Tropics: +0.17 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 June 4, 2013:
Global average temperatures and the tropics continued a slow cooling drift in May, downward from a warm January, 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 May the coldest area on the globe was in northern Greenland, where the average temperature was as much as 3.75 C (about 6.7 degrees Fahrenheit) cooler than seasonal norms. Compared to seasonal norms, the “warmest” area on the globe in May was in the northern Siberia. Temperatures there were as much as 3.91 C (about 7.0 degrees Fahrenheit) warmer than seasonal norms for May.
Archived color maps of local temperature anomalies are available on-line at:

The processed temperature data is available on-line at:
vortex.nsstc.uah.edu/data/msu/t2lt/uahncdc.lt
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 and NASA 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.

My wife complained about last month’s cold nights, but since we’re in a + anomaly area, I can tell her she’s nuts and Dr. Spencer says so. 🙂
Except for Scandinavia & Siberia, latitudes above 60 degrees appear colder than normal. Isn’t CO2 supposed to warm the Arctic & Antarctic more than mid- & low latitudes?
I cannot imagine how cold it must have been in the old days. No matter how cold it gets, the anomaly is always positive. Beginning to think glaciers must reach the equator in July in order to get -0.1C
And for those interested, I posted the really early preliminary sea surface temperature anomalies for May last week.
http://bobtisdale.wordpress.com/2013/05/27/very-preliminary-may-2013-sea-surface-temperature-sst-update/
I checked this morning and there weren’t any major changes in the weekly data.
The full update will be up on Monday the 11th
In your first chart, 8 times out of 10 when their was a single spike in Global temperatures other was a sharp fall off in temps. Also I see connection to the economy with manufacturing with spikes and dips in global temps, when manufacturing was at full speed and dips when slowed.
The chill over northern Greenland, looping over to Alaska and westernmost Siberia seems significant, as usually most of the arctic is pink and red on these anomalies-maps. It is one reason I’m estimating high, on next fall’s minimum ice-cover. The DMI graph of temperatures above eighty degrees north has been below average for some time, as it heads up to the summer plateau of around 34 degrees (F) at the pole, and looking back at the past years graphs that site offers seems to show such low temperatures are not that common, and are associated with some of the colder years and more severe winters, such as back in the 1970’s.
The weak La Nina conditions off Peru don’t offer much hope of warming, although if the La Nina gets stronger we in New Hampshire might luck out, and exist in a locally mild bubble next winter. For some reason it when a warm El Nino first kicks in that we get our worst winters, unless the El Nino is super strong.
When was it that Hansen made his speech before congress, on the artificially hot floor (because they left the windows open in June.) ??? In 1987, 1988 and 1989 the temperatures were roughly at the same level they are this June, if not hotter. 26 years, and not a bit of warming. Hansen just looks worse and worse.
0.074C
Clearly, the planet is overheating.
I assume this increase is 100% accurate with no possibility of errors involved?
Here’s a link to a New York Times article from June 24, 1988, describing Hansen testifying before Congress, http://www.nytimes.com/1988/06/24/us/global-warming-has-begun-expert-tells-senate.html
“If the current pace of the buildup of these gases continues, the effect is likely to be a warming of 3 to 9 degrees Fahrenheit from the year 2025 to 2050, according to these projections. This rise in temperature is not expected to be uniform around the globe but to be greater in the higher latitudes, reaching as much as 20 degrees, and lower at the Equator.”
Roy:
Lookling at the globe figure I can’t help thinking that the resolution is worse along the equator and better towards the poles.
Any reason for this? And does it have eny implications for the measurments?
Anthony, you had a post earlier that March and April were the 2nd coldest beginning to a meteorological spring on the record. In the article you mentioned that #1, 1975 had a warm May, and, if May was cold this year it could take the title of ‘coldest meteorological spring’.
Are you able to provide an update?
Robert Wykoff, don’t know how old you are, but as a younger teen in the late 70s I can confirm it was cold. Cold. At least here…. we had cold winters with tons of snow and cool summers. Most of my childhood vacations include camping on cold summer nights in British Columbia and Washington State. More than once our street in Calgary was snowed in during the 70s, which has not happened since.
Then again, it was the beginning of a new ice age, apparently, although the people who actually remember the hype are now being told there was no such hype by people who either are too young to remember or have an agenda.
I am in rural Montana and it was high today of 55F and tonight 40F. June 4, 2013
@ur momisugly CodeTech – and I don’t know how old you are… oh hey wait, you said you were a kid in the late 70s and didn’t have snow since then in Calgary (sic!). Now I am a bit of a 70s kid myself and I remember there were winter olympics in 1988, you know…

