By Dr. Roy Spencer
The Version 5.6 global average lower tropospheric temperature (LT) anomaly for July, 2013 is +0.17 deg. C (click for large version):
The global, hemispheric, and tropical LT anomalies from the 30-year (1981-2010) average for the last 19 months are:

2013 7 +0.174 +0.134 +0.215 +0.077
Note: In the previous version (v5.5, still provided due to contract with NCDC) the temps are slightly cooler, probably due to the uncorrected diurnal drift of NOAA-18. Recall in v5.6 we include METOP-A and NOAA-19, and since June they are the only two satellites in the v5.6 dataset whereas v5.5 does not include METOP-A and NOAA-19.

Global climate trend since Nov. 16, 1978: +0.14 C per decade
July temperatures (preliminary)
Global composite temp.: +0.17 C (about 0.31 degrees Fahrenheit) above 30-year average for July.
Northern Hemisphere: +0.13 C (about 0.23 degrees Fahrenheit) above 30-year average for July.
Southern Hemisphere: +0.22 C (about 0.40 degrees Fahrenheit) above 30-year average for July.
Tropics: +0.08 C (about 0.14 degrees Fahrenheit) above 30-year average for July.
May temperatures (revised):
Global Composite: +0.30 C above 30-year average
Northern Hemisphere: +0.33 C above 30-year average
Southern Hemisphere: +0.26 C above 30-year average
Tropics: +0.22 C above 30-year average
(All temperature anomalies are based on a 30-year average (1981-2010) for the month reported.)
Notes on data released August 5, 2013:
Temperatures in the tropics cooled to near seasonal norms in July, said Dr. John Christy, a professor of atmospheric science and director of the Earth System Science Center (ESSC) at The University of Alabama in Huntsville.
Compared to seasonal norms, during July the coldest area on the globe was off the coast of East Antarctica near the Ross Sea, where the average temperature was as much as 3.89 C (about 6.99 degrees Fahrenheit) cooler than the Antarctic’s winter seasonal norms. Compared to seasonal norms, the “warmest” area on the globe in July was off the coast of Chile in the South Pacific Ocean, where temperatures were as much as 2.31 C (about 4.16 degrees Fahrenheit) warmer than seasonal norms.
Archived color maps of local temperature anomalies are available on-line at:
As part of an ongoing joint project between UAHuntsville, NOAA and NASA, Christy and Dr. Roy Spencer, an ESSC principal scientist, use data gathered by advanced microwave sounding units on NOAA, NASA and EUMETSAT satellites to get accurate temperature readings for almost all regions of the Earth. This includes remote desert, ocean and rain forest areas where reliable climate data are not otherwise available.
The satellite-based instruments measure the temperature of the atmosphere from the surface up to an altitude of about eight kilometers above sea level. Once the monthly temperature data is collected and processed, it is placed in a “public” computer file for immediate access by atmospheric scientists in the U.S. and abroad.
Neither Christy nor Spencer receives any research support or funding from oil, coal or industrial companies or organizations, or from any private or special interest groups. All of their climate research funding comes from federal and state grants or contracts.

Re NikFrom NYC
Well no wonder AGWers see a continued rising of temperatures! It’s blurry! They need glasses!!!!
Full analyses of all surface and satellite datasets are updated monthly here.

I think you meant ‘Global Temperature Anomaly significantly down’. Given the critics that like to pounce on any error you make as if it is proof of your nefarious intent….
According to AGWers, there is no down trend as long as most of the data points are above a 30 year average. Has to do with that blurry thingy. And I am not being sarcastic.

