The links are often fine, but the sub in my experience is not. The head moderator also moderates /r/climateskeptics and there is a significant overlap between the two subreddits' userbases. This wouldn't be a problem necessarily but many of these users argue in bad faith and derail the discourse on the sub.
This seems like a common climate denial tactic. I’m seeing it in my home country as well. Lots of truly bad-faith skeptic contributions to climate change forums on Facebook, made by people who obviously don’t care about science or evidence.
