These current-events climate stories are the most important pieces of news on the site. If the moderators are deliberately nerfing them (ETA: or exploitable algorithmic policy is allowing them to be nerfed), I find that extremely terrifying. I hope it is not the case.
In your opinion. Many other HN users don't feel that way and get tired of seeing the same topic over and over again. If it's not intellectually interesting and seems overly political it's getting that flag button clicked.
EDIT: Before downvoting/flagging me consider that maybe I don't hold the views you dislike. I'm making commentary in the comment section and only pointing out that perhaps it's not dang killing submissions but actually other HN users that don't agree with you.
