New Science 25: Seven possible ways the sun could change our cloud cover

Earth and the solar wind. | Credit: NASA/GSFC

There’s a nuclear fusion reactor in the neighborhood that weighs 300,000 times more than Earth. It’s eight minutes away at the speed of light, has 99.8% of the mass of the solar system, and surrounds us with changing magnetic and electric fields while it rains down charged particles. Some years the Sun throws ten times as much extreme-UV our way as it does in other years. Virtually none of this is included in mainstream climate models.

The constant wind of charged particles blows at a million miles an hour — the flow waves and wiggles, shifting direction. The speed of the solar wind correlates with sea surface temperatures in the Atlantic. The solar magnetic field reaches right to the edge of the solar system, but despite that size, it turns itself completely upside down every 11 years. Reconnecting magnetic field lines cause explosions in space, and we have barely started to collect data on this. During the magnetic cycle the sun changes color, though the changes are invisible to us. The spectrum rolls from more UV to […]

New Science 24: Is that one new Solar force, or two? The Force-ND Hypothesis

Is Force X two different forces? The Sun could influence Earths climate through magnetic fields, solar particle flows, or spectral changes. | Image: ESA

There are two key clues, almost contradicting each other, which we must solve to figure out what Force X is. How do we explain that mysterious pattern — the little spike of extra sunlight each sunspot cycle doesn’t warm the Earth as it arrives — and it should. Instead, the warming appears greatly amplified 11 years later (or one sunspot cycle later). What’s going on? Logically the sunlight itself is not the direct cause, but only a signal, a leading indicator of something else going on — perhaps the solar wind, the magnetic fluxes, or the changes in the UV-Infra Red spectrum. Any one of these (or all of them) or maddeningly, even something else, could be influencing cloud cover on Earth — and some action on clouds is by far the most likely mechanism to amplify the solar effect. They blanket 60% of Earth, and small changes make large differences. We live on a Water-Planet. So having looked at the reasons for Force X, we now split it into two different forces (N and […]

What’s going on with the Sun?

In the last post in the climate research series we described David’s major finding that changes in total sunlight lead Earth’s temperature by one sunspot cycle. But what’s going on with the Sun — what is the mechanism? In this post David lays out four puzzling clues about solar influence on our global temperature, then puts forward a hypothesis. What force (or forces) are required to resolve all these odd points?

To recap: Both his Fourier analysis and many independent papers suggest there is a delay between total solar irradiation (TSI) and global temperature. David reasoned that the delay is a true delay, not just a smoothing effect while increased heat propagates around the planet. Because the timing is so tied to solar cycles, the trigger for the delay must start on the Sun, not on the Earth. This is not just a case of our oceans slowly absorbing the extra energy from the Sun — and there simply isn’t enough, in any case. Something quite different […]

New Science 22: Solar TSI leads Earth’s temperature with an 11 year delay

We’re launching headlong back into the New Science series with a major post

Lots of things will fall into place — as befits a potential paradigm step forward. For decades, people have been looking to see if the Sun controlled our climate but the message was perplexingly muddy. In the long run, solar activity appears linked to surface temperatures on Earth. (Solar activity was at a record high during the second half of the 20th century when temperatures were also high.) But when we look closely, firstly the solar peaks don’t exactly coincide with the surface temperature peaks, and secondly, the extra energy supplied during the solar peaks is far too small to do much warming. So how could changes in surface temperature be due to the Sun?

A few researchers noted an esoteric correlation of long solar cycles with lower temperatures in the next solar cycle, but mostly those papers were left on the shelf, ignored. Dr David Evans’ notch-delay solar delay theory can explain this odd pattern.

