” may be enough to trigger a sixth mass extinction, a new study suggests.”

Always that wiggle room.

Isn’t that what they want? Humans are bad. The world would be better off without us. I would think libs would embrace this.
How can you question this — The report suggests that it may happen. What more proof do deniers want or expect? /s
