We are all doomed, hold your breath and cancel sporting events…..too much breathing. CO2 is taking over the planet, what’s that noise? oh no, it’s here aggggggggggggggggggggh

Incredibly cold summer here in southern Ontario Canada, highs around 21 degree C on a good day.

“Significantly” down?
—————————-
Down on last month … If the same thing happened for July it would be below the 30 year average. But would that be significant. If you look at the plot you can see that not much is going on temperature-wise through out the duration of the records. ~+0.2 degC does not set alarm bells ringing around here, what about there ?

Down significantly again! Here are the headlines that have appeared at WUWT on UAH monthly temperature reports in the past 12 months. ….

and if you look at the same plot on a warmist site, it would be an extreme catastrophe, a dangerous calamity or some other adjective with an overused preceding modifer meaning the exact opposite of the reality of the data.

I have updated my graph:

Take it the way humans do. At each end. }
LOL… Wish I’d have had you in school.

Mid North Carolina was cold too. (It was 64F this morning) and we have had only a eight days of 90-92 F and one day at 95F so far this year. Nothing above 90F in the forecast either.
Ten years ago we had 17 days 90F and above in May, with five days at 95F and over (2 at 98F)
July 2004 had 24 days over 90F with seven days at 98F or above.
My white clover is still doing well and blooming instead of dying back as it usually does in summer.

“Anyone spot any bias (intentional or otherwise) in these descriptions?”
We like it when it gets cooler because it falsifies CO2AGW more. You caught us there.

Nice work, Nigel.

“Anyone spot any bias (intentional or otherwise) in these descriptions?”
When it drops , this is significant.
When it stays the same, as it has basically done for 16 or so years, this is also significant
Why ? Because all the so-called climate scientists tell us that CO2 drives temperatures.
And they are manifestly WRONG.

Same here south of Lake Erie, other than a week and a half or so in early July that was hot, we’ve had 70-80F highs this summer.
Here In Red Deer Alberta it’s a whopping 17C

From Bob Tisdale on August 5, 2013 at 2:03 pm:

There’s an unusual warming event in the North Pacific in July that I’ll be reporting on hopefully tomorrow.

Godzilla?
Perhaps that movie annoyed him, and he was thinking about showing up for the mid-July release. But after the decades of propagandist filmography convincing us such results of nuclear testing were ludicrously non-existent, with successful franchises such as Power Rangers making the concept of giant monsters even more laughable, he likely decided to “stay home”, blow off some steam, and remain unreal.

How about this paper?

Abstract
24 year of Meteosat hourly thermal infrared data have been used to study planetary surface temperature change. Thermal infrared radiation in the 10.5-12.5mm spectral window is not affected by CO2 and only slightly by atmospheric water vapor. Satellite thermal infrared data have been converted to brightness temperatures as prescribed by Eumetsat. Hourly brightness temperature images were then composed to corresponding noon and midnight temperature data fields. The resulting data fields were cloud filtered using 10, 20 and 30 day maximum temperature substitution. Filtered data were subsequently averaged for two 10 yearly periods: 1986-1995 and 1996-2005. Finally the change in brightness temperature was determined by subtraction. In addition nine locations were selected and data series were extracted and studied for the period 1982-2006. Our observations point to a decrease in planetary temperature over almost the entire hemisphere, most likely due to an increase of cloudiness. Two small areas are found where a considerable temperature increase has occurred. They are explained in terms of major human interventions in the hydrological balance at the earth surface.”

Hi AndyG55
I have been watching the same thing for 2 or 3 years now. I take the 1997/2001 El Nino/La Nina cycle out by taking the periods Dec 1978 to March 1997 (the latter date when the ENSO index was -0.1, the start of the 1997 El Nino) and the period June 2001 (ENSO index -0.1, the end of the La Nina) to the present. The trend for those two periods are at present identical at 0.36 degrees C per century.
Looking at it this way, the trend determinded by drawing a line through the entire graph (1.44 Degrees per century) is really determined mostly by the step increase from 1997 to 2001.
The first period is 18 yrs 4 months. The second period so far is 12 years. Be interesting to see what the results are 6 years from now. If the trends are close I will really have my doubts about how much influence C)2 has on temperature. Using UAH v5.6.
RSS results for the same period are 0.72 and -0.72 up to May 2013.

