Don’t bite too hard on this one, Angry Poodle. There is no scientific theory as [global warming’s] basis, it is a set of results from a computer simulation. Note atmospheric CO2 went up from 1930-1970 with global temperatures dropping each year. Any theory has to account for that. You saw a drawing with the glass over the greenhouse reflecting infrared radiation back inside. The drawing is wrong. Glass does not reflect infrared radiation. Neither does a diffuse fog of CO2.
Seventeen percent of the earth’s topsoil has eroded since 1945. This is a real threat.
