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.

I should mention, for anyone not familiar, that 280 parts-per-million (ppm) of CO2 is roughly the amount in the atmosphere before the Industrial Revolution. The current amount is roughly 395 ppm (as per NASA's OCO-2).
395 ppm = 0.0395%.

It's tempting to think that the warm-phase alignment of the Atlantic and Pacific ocean cycles (AMO & PDO) had something to do with it, but that sort of thinking is called "climate denial" these days. :-)

An infusion of stem cells could help restore proper drainage for fluid-clogged eyes at risk for glaucoma. That's the upshot of a study led by a Veterans Affairs and University of Iowa team.

Yes! PBS is back to regular programming next week. NOVA!
So tired of the conventions, and the BS, and the speeches with the phony, practiced voice inflections!

So, apparently, that means I have to turn my TV back on? Oy.

Scientists have been stumped as to why temperatures in Jupiter’s upper atmosphere are comparable to those found at Earth, yet Jupiter is more than five times the distance from the sun. New research suggests that Jupiter’s Great Red Spot may be the mysterious heat source. Details: http://go.nasa.gov/2aizPi6