None of these numbers gives any idea what the energy balance looks like – are we accumulating or shedding energy from the sun?

Atmospheric temperature provides very little information on atmospheric energy content as the atmospheric enthalpy is not recorded. Apparently, the atmospheric humidity is falling; it is entirely possible that the positive atmospheric temperature anomalies are entirely due to the reduction in atmospheric enthalpy.
During the recent media induced frenzy about Death Valley temperatures, the temperature in Death Valley was around 125F; the temperature in Central Florida was around 85F. The energy content of the air in Central Florida in Kilojoules per Kilogram, was nearly twice that of the energy content of the air in Death Valley. This is because the humidity in Central Florida was 90% or so and in Death Valley it was close to zero.
It is probable that the entire global warming hooplah is due to use of averages of incorrect metrics.

I can’t even think of a good way to take Earth’s temperature.
I can. Take the temperature T measured in each cell of a surface-spanning spherical icosahedral tessellation (that can be rescaled at will to a finer-grained coverage without any Jacobean-linked cell distortion like the one that occurs in spherical polar coordinates or latitude/longitude). Evaluate T^4 per cell. Sum it over the cells. Divide by the number of cells. Take the fourth root of the result. Do at least one subdivision of the tessellation (e.g. halve the cell size, get 4x as many cells) and repeat. Compare the two. Iterate the adaptive subdivision until the result converges, using the scaling of the variation of the subdivision and the eight order cumulant to estimate the error.
This root-root-mean-square average is the only measure of temperature that matters, as it is the “radiation temperature”, directly proportional to the Earth’s radiation rate ignoring its atmosphere. Pre-weighted by surface area, no less.
The current mean temperature is utterly irrelevant and indeed HIDES the radiation temperature.
The problem is that the Earth is actually capable of both warming and cooling that completely overwhelms the GHE while GHGs are neutral, increasing, or decreasing due to seemingly minor changes in the way heat is distributed. Atmospheric/oceanic circulation trends that increase mixing are warming. Ones that decrease mixing are cooling. That is, if tropical heat migrates to the poles, it is net warming. If tropical heat stays in the tropics, it is net cooling.
IMO the LIA was caused not by GHGs, not by solar variation per se, but by a transient variation in global circulation (which might or might not have been linked to solar variation, but I don’t have any good feel for how it might have been so linked). For a while the tropics heated up a little, increasing their radiative efficiency rapidly, but the heat was not conveyed north and south to the temperate and polar regions. The pole cooled more than the tropics heated up, because of the T^4.
Doing an adaptive iterative T^4 rrms average of the temperature (especially comparing the result to T average and T^2 rms average) is highly instructive in other ways as well. It reveals directly how inhomogeneous the temperature distribution is — is the current mean temperature arising — as some above suggested — because a small area is a lot warmer while the bulk of the area is a little cooler? You’ll never know looking at T alone, but you can tell at a glance by looking at the histogram of temperature anomalies, you can tell at a glance by comparing the various cumulants, evaluating the skew (did I mention that we might as well form the third order cumulant as well?) and kurtosis.
The bizarre thing is that the mean alone is almost completely mean-ingless, to a statistician. Without knowing the variance and other moments of the distribution, one doesn’t even know how reliable the measured mean is as a predictor of the true mean. In the case of radiatively cooled Earth, the mean TEMPERATURE is just great — if you want to know the enthalpy or something like that and can calculate it because you know heat capacities per cell (which we are clueless about, of course). Otherwise, it is rrms T^4 that matters in the Stefan-Boltzmann equation.

Professor Brown, thanks. I now better understand my boss’s glazed eyes after I explain to him why a piping or electrical system can’t be designed the way he wants it.

I’d rather it go back to “hot” — viewing the stars at nite is more comfortable.

I much prefer doing my star gazing on the cooler nights, well unless it sitting for hours watching meteors. But my camera likes it cold.

“sape” should be “space”
