It seems that in any climate change thread, many if not most of the comments get downvoted, much more to an extent than other topics.
Could someone scan the 50+ comment climate change posts and compare the controversial comment ratio (e.g. number of greyed-out vs non-greyed-out comments) and compare it to other types of 50+ comment posts? If the ratio is much higher for climate change posts, it seems like there's something nefarious going on (brigading, astroturfing, etc.).
