The core physics of global warming/climate change in one graph.
280 (blue) vs. 400 (red) ppm of CO2 in the atmosphere
This graph was generated using the University of Chicago's MODTRAN computer model (link below). It is a theoretical calculation based on the HITRAN absorption data for CO2. The smooth curved lines represent black body radiation at different Kelvin temperatures, approximating the long-wave infrared emission of the Earth's surface at those temperatures. The CO2 absorption of that radiation is the band that spans ~540 to ~800 wavenumber, and the dip is the combined absorption of CO2 and water vapor. The absorbed IR energy "bends" the CO2 molecule from its natural arrangement. It is then released as kinetic energy which heats the troposphere primarily. The warmer troposphere loses this thermal energy through convection to the upper atmosphere, and by emitting its own long-wave IR in all directions - to space and towards Earth as back radiation.
I thought this graph was interesting because it puts the problem in some perspective. Global warming derives from this. You can see the difference between the blue and red lines, for that absorption band, is slight. The program quantifies the overall difference as ~1.66 watts/square meter. Solar radiation at the top of the atmosphere is ~1,360 W/m^2, varying slightly according to natural cycles.
You can play around with several different parameters. The default parameters (used here) essentially represent max. conditions. For example, no clouds/rain and 299.7 Kelvin (~80F) ground temperature.

#SodiumLightSunday

200 low pressure sodium lamps make up an artificial Sun at London's Tate Modern gallery - a 6 month exhibit installed in 2003.

"The research - led by Jackson Laboratory professor and Howard Hughes medical investigator Simon W.M. John - investigates the effect of vitamin B-3 on mice that had been genetically modified to be prone to developing glaucoma. The findings were published in the journal Science."
"According to the authors, this suggests that treatments with vitamin B-3 - also known as niacin, or nicotinamide - improves the metabolism of aging retinal ganglion cells, keeping them healthy. The fact that they are healthier and more robust for a longer period of time makes them more resilient to the pressure-induced damage."

“This winter, along with the several years preceding it, are emblematic of California’s natural water supply,” said Scripps climate researcher Dan Cayan. “California’s hydroclimate is extremely volatile, lurching from dry to wet on an irregular basis."

Why the change of precipitation in California from drought to rain and snow? Mostly cooling of Pacific surface temperatures off west coast of US.

Alfred Hitchcock #SodiumLightSunday

Hitchcock's "The Birds" used a special effects technology called the sodium vapor process, or 'yellowscreen'.
"An actor is filmed performing in front of a white screen that is lighted with powerful sodium vapor lights. Such light glows in a specific narrow color spectrum that falls neatly into a chromatic notch between the various color sensitivity layers of the film so that the odd yellow color does not register on the red, green or blue layers. This allows the complete range of colors to be used not only in costumes, but also in makeup and props. A camera with a beam-splitter prism is used to expose two separate film elements. The main element is regular color negative film that is not very sensitive to sodium light, and the other a fine-grain black-and-white film that is extremely sensitive to the specific wavelength produced by the sodium vapor."

Screen captures of solar activity, solar magnetic field, and cosmic radiation hitting Earth's atmosphere. Shows the inverse connection between solar activity and cosmic radiation. It's believed cosmic rays have a "cloud seeding" effect, which would mean that lower solar activity would cause more cloudiness of the atmosphere.

Just saw this available on Netflix streaming today and am going to give it a try. The episode topics looked very good. We'll see.
Anyone else see this and have thoughts?
