Concern about climate change is about its effects on us. Most of our great cities are coastal. We thrive in a temperate climate. We are dependent on fisheries and a whole food chain of other Holocene organisms. Having all that change would be incredibly disruptive to us. We’d survive (as a species) all but the most extreme scenarios but our quality of life could take a huge dive and many people could die. Obviously life will just keep evolving. There have been times in the geological record when there has been little to no polar ice and times of “snowball Earth.” Life existed during all these times but both these extremes would be more hostile to humans than the current epoch.
