What statements? I just wanted to know if Dog was familiar with basic equations, that is all. αln(C/Co) is a simple equation to measure the change of energy in the atmosphere due to CO2 emissions. It is nothing more, it is just basic climate change science. I already explained the variables. I don't know what else you want me to demonstrate. Do you have a specific question?

Doc? I am ready to go and I won't be available for many days. Last chance.

I will quote myself again

DT,

This is how my reasoning went:

Doctor CamNC4Me wrote:
DoubtingThomas wrote:and please explain in your own words why Lindzen's arguments are so compelling.


Dude. You're the one that dropped that alphabet equation on us. Explain it. Otherwise you risk looking like a poseur.

You then claim you answered it when you posted your ppm question. That didn't answer the above original challenge to answer why Lindzen's arguments are so compelling because *equation*.

So, I wanted to explain what each part of the equation meant in context of the thread. You haven't done that. Instead you posted this bizarre breakdown of parts of the equation:

DoubtingThomas wrote:C is CO2 in ppm

Co = 278 ppm

ln = learn it in 8th grade math.

Radiative forcing is the difference between the sunlight absorbed by the Earth and energy radiated back to space. Radiative forcing is used to compare man-made and natural drivers of climate change . Can you tell me what is ln?


When I plugged your breakdown of the equation back into the equation it didn't make sense, hence my wtf does that even mean?

So, I wanted you to give an example of what each component of the equation means, and then I wanted to do the math explaining why you're inputting whatever metric into the equation in order to support my original challenge noted above.

1) input data into each component which illustrates your understanding of how the equation works

2) explain the data you're inputting into the equation

3) explain what each data point means and why you're doing it

4) demonstrate how that relates to your claim as to why it makes sense

Once you've demonstrated your grasp of the equation as it relates to this thread, then you can make an argument that whatever formula you provided to determine when we reach x-ppm we're going to experience y-thing.

In other words, I don't understand the practical use of the equation related to this thread, and since you're the one that posted it, in an attempt to teach those who're ignorant of whatever point you're attempting to make, the onus is on you to provide an example or two of the equation in use in order to make a point, which I'm hoping you actually do.

I'm not sure how you are expecting me to respond? Lindzen is a credible guy that offers a compelling argument. Doesn't appear you read his lecture at all.

I did. However, based on many of your other posts, I’m not thinking that you have read it yourself except in the most cursory manner. You seem to be thinking you’ve found some sort of irrefutable counterargument to concerns over anthropogenic climate effects by presenting one curious statement:

One of the points he makes, playing into his overall argument, that CO2 is plant food, is not in dispute. Your links don't dispute this simple truth, either.

So, “CO2 is plant food”. That’s nice. But, compelling? Hardly. Can you tell me what that has to do with CO2 having other adverse effects to, say, climate and sea level change? You know, the things that we’re actually discussing in this thread? Or did you lose focus?

They attempt to argue excessive CO2 levels can be bad, but it's hardly a settled matter and merely a theory on their part. CO2 will give rise to weeds and such that will affect other plant growth in a negative way. So the theory goes. There isn't any kind of settled answer on how this would play out or when CO2 levels would become problematic.

OK, now you’re backsliding a bit and acknowledging that your heady optimism about CO2’s potential to make plants fat & happy might not work out as a net beneficial outcome to a given ecosystem anyway. That’s a start, at least. And it’s basically what I was pointing out with those links, earlier.

So, while I’m at it, I’d also like to point out a few other realities.

1. People generally don’t eat grasses and leaves. We eat the substantial, seed-y and fruity parts of plants, given that much of a plant’s mass isn’t directly digestible by our own systems. Don’t believe me? Go eat a log, then return and report. And the tasty parts of plants don’t increase in direct proportion to overall growth. So even if increased CO2 might make a plant slightly happier and more massive by, say, 10%, it does not follow that it necessarily produces 10% more edible food. That’s basic plant biology, there. Look it up.

2. ‘More food’ isn’t necessarily a magic bullet anyway. It takes more than just an increase in CO2 to guarantee better plant results. CO2 is just one component in a larger picture. The way you present this argument is no different than arguing that feeding a person 10 hot dogs a day is always better than feeding him 5. That ain’t how it works. Look it up.

3. A few other things are also good for plants. Stuff like the crap that comes out of your ass, for example. In fact, it’s quite accurate to state that if you were to drop dead while tending your garden and no-one noticed for a long enough time that you began to decompose there, that the plants would react quite favorably to all of the ‘food’ that they were suddenly inundated with. Note that even though these things are good for plants, humans still find it wise and practical to, say, regulate where they dump their crap and have taken to carefully processing it instead of mindlessly polluting their surroundings with it. And no-one that I know of sees the plant-human corpse relationship as beneficial to the human.

Which leads to the point. That being, that the argument over excess CO2 really has nothing to do with plants. No one is worried about your pet cactus. We don’t give a crap about the geraniums on the front porch. The argument has to do with people, and how they are affected. And having a 10% better yield of blueberries or avocados means very little to the 80% of humanity that lives close enough to the shorelines throughout the world to be vulnerable to the full range and cost of property loss, infrastructure destruction, and economic disruption that even a relatively mild rise in sea level can bring.