….. obviously it’s an alien deep ocean heat-sucking spider crab. Trenberth was right after all.
We are all doomed, hold your breath and cancel sporting events…..too much breathing. CO2 is taking over the planet, what’s that noise? oh no, it’s here aggggggggggggggggggggh
It snowed in Southern Brazil and Paraguy with record cold temps there. 20% of the sugar can was wiped out. How is S America normal to above normal? OK, monthly average, but this surprises me.
“How is S America normal to above normal? OK, monthly average, but this surprises me.”
Averages are useless things when it comes to climate. It can be “below average” over 80 percent of some area but a great deal above average in a small local area that skews the “average” for the entire region. So most of the region can be normal or a degree or two below normal but one part of the region can be 10 degrees above normal and suddenly the entire region gets labeled as warmer than normal when it wasn’t.
I can’t even think of a good way to take Earth’s temperature.
So the 18 year trend-line is 0 deg Global Warming according to UAH.
Take it the way humans do. At each end.

it caught my attention. A 38 year old has not snowed in certain areas of southern Brazil. I know it’s average, but …
Incredibly cold summer here in southern Ontario Canada, highs around 21 degree C on a good day.
“Significantly” down?
It is above the 30 year averags.
It is above the Mar, April and May Anomalies.
The 30 year trend is still up, albeit an anemic 0.14 deg C / decade and maybe not significantly different from zero.
It is down from June, Jan and Feb.
I don’t get the significant part.
Since we humans and the price we pay for groceries are dependent on crops and livestock around the world, graphs & stats on crop yields would be a good proxy for verifying and showing the importance of any catastrophic temperature swings. Of course controlling for other factors impacting farming (e.g. diverting corn to ethanol) would need to be considered.

Same here south of Lake Erie, other than a week and a half or so in early July that was hot, we’ve had 70-80F highs this summer.
From my weather station:
Summary for period 6/1/2013 to 8/2/2013

Maximum 96.8 on 7/18/2013
Highest Minimum 76.1 on 7/19/2013

Wettest day 1.37 on 7/10/2013
High rain rate 36.24 day 6/5/2013
Rain days 33
Wind (mph):
Highest Gust 32.7 on 7/20/2013

This reminds me of the 70-80F summers of the 60’s and 70’s. If this trend holds, winter is going to suck.

“Significantly” down?
—————————-
Down on last month … If the same thing happened for July it would be below the 30 year average. But would that be significant. If you look at the plot you can see that not much is going on temperature-wise through out the duration of the records. ~+0.2 degC does not set alarm bells ringing around here, what about there ?
Down significantly again! Here are the headlines that have appeared at WUWT on UAH monthly temperature reports in the past 12 months. I’ve ranked them in order of the change in anomaly that is being reported, and omitted two where the data was presented with no “analysis” in the headline.
02/2013 -0.33 big drop in global temperature
07/2013 -0.12 significantly down
04/2013 -0.08 down significantly
11/2012 -0.05 down slightly
10/2012 -0.01 unchanged
03/2013 +0.01 unchanged
08/2012 +0.06 not much change
09/2012 +0.13 up slightly
06/2013 +0.22 up somewhat
01/2013 +0.30 up significantly, but other data doesn’t match.
Anyone spot any bias (intentional or otherwise) in these descriptions?

and if you look at the same plot on a warmist site, it would be an extreme catastrophe, a dangerous calamity or some other adjective with an overused preceding modifer meaning the exact opposite of the reality of the data.
I’ve posted the full sea surface temperature update today:

There’s an unusual warming event in the North Pacific in July that I’ll be reporting on hopefully tomorrow.
I have updated my graph:

None of these numbers gives any idea what the energy balance looks like – are we accumulating or shedding energy from the sun?

LOL… Wish I’d have had you in school.
I agree that the “significantly down” modifier is not a good choice of words.
Mid North Carolina was cold too. (It was 64F this morning) and we have had only a eight days of 90-92 F and one day at 95F so far this year. Nothing above 90F in the forecast either.
Ten years ago we had 17 days 90F and above in May, with five days at 95F and over (2 at 98F)
July 2004 had 24 days over 90F with seven days at 98F or above.
My white clover is still doing well and blooming instead of dying back as it usually does in summer.
