I've found out through the years that many of the people with that title have less experience in the actual subject matters than ducks have with fornication.
All this CC stuff and the emotional impact of it seems to lack the acceptance of "scientific" data that shows the normal cyclic history of climate itself. On our planet we've gone from hot to cold to hot to cold more than once (as detailed in deep Antarctic and Artic ice. Right now we're in a warning to hot cycle from what we call the Ice Age to whatever the next step is and yep human civilization and industrialization has contributed to the cycle being bumped or burped a bit.
We've got to ask ourselves, what caused the increase in global temperature from the Middle Ages to let's say the 1600's-1700's? Over industrialization? Not even, but temps did get warmer. But the increase was it global or localized? Is it hotter in Africa, Asia or the Sub-Continent now than 500-600-700 years ago?
Now looking into Earth's geologic/magnetic history and projecting forward, we can see that the shifts in the magnetic poles can alter Earth relative to the Sun, causing climate change by changing the degree of solar radiation that strikes the Earth. (Magnetic field shift effecting the magnetoshpere). Could this be happening now? The magnetic poles have moved about 600 miles in the last couple hundred yeas. Of course there are those who say "conspiracy", but who's to say right or wrong over something that can occur over hundreds of thousands or years and then change back?
I don't know!
