There's a compelling reason scientists think we've never found aliens, and it suggests humans are already going extinct
Unchecked climate change would eventually lead to widespread devastation on Earth. Rising seas would inundate coastal cities like Miami, searing heat would increase human mortality, and acidic oceans would become inhospitable to fish and coral, leaving behind little but rubbery masses of jellyfish.

Yep,I've read about the Great Filter." and i do feel we are going to get snagged in it and I suspect many others on other worlds have as well.
The problem with the Great Filter is that once we figure out what it is it will be too late to avoid it.
Having said that, I'd like to think that there are other more likely scenarios that will destroy humankind before climate change does. For example, when crucial natural resources start becoming scarce, the resulting wars can destroy us before we have a chance to drown/burn/starve to death.
However, the gap in the Fermi paradox is large enough that even if the vast majority of intelligent civilizations are not really that intelligent and end up destroying their planet before they can escape (like us), you'd expect to see something. Yet there's nothing there. It sort of makes me wonder if the simulation argument is the right answer.
