You're on to something here! Very few humans will choose to make their own lives worse for uncertain benefit to humanity as a whole. Thus the climate effort eventually becomes an effort to make the lives of certain other humans worse. Fortunately only a few people have that power to any great degree. They either work out what you have above for themselves or have it explained to them. Sometimes the explanation comes from climate scientists horrified by the prospect of their work being used to make people miserable! The end result is what we see, that nothing ever seems to get done about climate change, other than normal technological advances that would have happened anyway.
