Scientists expand their knowledge, learn more, change their opinions about certain facts. That’s just how it’s done.
If you encounter anything labeled “settled science” or if you ask a question and get shouted down as a “science denier” then you can be sure that the topic under discussion isn’t science at all — it’s just political science. Which is mostly lies based on nothing.
Don’t leave out “We have consensus.”.................
Well said. But if you said it on Twitter you’d be banned.
