July 2008 Satellite Measured Temperature Anomalies

Here are the July 2008 global temperature anomalies as measured by satellite using microwave soundings. The data is provided by Remote Sensing Systems (RSS) using MSU and AMSU data. The below image shows the July temperature anomalies across the globe for the lower troposphere in degrees Kelvin. The reds and yellows indicate warmer-than-normal temperatures during the month of July, while the blues indicate cooler-than-normal conditions.

As you can see, the warmest temperatures compared to normal were found over central South America. Other above-normal areas included Atlantic Canada and eastern Russia.

Temperatures were clearly below-normal over Alaska and the Yukon Territory, aso over the far southern oceans.

Here are some specific numbers (temperature anomalies) for July.....

Global land and sea combined: +0.147 degrees Kelvin, making it the warmest month compared to normal since October of 2007, but still cooler than the past three July's.
Northern hemisphere: +0.258 K
Southern hemisphere: +0.031 K
Continental U.S.: +0.340 K

From The Desk of The Denial Machine:

a/k/a Oiznop

I find it very interesting that many of the cooler than normal tempearature anomolies are found in many an equatorial/tropical region. Also, if our cool weather loving/panic mongering/Al Gore worshiping/non-political/free thinking friends feel that the earth is warming by leaps and bounds to the point of disaster where we have to tax our wealth and change our lifestyles through government control, why is the WHOLE planet not red???? After all, it is GLO-BULL Warming, not Colorado Warming or Pittsburgh Warming, or Argentina Warming, isn't it????

Still Waiting for Summer to Start. GLO-BULL WARMING IS A CROCK!!!!!!!

Bill:

That warm area in Central SA certainly seems to correspond nicely with the recent volcanic eruption there, doesn't it? Reply: The Eruption was farther south than that.

I really find the 'warmest/coolest... since' followed by a time period within a year or a few years to be a journalistic exercise in catastrophism that doesn't provide much useful information. I think it started during the Iraq Occupation when the press started quoting things like "the most people killed since...".

Elmer:

When you say "Continental US", are you including Alaska in the North American continent?

I don not think they are including AK and HI

GSN:

Oiznop, you should leave the science to the scientists. I am not even really sure to begin telling you all the ways your own personal "analysis" if wrong. Typing in all capitals does not necessarily make something true.

Paulo:

This year is predicted to be cold, since we are in a La Nina stage, and some cyclic alterations in both North Atlantic and Pacific circulation also imply a colder than average weather.
Add that solar activity is low and there was a significant volcanic eruption in Chile in spring.
I think the winter will be cold and the summer 2009 again unusually cold and I believe some storms during next year will made historic headlines again.

Then, as 2010 sets up, during the year I think the oil crisis will climax, the warming trend may return, peaking around the peak of sunspot cycle 24 around 2012. Despite the fact that the sun affects climate, our pollution only contributes to create a unbalancing in the stability of weather patterns. Its all related: climate change, capitalism creating lack of resources and oil crisis, social unrest, famine, energy crisis.
In soon, most of mankind will not have doubts about it. Unfortunately it will be late and we will crash in a world depression, but hopefully we will surely change to the better.

Gary B:

Oiznop - while your observation is brilliant, you failed to point out all of the pretty red colors near the poles and over Siberia. By the way, I live in Pennsylvania, near Lake Erie, and our summer has been beautiful. I have relatives who live in Virgina, same story, beautiful normal summer. Global cooling - must be a Pittsburgh thing.

Also, if our cool weather loving/panic mongering/Al Gore worshiping/non-political/free thinking friends....

Brett, is it neccessary for people to use degrading comments to descibe other people who have different viewpoints? It is ok to express one's opinion, but to constantly denigrate others while doing so, is childish and goes against what this blog was set up to achieve. IMHO.

What I meant, is that many people, me included, come here for intelligent, meaningful, polite discussion about weather and climate. I don't come here to be called names or to be belittled.

