Scientists developed a very high resolution dataset that goes back 6 decades: TerraClimate (Nature link). I will/may be examining their data (with model stuffing) in the next few posts.

The first thing I downloaded was the srad dataset, all 8.4GB of it, from 1958 to 2021.

I was a little disappointed that it only covers land. No oceans. But let’s see what we can get out of it anyway …

These numbers suggest this is solar downwelling, not Net Solar (minus solar upwelling). Also dissapointed, but will do.

If this data with model filling is true, the ~3 W/m2 difference (~179 minus ~176) over 6 decades is WAY more than could even be hypothesized by carbon dioxide warming over the last 2 centuries.

Again we see that the solar shortwave is the dominant force in all the global warming we observed.

Sorry, times up.

Best regards, -Z

P.S. No, I have no idea what happened there in the early 1970s.

1. LMAO, this type of rhetoric is what I’m talking about. Look what they are saying by innuendo:

CO2 really did cause an increase in surface longwave … and this caused all sorts of changes that allowed an equal amount of shortwave to reach the surface … thereby explaining the longwave, but no greater.

1. lol. So after CO2 did its work, it turns out the sun did it. And this is satisfying to you?

The canonical description of the GH effect found in all introductory textbooks explains how GHGs can warm WITHOUT changes on the shortwave side. The shortwave remains the same and surface longwave changes.

But if the longwave changes EXACTLY as shortwave, then I’m sorry, you don’t need the GH effect for that.

In fact, if GHGs forced surface longwave up, and this had subsequent effects of clearing the skies and/or making surface more absorptive and this allowed more shortwave to reach surface, this would be ADDITIONAL energy – thus we would see longwave changes beyond that explained by shortwave. But we don’t.

9. Literally demonstrates exactly what I said, and shows their pathetic narrative to mix up cause and effect.

ASR is the dominant force, and no, GHGs did not cause extra ASR. GHGs soaked up the extra longwave that came after ASR.

All this however demonstrates that there is now 3 BS GH effect narratives that contradict themselves:

1) a) CO2 reduces OLR. b) That did not happen. OK fair enough because …
2) Surface longwave flux increases and brings OLR back to previous value, so statement #1a never really takes place. OK
3) However this was all supposed to happen without extra shortwave. But More shortwave ended up at the surface and perfectly explains longwave, so statement #1 must have caused it, but now statement #2 doesn’t make sense as the shortwave perfectly explains surface longwave.

I bet you still don’t see the problem with this. You think they are doing legitimate science rather than making excuses for their failed theory. With rhetoric of mixing up cause and effect anything is possible.

“Shortwave and longwave contributions to global warming under increased CO2”

No, that is not whay they show. They attempt to show where longwave goes after ASR. ASR is the bank account that gets divided. There is no longwave contribution, unless you believe in their “pull” mechanism. There is no pull mechanism. There is a push mechanism from ASR.

Wrong. Feedbacks that increase absorption of shortwave always have been a core part of greenhouse gas effect warming of Earth.

2. Tom Dayton says:

“Don’t you see what this is? This is lifting yourself by your bootstraps.”

No, it’s called feedback, which always has been part of our understanding of greenhouse gas warming of Earth. The most well known example of that in introductory explanations is reduction of albedo by melting of ice and snow.

“Increase in net solar will melt more ive and snow. CO2 will not cause more net solar.”

CO2 causes warming that melts ice and snow. Those are examples of decreasing albedo—decreasing reflection of solar. Decreased reflection is increased absorption of solar.

3. Not at the poles, where there is a reverse greenhouse effect (CO2 enhances OLR). Only in places near warmer water.

Stop using <6% of Earth's surface area as an explanation for the rest. This is not where there majority of absorptive action is taking place.

The sun too can "melt" and make object more absorptive. And then you can claim CO2 did it.

Like

1. You are obviously braindead, and can’t see the trickery.

They don’t prove that net solar is a feedback, they merely suggest it with assertion because they are desperate.

In their model, which has NOTHING to do with the SURFACE, CO2 reduces OLR by 4 W/m^2 and then takes 140 years to recover (Fig 1A). Then in Fig 1B, they show solar forcing raising OLR by 4 W/m^2 over 140 years.

