UAH Global Temperature Update for August, 2012: +0.34 deg. C
By Dr. Roy Spencer
The global average lower tropospheric temperature anomaly for August (+0.34 °C) was up from July 2012 (+0.28 °C):
Here are the monthly departures from the 30-year (1981-2010) average:
YR MON GLOBAL NH SH TROPICS
2012 1 -0.09 -0.06 -0.12 -0.13
2012 2 -0.11 -0.01 -0.21 -0.27
2012 3 +0.11 +0.13 +0.10 -0.10
2012 4 +0.30 +0.41 +0.19 -0.12
2012 5 +0.29 +0.44 +0.14 +0.03
2012 6 +0.37 +0.54 +0.20 +0.14
2012 7 +0.28 +0.45 +0.11 +0.33
2012 8 +0.34 +0.38 +0.31 +0.26
As a reminder, the most common reason for large month-to-month swings in global average temperature anomalies (departures from normal) is small fluctuations in the rate of convective overturning of the troposphere, discussed here.

I did miss that. I usually don’t read every comment, especially late on Friday night when I’m tired from the week. But when I’m scrolling through the comments I stop on a few names. Bill Illis is one of them. That’s why I saw his.
So much for it being the hottest July on record, just shows you how much NOAA and other government agencies are lying to you.
Eric, there is more to the world than the U.S. (it makes up less than 2%).
Reading these comments I cans see why there’s such a problem in perception. It’s not 1/3 of a degree Celsius of increase over a flat line (as depicted), it’s a 1/3 of a degree increase over a 13 month average. If that 13 month average is rising, which I’m guessing it is, then we have global warming. One other thing… I’ve always wondered.. How do you increase greenhouse gasses in the atmosphere and NOT have global warming? Is that Republican math? Watts up with that?

“Reading these comments…”
It appears that John P hasn’t been reading much of anything. Global warming has been happening since the end of the Little Ice Age, at a steady rate. The rising temperature trend has been the same whether CO2 was low or high. If John P was a thinking person, he would conclude that CO2 has very little effect on temperature.
Well I think the good Dr Roy has maybe fallen off the wagon; who knows if Professor Christy did too.
The most notable thing about Dr Roy’s latest information, is that those blokes no longer declare the entertainment value of their fourth degree polynomial fit.
Are you saying you have found an effect Roy, or did you encounter a big flash of light while on the road ?

Re: polynomial fit and reference points for anomalies\
The purpose of any curve or line is to indicate trends……”””””
The hell you say !. I always thought the purpose of any curve or line was to show the value of the dependent variable over some range of the independent variable. If you say it doesn’t do that, then don’t draw the line, and suggest it reports facts not in evidence.
Mother Gaia always knows what the trends are; she isn’t going to tell us till it’s done with.

“I’ve always wondered.. How do you increase greenhouse gasses in the atmosphere and NOT have global warming?”
===================================================
It is very easy, John. For example, if “greenhouse gasses” can not physically cause warming, their increase in the atmosphere can not cause “global warming”.
I understand that the term “greenhouse gasses” suggest warming, but historically some scientists like 150-100 years ago just thought that they can warm and never proved that. They just (mistakenly) thought that real greenhouses got warmed because of “back radiation” from the glass and since knew that some gasses produce back radiation, they concluded that this back radiation from certain gasses must warm the surface and called them therefore “greenhouse gasses”.
Later in 1909 a well known scientists demonstrated that this “back radiation” does not work and the “greenhouse gasses” hypothesis died scientifically. However, this scientific dead body was dug out by some clever persons later in 1970s and now we have a scientific zombie walking around and scaring people.

“And Sorry guys. It does need the disclaimer. As someone pointed out, this polynomial would imply that it was warmer before 1979 when in fact it was cooler.”
I disagree with you Bill – there was global cooling from about 1940 to 1975, so it was WARMER before 1979.
Check the surface temperature (ST) records. The warmest USA temperatures in the data record were in the 1930’s during the Dust Bowl.
Not sure the global surface temperature records are worth much due to lack of quality control – even the USA ST record shows a warming bias due to poor siting, urban growth, etc.
BTW, I like the polynomial – it shows a half-period of about 30 years, for a full-period of about 60 years, similar to the PDO. Global cooling should be evident by about 2020-2030, as I wrote in an article in 2002.
Let’s compare my (our) prediction to the IPCC’s prediction of catastrophic global warming, which should be evident by now, but is NOT !
