When the fires first started, I remmeber being told that the days high should have been in the 80's but because of all the smoke the average temperature below the smoke went down to 69*F. That and it was windy, it really didn't feel like a heat wave.
First question: Is that what is meant as the outcome of a nuclear winter, that with enough smoke or filth in the sky, the air below (if breathable) is cold?
Second question: School me on global warming. I've always believe it to mean more extremes not just warmer. While I understand that certain compounds trap heat in the atmosphere, how is it that a smoke filled sky can do the opposite when they are a larger concentration of CO2 gases and stuff?
