If the haze was caused by smog, why wouldn't we have it year-round?
This is not true, Erick is wrong. Summer haze is a combination of smog and high humidity, but it IS actually smog. Mainly, what you are seeing are VOCs (volatile organize compounds), aka pollution from power plants, cars, etc. You don't see them during the winter, not because there is no humidity, but because it takes a combination of high temperatures, sunlight, and little wind to cause smog to form (the compounds react with other molecules in these conditions). Those conditions lead to temperature inversions in the atmosphere, meaning the air is not circulating up and down in the atmosphere. Basically, warm air is trapped near the ground rather than rising and mixing in the atmosphere, and when you have those basic conditions previously mentioned, smog will form. This is why you don't see smog in the winter months.

I don't know why they are jumping on you either. You didn't disagree with them. It happens to me too on here. The other day I noticed people doing that to arjay. It's like they see a thread title and automatically assume everyone posting is at the other end of the political spectrum.

Sorry, I didn't actually read the whole thread because with topics like climate change, I don't really believe there is a debate. In my opinion (supported by lots of work, reading of peer-reviewed publications, etc.) climate change is happening, so there shouldn't be a debate about it. It's like debating if Cell Theory isn't real, because it's "just" a theory. Same with the Theory of Evolution - it shouldn't be debated, but it is. That's how I look at climate change. (EDIT: Before I get pegged for saying it shouldn't be debated, yes, science in general should be debated. That's how we learn - maybe debate was a bad word to use, but I think you get my drift.) So, that's why my comment didn't argue anything about climate change, but rather comments about smog - smog formation can easily be explained in a few sentences.

Anyway, sorry if it looked like I was pouncing on you, i just read LovinDecatur's post and didn't look back to yours, which she was referencing. Sorry about that!

Blahblahblah. Prove your assertion.

I can't tell if this is a joke. Your public profile says you have a PhD. Smog formation is pretty basic environmental chemistry - you can google that term and you'll get a million hits that say what I said. With your education level, I'd think you easily have the skills to do very advanced research (lit reviews, etc. - not lab research unless that is your field) - google search should be easy. I'm not trying to be snotty, but I really can't tell where you are coming from.

Your exact quote was "Much of that haze is natural." That is false. Most of the haze is human-produced smog. We're not fighting with you, we're just trying to point out your incorrect assumption.

LovinDecatur, maybe you didn't read my post about the scientific, peer-reviewed article that showed most of Atlanta's haze comes from humans? CCATL is right, it's very basic atmospheric chemistry, the kind of stuff you learn in intro classes. It's baffling that you think humidity is the main cause of Atlanta's haze, yet you have not provided one shred of evidence why you believe this.

Thanks for the report from the Environmental Protection Agency. I was actually running low on bathroom tissue,

I don't think "much" means most. You can have 1% of something gigantic, and it's still a whole lot. Yes, humidity can cause haze.
