The issue with climate change is exactly that: change. Doesn't matter if it get colder, dryer, wetter, warmer than it used too. It is a huge undertaking to change the built environment to handle conditions that were once seen as exceptional. Houses, streets and waterways are normally replaced/adjusted on the scale of multiple decades or even centuries. Significant climate change is affecting areas everywhere on a single decade timescale. So infrastructure is now outdated much more quickly, and needs to be replaced/upgraded at a higher pace. This if hugely expensive and will lead to more waste and more emissions. And that is just for the built world on which we have a lot of influence. The natural world doesn't always have the ability to adjust; lots of habits are suffering and species are going extinct.
