Is the greenhouse effect biological?
No, it is primarily physical. Biological events 300 to 100 million years ago pulled carbon from the atmosphere and locked it up at the bottom of vast swamps, which formed our modern coal and oil deposits. But the burning of that coal and oil is not considered a biological effect. The excess CO2 in our atmosphere is not of biological origin in that sense. Some excess methane gas, however, IS from direct biological sources.
