NASA’s press office is on the ball. Pn May 12, according to NPR, they
held a press conference to discuss the stability of the West Antarctic Ice Sheet and its potential contribution to future sea level rise. The researchers announced that the ice sheet’s collapse is both underway and unstoppable.
Various media have covered this.
I suppose it is good that this phenomenon is in the public eye, but insofar as I know the only real progress is that that the pulse is at
least in part of Antarctic origin; by elimination it could come from nowhere but an ice sheet; the question was which on or which ones; ice
rafted debris has been found confirming an Antarctic source. But the large amplitude of MeltWater Pulse 1A itself is not really “news” in
the sense of being new.
To my knowledge the scale of this event is first discussed in Till Hanebuth, Karl Stattegger, Pieter M. Grootes; Science V 288 pp 1033 ff
The necessity for media to have a “news hook” before mentioning some publicly relevant information is unfortunate, but better late than
never I guess. I blogged about the aspect of it that gets peoples attention, in 2007 but I had no news hook.
Anyway, better late than never.
