It's necessary to fly to conferences to "get the word out"? COP 21 and many/most of the CC conferences are mainly and excuse to drink,party and feast. I guess these folks have never heard of video conferencing. Lead by example is always the best way, and the CC movement fails on that big time. If they can't give up "normal conveniences", why should anyone else feel the need? It's not the "fat oligarchs" that are the problem, it's the rest of us in our millions. Shouldn't be that hard to understand if your not fixated on an agenda.
