Do you really find it amazing? Perhaps If you toned down your arguments and weren't so dogmatic people would be more willing to engage in an open discussion with you. You don't want to know about the effects of climate change, I'm sure if I begin to explain you'll run straight to google to find me some "evidence" or a table of stats to refute it. Hence I would be wasting my breath.
Qualifications determine how facts are interpreted. They also give the ability to weed out real "facts". Everyone these days has a phd from Google though so everyone sitting behind a screen is pretty much an expert. The people ( like Tim Flannery) who devote their lives from teenagers to the research and study of the natural world, have numerous peer reviewed papers and books published, well they are just hacks.
