E.M. Smith explains Curing Radiation Myopia Regarding Climate<\/strong><\/h5>\n\n\n\n

E.M. Smith provides an helpful critique of a recent incomplete theory of earth\u2019s climate functioning in his Chiefio blog post\u00a0So Close\u2013Missing Convection and Homeostasis<\/strong><\/a>. Excerpts in italics with my bolds and added images.\u00a0 The reference is to a video by Sabine Hossenfelder you can view below in the post.<\/p>\n\n\n\n

It is Soooo easy to get things just a little bit off and miss reality. Especially in complex systems and even more so when folks raking in $Millions are interested in misleading for profit. Sigh.<\/mark><\/strong><\/em><\/p>\n\n\n\n

Sabine Hosenfelder<\/strong> does a wonderful series of videos \u2018explaining\u2019 all sorts of interesting things in and about actual science and how the universe works. She is quite smart and generally \u201cknows her stuff\u201d.<\/strong> But<\/strong>\u2026 It looks like she has gotten trapped into the Radiative Model of Globull Warming.<\/strong><\/em><\/p>\n\n\n\n

The whole mythology of Global Warming depends on having you NOT think about anything but radiative processes and physics.<\/strong> To trap you into the Radiative Model. But the Earth is more complex than that. Much more complex. Then there\u2019s the fact that you DO have some essential Radiative Physics to deal with, so the bait is there.   <\/strong>However\u2026<\/em><\/p>\n\n\n\n

It is absolutely essential to pay attention to convection in the lower atmosphere
and to the \u201cfeedback loops\u201d or homeostasis in the system.<\/mark><\/strong><\/em><\/p>\n\n\n\n

The system acts to restore its original state. There is\u00a0NO \u201crunaway greenhouse\u201d or we would have never evolved into being<\/strong>\u00a0since the early earth had astoundingly high levels of CO2 and we would have baked to death before getting out of our slime beds as microbes.<\/em><\/p>\n\n\n\n

OK, I\u2019ll show you her video. It is quite good even with the \u201cswing and a miss\u201d at the end. She does 3 levels of The Greenhouse Gas Mythology<\/strong> so you can see the process evolving from grammar school to high school to college level of mythology. But then she doesn\u2019t quite make it to Post-Doc Reality.<\/strong><\/em><\/p>\n\n\n\n

Where\u2019s she wrong? (Well, not really wrong, but lacking<\/strong>\u2026)<\/em><\/p>\n\n\n\n

I see 2 major issues. First<\/strong> off, she talks about the \u201clower atmosphere warming\u201d<\/strong>. Well, yes and no. It doesn\u2019t \u201cwarm\u201d in the sense of getting hotter, but it does speed up convection to move the added heat flow<\/strong>.<\/em><\/p>\n\n\n\n

In English \u201cheating\u201d has 2 different meanings. Increasing temperature.
Increasing heat flow at a temperature.<\/mark><\/strong><\/em><\/p>\n\n\n\n

We see this in \u201cwarm up the TV dinner in the microwave\u201d meaning to heat it up from frozen to edible; and in the part where the frozen dinner is\u00a0defrosting at a constant temperature as it absorbs heat but turns it into the heat of fusion of water.<\/strong>\u00a0So you can \u201cwarm it up\u201d by melting at a constant temperature of frozen water (but adding a LOT of thermal energy \u2013 \u201cheat\u201d) then later as increasing temperature once the ice is melted. It is very important to keep in mind that there are 2 kinds of \u201cheating\u201d. NOT just \u201cincreasing temperature\u201d.<\/em><\/p>\n\n\n\n
