Unlike Dr. Robert Davies (Nov. 16), when it comes to climate change, I do feel like a child peering at the controls and instruments of a 747. Weather and climate are extremely complicated and chaotic systems. Planetary temperatures have always been in a state of flux.

Over the past 18,000 years, much of North America was covered with a sheet of ice that has now receded northward. What possible naive thought could ever lead us to the conclusion of planetary temperature stability?

My very uneducated guess would be that it will never be stable. It will always be in a state of flux. If, in fact, Dr. Davies has so much more insight, please tell me: I'm planning a barbecue this coming April 15. Will he kindly predict if the weather will be conducive to such an event?