I don't advocate censoring anyone. A little editorial encouragement, to lose the name calling, would be great. Otherwise, the format of this blog will be cheapened and I'm afraid many will discontinue visiting it.

(Gary: Give me an example from what was posted here of what you consider name-calling. That will allow me to explain better. I try to delete that stuff if it is directed at someone in particular.)

Just for Oiznop - no I don't like Al Gore, carbon taxes, or ice ages. Just tired of your rhetoric.

Rick:

Hello Brett - a question for Brett or others ... the high mid latitude areas in both the north & south hemispheres seem to be predominately anomalies of either above or below normal temperatues. Also they seem to have a pattern of regularly alternating ... in the south you could fit a wave to the pattern with cools in the troughs & warms in the peaks. I know this map projection is a poor one but I don't think it accounts for the pattern except to alter the shape of the wave. Is it just the jet stream? If so is the treatment of the data not accounting for stationary ridges & is that what caused the east Russia warmth in July. Lots of stuff here for the curious.
Have a great weekend folks.
Also, I may be imagining it but the posters seem to be better behaved of late with less name calling etc by both sides. A welcome improvement.

Emiliano:

Oiznop is going to love this: Low temperature for tonight in Pittsburgh, 54 F.
Mark, I guess we will hear this is proof Global Warming is a crock!

Travis:

Temperature data from UAH is also out:

http://vortex.nsstc.uah.edu/data/msu/t2lt/uahncdc.lt

Land temperature anomalies at or above normal while the oceans are still a bit below, specifically in the tropics.

In the US and globally, July was cooler than the past couple years, but warmer than in 2004.

Dave:

This is really good information. The AWG theory put under the scrutiny of unbiased data. It doesnt seem to be holding up to well at the moment, but who knows, it might yet win out.

No surprises to see a very large blue spot over the UK. It being July, our one time of the year when we hope to have a bit of warmth, a bit of sun peering through the gloom, but alas no, not this year.

Infact I would guess that there is always a blue anomaly above the UK. The diagram just confirms how cold this summer has been here.

Adamant:

Brett, To follow on Gary B's comment- the reason that I don't post anymore (or in fact follow the blog as much) is that I was accused of wearing a tin foil hat because I made some points about dealing more proactively with global warming/climate change. It's obvious that there are different points of view being expressed here, often based on personal and professional bias, which is fine. What is not fine is to CONTINUE TO SHOUT over and over the same sad lines and put down those who don't agree with your perspective.

tombs:

please explain why its feels like late september in early august.Why is that new england has these low presuure systems thats stalls constantly yr after yr after yr .why is it that April has a heatwave for one week than it rain and some sun for the better part april and most of May.Why does winter start in late October and ends in april then it 2 months of cold damp with no spring Brett,maybe you should live in any parts New england then you will wake up.

Reply: I was born and lived in New England (RI) for twenty years. I am awake.

Dennis Hlinka:

Paulo: "This year is predicted to be cold, since we are in a La Nina stage, and some cyclic alterations in both North Atlantic and Pacific circulation also imply a colder than average weather. Add that solar activity is low and there was a significant volcanic eruption in Chile in spring."

The latest satellite temperatures appear to confirm that they have reached a minimum early this year:
http://wattsupwiththat.files.wordpress.com/2008/08/uah_july_08-520.png
http://wattsupwiththat.files.wordpress.com/2008/08/rss-july-2008-520.png?w=510&h=272

Global satellite temperatures over the past 30 years have basically leveled out for the past 8 years after rising from their minimums back in the 1980's. This despite the cherry picked data from ICECAP using 1998 as their starting point in their continuing efforts to "prove" that temperatures are in a dramatic cooling trend. The minimum we reached this year is still above all the other significant minimums reported over the 30-year satellite temperature record. The temperatures now appear to be oscillating back up to the 0.1-0.2C average temperautre range observed for the past 8 years.

As Paulo later says: "Then, as 2010 sets up...the warming trend may return, peaking around the peak of sunspot cycle 24 around 2012."


