This got me to thinking of some things though . . . A typical sodium lamp runs at 480 degrees F. I don't know how many of these lamps there (I did
look though) but think of the heat from that stuff alone . . . Then consider the heat given off by automobiles, fireplaces, computers, even people.
Again, no figures there, but it adds up. Any thoughts?
The heat given off by our technology is a lot but nothing compared to the amount of heat the sun hits us with every second of every day.
Also the oceans and atmosphere are massive heat sinks. Even if we burned every carbon based molecule on the planet it wouldn't have much of a heat
effect. The real heat would be CO2 trapping more heat from the sun.
I have seen that pic before, there is another pic that was taken in the 70's that is incredibly different. The older pic is so dark it is
incredible. I am really into astronomy and have seen a great deal of literature on light pollution. Its sad when you see the effects of it.
