July Temperatures Near Detroit

SEARCH BLOG: GLOBAL WARMING

It should be pretty obvious to those living in Michigan that "global warming," like Joe Black, has taken another "holiday." July continued the below normal temperatures for this Detroit suburb. In fact, year-to-date, there have been only two 90° degree days... one in June and one in July.

That's not to say there won't be anymore 90° days... August has begun with some near-90° days... but their frequency is well below "average." We would have to experience another 10 days of 90°+ temperatures... just to reach the "on average" point [see below].

If we go back 8 years, we read this from NOAA:

*********
JUNE 2000
*********

...ONLY 90 DEGREE OR BETTER DAY RECORDED THE ENTIRE SUMMER...
...20TH WETTEST JUNE ON RECORD...
...WET SPRING CONTINUES INTO EARLY SUMMER...
...SEVERE WEATHER FREQUENCY PICKS UP DURING THE MONTH... 

SHOWERS AND THUNDERSTORMS VISITED THE AREA FREQUENTLY, ESPECIALLY AFTER
THE 10TH, AS CLASHING AIR MASSES MET OVER THE REGION. IN RESPONSE TO
THE FREQUENT AIR MASS CHANGE, TEMPERATURES PIVOTED FROM ABOVE NORMAL
TO BELOW NORMAL AND THUS, BREAKS FROM THE HEAT AND HUMIDITY CAME
REGULARLY. NO RECORD HIGHS OR LOWS WERE SET DURING THE MONTH BUT A
91 DEGREE READING ON THE 10TH WAS THE ONLY 90 DEGREE OR BETTER
TEMPERATURE REACHED DURING THE ENTIRE SUMMER. ON AVERAGE, WE SEE 
ABOUT 12 DAYS OF 90 DEGREES OR BETTER IN A TYPICAL SUMMER. JUNE'S
ABOVE NORMAL TEMPERATURE DEPARTURE WAS DIRECTLY RELATED TO ABOVE 
NORMAL NIGHTTIME LOWS, RATHER THAN DAYTIME HIGHS, WHICH ACTUALLY 
AVERAGED JUST SLIGHTLY BELOW NORMAL.  [urban effect?]

It's difficult to reconstruct the annual summaries for the decade in this area... some are in different formats and 2006 summary appears to be missing or archived in another location than the other years. Some summers are a bit hotter and some cool. Michigan seems to reflect the national pattern.

Generally, there is virtually no correlation between the frequency of high temperatures and atmospheric CO2. There is virtually no correlation between between average temperature and any measured increase in atmospheric CO2. There only appears to be a correlation between political hot air and CO2.

Where's the global warming? Not here.
