: https://nsidc.org/data/g02135/versions/3 [Accessed in Jan. 2021]. The Sea Ice extent data product is based on gridded fields...
values. While the sea-ice extent was reduced in the Arctic marginal seas in the early and middle Holocene (Extended Data Fig. 2), central Arctic site B28 was probably perennially ice covered throughout the Holocene39, suggesting that higher early and middle Holocene nitrate consumption occurred ...
This September, sea ice covering the Arctic Ocean fell to the sixth lowest extent in the satellite record, which began in 1979. All of the seven lowest extents have occurred in the last seven years, since 2007. Satellite data analyzed by NSIDC scientists
Two key climate change indicators - global surface temperatures and Arctic sea ice extent - have broken numerous records through the first half of 2016, according to NASA analyses of ground-based observations and satellite data. Each of the first six months of 2016 set a record as the warmest...

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 ...