To unravel the connections David took a new approach which cleared out the dead-end complexity of the current climate research. Instead of trying to predict everything from a bottom […]

New Science 21: The mysterious Notch in the Sun-Earth relationship — the dog that didn’t bark

The notch in the Sun-Earth relationship is the dog that didn’t bark — the clue that was there all along, telling us something about the way the Sun influences Earth’s climate. There is a flicker of extra energy coming in at the peak of every solar cycle — roughly every 11 years. It’s only a small peak, but there is no warming on Earth at all — it’s like the energy that vanished. A good skeptic would be saying but, the increase in energy is so small, how could we find it among the noise? And the answer is that Fourier maths is so good at doing this that it is used every day to find the GPS signals which (as David details below) are so much smaller than the noise that they are much harder to find than this signal from the Sun.

Thousands of engineers know about and use Fourier maths and notch filters, but due to a strange one-sided bureaucratic funding model, none of those thousands of experts have applied that knowledge, which is so well adapted to feedback systems to the Sun Earth energy flows. David has used an input-output “black box” method to find […]

New Science 20: It’s not CO2, so what Is the main cause of Global Warming?

We are back in the hunt for the main mystery drivers of our climate. The IPCC says it can’t be the Sun because the total amount of sunlight barely changes. Which is the usual half-truth that pretends the Sun is simple a ball of fire with no magnetic field, no solar wind, and has no changes in the “color” of the spectrum it emits. But the Sun has a massive fluxing magnetic field that turns itself inside out and upside down regularly, it churns off a stream of charged particles that rain on Earth, and if human eyes could see infra red and UV, we’d see the color of the Sun change through the cycle. We are only just beginning to figure out how these aspects affect the climate. But we know these factors influence ozone, probably cloud seeding, and possibly jet streams.

The only good long data we have on the Sun are the sunspots, which give us a reasonable idea of total sunlight since 1610. David uses Fourier maths to find the way that total solar irradiance (TSI) might relate to temperatures on Earth. TSI itself barely changes, so it could only have caused about 10% of the […]

New Science 19: The invisible nameless model that controls the whole field of climate science

Don’t underestimate the importance of the nameless basic model. It sounds small, but in the culture and philosophy of climate science it’s bigger and carries more weight than the massive hairy GCMs. Like an invisible gossamer web, it’s overarching. It spans and defines all the other models. When they produce “dumb” answers, the basic model holds them in, for thou shalt not stray too far from the climate sensitivity defined by the basic model. It defines what “dumb” is. (It’s just “basic physics” after all.) One model to bind them all. What could possibly go wrong?

A lot, apparently. The physics might be right, but the equations are calculating imaginary conditions. The answers might be arithmetically correct but useless at the same time. They miss the real route that energy flows through to space.

By definition, as long as the basic model is wrong, the GCM models can never get it right.

It’s not like climate scientists consult the oracle of the basic model every day, or even once a year… they don’t need to. They were taught it their climate larval stage, often long before they’d written one paper. The basic model shows that the warming of […]

New Science 18: Finally climate sensitivity calculated at just one tenth of official estimates.

Image: NASA

In years to come it may be recognized that this blog post produced the first modeled accurate figure for climate sensitivity. Equilibrium Climate Sensitivity sounds dry, but it’s the driving theme, the holy grail of climate science. The accurate figure (whatever it is) summarizes the whole entirety of carbon dioxide’s atmospheric importance. That number determines whether we are headed for a champagne picnic or a baking apocalypse.

To calculate a better estimate, David identified the flaws of the conventional basic model, and rebuilt it. The basic climate model is the top-down approach looking at inputs and outputs of the whole system. It defines the culture and textbooks of the modern global warming movement. GCMs (the big hairy coupled global models) are bottom-up approaches, doomed to failure by trying to add up every detail and ending up drowning in mile-high uncertainty bands. But the GCMs are ultimately tweaked to arrive at a similar ballpark climate sensitivity as the textbook model for the “basic physics” dictates. Hence this core model is where the debate needs to be. (Everyone knows the GCMs are broken.)

