Air Pollution Rules Buckle Under Brutal Heat Waves

Extreme heat waves are breaking out all across the country, and some environmental activists are questioning whether this unprecedented summer is making the EPA's air pollution regulations obsolete.

And she explains why the EPA's cap-and-trade system for managing these pollutants is having trouble keeping up.
