In this blog post, I (Damien Ringeisen) reshape a Twitter thread<\/a> that I published on November 3rd, 2021.<\/em><\/span><\/p>\n\n\n\n Today, as the COP26 started a few days ago, I would like to help you visualize the reduction of sea ice in the Arctic Ocean.<\/p>\n\n\n\n For simplicity, we will compare two years:<\/p>\n\n\n\n And we will look at the sea ice conditions at the September sea ice minimum extent: Each year in September, there is a day when the area covered by sea ice is minimum. It is the day when sea ice, globally, stops melting and starts to freeze again.<\/p>\n\n\n\n For this data, we will look at the data from the NSIDC<\/a>. They indicate that the minimum extent was <\/p>\n\n\n\n But sea ice extent is not the only data we want to visualize. Let’s get the estimation of the sea ice volume from PIOMAS<\/a>. (We already used PIOMAS data set in The Arctic Stripes<\/a> )<\/p>\n\n\n\n From PIOMAS, we get the arctic sea ice volume on the same dates <\/p>\n\n\n\n Now that we have the data, let’s draw ice cubes: For each date, we draw an ice cube with: <\/p>\n\n\n\n Of course, we cannot draw horizontal and vertical dimensions at the same scale; otherwise, one would need a screen the size of the Arctic ocean to visualize it. <\/p>\n\n\n\n So we exaggerate the vertical dimension. <\/p>\n\n\n\n However, we draw both ice cubes at the same scale so we can compare them.<\/p>\n\n\n\n Et voil\u00e0!
An ice cube comparison of sea ice extent and volume at the minimum sea ice extent of 1979 and 2021:<\/p>\n\n\n\n