For decades the world of conventional climate research has been stuck in a groundhog day […]

New Science 17: Solving the mystery of the missing “Hot spot”

Things are hotting up. After all the hard work of the past few posts, the payoff begins. By solving the flaws inherent in the basic conventional model we solve some of its biggest missed-predictions. And the clincher for conventional models has always been the missing hot spot. Without it, over half the projected warming just vanishes. And if it is telling the tale of a negative type of feedback instead of a positive one, then all bets are off — not three degrees, not even one degree, it’s more like “half” a degree. Go panic about that.

Here David gets into the empirical data — the radiosondes, the satellites, and shows how his model fits their results, whereas the establishment models have repeatedly been forced to deny them. Twenty eight million radiosondes get the wrong results: how many ways can we adjust them? Tweak that cold bias, blend in the wind shear, change the color-scales, homogenize the heck. Smooth, sort, shovel and grind those graphs. The fingerprint of CO2 was everywhere in 2005, though gradually became the non-unique signal of any kind of warming, but it still wasn’t there. It kept being “found”, though it was never reported missing. […]

New Science 16: Building the alternative model and why it solves so many major problems

In typical style I looked at this draft and told David that the second half of his post should be at the top (that’s where he discusses how his model solves so many problems). He replied that the equations were the most important part, and he wasn’t going to flip them around. So, for readers who don’t speak mathematica-lingua, all I can say, is don’t miss the second half below.

Also in typical style, David prefers this picture he’s just drawn in his diagramming software, to my cartoon in the intro to post 11:

 

In this post, David combines the two smaller models to make one basic climate model (that’s the sum-of-warmings and the OLR models). Unlike the mainstream conventional basic model that underlies the entire establishment culture and philosophy, the alternative model uses more empirical data (and from the real world too, not just the lab). It’s also less reliant on hypothetical partial derivatives. Plus, in the alternate model, different forcings can cause different responses. In the conventional model, the architecture assumes the climate responds to to all forcings the same way.

CO2 has a warming effect on the atmosphere, rather than just on the surface, […]

New Science 15: Modeling outgoing radiation (OLR)

OLR — outgoing longwave radiation — is so key, so central to the climate debate that if we had top notch data on the radiation coming off the planet, we would have solved the effect of extra CO2 a long time ago. That we don’t have a specific satellite monitoring these changes in detail is like the dog that didn’t bark. Apparently a specialist OLR satellite was to be launched in 2015. More info on the RAVAN Satellite here (was supposed to launch in Sept 2015). (UPDATE: Planned for 2016) h/t siliggy.

There are four main pipes to space, and in David’s work each pipe is considered separately. The conventional model assumes that increasing atmospheric CO2 constricts the CO2 pipe, which warms the surface, causing more evaporation, which then constricts the Water Vapor pipe (this is the “water vapor amplification”, even more constriction of radiation to space by water vapor that forces the surface to emit more by being yet warmer). But the missing hot spot tells us that this theory is wrong. In this OLR model, the water vapor pipe could either expand or constrict. An expansion means a drop in the height of the emissions layer, […]

New Science 14: Greenhouse Emission Layers — which pipe is the biggest?

Here we get into the nitty-gritty (as much as we can) of the energy coming off the planet. Looking at the spectrum of outgoing infrared we can learn a lot from the Nimbus data. In the graph below we can see a lot more energy comes from certain wavelengths, and given that the curve would follow the “grey” shape if it was a single body emitting, we can also see how some “pipes” are blocked.

The CO2 band shows a large obvious indentation, but don’t be fooled, most of that curve looks the same at much lower concentrations of CO2. As CO2 levels rise in our atmosphere there is little effect on the radiance of the coldest parts of the CO2 band, what changes is in the “wings”.

The hotter a thing is, the more energy it radiates, so in this graph the higher amounts of OLR (outgoing longwave radiation) are coming off the warmer surface or air closer to it. Turn things upside down in your mind, the high readings come from low-altitude places which are warm (like the surface), and as the readings get lower in radiance, they must be coming from colder spots at higher altitudes. […]

Lucia has a bad week on partial derivatives

We welcome collaboration, but empty, uninformed ill-will doesn’t help the unresourced skeptics to beat the billion dollar green machine. It’s time for Lucia to admit she got it wrong. Lucia’s second post failed to clarify anything. She didn’t acknowledge that she had not found a single real mistake David’s work, nor did she apologize for getting so much wrong. Having decided everything David was doing was “crud” after reading two paragraphs, she now has the onerous and pointless task of trying to defend a hasty uninformed position.

