"The haze that enveloped the Twin Cities on Friday came not from auto
pollution or evaporation, but mostly from Western wildfires whose smoke
has drifted over portions of Minnesota, prompting state officials to
issue an air pollution alert for the Twin Cities area."
Cars have nothing to do with the haze in Minneapolis ...right? ...Read

"...meteorologists are also watching a different pollutant, ozone, which
forms in the atmosphere in hot, sunny weather. And depending on the
weather, automobile emissions and other factors, ozone could reach a
level today or Sunday that would prompt another air pollution alert.
Elevated levels of ozone are also of concern to those with
respiratory disease, such as asthma. Even healthy adults and children
are advised to limit outdoor activity if ozone levels rise much higher.
"We don't want people to panic or think they can't go outside," said
MPCA information officeer, Rebecca Helgeson. "But we also think they
need to know that if they have certain health conditions, they should
cut down on the amount of outdoor exercise and just keep alert to what
their own bodies are telling them."
Confusing, isn't it?
