Is it just me, or is there one more record to be broken? Looks to me like we have a real possibility at lowest Global Max?
CT SIA finally above -2 million km2 anomaly mark
After three full months the Cryosphere Today sea ice area anomaly trend line has finally left the zone below the 2 million square kilometre mark: As usual, Jim Pettit is serving the current statistical hors d'oeuvres: CT SIA area increased by 203k km2 yesterday; that was the fifth double centu...
Looking at the forecast for Churchill, it would seem like Hudson Bay is going to start melting out soon - http://www.weatheroffice.gc.ca/city/pages/mb-42_metric_e.html
Or am I jumping the gun here?
ASI 2012 update 1: a new beginning
During the melting season I'm writing (bi-)weekly updates on the current situation with regards to Arctic sea ice (ASI). Because of the demise of AMSR-E the IJIS sea ice extent (SIE) numbers are no longer central to these updates. Instead I now use Cryosphere Today sea ice area (SIA) numbers and...
John, is it really the case that the Arctic itself is absorbing less radiation? A couple thoughts to consider on that -
1) Most areas of the actual arctic basin are below or at average, the total area/extent being close to normal was driven by SOO, Bering and Baffin.
2) Is it just me, or are high pressures dominating more this year leading to more clear, sunny days. I lack the skills to really evaluate this empirically, but eyeballing the satellite photos from last year compared to this year seems to indicate yes. So even if the albedo was higher at the surface due to more ice cover, might it not be the case that more or equivalent radiation is being absorbed due to much more reaching the surface in the first place?
3) Snow cover also appears to be down, which may have an effect on melt at the edges of the basin as the summer progresses.
I don't know how to quantify these observations, just wanted to throw them out there for discussion.