Lucia didn’t have to dig the hole deeper but she tried. To turn her mistaken accusations into something useful she transparently shifts the goals and won’t join the dots. Evans was critiquing Held, Soden, and Pierrehumbert. He described how they relied on partial derivatives of dependent variables, impossibly holding everything else constant in climate and thereby incurring unknown errors. Lucia now says “but they could’ve done it a different way without them” and perhaps hopes no one notices the unspoken admission that David Evans was right.

The bizarre thing is that you don’t need a maths degree to know her method is silly on its face. In […]

New Science 13: The Start of a New Architecture for Climate Models

In most ways, David Evans’ alternative model is exactly the same as the conventional model. But a reconnection of one forcing, and an additional factor, can make all the difference. Finally, climate model architecture is getting analyzed and discussed — the conventional structure has been in place for over 40 years.

In the conventional basic model the radiation imbalance caused by CO2 is treated like extra sunlight, amplified by the same feedback processes that amplify warming caused by the sun. But as we explained, the effects of CO2 are not just confined to the surface of Earth, but spread through the atmosphere. In the alternative model the warming caused by CO2 is allowed to have its own unique response. Only after the separate “warmings” of the Sun and CO2 are calculated can they be added together. The conventional model adds them too soon, while they are still radiation imbalances, and assumes the Earth’s climate responds to both in the same way — it’s too simplistic.

David’s model also allows for other factors to change cloud cover, with the addition of an input for externally driven albedo (EDA). In conventional models, clouds are just a feedback to surface warming, […]

New Science 12: How do we model the thermal inertia of the Earth?

Basic models take a top down approach, focusing on gross input and output rather than all the details within the system (which is mainly left to the feedbacks parameter). This makes them very different to the GCMs, which attempt to add up the climate from the bottom up and predict based on adding up grids and guesstimates of clouds, humidity, ice, etc.

The energy coming in to the Earth is called absorbed solar radiation (ASR). It varies significantly. The Earth will absorb the peaks and troughs of this to a certain extent. If we step back and look at the big picture, the question is how many years does it take for a step up in incoming energy to spread its way through the climate system, vanish into the top layer of the ocean, come back out and be released to space. To some extent that extra energy gets absorbed for a while before being released. David analyzed this system from the outside, graphing it like a low pass filter in electronics. (How much “noise” of spikes and troughs in ASR is being smoothed out by the Earth’s climate?)

In a […]

New Science 11: An Alternative Modeling Strategy

All pipes lead to Space

Inexorably, energy is headed for the coldest vacuum. It’s just a question of how long and what path it takes to get there. On Earth there are four main “pipes” to space — the CO2, water vapor, cloud tops, and surface pipes (see post 6). The basic establishment model treats “trapped” heat as if it were “adding heat” (see post 9). But partially blocking one exit pipe out of four is not the same as adding energy to the incoming pipe. Adding more energy on the incoming side means the total outflow must be higher. But merely slowing the outflow in one pipe means the total outflow remains the same, it just redistributes itself among the four outflow pipes.

David is proposing a paradigm shift in how a basic climate model is organized. This post is a road-map for building an alternative model.

