Uuuuuh, das #ZDF verbaut #Clausius & #Clapeyron in eine beiläufige Infografik.
#Gewitter und #Starkregen haben in #Hessen, #Thüringen und #Bayern schwere #Schäden verursacht. Viele Keller und Straßen wurden überflutet, und Einsatzkräfte mussten zahlreiche Menschen retten. Der #DWD warnt vor weiteren Unwettern.

"Everyone knows that heat can produce motion"
#Carnot still believed in caloric theory (where heat is a fluid). His one-and-only book (1824) was not an initial success, but #Clausius knew of it some 40 years later prior to formalizing the concept of #entropy.
I tried to see if and how Carnot found the efficiency equation eta = 1-Tc/Th. Not so clear to me, although he does talk about the trends. Does someone know?
Die #Clausius-#Clapeyron-Gleichung als #Katastrophenformel: trotz des etwas reißerischen Titels ein sehr verständlicher Beitrag von @rahmstorf über #Lufttemperatur, #Wasserdampfgehalt der Luft, Dampfhunger (vapor pressure deficit) und relative #Luftfeuchtigkeit und wie diese Zusammenhänge durch die Erderwärmung zu vermehrter #Dürre und ebenfalls zu #Extremniederschlägen führen:

Hay como para jugar hasta que llegue el 108, el 161, el 33, y al mismo criar un par de hijos y un nieto, mientras la entropía del universo sube indefectiblemente hasta su tope 🎮 👾 🥁
Torrential rain in central London. Normally I feel a bit foolish sitting on the bus, but at the moment i'm rather pleased I left my bike in my office. #clausius #clapeyron
A Thought on Ambient #Temperature Changes
The total quantity of heat diffused and convected into the atmosphere should consist of the heat produced from the #radiations #emitted by the ground and absorbed by the atmosphere, the heat transferred by conduction and convection into the air from the heating of the ground by absorbed radiations from the Sun, the heat produced in the air from emissions reflected from the ionosphere.
Then there is #Thermodynamics with the myriad definitions, though a rational reflection on the work of #Carnot points to such consideration as the inter-convertibility of heat, Q, and the internal energy, E, of matter; and that pushes for #Particle #Physics understanding of the #transducer #physics of heat and internal energy of matter.
After all, such physics is applicable to the radiations conversions into internal energy of the ground constituents and on to conversions into heat and conversion into internal energy of the ambience constituents upon transfer into the air, etc. Then, of course, an interpretation of #HelmHoltz #Free #Energy relation in the context of Newton's Law is suggested as a #Heat #"Flow" equation/inequality with #entropy S as resistance consistent with #Clausius thinking on formulating against #Entropa the pure transformation.
#Climatechange, #Globalwarming, #NegativeEmission, #CarbobCapture
So there is the crux of the calculation of the heating of the Earth and of its atmosphere.
