Juggling the Arctic

According to DMI, July was probably the coldest on record north of 80N.

Daily mean temperatures for the Arctic area north of the 80th northern parallel, plotted with daily climate values calculated from the period 1958-2002.

JAXA showed that July had the slowest Arctic ice melt on record.

Webcams and buoy data show us that this “summer” has been frigid near the north pole.


NSIDC reported that July had “cool, stormy weather” in the Arctic.

GISS is undaunted by these facts, and has released their July maps showing most of the region north of 80N above the 1958-2002 mean.

How did they accomplish this feat? But having little or no data north of 80N.GISS has algorithms to make up extrapolate data across vast distances with no data. In the image below, the black areas represent “missing data”

GISS also shows all of Greenland as above normal for July, while NOAA anomaly maps show the Greenland Ice Sheet far below normal.

Once again, GISS has little or no data on the ice sheet.

Dr. Hansen (far and away the most highly respected climatologist in the world) at GISS wrote this earlier in the year:

the 12-month running mean global temperature in the GISS analysis has reached a new record in 2010…. GISS analysis yields 2005 as the warmest calendar year, while the HadCRUT analysis has 1998 as the warmest year. The main factor is our inclusion of estimated temperature change for the Arctic region.


Conclusion : GISS has determined that 2010 is the hottest year on record, based on their belief that the Arctic has experienced anomalously warm Arctic temperatures. All available data from other sources shows us that July was anomalously cold in the Arctic.

GISS Arctic temperatures are incorrect, and as a result their global temperature rankings are highly suspect.
