   The UW has updated its PIOMAS Arctic seaice volume to end of Feb 2021.   
      
   It finds the vol for the month was 19122 km3 making it the 3rd-lowest   
   Feb in the 43y sat record.   
      
   From the PIOMAS vol and NASA-RT Arctic extent was can estimate the   
   average thickness of seaice at 1.343 about equal 5th thinnest for Feb   
   since records began in 1979. The trend shows a decline of around   
   1.3+-0.2 cm per year across the dataset pointing to the critical   
   1m thickness being reached within 30y.   
      
   The Top 10 lowest tables are now:   
      
   Feb Arc seaice volume   
   Year	Vol (000s km3)   
   2017	17.366
