Not climate change. But three days ago this is a bit strange. Article regarding to anti-vax and astroturfing. First submission flagged https://news.ycombinator.com/item?id=27946430 Lots of comments saying it is being artificially vote inflated. Second submission more objections https://news.ycombinator.com/item?id=27951293 stating conspiracy voting. Not sure what to make of it. And just one example.
Thank you for the links, but I was asking about the (since-edited-out) claims that these comments were being downvote-bombed. Submission ranking is considerably more complicated, and is not what I was asking about.
