October 2008 Update on Global Temperature – GISS
Posted by The Diatribe Guy on October 9, 2008
Stating in advance I may not get this whole post done immediately, I will nonetheless press on and get up what I can. If need be, I will come back and edit/update as necessary.
The information is found ,a href=http://data.giss.nasa.gov/gistemp/tabledata/GLB.Ts+dSST.txt>here.
*The September anomaly is 49 (in terms of 0.01 degree Celsius).
HISTORICAL COMPARISON OF THE SINGLE DATA POINT
*It is 0.01 degrees cooler than August 2008
*It is 0.01 degrees cooler than September 2007
*It is the coolest September anomaly since 2004
*5th warmest (125th coolest) September anomaly out of 129 data points since 1880
*81st warmest (1,465th coolest) anomaly out of the total 1,545 monthly observations
*The latest 12-month average is now 41.6, wich is the coolest 12-month stretch since the period ending September 2001. If you are anal enough to look back at the previous average, you’ll remember that the last 12-month average was 40.8. So, if it was 40.8 last month, and is 41.6 this month, and this month’s average is the coolest since September 2001, how can this be? Welcome to our good friend, Mr. GISS Adjustment. Some of the previous month’s values were rather largely adjusted upward from the summer months. The average ending August month end has now increased from 40.8 to 41.8.
*This is the 6th consecutive month with a year-over-year anomaly decline
*13 of the last 14 months show a year-over-year anomaly decline
