    It seems likely that we've passed the maximum for the 2020/21 refreeze, and so it's time for the first sea ice extent minimum poll of the year.
    The annual minimum typically occurs during September, so a lot of weather to come between now and then
    Using the NSIDC daily extent, the minima since 2010, in millions of km2, are:

    2020:    3.7
    2019:    4.1
    2018:    4.6
    2017:    4.6
    2016:    4.1
    2015:    4.4
    2014:    5.0
    2013:    5.0
    2012:    3.3
    2011:    4.3
    2010:    4.6

    Spreadsheets and other sea ice data can be accessed through the NSIDC here

    I'll try to get these polls up 5 or so days before the end of each month, and then close them at the end of the last day of the month. So give me a nudge if I forget!
