@helenafricker @X The question is, how can we remain in solidarity - and in constructive conversation - on social media despite this divide and rule mentality of and within the platforms.

Today is π-day and NASA's Image of the Day features some information that @HazLovell and I provided (independently). An alternative title that I suggested was "An Ice Pi with Swiss Cheese". https://t.co/irCL7CiiBH

@RobbieMallett @igsoc Please email the AnnGlaciol sea ice issue’s Associate Chief Editor (Christian Haas) directly with this complaint, and cc me (IGS Chief Editor). I am trying my best to chase all editors and we often send reminder emails for them to take action. Let’s find a solution for your case.

[Hester Jiskoot @glasheologist]

@tephrafan Nice work Duane, and a well-written paper.

I'm back on this hellish platform to share something important: the Randolph Glacier Inventory (RGI) version 7.0 is released!

Calculating frontal ablation is complicated and incl. measurements of ice flow (ITS_LIVE & MEaSUREs), margin changes (from Landsat, ASTER, RadarSat), ice thickness (from Operation Icebridge & BedMachine), volume change (geodetic mass balance) & surface mass balance models (RACMO)

[Hester Jiskoot @glasheologist]

Total glacier mass balance consists of two components: climatic-basal mass balance and frontal ablation. Our paper is the first to calculate frontal ablation for entire Greenland and we find that frontal ablation is the dominant mass loss component.
