When I do radio or television interviews, it’s very common for me to be asked about “my opinion” on global climate change. The article linked above captures the heart of my response. I.e., I really don’t know how to have a viewpoint on a subject that is at odds from the established scientific consensus. The reason I believe in quarks and supernovae isn’t that I’ve experienced them personally, but rather that people I trust assert their existence. I’m really not interested in what some guy at the supermarket thinks.
