No one is entitled to a better standard of living at the expense of someone else, when people can come to terms with that is when you will be able to solve all the environmental issues affecting the planet.
If people could agree on that we wouldn't have wars either. Fighting over resources (aka some having a better standard of living) runs through our history. So if that if what it takes then the issues might never be solved.
In this comment you have NAILED why a lot of conservatives I know deny climate change. If it was just the science and not the policy many wouldn't deny it. But the way the climate change argument has been constructed if you accept the science you HAVE TO accept the solutions which are often created based on this "all people have the same value" lie that is the undercurrent of progressive philosophy. Add in the fact that all the solutions require "world government collaboration" (which conservatives read as "One World Government") and you have the perfect mix of everything a modern American conservative rejects.
It is the same reason why conservatives don't mind bombing the middle east (if it stops terrorists) but don't want to really help or accept the refugee fallout from middle eastern war. The empathy gap for all those people is huge, and sadly isn't very political as many non-progressive liberals really only get upset for a week or two about it when pictures of dead or hurt kids from Syria end up in their Facebook feed. Americans of all stripes never hit that critical point of empathy needed to actually sacrifice in ways needed to "fix" Syria, it is too easy to ignore. Climate change is the same except it doesn't even have the advantage of dead kid pictures.
Global warming will lead to rising oceans that will mostly hurt poor people first, and those poor people aren't all American (or even mostly American). That is the real reason why conservatives have trouble accepting climate change and probably won't accept climate change. They don't want world equality, in fact they like that their children being born on the right side of an imaginary line gives them a better shot in life than a kid the same age in the third world. The American Dream has always been implied as only for Americans, and never concerned itself at who would actually huff the fumes from the production of that plastic white picket fence that fills in our perfect family picture.
We are a century away at best from some sort of world acknowledgement that every common life is worth the same (we will always have elites), but the overpopulated future messy world that comes with that realization will look more like how China is arranged than some Star Trekian utopia. Probably at that point people will look back at the freedom loving, SUV driving independent and wasteful American with the same scorn that we look at slaveholders today. But it is asking too much to expect that mindset in modern people, it just is.
Either technology fixes climate change almost by itself (like electric cars become the cheaper option to drive), or we are doomed.
