In global warming and climate studies, figures are often given in Watts per meter squared (Wm^-2) -- what does that mean? Surface warming ratios are variously cited as 0.1 °C per Wm^-2 forcing through 1.0 °C per Wm^-2 -- and most everything in between -- which ones make sense? Are climate models programmed with reasonable assumptions on cause and effect? How is the world actually responding? Have claims of "the smoking gun for global warming" been validated? We'll try to sort it all out for you.