Seriously, please go find a real counterargument, if you feel you need to keep acting as a tool for the denialist cohort. Otherwise, the lame talking point that you’re relying upon now just sucks.

I don’t know about the smart part, but I’ve been following climate science for over 20 years and doing my best to understand it. I think you listed what the variables are, but I don’t think you explained what the equation means and what it represents in the real world. Some folks can just look at an equation and understand what it means in the real world. I am not one of those people. I need more than just a definition of the variables to really understand an equation. If I hadn’t understood what radiative forcing was already, I don’t think your explanation of the equation would have helped me.

Does that make sense?

Morning, boys. Ok, here we go. Rep, I didn't intentionally omit anything. I didn't omit anything at all, I pasted it as I found it quoted elsewhere. If something has been misrepresented, that's a completely valid point to bring up and I won't condone the behavior. Is this a case of something being misrepresented? Pulling up the article, I don't think so, and don't see what you're getting worked up about.

Here is the full quote.

Our results suggest that as CO2 accumulates in the atmosphere, the full warming effect of an emission may not be felt for several decades, if not centuries. Most of the warming, however, will emerge relatively quickly, implying that CO2 emission cuts will not only benefit subsequent generations but also the generation implementing those cuts.


What does "relatively quickly" mean?

I didn't read every word, but I scanned though the article reasonably well. It presents the results of several different models that forecast the warming effect of an emission over time. Different models yield different results.

For a 100 GtC pulse of CO2 released into the atmosphere with a background CO2 concentration of 389 ppm, R&C found the median time between an emission and maximum warming to be 10.1 years, with a 90% probability range of 6.6–30.7 years


For pulse emissions of 1000 GtC, the double-peak shape remains but is less pronounced and the maximum warming occurs 31 years after the emission. For very large pulses (5000 GtC), the first peak disappears due to the decline in ocean heat uptake overwhelming the radiative forcing decline. In this case, the maximum warming occurs 785 years after the emission


A large fraction of the warming, however, will be realized relatively quickly (93% of the peak warming is realized 10 years after the emissions for the 1000 PgC pulse). This implies that the warming commitment from past CO2 emissions is small, and that future warming will largely be determined by current and future CO2 emissions.


So, at best, "relatively quickly" means ~decade after the emission. Now what did I say?

Isn't that convenient. A theory, output from a model, which cannot be tested or disproved. Something something, scientific method.


The article completely supports my point. All the doom is based on computer models. Models which remain untested, the excuse for which is a huge time lag. And that isn't to say this isn't the truth of the situation. The models could be accurate, although they can't all be accurate, but there could be an accurate one in the mix somewhere. But if there is no way to test the models until decades down the road, that's a problem. A big problem. It's not good science to base real-world decisions on faith. As an engineer, if I made decisions like that I'd be thrown in jail. The idea of upending the world's economy on the current body of work is patently irresponsible.

https://www.nspe.org/resources/ethics/code-ethics

Tell me, how many of these academicians would be willing to subject themselves to prison if wrong? Even in engineering disciplines, the answer is not many. Relatively few engineers in academics have PE licenses or do work that would be subject to such licensing restrictions. They are theoreticians. The'll come up with theories and spend decades nerding out together sussing through the results. I propose we create something like a PE licensing for climatologists, which imposes strict evidence-based standards. Moreover, that these people be held liable for damages they cause. Just like an engineer who designs an unsafe system that results in someone's death, or which results in monetary damages. If I design a control system that brings down someone's plant, oops, my ass is in big trouble. Just like a doctor, I have to maintain liability insurance. If we spend $XXX billions of dollars on "carbon credits" or whatever, because this person predicted that the earth's temperature would rise YYY degrees, but then it doesn't happen - who is held responsible? CO2 levels went up anyway, because China, and oops, temperature didn't rise, the tornados didn't happen, well well well, the person or people who made these predictions should be subject to the same penalties that a PE would. Which is CRIMINAL LIABILITY.

I'm happy to get into the weeds with you, we can turn this into a megathread and start going through the fine details of climate science from beginning to end if you'd like. But I'm not a climatologist. All I can do is state why I am or am not persuaded by a certain argument. My position can be changed, if the data is compelling. But I will not compromise my basic standards, which are high. Just like evolution, or theoretical physics such as string theory, a global warming apocalypse may be a "good" or even the "best" interpretation of the current body of climate science, but that doesn't mean it crosses a credibility threshold that justifies the sort of actions recommended by the IPCC.

This right here is precisely what needs to happen. This should not be a lamentation on the part of researchers. They should be pushing for this. They should WANT their work to be born our by empirical results. They should want huge life and death altering decisions to be based on actual knowledge rather than a highly theoretical inquiry.

Moreover, there is the matter of practicality. For sake of argument let's say the doom is real. The most apocalyptic of predictions is accurate. Does it make sense to march into Afghanistan and try to impose democracy? No, this is naïve and idiotic. If the apocalyptic doom is for realz, and we KNOW it to be for realz, our whole approach is wrong. Nobody else will comply. Period. Let's get real. We are better off making as much damn money as we can, throwing as much money towards research and tech as we can. Capping our carbon production is completely and totally idiotic.
