Er …. call me a dope , but we’ve had June already and now seem to have it again. I was waiting for July, is this some kind of June re adjustment? Actually they are both the same. What gives Dr Spencer ?
Thanks

well its still blinkin cold here! UK East coast.

Not wishing to be picky but you already posted this here http://wattsupwiththat.com/2012/07/06/uah-global-temperature-for-june-2012-up-slightly/

Whoops – just realised it was posted twice in this item and the headline has a different temperature to the body

Not from Dr. Spencer.
Looks like an error here?

Title — “up 0.29 °C” — is inaccurate. Previous month was 0.29 °C, so this month’s reading (0.37 °C) is up 0.08 °C.

And for those looking for the preliminary sea surface temperature update for July 2012, here’s the monthly link:
http://bobtisdale.wordpress.com/2012/07/30/preliminary-july-2012-sea-surface-temperature-anomaly-update/
That post also includes updates to the comparisons of NINO3.4 and NINO1+2 sea surface temperatures for this year compared to the evolution of “similar” El Niño events.
Also, if you have any El Niño/La Niña-related questions that you’d like answered in my upcoming book, please leave them on the thread of this post:

Large oscillations in the last two years may indicate possible onset of the sensors’ instability.

No summer in Norway this year. The coldest and wettest June/July I remember.

Cold and rainy in Sweden to. Reminds me of the wet and cold summers in mid 60th.

The weatherman on the tv here in the UK said “It’ll feel more like February than August” tomorrow. Most of the summer has been like this, just as it has been with the Scandinavians.

Let’s wait for the full year’s data and then judge what’s happening. I believe the US had quite a warm July this year.

No, really – why does this post exist?
It is a repost of a July 6 WUWT article. It is double posted here. And the headline is wrong.
Mods?

[REPLY: I’ve been getting much the same impression. You are quick to denigrate the qualifications of people you know nothing about, failed to look at the surface station web site, offered some-what valid criticisms and then harped on them… and people who are NOT trolls do NOT invent a screen name that looks like a real name. In the event that you even think about insisting that your name really is “William Roberts”, let me suggest that your initials are in fact CRM and that the numerals 8-4-3-7 should have some significance for you. Your participation here can be valuable, so please drop the attitude. -REP]
Interesting, so is blackmail standard operating procedure for WUWT moderation? How revolting. A quick scrutinizing of the policy reveals that using my real name is not necessary. It is not a requirement for me to be posting here. In fact, I see numerous contributions by usernames that are not real names. My aggressive questioning of the methods is not precluded by you not knowing my real name, by your own website policy. After all, the peer review process is anonymous. Are you suggesting only people who aren’t interested in using their real names have no valuable contributions? Why are you threatening to reveal my identity [SNIP: No one has to know that much. -REP] for offering valid criticisms that any peer reviewer would make? And for the record, William is my grandfather’s name, and Robert is my father’s name.
[REPLY: Good. Now that I have your attention, the topic is trollish behavior. My description stands. You will also note from our site policy that trollish commenters using public positions and public funds are not guaranteed anonymity. You have a more than adequate and relevant professional record and could make a valuable contribution here. Instead you choose to be hostile, arrogant and petulant. You spoil intelligent suggestions by jumping up and down insisting that they are all of paramount importance. There are a large number of commenters here with far better qualifications than yours who don’t behave so. So, once again, drop the attitude and contribute or take your act somewhere it will be appreciated. -REP]

I agree this post is a mess, something’s wrong.
Looking at the daily AMSU curve for 14000 ft, July should be below the same month last year, not above.

It is if you wish to be taken seriously.
> In fact, I see numerous contributions by usernames that are not real names.
And we don’t take them as seriously as we would if they used their real names.

You aggressive questioning while hiding behind a pseudonym marks you as an Anonymous Coward.
There are several other blogs that seem to revel in being obnoxious, feel free to seek out your kindred spirits.

Bob tisdale says that this years el nino is comparable to 2009/2010 at the same month of july.
http://wattsupwiththat.com/reference-pages/enso/
It looks much lower to me in july,this years el nino is just over 0.5 while 2009/2010 was at about 1.00.

The anomaly increases in the NH summer and decreases in the NH winter. SH and tropics show no real trend or seasonality. This trend seems to date to around 2000, reversing the opposite trend from the 1970s.
Which is the opposite of what GHG theory predicts. It predicts increasingly warmer winters.
This clearly points to decreased NH clouds from around 2000 being the main climate driver. And by implication increased clouds causing the post 1970s warming.
Likely cause, the shutdown of much of the aerosol polluting industry in Russia around the time of their 1998 financial crisis.
Dr Spencer, has anyone analyse daytime versus night time trends in the satellite record. I’d expect to see the same pattern of increases in the anomaly during the day and decreases at night. Also contrary to GHG warming theory.
