Climate change will not end human civilization, unless by "human civilization" you mean the very specific configuration that habitation patterns, agriculture, national boundaries and numbers of living humans all have at this very moment.
Likely hundreds of millions to a few billion will die that need not have died, wars will be fought, relocation and migration will be of unprecedented scope and scale, there will be hunger and disease ... but "human civilization" will persist through all of that. Thats not a reason to celebrate, it's just a reason to describe the risks and outcomes accurately.
