To "slow, chronic, and indirect", I would also add "spanning most of a human lifespan." For these kinds of things we often don't realize something is brand new as of our lifetime. Said in another way, if something changes in our life when we are 2, we will tend to think that thing was always that way, even though it is very recent.

An example, forest fires in the West (coast US). They have always been around. So, many say, nothing new here. Yet, we don't quite grok that they are 10x worse than 50 years ago [1]. Thus, if you look at it across multiple human lifetimes we can see there is a radical difference. Across one lifetime and it might not seem like it is so different.