The current paradigm starts from the assumption that reducing the outflow in one pipe is equivalent to the effect of increasing the inflow on the single incoming pipe — it is a radiation balance, where all imbalances are equivalent regardless of origin. Doubling CO2 is “equal” to 2% […]

Lucia has a bad day with partial derivatives

Here’s a lesson in when to post and when to email. Over at the Blackboard, Lucia couldn’t make sense of David Evans’ post on partial derivatives, but instead of emailing us or commenting here, she published her unresearched thoughts and and asked her readers instead. Only most of them didn’t know either and it didn’t help that the quotes were misattributed, and Lucia’s assumptions were wrong. Together they generated a thread of fog, arguing about irrelevant points in maths and models that didn’t apply. Having admitted that she is confused about what David was saying, in comments she went ahead and called him confused, declaring he didn’t understand maths, and was spouting nonsense. (Steady on Lucia.) In the nicest possible way David explains he’s right, she’s wrong. And he had defined and cited everything correctly too (it was all in the post, or linked to it).

Her post is titled: “Questions to David Evans: What do you mean about partial derivatives?”. Lucia had my email, but posted: “I’m hoping David or readers who understand his point can clarify for me”. However she didn’t email us after that either. So by the time I tripped over […]

New Science 10: Whatever controls clouds controls the climate

How much sunlight makes it to the surface?

We all know how powerful clouds are. Just stand outside on a patchy day — feel the goosebumps. These megaton floating conglomerates of water act as vast shields — they cover 60% of the surface of Earth, and even a small change makes a big difference. While changes in the total amount of direct sunlight coming off the sun are very small, the changes to the amount of reflecting surfaces floating above Earth are, proportionally, at least twice as large, and possibly much much more influential. The IPCC includes changes in sunlight (TSI), so it does not make sense to ignore the larger and more powerful changes in the Earth’s albedo (fraction of sunlight that is reflected) due to “external” factors (due to factors other than feedbacks to surface warming). Both contribute to the amount of sunlight heating the surface, or “absorbed solar radiation” (ASR) (before feedbacks).

There are lots of reasons clouds might change that are not included in standard climate models. Just for starters — cosmic rays may seed cloud formation. Aerosols released by plants, plankton and marine life do — some aerosols are included, […]

New Science 9: Error 3: All Radiation Imbalances Treated the Same — The Ground is not the sky!

The ground is not the sky

Here’s a big big flaw that is easy for anyone to understand, yet has lain at the core of the climate models since at least 1984. Indeed, you’ll wonder why we all haven’t been chuckling at this simplistic caricature of our atmosphere for 31 years.

The theory underlying the alarm about CO2 is built around a bizarre idea that blocking outgoing energy in the CO2 pipe is equivalent to getting an increase in sunlight. The very architecture of all the mainstream climate models assumes that the Earth’s climate responds to all radiation imbalances or “forcings” as if they were all like extra sunlight. (We call that extra absorbed solar radiation (ASR) to be more precise. It’s all about the sunlight that makes it through to the surface.)

Extra sunlight adds heat directly to the Earth’s surface, and maybe the climate models have correctly estimated the feedbacks from clouds and evaporation and what-not to surface warming. But it is obvious, in a way even a child could comprehend, that this is not the same as blocking outgoing radiation in the upper atmosphere, which is the effect of increasing CO2. […]

New Science 8: Applying the Stefan-Boltzmann Law to Earth

Energy is emitted to space from many different heights in the atmosphere, depending on the wavelength (not to scale, suggestive only).

One more quick post of mostly uncontroversial foundation for the math-and-physics-heads among us. But it’s a must for anyone who wants to talk Stefan-Boltzmann and follow the details of the next posts. My intro here, just has the gist without the equations.

Mostly the IPCC will agree with this post, but they might be a bit snooty that David thinks their “effective temperature” is too much of an approximation conceptually, and the slightly more complicated idea of a “radiating temperature” is needed. Strictly, the effective temperature idea treats Earth like it is a black-body at infrared, which it isn’t really. Earth is almost a black-body, but not quite.

There is no single layer that radiates to space, instead emissions come from many different heights, depending on the wavelength. We could average the emissions into “one layer”, but doing that would lose detail that matters when computing sensitivity to increasing CO2.

Technically the Stefan-Boltzmann law is not supposed to be applied to Earth, because there is no single physical radiating surface […]
