I don't have any recent uptick representaion, of recent increasing
global sea-ice extent
I get, in millions of sq km, inexorable depletion of sea-ice
16 Jan 2017, 16.692
17 Jan, 16.593
18 Jan, 16.507
19 Jan, 16.455
20 Jan, 16.444
(would someone else check my figures?)
Anyone know which version is corrct?
I suspect Wipneus is using a different data feed than the Charctic one,
area rather than extent perhaps, JAXA ?
To put some context to these figures. When the oft reported break-off of
the Antarctic Larsen C ice sheet occurs, that loss of sea-ice would just
represent the same drop from just the 18 to the 19 Jan,ie 50,000 sq km
, in that tabulation of daily global sea-ice extent.
That event will no doubt get full coverage on the world media, but this
silent unobserved inexorable depletion gets no mention.
