Wildfire and Grace have got some good points.
"we need to stop wasting our time trying to influence these corpogovernment meetings"
All too true. When do we as humans realize that those who facilitate(d) the end of the world, knew long before the masses that they were doing so, and decided to go ahead. That that fact means that those same people are not the place to look for solutions.
"I hope it all comes down to a question of money so that it will be possible to pay the fossil fuel firms money to KEEP IT IN THE GROUND--enough money to maintain the fossil fuel extracting firms' incomes as a percentage of world GDP and get their consent to replace fossil fuel with renewable energy"
I would really, and I mean REALLY, want this to be a viable choice. It is like my kids asking me "If you had a trillion dollars, what would you do?". Ignoring the most reliant point in that I will never have a trillion dollars. There is simply no government, no army, no police force, no world judicial system, to implement such a solution no matter who decides what.
Both people ignore the fact that it is not the oil companies who are polluting but their customers, us. This is akin to punishing drug dealers and ignoring drug users. The drug war was a massive failure and so will be our search for a solution to this problem.
It is obvious that if you were to bet, you are vastly more likely to win a bet on global demise than a radical change in human mindset, world wide. No scientist claims that this coming crises will kill all humans, but just a whole lot of um. I will hope and work for saving the planet and the human race, but my money is on preparing for the world that my children will have to try to live in.
