Not global but perhaps relevant and interesting.
From the Cleveland Plain Dealer, http://www.cleveland.com:
"But more than 1,100 daily record low temperatures were broken in July nationwide, according to figures at the National Climatic Data Center reported today by AccuWeather. An additional 1,200 stations tied records."

I guess what really interests me... is what then caused the huge cooling trend in Minneapolis from 1835-1875?
And wouldn't even smaller solar variability against the temp record sort of beg the question that very slight solar variations can have even bigger temperature impacts than previously thought?

glc. (1) It's my understanding that the peak sunspot count occurred in ~1958.
glc. (2) However, you look at it solar activity didn't peak any later than ~1990/91.
Mmmm. Now that is a rather a U turn, are you are member of Browns government. Interestingly enough, the two versions of your answer are appx 30 yrs apart. Now we have had lots of discussion on 30 yr cycles but none of them seem to include CO something or other.
Must say every warmest got annoyed with my last post. Must be getting close to the truth.

The peak sunspot count was in 1958, while the smoothed sunspot count peaked in ~1991. To clarify: Solar Cycle 19 which peaked in 1958 had the highest sunspot count while SC 18 and SC 20 did not have particularly high counts. The highest smoothed count was during cycles 21 & 22. Cycle 22 peaked in 1990/91 and ended in 1996. There is no U-turn. If you are unsure about sunspot counts and how they are categorised don't hesitate to ask.

Regarding the sunspots you can´t just look at the absolute maximum. You need to look at the activity of the cycles. If you start from 1945 and go forward to 2005, you have under these 60 years a total of 20 years with an SSN value over 100. And you had only 2½ year with an SSN under 10. Now since 2007 we have now had 22 month (to Jan 2009, probably 28 month to July 2009) with an SSN under 10. And this time it is in a row. The sun is quiet and cooler now. But for 60 years the sun was heating up the oceans.
Now regarding the warming of the oceans there must be a lag time. How long I don´t know. But since 2007 the sun has been quiet. But before that the heat was on.

very surprised with a july UAH anomaly of +.4.
especially with the bulk of NA in a freakish cool spell. I checked out the UAH figures and saw that the Southern hemisphere was a whopping +.609, warmest it has been since feb 98, 2nd warmest anomaly in SH since the satellite era.
What the heck? why did the SH spike so highly? why haven't there been any news stories on it (have to be a freakishly warm spell for winter in the SH)?
does anybody have any web sites with an anomaly map for july? I would love to see the distribution. is it possible we are looking at a transitional error? (I read somewhere that we were about to switch channels? on the satellite data)

Antarctica was particularly "warm" (relatively speaking). This explains some of the SH spike. But there was general warming over the oceans which also boosted the UAH figure. The oceans represent ~70% of the surface so will be far more influential on a global scale than, say, North America.

Where does John Christy keep the global maps now? The old link climate.uah.edu/still shows December.

Heh, anyone else wonder if maybe it's just time for the southern hemisphere to warm and the northern to cool?

That has been the pattern over the last ~100 years.

somebody correct me if I am wrong. as it is deep winter in the SH, that means the 'extra' heat pretty much came -out- of the oceans? are our oceans in some sort of cyclical dumping of heat? does that helps explain the anomalous warming of 98-2005? our oceans had a heat surplus, which the dumped into the atmosphere over that period, and now the SH ocean is similarly dumping heat now? and as the heat is dissipated from the oceans, our climate will return to a more 'normal' pattern?
also, does anybody else think that the media are ignoring the "global temp" warmth this past month because they would be met with ridicule and scorn from shivering North Americans?

Nah, it's probably not newsworthy though because it would ALSO draw attention to the fact that it hasn't warmed in a decade. HOWEVER, they did barf up some garbage to go along with Mann's rediscovery of the medieval warm period ...er uh...I mean discovery that man is causing more hurricanes but that there were just as many 1000 years ago. As for the NH/SH temperatures, I was just being sarcastic above. The warming cycles just switch back and forth between warming and cooling the hemispheres. Its just that when the northern hemisphere warms or cools it has more of an affect than the southern. When the NH warms, the world warms more. When the NH cools, the world cools more.

Anyone know what has happened to NOAA July weather data. I go to the normal web address, and all I get is "Page not found". Is it me, or is NOAA just late?
