The observed net loss of -0.52 m / a in
glacier mass spread over the melt season is equivalent to 2.45 m3 / s in Thunder Basin, which is 10 % of the mean summer streamflow.
Of course it would be nice to know exactly how and when we're going to really suffer — abrupt CC, runaway GW,
mass extinction event, or just a linear ratcheting up of the same (floods, droughts, heatwaves, sea rise / land loss, disease
spread, mega-storms,
glacier melt, famines).
