I’ve received a lot of mail on my recent column on the effects of carbon dioxide on global warming (How are planes affecting the environment?). The replies were both pro and con on global warming and the greenhouse gas thing.
I read most of the reports and find them very interesting. The problem is in the raw data of temperatures in a given area or areas. If one looks at the average temperature over an extended period of time — like for as long as they have been keeping records — the data looks very confusing.
