[Updated] UAH, straight from the source, Dr. Roy Spencer who announced it on his blog today.
The was a lot of speculation last year that our global temperature would recover from the huge drops last spring. While there has been some recovery, the overall global temperature trend since 1999 has been the subject of much debate. What is not debatable is that the current global temperature anomaly, as determined by a leading authority on global satellite temperature measurements, says we have no departure from “normal” this month. Given the U.S. Senate is about to vote upon the most complex and costly plan to regulate greenhouse gases, while the EPA suppresses earlier versions of the chart shown below from a senior analyst, this should give some pause to those who are rational thinkers. For those that see only dogma, I expect this will be greeted with jeers. – Anthony
June 2009 Global Temperature Anomaly Update: 0.00 deg. C
Dr. Roy Spencer
July 3rd, 2009
YR MON GLOBE NH SH TROPICS
2009 1 0.304 0.443 0.165 -0.036
2009 2 0.347 0.678 0.016 0.051
2009 3 0.206 0.310 0.103 -0.149
2009 4 0.090 0.124 0.056 -0.014
2009 5 0.045 0.046 0.044 -0.166
2009 6 0.001 0.032 -0.030 -0.003
June 2009 saw another — albeit small — drop in the global average temperature anomaly, from +0.04 deg. C in May to 0.00 deg. C in June, with the coolest anomaly (-0.03 deg. C) in the Tropics. The decadal temperature trend for the period December 1978 through June 2009 remains at +0.13 deg. C per decade.
NOTE: A reminder for those who are monitoring the daily progress of global-average temperatures here:
(1) Only use channel 5 (”ch05″), which is what we use for the lower troposphere and middle troposphere temperature products.
(2) Compare the current month to the same calendar month from the previous year (which is already plotted for you).
(3) The progress of daily temperatures (the current month versus the same calendar month from one year ago) should only be used as a rough guide for how the current month is shaping up because they come from the AMSU instrument on the NOAA-15 satellite, which has a substantial diurnal drift in the local time of the orbit. Our ‘official’ results presented above, in contrast, are from AMSU on NASA’s Aqua satellite, which carries extra fuel to keep it in a stable orbit. Therefore, there is no diurnal drift adjustment needed in our official product.

Thanks for the info.

I’m sure this will translate into something with the words “faster than expected” in it at Copenhagen.
An important note:
Generally, people seem to refer to the UAH data here:
http://vortex.nsstc.uah.edu/data/msu/t2lt/uahncdc.lt
However, you will notice that Roy always reports in 3 digits, rather than two. For consistency (not that it makes a difference) these numbers should be used:
http://vortex.nsstc.uah.edu/data/msu/t2lt/tltglhmam_5.2
They are directly comparable (this is where Spencer’s values eventually show up) and they also match the digits used by RSS (3)
But it’s a minor point.
Here is a question.
What is used to determine the height of a temperature measurement on the satellites?
Not much warming to show for 30 years of rising CO2.
1998 was the poster child for the AGW crowd. Now they want to minimize it. Somehow they want to have it emphasized to show 20th century warming, but minimized to discount the recent cooling.
It is almost fun to watch, except that I know that global cooling will cause a lot more pain than global warming ever did.
Can’t wait for the July data.
As our Prime [minister] Gordon Brown would point out, that’s still a temperature increase of 0.0
Neat work, Anthony. You sure do stay on top of the latest and most accurate findings. And thanks to Dr. Roy Spencer.
So the catastrophic global warming that furrows the sweated brow of our politicians in the House and soon in the Senate is cooking right along at…0. Yessir, Mr. Malarkey, we must do something to stop this runaway train screaming past us on the way to carbon Armageddon at the speed of…0. I predict the cap and trade system will just make tons of money at a market interest rate of…0. I have got to buy me some of these! No one can pass up that interest rate. Why, it beats the hell out of our current -25% all to hell and gone! Why, with the $1000 I lost last year in my retirement account, I will be directing my financial advisor in invest in stocks with an interest rate of…0. Finally, anyone who votes for any scheme even remotely related to such a bright future based on runaway global warming of…0, should receive exactly…0 votes in his or her next election.
Good job, Pamela. I needed a good smile this morning.
darn it…
no sun spots
the ice is melting too slow
the temp is not dropping
the hell with it, we are going to tax you anyway

From the above, it looks like “the coolest anomaly (-0.03 deg. C)” was in the Southern Hemisphere (SH?), not the Tropics, which was only -0.003 deg. C
In the UK we’ve just had a couple of hot summery weeks (looks like its coming to an end now). Given the met offices’ recent predictions for 2080 I do not believe this will make an appearance in any MSN publication.

Good question. I found this the other day:
http://books.google.co.uk/books?id=DcXZF9vogtkC&pg=PA123&lpg=PA123&dq=sea+level+altimetry&source=bl&ots=Ygfn1anHnM&sig=fx_C7fFySsx1XGOUNAfKmLb_jKM&hl=en&ei=-6dMSr_zNs-TjAeKo6yzBQ&sa=X&oi=book_result&ct=result&resnum=6
All sorts of things have to be allowed for to get correct heights.
Does anyone else think John Christy and Dr Roy Spencer are being playful here?
0.001C
Maybe the calc came out at -0.001C but they don’t want us hopping and hooting just yet. perhaps it’s more fun to hear the warmista saying “it’s still positive”.
Wonder what next month will bring. And what RSS will say.
Either way, not many signs of Joe Romm and Jim Hansen’s super el nino yet.
Aron predicts the UK summer will be mostly a wash out like it was last year.
M White… (12:28:00) So you mean everything above 20C is hot??? Note: Luton N of London
never “hotter” than 28C (SMALL airport…) Heathrow W outskirts dito, 30-31C (big AIRPORT…)[4 consecutive days] August 2003 is just a memory now….SO
since the 1930’s and 1940’s, all that asphalting of the planet has made heatwave
max temps to drop 5-6C, WHEREAS average temps are up 1C…The warmest
anomalies seem to be at 500m up to 3000m ASL…
The data is obviousy nonsense. Temperatures are soaring in the UK where we have just experienced our warmest June in the UK since…errr… 2007

What’s the base period for this anomaly? I followed the link to Spencer’s page, but it didn’t say either.
Here is the follow up documents of the meeting between Senator Fielding and the Minister for the Climate Change and Water, Penny Wong.

Looks like the AGWers don’t know or just can’t answer simple questions anymore…
Cue the Talking Heading music … “I’m on the road to nowhere”

It says 1979-1998
This reminded me of that Nature article from last year:
http://www.nature.com/nature/journal/v453/n7191/full/453043a.html
“Climate change is often viewed as a phenomenon that will develop in the coming century. But its effects are already being seen, and the Intergovernmental Panel on Climate Change recently projected that, even in the next 20 years, the global climate will warm by around 0.”
‘Warm by around zero’, got it. I don’t recall the IPCC projecting any such thing, but they must have, because its happening already! Its warming by around zero sooner than anyone expected…
