"I suspect the major underlying reason why many 'won't listen' regarding the issue of Climate Change is that it's become fairly obvious that we cannot change its course, that it is basically a natural temperature cycle that we have seriously revved up via a massive input of the toxic byproducts of Industrial Civilization, that it is now beyond amelioration and that likely the best we can do at this point is simply 'ride it out'.
I'm sure we'll survive as a species. We are like f'ing cockroaches in that regard. But the next x-number of generations are looking at a Grim Passage and the various Ways of Life we have now are going to get badly mangled and in many cases plain wiped out.
That is, to say the least, a Tough Sell and Denial is so much easier, especially when many personally think they don't have to worry a future will only get here after they're dead. [But life is full of little surprises, isn't it?]
On the Up Side, maybe this will finally re-wire us to deal with Long Term Existential Threats. We're essentially still "See Tiger/Run Now" in our basic instincts and all Scarlett O'Hara ["I'll think about it tomorrow."] when it comes to things like say asteroid strikes." ...comment on The Slacktiverse: Climate change and Christianity
