It looks much larger than the Chicxulub crater (~200km diameter 72 tera tonnes of TNT), this must be a exatonne explosion, I measured the crater diameter to about 3500km!
It would take decades or centuries before the sky would clear after such an explosion, most likely resulting in a mass extinction event.
Considering that we're in the midst of the Anthropocene mass extinction event already, I'd say it would be a certainty. The only question would be how bad it would get. Given how much larger that crater would be than Chicxulub, I'm guessing it would exceed the "Great Dying" (Permian-Triassic extinction event) to take the crown.
Edit: The Wilkes Land Crater in Antarctica, which may be associated with the Great Dying, was "only" a little over 2.5 times larger in diameter than Chicxulub and thus still way smaller than the crater depicted. That said, I guess a nuclear crater wouldn't be associated with a flood basalt "exit wound" at the antipode the way an impact crater might be, so maybe it wouldn't be comparable.
Trump solves global warming with nuclear weapons. Get his Nobel prize ready.
That's actually a brilliant idea. Once you eradicate most of the humanity, the rest will sort itself out.
I was gonna say. With a crater that large, we all lose.
I call that winning.
it would also shatter tectonic plates, create rifts and reverse the directions some plates were moving, the asteroid impact you mention resulted in the Indian subcontinent (I'm simplifying a lot of things right now)
Well, now you've piqued my curiosity. Got a link?
The Wikipedia article I'm reading right now says that the Indian plate split from Gondwana 100 MY ago (33 MY before the Chicxulub impact), so that's not the connection. Further down the page, it says that the plate movement might have sped up as it passed over the mantle plume from the impact that created the Deccan Traps (my interpretation, BTW; the science isn't actually as settled as I'm making it out to be), but it seems to me that that wouldn't change the "result" of the plate colliding with Asia and creating the Indian Subcontinent, only the timing of the collision.

Everything I said previously was what I could remember, give this a read yourself, it's not long and it is really interesting
So they're really trying to fix global warming!
Combination sea level rice abd lots of much smaller nuclear explosions.
