3.25 If memory serves me correctly, that was my previous guesstimate. Repeating it reflects my assessment that the slow start will not strongly affect the September outcome. The original rationale was a guesstimate that 2012 did indeed represent a regime change, and that the process of ice loss would end up taking us 10% below the 2012 value.

Excellent summary, Neven. This bit: "As the melting season ends, it feels as if things are only beginning. The age of consequences." ...really spoke for me.

Cool! And from a 'bird' designed to deliver information on wind... But I have to wonder how homogenous this year's data is? Presumably IJIS have done what they can to splice the data as adroitly and as accurately as possible? Oh well, that won't affect our ability to follow day to day changes--though historical context will remain somewhat problematic, I suspect.
