Perhaps many of these "scientists" have no research of their own and merely cite papers for their own papers?
"Scientists say…" "Experts say…" I have a lab coat in the garage. If I put it on and go out and check the thermometer am I a "Climate Scientist?". If I go right after and take a person's temperature does that make me "Multi-Disciplinary Scientist" as well? If I wear the lab coat with temperature notes in the pocket and register as a democrat do I become an "expert?"