Old days? Are those before or after I was was born?
I remember one cold winter in southern NH when the temperature warmed up some and I went out to check my Taylor Max/Min thermometer on a tree. There wasn’t a breeze, so I felt rather comfortable until I saw it was 12°F (-11°C or so). That year also froze in the Cape Cod Islands, lessee. Ah, this might be about what I had in mind, http://www.csmonitor.com/1981/0116/011642.html is from mid-January 1981.
I don’t know offhand how often the Atlantic freezes from Nantucket to the mainland, but’s not very often. In January 2013 “North shore beaches were iced over out several hundred yards.” I think most years it doesn’t freeze.
The NCDC says the mean minimum temperature in Concord NH for January 1981 was 0.5. Cold! Coldest night -21^deg;F. The year before had a mean minimum of 11.8, but February was colder. Hmm, December was colder too, 80/81 was a cold winter.
2012 was really warm – January had a mean minimum of 16.7°F. Maybe I should look into that period a bit more.
Seems the global temp is out of place.
Should it not be increasing this time of year on average?
Couldn’t be due to pushing a whole bunch of ice in the N Atlantic last year from the equivalent of an Arctic Hurricane, could it?
Hummmmmm>
Matt – the opening ceremonies for the 1988 Olympics were held in McMahon stadium – where they had to truck in white sand to make it look like snow, however there was plenty of real snow and cold later on for the Ski jumping events at Canada Olympic park.

Think “difference-from-average-temperature-at-this-site-on-this-date” rather than local-temperature-at-this-spot-on-this-date.
Make sense now?
Here in cityfied Wyoming the forecast high for tomorrow is 55F with a low tomorrow nigh of 41F. June 5, 2013 Feels good, I love it.
The data must be wrong because there was no chance the midwest…Illinois, Indiana, Wisconsin etc.had a positive anomaly. It has been a cold spring.

The weak La Nina conditions off Peru don’t offer much hope of warming…
And I like how your blog puts it more bluntly then this post: UAH GRAPH SHOWS TEMPERATURES SINKING WORLDWIDE.
But, lol, there’s no hope of warming? I thought warming was the enemy, and would be the cause of our ruin… unless we reformed our ways and returned to peaceful stone age style living. Now, with a snowy June over many parts of the globe do we just wish for warmth? No, cold is what we should want, to keep us save from the impending doom that the fear mongering Chicken Littles keep crying wolf about.
@CodeTech:
I’ll enter the Northwest old timers’ memory Olympics with my recollections of this record-setting night:
Washington –48 –44 Dec. 30, 1968 Mazama & Winthrop 2,120; 1,765
I was in NE Oregon, where we only hit -35 F, but that was at 1700 feet. Carried my buddy’s little Japanese sports car indoors.

@Gary Young Hladik
“I can tell her she’s nuts and Dr. Spencer says so”
You can, but I hope you are not stupid enough to try.
@Matt and CodeTech: I was at the 1988 Winter Olympics. Dust was a problem for some events such as the bob sled. There was not a lot of snow on the ground around Calgary at that time. I lived in Lethbridge Alberta in 1966-67 and I remember lots of snow then. In fact my twin brother and I were punished for hiking home from school on the snow mounds created in the middle of the streets from the plows. We had not gone to school the day before because of the snow so had not been informed to not do that, while the rest of the class was. The one and only time in my life I was physically punished at school and it was not justified.
I have exclusive pictures that I took of the Jamaican Bob Sled Team, inspecting the run before the event. Also, the only trained hockey players game (no pros allowed until the 1992 games) I ever have seen in my life involved the East Germans and some other team. I haven’t seen a pro hockey game before or since, except on TV.
And lastly, around the early 1980’s I was considering moving south, emigrating to the USA because of my considerations for my future family and the advancing glaciers I had been assured were sure to come.
