It is time for the monthly update of my extrapolation when the extent [Ausdehnung], volume [Volumen], thickness [Dicke] and area [Fläche] will reach zero. The extrapolation occured linearly and by a logarithmic function; the latter one almost constantly resulting in earlier times (valid for volume and thickness, not for extent and area in the winter months). The August value now includes 2020.

Volume in August 2020 is slightly above the long term trend, thickness for August 2020 lies almost at the long term trend lines, whereas extent and area dip slightly below it. The "BOE numbers" did not change (volume, thickness) and decreased by 1-2 years (extent, area) compared to August 2019.

So there is a tiny further convergence between the "late values" (area, extent) and the "early value" (volume).

The order (earlier → later BOE) generally is volume < thickness < area < extent.

Please note that this is not a forecast but a trend!

See attached table, now widened to see the linear function value (y-AA) at t = 0. stg = slope.
