Hoi Pascal,
We beleven een aparte tijd wat het zeeijs betreft.
Terwijl er -- sinds begin 1979!! -- op de Noordpool nog nooit zo weinig zeeijs was als nu, is er op de Zuidpool nog nooit zo véél zeeijs geweest als nu.
Edit: Ik zie inmiddels trouwens dat de betreffende grafiek is aangepast (zie *correction*)!
UPDATE: Wednesday, September 12, 2007 - *correction* - close to record SH sea ice maximum and NH sea ice minimum
Just when you thought this season's cryosphere couldn't be more strange .... The Southern Hemisphere sea ice area is close to surpassing the previous historic maximum of 16.03 million sq. km and is currently at 15.91 million sq. km. The observed sea ice record in the Southern Hemisphere (1979-present) is not as long as the Northern Hemisphere. Prior to the satellite era, direct observations of the SH sea ice edge were sporadic.
The NH sea ice area is currently at its historic minimum (2.92 million sq. km) representing a 27% drop in sea ice coverage compared to the previous (2005) record NH ice minimum.
Correction: we had previously reported that there had been a new SH historic maximum ice area. Unfortunately, we found a small glitch in our software. The timeseries have now been corrected and are showing that we are very close to, but not yet, a new historic maximum sea ice area for the Southern Hemisphere.
Groet,
Alwin
