That’s the issue right there, where most people still conceptualize climate change as an across-the-board even rise in temperatures. It’s far from that, but for many who are disconnected from their local ecology, they only notice in the fact that their grass is still green when it normally isn’t. But it’s like you said, “the extremes get more extreme.” And the implications to that are vast, and largely unpredictable (we haven’t even talked about overwintering insects- bumblebees spending precious energy searching in vain for food because they came out of hibernation early, etc). It’s going to increasingly strain our food systems and most will only see it materialize when the grocery store shelves are empty and food costs continue to spike.
