Second 1–Week Melt in the Arctic

Annual Average Sea Ice Extent
2018 was the 2nd lowest (start of the green graph) calendar year on record for annual average sea ice extent in the Arctic. After 2016, but before 2017. Since New Year we’ve climbed back up to 4th lowest, and per now it even seems likely we’ll leave this chart at the high end during March, …

Year-To-Date Average Sea Ice Volume
With 2018 ending at a 5th lowest average for the year for Arctic sea ice volume, we’re now up to the 6th lowest position per February 21st. These are however still early days, and a 52–day average, while much more reliable than a daily figure, is a lot less indicative of where the year is …
Year-To-Date Average Sea Ice Extent
With 2018 ending at a 2nd lowest average for the year for Arctic sea ice extent, and with the new year–to–date average at only the 8th lowest on record after the first week of January, we’re now down to the 5th lowest position per February 20th. These are however still early days, and a 51–day …
