The problem is to a large part one of attack surface, if we don't have anything to talk about we talk about weather because weather effects everything and everyone. Thing is, all our systems are tuned to how the weather is right now, if climate and thus weather changes, problems can potentially pop up just about everywhere. Now we can talk about the systems we know are at a critical location, like coral reefs, but the actual problem is about unknown unknowns: Right now we are taking the bet that the worst problem connected to a changing climate that nobody has thought about is quite bearable, which to me doesn't look like a good bet.
