I think the reason everyone just has a "worry" or an opinion and there's so much disagreement is because nobody knows, even in the slightest what effect climate change will have on people's quality of life. We have predictions of some effects like temperature extremes, sea level rise, storm severity (or so I've heard, I can only find hand-waving in IPCC reports), mass migration, etc. but no credible and terrible predictions of numbers of deaths, financial cost or other more direct impacts on people. Maybe the climate will be radically different but we'll adapt just fine? Who knows? Nobody! So people invent their own beliefs and we end up with doomsdayers imagining the worse possible outcome and neverminders imagining the best possible outcome and they all want to control each other's behavior according to their own imagination. Now it becomes political and people hate each other because they see them working against each other's believed fantasy.

Even in this video, I couldn't find any quantified predictions of actual effects on people, so it just continues to support everyone's own fantasy, whichever way that goes.
