Ocean acidification tipping point, climate change tipping point, rose of wars and fascism, microplastocs - these are just facts of things that are happening. I feel like doom scrolling would be an exaggeration of things that are happening or will happen, not just reading about reality.
Think of it as being a different way of saying “anxiety scrolling”, because “doom scrolling” is primarily referring to the experience of being driven by anxiety to compulsively consume a never-ending stream of bad news.
For example, I had to cut myself off from following what is going on in Los Angeles earlier today because I recognized the signs of going past the point of merely keeping tabs on it to stay informed and compulsively anxiously reloading the page to see if there were any new updates.
