Global carbon dioxide is up! But global temperatures are not see this.
Same as in Al Gore’s polar ice cores (he forgot to tell you): carbon dioxide FOLLOWS global temperature.

“The average temperature in January 2008 was 30.5 F. This was -0.3 F cooler than the 1901-2000 (20th century) average, the 49th coolest January in 114 years. The temperature trend for the period of record (1895 to present) is 0.1 degrees Fahrenheit per decade.”
For those that have been harping about my “2nd coldest in 15 years” headline, it appears that NCDC has that one beat with “the 49th coolest January in 114 years”.
Of course, we’ve had several prior years where the monthly average dipped below the 1901-2000 average, so this is nothing of real value, but I thought it was interesting to point out NCDC’s choice of assigning a rank to the month.
This graph is using the USHCN2 data set, the graph was generated by NCDC from the engine at this link. The long term trend is unchanged. It would take several years of below average temperatures for the 1901-2000 trend to start dropping, but since Joe Bastardi points out that he sees a “regime change“, that may be a possibility, at least for USHCN (United States) data.
