The problem is the potential collapse of some civilizations. I have seen some serious predictions that the Middle East and North Africa in particular are vulnerable to potentially becoming uninhabitable in say 100 years due to too much extreme heat (https://www.mpg.de/10481936/climate-change-middle-east-north-africa https://www.mpg.de/10481936/climate-change-middle-east-north...). Civilization overall will grind on regardless, but you've got to admit that just the Syria refugees alone threw a massive kink in European politics. A lot of the countries that are predicted to suffer the most from climate change already are fairly poor. So the question is how much could climate change contribute to political unrest? I agree that it does no good to talk about climate change in very strongly apocalyptic terms. That's part of the issue in the US -- the largely politicized hype tends to frame this issue in almost quasi religious terms. Either you believe in an Impending Apocalyptic Doom That Will Kill Us All, or you believe in A Vast Global Conspiracy Scam Designed To Enrich Crooked Elitist Climate Scientists. While I think there's plenty of evidence for concern, I do think the evidence points more towards a slow creeping collection of issues more than any sort of mass apocalypse. For instance, the state where I live (Florida) is fairly vulnerable to sea level rises. What this means is that any infrastructure with a 50 to 100 year horizon has to now account for the potential that sea level could be much higher in the future if you want to really be safe (see http://www.southeastfloridaclimatecompact.org/wp-content/uploads/2015/10/2015-Compact-Unified-Sea-Level-Rise-Projection.pdf http://www.southeastfloridaclimatecompact.org/wp-content/upl...). I don't expect Florida to be wiped out by climate change related sea rise but consider how much of Florida civilization is by the sea, I certainly expect some pain points. For poorer countries with much less resources, the pain points might be a lot harsher.
