Unraveling The Heat Wave: Separating Weather From Climate Change

I intended for this column to be a discussion about global carbon dioxide emissions. However, I received quite a bit of feedback on my previous column on the Phoenix heat wave, and I want to address that first.

The objections were aimed at my contention that one of the factors involved in the heat wave, is the steadily growing concentrations of carbon dioxide in the atmosphere. This topic always stirs strong emotions in people.