This July information for the U.S. is from NOAA:

July temperatures were generally higher than average across the West and Northeast and below average in the Midwest.

Five states (Conn., Mass., N.J., R.I. and Utah) were much warmer than average. Rhode Island had its sixth warmest July, and Massachusetts and Utah both had their eighth warmest July, based on statewide data going back to 1895. Six states (Ill., Ind., Ky., Mo., N.M. and W.Va.) were cooler than average.

Based on NOAA’s Residential Energy Demand Temperature Index, contiguous U.S. temperature-related energy demand was approximately three percent above average in July.


Finally, I copied the following information from the "Watts Up With That?" site:

http://sciencedude.freedomblogging.com/files/2008/08/tempchart.jpg

"The increase in temperatures in Santa Ana, as well as an increase in extreme heat days and in heat waves is primarily — about 60 percent — due to the ‘urban heat island effect,’ ” says Bill Patzert, a climatologist at the Jet Propulsion Laboratory in Pasadena."

"Santa Ana is embedded in the dramatic urbanization or ‘extreme makeover’ of Orange County. More homes, lawns, shopping centers, traffic, freeways and agriculture, all absorbing and retaining solar radiation, making Santa Ana and Orange County warmer."

"On a larger scale, Orange County is atmospherically connected to our ever-expanding and warming Southern California megalopolis. Global warming due to increasing greenhouse gases is responsible for about 40 percent of the overall heating observed in Southern California."

Both the UHI (60%) and GHG's (40%) contributions to the observed heating are anthropogenically produced and not through natural occurrences.

"Global cooling - must be a Pittsburgh thing."
I live in West Virginia but I am from the Susquehanna Valley area in PA. Bothe here and there have had unusually cool summers, there have been some hot spells but nothing that has compared to years past. Woke up this morning and it felt like late September. The whole day is below average.

From The Desk Of The Denial Machine:

OOOOH..Everybody's picking on old Oiz, I see! Good, cauz I am hungry.

Oiznop, you should leave the science to the scientists. I am not even really sure to begin telling you all the ways your own personal "analysis" if wrong. Typing in all capitals does not necessarily make something true.

REPLY: Just making an observation there, GSN. An observation that YOU don't like (oops sorry, used caps, I apologize LOL!). Why can't you look at the chart that's been provided and admit the truth? Is it because you can't handle the truth?

GARY B: If you don't like my rhetoric, then why do you read it?

Oiznop - while your observation is brilliant, you failed to point out all of the pretty red colors near the poles and over Siberia.

REPLY: Yeah, all the pretty red colors. Looks like the blue outnumbers the red, woudn't you say. What, are the poles 15 degrees instead of 5 degrees? GASP!!!! SOUND THE ALARM!!!! BETTER PASS THAT TAX SO THE ICE DOESN'T MELT!!!!

By the way, I live in Pennsylvania, near Lake Erie, and our summer has been beautiful. I have relatives who live in Virgina, same story, beautiful normal summer. Global cooling - must be a Pittsburgh thing.

REPLY: Ah, yes Dreary Erie! Where the snow never stops. I am sorry, Gary, but 54 degree nights in July (last year) and August (this year) do not constitute for a normal summer. But then again, I have made it perfectly clear that I have a different interpretation than most of these cool weather lovers as to what a real summer is. 2005. THAT was a real summer.

Also, if our cool weather loving/panic mongering/Al Gore worshiping/non-political/free thinking friends....

Brett, is it neccessary for people to use degrading comments to descibe other people who have different viewpoints?

REPLY: How is this degrading? Looks like someone else can't handle the truth as well. All I get on here is that the "Vast Right Wing Conspiracy" and the "Denial Machine" that. (I am not saying it's from you personally). Seems the "colorful" "Degrading" terms happen on the other side too. You see, Gary, the difference is guys like you take these truthful descriptions as being "degrading", where as I like to play with them, hence forth my new user name. You guys really need to lighten up.

It is ok to express one's opinion, but to constantly denigrate others while doing so, is childish and goes against what this blog was set up to achieve. IMHO.

