Hottest May On Record- NOAA and NASA
Posted by Dan Satterfield
Hottest May on record. From NCDC-NOAA
NOAA and NASA both do an independent global temp analysis. NASA released their data a couple of days ago for May. The National Climate Data Center released their May data today. The extreme warmth in the northern latitudes is expected with warming from increased greenhouse gases. Northern areas will warm faster than areas further south for several reasons, among them the ice albedo feedback.
Both indicate that May 2010 was the warmest month globally since reliable records began in 1880. This comes with an unusually quiet sun that is just now beginning to become active again. (This solar cycle will peak in 2013 and is forecasted to be fairly mild).
The NASA data had May at 6.3C above the mean (1951-1980). Here below is the NASA data:

Divide by 100 to get changes in degrees Celsius (deg-C).
Multiply that result by 1.8(=9/5) to get changes in degrees Fahrenheit (deg-F).
Best estimate for absolute global mean for 1951-1980 is 14.0 deg-C or 57.2 deg-F,
so add that to the temperature change if you want to use an absolute scale
(this note applies to global annual means only, J-D and D-N !)
Example -- Table Value : 40
change : 0.40 deg-C or 0.72 deg-F
abs. scale if global annual mean : 14.40 deg-C or 57.92 deg-F
Arctic sea ice also continues to melt at a faster rate than in the record low year of 2007. Too soon to say if a new record low will be set this September at the end of the summer melt. It will likely be close.
