Well there is a lot of false information out there about climate change and it's probable influence on the planet. Things have gotten out of hand with how polarised this issue is. Many people on the right don't believe in climate change. A little of this is because the time scales were off in some early predictions such as An Inconvenient Truth. This was a good wake up call to many but it also exaggerates the rate of change to the point that many of the predictions should have already had massive negative impacts. This leads people to think they've been lied to. Screaming at them and telling them they're ignorant climate change deniers does little to encourage this. To think they don't care about the survival of the human race is not accurate. They just don't think it's at risk. IMHO the truth without the us verses them stuff is the key. I think 13 Misconceptions About Global Warming by Veritasium on YouTube is a perfect example of this. Yes it's easy to get mad at people when the fate of the world is on the line but that's not as productive as trying to understand them and reaching out to them.
This seems a bit like the Y2K problem. Even if we collectively get our sh*t together and manage to avert the worst effects of the crisis, there are always going to be people who will wonder what all the fuss was about.
And conspiracy theorists will have fodder for the next 50 years.
Barack Obama has only four years to save the world. That is the stark assessment of Nasa scientist and leading climate expert Jim Hansen who last week warned only urgent action by the new president could halt the devastating climate change that now threatens Earth. Crucially, that action will have to be taken within Obama's first administration, he added.
2. The Independent: "Snowfalls are now a thing of the past" (2000)
According to Dr David Viner, a senior research scientist at the climatic research unit (CRU) of the University of East Anglia,within a few years winter snowfall will become “a very rare and exciting event”.
“Children just aren’t going to know what snow is,” he said.
Regardless of the end times arriving for President Obama, he surely had as much meaningful data available as we do now regarding climate....and what did he do?
Eventually we will have a Democrat President...get ready for a deafening wave of silence when that President does as little or maybe even less than our current one. Rest assured if that President is elected during a recession, putting people to work will override climate concerns.
Republicans (and the equivalent rich conservatives in other countries) believe that climate change is happening anyway, and that anyone who doesn't try to make money off it is an idiot. They don't buy the survival of the human civilization bit - they think it'll affect only poor people, and that the rich will be safe. And honestly, they're right, at least for what we'll see in their lifetimes. Poor people are going to die in their millions in the coming decades, and rather than seeing themselves as the cause of this they see themselves as protecting themselves and their friends and families against it by insulating themselves with money.
if the survival of human civilisation isn't enough, what can you propose
Tell them the magic elves demand doing your bidding? Because both things are on the same level of rationality? Civilization, as such, is in no danger.

To OP: The problem will solve itself if the population of the world goes down enough, whether naturally or through some actual catastrophe. Indeed most of the world's birth rate is low enough that we are well on the way of a solution. Look up which parts of the world still have massive population growth and then see how many liberals you can get on board with trying to reduce that. Good luck.
