This is scary, yes, but ultimately grounded in verifiable facts and many scientists have come forward to express their concerns. It is most certainly nothing like the Q nonsense.
I would say the key difference about the left is that the supporters of these kinds of movements rarely get much support at the top. Even Bernie Sanders and AOC have stepped back from supporting certain movements after criticism (I'm thinking of Venezuela), while such contrition on the right is rare (until the Capitol sedition).
>Members of Congress who think that climate change will destroy the world within 10 years?
Who, precisely? And what did they say?
> 'The world is going to end in 12 years if we don't address climate change,' Ocasio-Cortez says
I really doubt AOC actually believed at any time that the world would end in 2030 (cf. Paris Agreement's 2030 Agenda).
It's not a stretch at all. It's an offhand comment being compared to a months-long disinformation campaign. Frankly, I was generous.
They're both making headline-grabbing claims, but one of these is at least based in fact.
