California. By the 1973 Arab Oil Embargo, I had already done work with wind energy systems and moved back into a University environment studying energy. At the time, the US electric system was growing at around 7% a year, an exponential rate which gives a doubling time of 10 years. At that rate of growth, the entire US electric system was being duplicated over a 10 year period and over the next 10 years, the whole mess would need to be doubled again. The conventional thinking was that that rate would continue, thus there was a scramble for energy sources to meet the expected demand. There were serious projections that by the year 2000, there would be 1000 nukes in operation. Of course, things didn't turn out that way, which just shows how difficult it is to look forward. One major problem with the AGW situation is the future projections of emissions, as you note. I think the RCP 8.5 scenario isn't likely, but it does represent what could happen if the rest of the world were to follow the developed world's path going forward, given that there are still a couple of billion people who have no access to electricity while the population is set to reach 10 billion by 2050. We can only hope things don't turn out that way because the resources aren't likely to be available and the environment is already in serious trouble on many measures.<br /><br />There are those of us who think humanity is headed for a dieoff because our governments aren't willing to face the reality of finite limits. Both the liberal, free market systems and the few remaining centrally planned (aka: communist) economies are failures in this regard. If humanity can't put the brakes on population growth, neither type of government can solve the problem except by unleashing the same 4 horsemen which have appeared throughout history as civilizations collapsed...E.

Neither do I question the fact that the energy level in the biosphere is increasing, or that surface temperature increases. I started studying the subject in the early 1990's when I was working as a supervisor in an Arctic project. My job included establishing the methods we would use to set the design basis for ice capable vessels and ports (I'm a published author in the subject in Russian). Later after I retired I started reading about the subject, and it seemed to me it was being mishandled. <br /><br />I gave the typical doubts about TCR because a couple of friends who worked with me in the 1990's told me they felt it was closer to 1.6. These guys are hard core professionals who worked for me and I don't think they have an axe to grind. I also have very sound objections to the "business as usual" RCP8.5, which I found to be a very trashable piece of work (my team started doing system dynamics around 1991, so I'm familiar with the way those IAMs are built). <br /><br />I'm also doing adhoc research on the link between global warming and the international communist Mafia. And it sure looks like they are linked. Every time I scratch a "Warmist" I get a red coating under the green surface. For example, over the last couple of days I scratched Willard and out popped out a raging red defending communism and quoting all sorts of provenezuelan dictatorship trash. Talking about Venezuela, yesterday was a big day, General Attorney Luisa Ortega declared the designation of over a dozen Supreme Court judges by the Maduristas in December 2015 was spurious and invalid. The Maduro dictatorship has relied on the fake Supreme Court judges to execute the self coup and install a tyranny. These are now disarmed, and it looks like the risk of civil war is increasing every day as the dictatorship elite fractures into at least two factions. Maduro's push into full dictatorship mode was encouraged by Obama when he acted so chummy with Raúl Castro. <br /><br />Meanwhile in Cuba the resistance sent out a series of messages describing how Raúl Castro was extremely ill, and his eldest son was maneuvering to keep the Castro Dinasty in power. Their plan is to have Diaz Canel, who is married to Raul's granddaughter, take over as nominal head of state but have Raul's eldest son Alejandro in charge of all security and intelligence services. Raul's grandson Raulito would be in charge of the body guards who defend the nomenklatura from the people, as well as the special medical service reserved for the dictatorship's upper caste.

For a radiative transfer calculation, you aren't going to want CO2 measured in ppm - you will need it in some absolute units.<br /><br />The inert ingredients become a distraction when they are included as the denominator in the calculation of ppm (=quantity we really want/inert ingredients that don't matter). That's one of the main points of Eli's post: when you look at what is actually in the numerator and ignore the denominator, it turns out there is a lot of CO2 floating around.Bob Loblawhttps://www.blogger.com/profile/11643980587768003219noreply@blogger.comtag:blogger.com,1999:blog-16612221.post-26460628923467300292017-06-12T16:13:54.833-04:002017-06-12T16:13:54.833-04:00ESwansonL

It's like saying inches or meters aren't important, it's the distance that counts, but you have to measure the distance to measure any change in it. For CO2 in the atmosphere we do that by measuring ppmv over time.<br /><br />"Adding or subtracting from the inert ingredients does not change the radiative transfer process." <br /><br />Again, agreed, but talk of adding or subtracting the inert ingredients (O2 and N2) is a distraction here since we are not doing that with O2* and N2. (Actually we are through combustion, but it's negligible since the change is very small and the reservoir is very large.) The only reason to remove 3 and then 1 liter of water from the pool is simply to keep the total volume the same and make the ink concentration 300 ppmv and then 400 ppmv. And the sloping bottom of the pool just provides a handy measurement of how adding more ink will shorten the mean free path of visible light through the water.Jim Eagerhttps://www.blogger.com/profile/10448459024892788259noreply@blogger.comtag:blogger.com,1999:blog-16612221.post-9315532461334995152017-06-11T20:37:57.926-04:002017-06-11T20:37:57.926-04:00"has no analog to what is happening in the at...<i>"has no analog to what is happening in the atmosphere"</i><br /><br />The point is that the concentration is not the important factor - it is the amount.

And if you had two beakers of different diameters, both with 280ppmm the larger beaker would look darker - because more water * 280ppm ink means more ink in total.Bob Loblawhttps://www.blogger.com/profile/11643980587768003219noreply@blogger.comtag:blogger.com,1999:blog-16612221.post-25548627925140521612017-06-11T18:21:51.873-04:002017-06-11T18:21:51.873-04:00https://www.youtube.com/watch?v=81FHVrXgzuA pretty...https://www.youtube.com/watch?v=81FHVrXgzuA pretty much answers the ink in the pool question. 280 and 560 ppm in the waterEliRabetthttps://www.blogger.com/profile/07957002964638398767noreply@blogger.comtag:blogger.com,1999:blog-16612221.post-27039342110957662562017-06-11T14:16:28.091-04:002017-06-11T14:16:28.091-04:00"I think we are on the same page.”
Perhaps, ..."I think we are on the same page.”<br /><br />Perhaps, but halving the volume while leaving carbon black (or CO2) the same has no analog to what is happening in the atmosphere.

Just as the ppm CO2 is not the issue, it's the absolute amount of CO2.<br /><br />As for the swimming pool: if it did not have a shallow and deep end, then the same amount of carbon black in half the amount of water would have an identical screening effect. In the case where the pool changes depth from one end to the other, the point at which you cannot see the bottom will be the point at which the pool is half the depth from before. At this point, the total carbon black will be the same as it was for the full pool: <br /><br />--- same carbon black (entire pool) * half the water = twice the concentration<br /><br />---twice the concentration * half the depth = same visibility reduction.<br /><br />I think we are on the same page.Bob Loblawhttps://www.blogger.com/profile/11643980587768003219noreply@blogger.comtag:blogger.com,1999:blog-16612221.post-82039443350188176182017-06-10T09:36:17.907-04:002017-06-10T09:36:17.907-04:00For Bob Loblaw,