REPLY: Show me the denigration. Again, you can't handle the truth. You don't like a certain adjective that someone uses that is not threatening or vulgar and you interpert it as being denigrating. Why is that?

Low temperature for tonight in Pittsburgh, 54 F.
Mark, I guess we will hear this is proof Global Warming is a crock!

REPLY: Your prowess of observation is astonishing there, E. Tell me, has winter hit in the patagonias yet? Or are you "still sweltering and waiting for winter?" I will have to check the international page and see.

DENY DENY DENY THE GLO-BULL WARMING LIE!!!!!

Thor:

I like carbon taxes. It takes the pollution out of all that unnecessary lawn work using those infernal gas-powered machines. However maybe there should be an allocation first so that people could use their vehicles. Of course, this would mean more bureaucracy.

cs:

Man! With all this data it's no wonder scientist have a hard time figuring out the Global Warming issues.

Kipp Alpert:

Oiznop: As you know global warming isn't Connecticut warming or Penn. warming. Ask the Filipinos if they believe in global warming. Americans are lucky because of our wealth and our latitude. In the future we will experience strange weather, and this weather will only get worse. I grew great tomatoes this year liked they never did before. You'll get your warming, but be careful what you wish for. Please don't forget you space heater this week.
later,KIPP

Kipp Alpert:

Dennis Hlinka:
I have read that ENSO will change with more El Nino events of more strength, and less la Nina's with less cooling. I don't buy the frequency scenario because they are climate cycles but was is your take on these oscillations change because of warming.
Thanks: KIPP

Kipp Alpert:

cs:
I have a good Idea: Take a bottle of club soda and put into the Sun for about fifteen minutes. Then you will see what CO2 does in our atmosphere with warm air and water vapor. This is the basis of Global warming. When I started on this blog. I knew what you do. Since then by joining this blog, I have learned much more, which is still a drop in the bucket. Good Luck, KIPP

JP:

Dennis,
Since you endorsed the data from that OC article, could you please detail how they came up with thier data )60% UHI, 40% GHG)? The author never did.

Kipp Alpert:

Gary B.{BRETT:} has hit the nail on the head. I don't want to discuss politics, but I need to defend those that I respect. I would easily give up talking about politics, although you think that they are inexorably linked. Well they are for some people, but I would use the logic Argumentum populom, what many people think, doesn't make it right. If this is just a political sounding board for disgruntled people then that is how this board is cheapened. There will always be fringe thinkers, a gang of people don't need to rant or insult the messengers. Even the price of gas? I knew no science when I came aboard, and have learned much. But when someone comes here they are immediately insulted by a large gang of people who are venting there frustrations about how Global Warming is being played out in the media and fears that we are now the new socialist state. Why should I read this when I want to understand SSTs or what effects the ENSO have today. You are the moderator, and I think if you kept out some of the Political cheap shots, this board would grow and debate both sides would flourish. I can get very political myself, but I am reacting to the gang, not starting the trash talk. I defend those who I believe in, because I honestly think this board is tilted, in a negative way. I rather learn more of what you know, and would stay here for that. Just To much opinion, not enough scientific discourse. Gary B. is right. If people are threatened by Global Warming what ever happened to alternate solutions or fighting the science instead of ranting and complaining, or attacking those that do! Even in the freeist country there are rules to go by! Why don't we try for a little more.
Thanks, KIPP

Patrick Henry:

Land temperature anomalies at or above normal while the oceans are still a bit below

Travis,

UAH was statistically right at normal for the globe at 0.06 anomaly. This is lower than March during the La Nina.

Every month this year - La Nina or no - has been right around normal. Hansen and the IPCC are falling flat on their faces. Over here in the UK, the Met Office has blown their second straight summer forecast. NSIDC blew their summer ice forecast and had to make a press release a few weeks ago saying that they didn't actually know how thick the ice was.

It is time for the alarmists to find a new religion that doesn't rely on superstition, disinformation and political intimidation.