NOWHERE in the paper do they prove how A caused B. NOWHERE!

Things happening simultaneously does not prove A caused B.

Furthermore, CERES observations show that OLR has pretty much stayed flat within a 0.15 W/m^2 range for the last 20 years. Their model is a unicorn.

Despite the fact that word “surface” appears 59 times in the paper, their model is TOA, not the surface.

This paper is pure witchcraft. They show no causation. They don’t show a diagram or model at the surface. They don’t because it would have to show both CO2 LW forcing AND net solar forcing, but the total forcing (see my CERES article) is almost exactly equal to just the net solar forcing.

It’s amusing that you don’t see their trickery.

If we were suddenly bombarded by an asteroid storm, they too can model that concurrent with CO2 rise and by innuendo blame it on CO2 and humans.

1. Tom Dayton says:

CO2 long has been increasing due to human activities. That was not caused by solar. Humans increased reflective aerosols, then around 1970 started reducing that increase. Neither of those events was caused by solar. Meanwhile, solar reaching TOA has been decreasing since 1960.

2. We’re not talking about solar at TOA, but solar at the surface. Net solar at the surface is only slightly greater than in 1960. So explain this with CO2. If CO2 clears the skies and allows more sunshine in, why was there a trough between 1960 and 2000?

Logic would tell you there is a natural cycle.

The human contribution is pitiful, which is why you can’t/won’t enumerate it. But if you want to blame humans, you will talk about completely from that perspective. The lack of enumeration will make it seems humans did it all, whereas in reality, it’s a pitiful negligible amount too hard to even enumerate.

5. While there maybe independence from CO2, there is no independence from INDUSTRY. Industry has increased. Pollution has increased (China, India, Brazil, etc) – and the effects are rarely simply at the place of industry or downwind from them.

Fool, there was a peak in net solar ~1960. You constantly avoid this. There was an increase from ~1920 to 1960, then a decrease from ~1960 to ~1995, then another increase. And your cult wants to only attribute the current rise to industry. Industry has grown during that whole time period. You have no explanation for the rise and fall in the past.

Fool, your article was trying to link LW changes from CO2 to solar increase. CO2 in their model reduces OLR, and 140 years later brings the change back to ZERO. What they want to do is explain OLR being POSITIVE (which it isn’t), but CO2 alone never makes it positive, even in their model. So what was the effing point in bringing in CO2? huh? ANSWER THAT!

The point was to associate CO2 with an increase in ASR!

If they just wanted to show how aerosol, black carbon, etc changes ASR, there was no effing need to bring CO2 into the discussion. But they did, and that’s what I’m commenting on … the innuendo that CO2 caused these ASR changes as a feedback.

There is not a lot of ice and snow in Europe – ”The surface records suggest a continuation of the surface solar brightening beyond 2000 at numerous stations in Europe and the United States, as well as parts of east Asia (Korea). Surface solar radiation variations in Europe after 2000 are dominated by a large positive anomaly in the year 2003 with its unprecedented summer heat wave, exceeding 10 Wm−2 on an annual and 20 Wm−2 on a summer mean basis in central Europe. The brightening seen at sites in Antarctica during the 1990s, influenced by a recovery from the low atmospheric transparency after the Mount Pinatubo volcanic eruption in 1991, fades after 2000.”

Our solar system moves in and out of spiral arms of our galaxy as we spin around the center of the galaxy. This means that we encounter varying degrees og cosmic radiation on our cosmic journey. Meaning that cosmic radiation received on earth does not only vary with the magnetic field of the earth and our sun, but in addition has a cosmic factor. Cosmic radiation has a direct effect on the cloudyness of our planet. At least there is some evidence to support that. Reference is made to the research made by Henrik Svensmark. Now this is some real science – science that investigates cause and effect, as opposed to the pseudoscience og AGW which fakes temperature data in order to keep alive a fake theory which has only resulted in models that predict wrongly. If the theory could be backed up by observations, there would be no reason to tamper with the temperature data sets, now would there…
