CO2- What if it Doubles?
If CO2 doubles, from 280 PPM to 560 PPM, that will only cause an increase in temperature of 0.6 degrees Celsius. That's it, 0.6 degrees C. That's about 1 degree F. And that is only if everything else stays the same, which we know doesn't happen. We are around 400 PPM now.

Soot and dirt on snow and ice cause melting even when the ambient temperature is below freezing. Look at pictures of glaciers and you can see they are covered with soot and dirt.
