I'm convinced it's not a problem with the guidelines or source. I would assume it was killed because it was flagged by users. Maybe someone is brigading this topic?
I guess you can only wait and see if the mods reverse the decision.
Someone above claimed it was "off-topic". Any idea how to get it unflagged or bring it to mod attention?
This seems like a very important article. Just as a point of comparison, tree planting is great and all, but something like ~100 entities are responsibly for 71% of all emissions.
I asked the mods via email and the flags looked normal to them. It seems like it has been the one too many climate change post recently and that some people got annoyed and flagged it because of that. What a pity.
