Once we find practical processes that take energy and generate large quantities of atmospheric gases, we will be able to admit there are huge potential benefits and costs to influencing the world's climate. Right now, though, the world's economy depends on burning stuff, which generates CO2, which appears to be radically influencing the climate in a costly way. The emotional easy thing to do is to just deny reality. Once these processes are practical, and I think they will be eventually, the incentive to indulge in fantasy will be gone, and we'll just adopt the processes to further human interests, and the brief (maybe 100 years?) period during which we knew about the problem but emotionally struggled to accept the reality of it will be just an odd blip in history.
