What are Al Gores credentials in the area of global warming?
Where did he study to get his doctorate?
What is his area of expertise?
If he wants to be taken seriously,then he should be willing to take the heat over his remarks.
There is a program at Boston University that answers your question. It is called University Professors and it allows people with a Ph.D. in one field to teach classes in a field in which they are interested, as long as they can demonstrate sufficient knowledge in the field and teach one course in the area in which they have a doctorate. Of course, they already have the research tools down pat. An example is an English folksinger who has a doctorate in psychology but who teaches folk lore. The man has made a career of history and music.
An educated person can do research in many fields.
Consider that most science journalists have undergraduate degrees in a particular scientific discipline and may have master's degrees in journalism. Their job is to communicate with the layperson on science.
Frankly, not many scientists are good writers: they tend to use the passive voice.
So, part of Gore's role is as university professor and part is as science journalist.
