isn't global warming by definition universal?
The average global temperature is derived from a multitude of temperature measurements taken all over the world. Global warming or global cooling (which many were worried about not very that ago) is just the term used to indicate the current direction of change of that average temperature. Alone, it can neither describe local effects nor predict them.
Climatology is a fascinating subject, but I don't want to subject the members of this list to the topics of mathematical models and statistical analysis. Let's just get back to talking about the weather and how it affects the iris!
