Offset by converting solar radiation into electricity. The net effect is cooling.
Offset?
The heat island effect showed it absolutely wasn't offset.
If it was neutral, it would be cooler at the array and warmer where the electricity was used.

Offset by converting solar radiation into electricity. The net effect is cooling.
None of that disputes anything I just wrote, dummy.I just expalined why you Trolling POS
Here's a more official version
Mid-Holocene Warm Period – About 6,000 Years Ago Paleoclimatologists have long suspected that the "middle Holocene," a period roughly from 7,000 to 5,000 years ago, was warmer than the present day. Terms like the Altithermal or Hypsithermal or Climatic Optimum have all been used to refer to this warm period that marked the middle of the current interglacial period. Today, however, we know that these terms are obsolete and that the truth of the Holocene is more complicated than originally believed. What is most remarkable about the mid-Holocene is that we now have a good understanding of both the global patterns of temperature change during that period and what caused them. It appears clear that changes in Earth's orbit have operated slowly over thousands and millions of years to change the amount of solar radiation reaching each latitudinal band of Earth during each month. These orbital changes can be easily calculated and predict that the Northern Hemisphere should have been warmer than today during the mid-Holocene in the summer and colder in the winter. The combination of warmer summers and colder winters is apparent for some regions in the proxy records and model simulations. There are some important exceptions to this pattern, however, including colder summers in the monsoon regions of Africa and Asia due to stronger monsoons with associated increased cloud cover during the mid-Holocene, and warmer winters at high latitudes due to reduction of winter sea ice cover caused by more summer melting. In summary, the mid-Holocene, roughly 6,000 years ago, was generally warmer than today during summer in the Northern Hemisphere. In some locations, this could be true for winter as well. Moreover, we clearly know the cause of this natural warming, and we know without doubt that this proven "astronomical" climate forcing mechanism cannot be responsible for the warming over the last 100 years.
Entirely different thing. That's the concrete jungle. Not your silly belief that electricity usage is warming the planet. Electricity usage is the same in both cases; electricity generated from non-solar sources and electricity generated from solar sources. So whatever heat you think is being returned to the planet from using electricity is in both cases. But only one case reduces the solar radiation that strikes the surface of the planet. So incrementally the widespread use of solar power will have a cooling effect on the planet because the decreased albedo of the panel itself is more than offset by the solar radiation converted to radiation.Offset?
The heat island effect showed it absolutely wasn't offset.
If it was neutral, it would be cooler at the array and warmer where the electricity was used.
I just explained why you repeat Trolling POSding said:
And yet our planet is 2C cooler than in the past with 120 ppm more atmospheric CO2.
Still not seeing anything that disputes what I said....I just explained why you repeat Trolling POS

Primarily the sun, urban heat island effect and the reduced albedo of an interglacial cycle.
Solar variability and orbital forcings coupled with albedo of the northern hemisphere have driven all climate fluctuations and environmental uncertainty over the last 3 million years because the planet is uniquely configured for bipolar glaciation and the planet's temperature is at the threshhold for extensive northern hemisphere glaciation.
One would think the planet being on the precipice of extensive northern hemisphere glaciation would be the starting point of every climate discussion. We can see signs of it every winter.
Excerpt from Bond: “Over the last 12,000 years virtually every centennial time scale increase in drift ice documented in our North Atlantic records was tied to a distinct interval of variable and, overall, reduced solar output.”
Finding from Neff: Correlation coefficients of .55 and .60.
Excerpt from Usoskin: “The long term trends in solar data and in northern hemisphere temperatures have a correlation coefficient of about 0.7 — .8 at a 94% — 98% confidence level.”
Excerpt from Shaviv: “We find that at least 66% of the variance in the paleotemperature trend could be attributed to CRF [Cosmic Ray Flux] variations likely due to solar system passages through the spiral arms of the galaxy.” [Not strictly due to solar activity, but implicating the GCR, or CRF, that solar activity modulates.]

