Arctic temperature is still not above 0°C – the latest date in fifty years of record keeping

The average arctic temperature is still not above (take your pick) 32°F 0°C 273.15°K–this the latest date in fifty years of record keeping that this has happened. Usually it is beginning to level off now and if it does so, it will stay near freezing on average in the arctic leading to still less melting than last summer which saw a 9% increase in arctic ice than in 2007.  H/T to FredM and MarcM

Data from DMI (Danish Meteorological Institute)

[NOTE: as a second source to Joe’s article I’ve added this weather station data from the “North Pole Cam” operated by NOAA. Link is here: http://www.arctic.noaa.gov/gallery_np.html [4]

There is a webcam at the “North Pole” (at least it starts out very near there) that reports via satellite data uplink at regular intervals. They also have a weather station [5] with a once weekly data plot.  Note it is still below zero centigrade there.

Latest data (updated approximately weekly) Readers should note that the station really isn’t at the north pole anymore due to significant ice drift [7].  – Anthony ]

The AMSR-E shows the ice situation on June 23rd:

See where we stand relative to recent years in terms of total extent here. [8] We are using JAXA-IJIS AMSR-E data to track ice as NSIDC is using older satellites and the new director Mark Serreze has proven untrustworthy. The next two months will be interesting. Temperatures usually begin flatlining in late June which would suggest less ice loss, although the water temperature beneath plays a key role and all of the warm water that entered the Arctic when the Atlantic was very warm in the middle 2000s (now is nearer normal) may not have circulated out yet.

The other question is what effect the early spring Mt. Redoubt eruptions may be having. Are the sulfate aerosols trapped in the arctic stratosphere reflecting back some of what sunlight reaches the high latitudes?


Along the edge of the arctic, Ross Hays who worked for CNN and then NASA who last year posted from Antartica sent this note to me “They have me working in arctic Sweden until mid July. One of the Esrange staff members told me that so far Kiruna had had the coldest June in 150 years!”
