Every month University of Alabama in Huntsville climatologists John Christy and Roy Spencer publish the latest global temperature trend data obtained from NOAA satellites. For the month of July 2015 they report:

July temperatures (preliminary)

Global composite temp.: +0.18 C (about 0.32 degrees Fahrenheit) above 30-year average for July.

Northern Hemisphere: +0.33 C (about 0.60 degrees Fahrenheit) above 30-year average for July.

Southern Hemisphere: +0.03 C (about 0.05 degrees Fahrenheit) above 30-year average for July.

Tropics: +0.48 C (about 0.86 degrees Fahrenheit) above 30-year average for July.

UAH

UAH

Notes on data released Aug. 12, 2015:

The tropics continued to warm in July, although the areas between the tropics and both the Arctic and Antarctic regions cooled from June, said Dr. John Christy, director of the Earth System Science Center at The University of Alabama in Huntsville.

I've been living under a rock for the last 40 years. Did I miss something? Is the Earth's temperature slowly increasing or something?

[sarcasmic]

Yeah. That's what happens when you come out of an ice age.

[WTF]

Is the Earth's temperature slowly increasing or something?

Well, not really for the last 18 years or so.

[Notorious G.K.C.]

I think Ron Bailey wants to create a record showing that he followed the global warming trend, thus distancing himself from the more...skeptical...of the commenters.

[Jackand Ace]

He never distances himself all that far from the commenters.

Over at Wattsupwiththat, Robert Brown of Duke University has an article up that had me laughing out loud.

Problematic Adjustments And Divergences

As can be seen from the graphic above, there is a strong correlation between carbon dioxide increases and adjustments to the United States Historical Climatology Network (USHCN) temperature record. And these adjustments to the surface data in turn result in large divergences between surface data sets and satellite data sets.

It appears that the more CO2 enters the atmosphere, the more the surface temperature is adjusted to show warming over the industrial era.

Some pretty incredible claims, like that according to the GISS, the impact of the Urban Heat Island effect is to cool cities from the temperature they would experience under global warming. - the physical reality is that it warms cities.

[WTF]

So.....you're a climate denier, then?

[Almanian - Trump's Woodchipper]

I, too, deny climate.

[Pro Libertate]

I deny climate my essence.

[Pro Libertate]

There's science being used to show something useful. That's exactly the kind of finding that should be used to fix a measurement problem, not to get headlines and funding from,

[Jackand Ace]

"The tropics continued to warm in July, although the areas between the tropics and both the Arctic and Antarctic regions cooled from June, said Dr. John Christy"

Indeed, that's the ticket! 1998 doesn't work anymore, so start counting from June 2015.

[Set Us Up The Chipper]

You're a fucking idiot. He's talking about the characteristics of the latest data set.

[Jackand Ace]

Gotta highlight those downward trends, wherever they show up, and no matter how minuscule. Now, if only we can dismiss those pesky tropics...hey, it's always hot there anyway!

[tarran]

I think my favorite property of the ones possessed by superstitious science deniers like Joe here is that they project the very cargo-cult approach they have towards science to those who disagree with them.

It's unconscious incompetence at its purest. They completely misunderstand how science works, and assume that everyone else conforms to their misunderstanding.

[Pro Libertate]

What irks me is that if you even mildly criticize flaws in the science, you're a full-on DENIER. How anyone who respects science as a process for finding and exploring truth can do that is beyond me.

I've never been completely convinced that there isn't a warming trend that may have some human components, but it's so hard to tell whether any warming trend isn't mostly natural that all of the talk about catastrophic warming seems completely insane. Not to mention, just look at the known radical climate shifts during the time Homo sapiens has walked the planet, and you realize that dramatic change is part of climate history.

Personally, I'm far more concerned about the possibility of a return to glaciation. We're a little overdue for that--after all, we're still in an ice age, just biding our time during a geologically brief interglacial period.

That's because they don't respect science as a process for finding truth.

They have a superstition that man is hubristically destroying the Earth as a place people can live. They believe that the actions that people take that they (the believers) disagree with are the destructive hubris.

They want these superstitions to be true, so anybody saying "I are scientist, your superstition is scientifically proven" automatically must be right. And lacking any understanding of evidence or hypothesis testing etc, they can't handle a discussion in that arena. So they scream and have a tantrum instead and hope thereby to avoid the discussion they are unprepared for.

[Pro Libertate]

Confirmation bias for the win.

[mad.casual]

You're a fucking idiot. He's talking about the characteristics of the latest data set.

You're not talking to a human being, it's a climate killbot. Certain words like 'cool' or 'decrease' automatically trigger...

Someone said trigger! *Opens fire*

Go here to see the monthly mean satellite temperatures for the lower troposphere since 1978.

But satellites don't orbit in the lower troposphere. Or do they? [ducks suspiciously]

[Als? als? wik]

At least UAH has the decency to only go back to the 70's, when humans first had access to weather satellites.

You know how we used to measure "the temperature" of the oceans? Some random ships would chuck a bucket overboard, haul it up and stick a mercury thermometer in there, and some random dude would eyeball it.

Yet we're supposed to panic because top men are warning us over trends measured in tenths of a degree. To paraphrase Dennis Miller, we were still crapping in outhouses in the early 20th century but we had a lock on the exact mean surface temps of the entire globe?

[R C Dean]

Oh, sure, you richies with your fancy outhouses . . . .

Back in the day, we had to crap uphill in the snow!

[Fist of Etiquette]

That's what those super accurate if not exactly verifiable computer models were for.

[Lord at War]

Yup... I still hear the stories from my mom- they still had an outhouse in the mid-40's- and you followed the clothesline to find it at night!

[Old Man With Candy]

WE'RE ALL GOING TO DIIIIIIIIIIIEEEEEEE!

[Jackand Ace]

Surface temperatures(where we reside) reveal that July was the warmest July on record.

2015 is headed toward the hottest year since record keeping began. Pause? Not so much.