And that’s just old stuff. Here are four random recent papers.Excerpt from Mangini: “… a high correlation between δ18O in SPA 12 and D14C (r =0.61). The maxima of δ18O coincide with solar minima (Dalton, Maunder, Sporer, Wolf, as well as with minima at around AD 700, 500 and 300). This correlation indicates that the variability of δ18O is driven by solar changes, in agreement with previous results on Holocene stalagmites from Oman, and from Central Germany.”
Excerpt from Ogurtsov: “Statistical analysis of the carbon and oxygen stable isotope records reveals variations in the periods around 100, 11 and 3 years. A century scale connection between the 13C/12C record and solar activity is most evident.”
Excerpt from Di Rita: “The chronological correspondence between the ages of saltmarsh vegetation reductions and the minimum concentration values of 10Be in the GISP2 ice core supports the hypothesis that important fluctuations in the extent of the salt-marsh in the coastal Tavoliere plain are related to variations of solar activity.”
Excerpt from Raspopov: “Our analysis of 200-year climatic oscillations in modern times and also data of other researchers referred to above suggest that these climatic oscillations can be attributed to solar forcing. The results obtained in our study for climatic variations millions of years ago indicate, in our opinion, that the 200- year solar cycle exerted a strong influence on climate parameters at those time intervals as well.”
Excerpt from Tan: “Solar activity may be the dominant force that drove the same-phase variations of the temperature and precipitation in north central China.”
Excerpt from Solheim: “We find that for the Norwegian local stations investigated that 30-90% of the temperature increase in this period may be attributed to the Sun. For the average of 60 European stations we find ≈ 60% and globally (HadCRUT3) ≈ 50%. The same relations predict a temperature decrease of ≈ 0.9°C globally and 1.1−1.7°C for the Norwegian stations investigated from solar cycle 23 to 24.”
Entirely different thing.
I'm sorry, but you don't know what you're talking aboutIMHO, the question should be how much do we know about climate change and how much change is due to anthropogenic causes. Currently, we do not know how, much warming is due to humanity and we also do not know how much effect any of the solutions pushed by the GWers would have. IOW, would we be wasting our money on projects and program that will have a miniscule effect AND what would the effect be on our society and that of the rest of the world. IMHO, anybody who says they know the answers to these questions is lying.
And how does this post (WTFUWT copy/paste) contradict mine in any way?Here you go from Watts Up With That? 2012 post,

Plenty of anti-CO2 alarmists know about this stuff. Mike Lockwood and Claus Fröhlich, for instance, in their 2007 paper: “Recent oppositely directed trends in solar climate forcings and the global mean surface air temperature” (Proc. R. Soc. A), began by documenting how “[a] number of studies have indicated that solar variations had an effect on preindustrial climate throughout the Holocene.” In support, they cited 17 papers, the Bond and Neff articles from above, plus:
The correlations in most of these papers are not directly to temperature. They are to temperature proxies, some of which have a complex relationship with temperature, like Neff 2001, which found a correlation between solar activity and rainfall. Even so, the correlations tend to be strong, as if the whole gyre is somehow moving in broad synchrony with solar activity.
Some studies do examine correlations between solar activity proxies and direct temperature proxies, like the ratio of Oxygen18 to Oxygen16 in geologic samples. One such study (highlighted in Kirkby 2007) is Mangini et. al. 2005, “Reconstruction of temperature in the Central Alps during the past 2000 yr from a δ18O stalagmite record.”

Actually that wasn't my claim, dummy. Try reading it again and see if you can state it properly.Nope.
Your claim is that the energy converted into electricity isn't available to heat the Earth.
But the area around the solar array is hotter, not cooler. When you add that to the heat given off when the electricity is used, it's net warming, not net cooling.
Not your silly belief that electricity usage is warming the planet.
I never claimed that. Not even once.
But only one case reduces the solar radiation that strikes the surface of the planet.
You mean the case where the albedo of the solar panel is lower than the albedo of the planet?
Tell me again how that cools anything.
the decreased albedo of the panel itself
Glad you finally figured that one out.
is more than offset by the solar radiation converted to radiation.
Tell me the efficiency of your theoretical "cooling panel" and I'll be glad to show you your error.
Actually that wasn't my claim, dummy. Try reading it again and see if you can state it properly.
Now you are getting it. Good boy.Any solar radiation that is converted into electricity is solar radiation which does not heat the surface of the earth.
Now you are getting it. Good boy.
Just don't screw up the next part and everything will be fine.
The modeling from the paper I linked showed a regional cooling of 2C.I've gotten your error since you first posted it.
If all those panels are cooling the vicinity, why is the vicinity warmer?
The modeling from the paper I linked showed a regional cooling of 2C.
And like I said before there's been contradicting studies and I choose to believe the one that results in something which makes sense.Actual measurements show actual heating.
As with the Urban Heat Island (UHI) effect, large PV power plants induce a landscape change that reduces albedo so that the modified landscape is darker and, therefore, less reflective. Lowering the terrestrial albedo from ~20% in natural deserts12 to ~5% over PV panels13 alters the energy balance of absorption, storage, and release of short- and longwave radiation14,15.
The Photovoltaic Heat Island Effect: Larger solar power plants increase local temperatures - Scientific Reports
While photovoltaic (PV) renewable energy production has surged, concerns remain about whether or not PV power plants induce a “heat island” (PVHI) effect, much like the increase in ambient temperatures relative to wildlands generates an Urban Heat Island effect in cities.

Check out the lower albedo.
Right. Your study was theoretical, the one I posted took actual measurements.And like I said before there's been contradicting studies and I choose to believe the one that results in something which makes sense.
