This is great science writing. And if this happened today, unlike an excess of plant food in the atmosphere, it probably really would wipe out humanity, or at least a great portion of it.
We could be looking a lot harder for these things, and learning how to deflect them, but Congress would rather build a big monster rocket.
It’s not consistent with the scientific method. I agree.
It was apparently much worse than we thought:
As Kennett noted in a recent article in The Current (a university press maintained by UCSB), the crater would have led to widespread destruction, characterized by biomass burning, megafaunal extinctions and global cooling. “It’s much more extreme than I ever thought when I started this work,” he said. “The more work that has been done, the more extreme it seems.”
The discovery was made possible by a Chilean group of scientists who were studying sediment layers at the well-know Quaternary paleontological and archaeological site, known as Pilauco Bajo. Years ago, these scientists recognized changes in the sediment record that were associated with the YDB impact event.These included a “black mat” layer that coincides with the disappearance of South American megafauna fossils and human artifacts dated to the Pleistocene (12,800 years ago), indicating a severe shift in the climate. This was a major find since the vast majority of evidence for the YDB Impact has been found in the northern hemisphere.
Imagine that happening today. And here we’re obsessing over two degrees Celsius.
Better get moving on that vital SLS, so we can protect ourselves. #NotReally
Ummmmm…no.
The media hysteria is also mistaken (as always) in imagining that NASA human spaceflight has (and has ever had) much to do with science.
“We don’t understand climate.”
He’s not wrong.
[Update late morning]
Is climate change like an asteroid, or diabetes? I’d say neither, but to the limited degree that it’s an understood problem, diabetes is a much better analogy.
Woah!
Carbon dioxide helps things grow? Who would've thought?!
Big if true! https://t.co/wajoPG1G67

Remember the sister kittens we adopted just before Christmas?
Well, we took them in for their third vaccination yesterday, and (SURPRISE), it turns out that Ember (the one on the right) is not a sister, but a brother. The other couple who adopted the other two of the litter discovered that they had one of each, which meant that we did as well, and upon inspection, yup, things are sprouting down there that were less obvious when they were six weeks old.
So we’ve been misgendering him for several weeks; hopefully it won’t give him a life-long complex.
We’ve decided not to rename him; it’s not clear that combustion byproducts of wood have a gender (though they probably do in German), but now we’ve got to get used to saying “him” instead of “her,” and “he” instead of “she.” Fortunately it’s not a long-held habit. We’re looking at him with new eyes now. It’s funny, because he’s the smallest (he was probably the runt), but he’s fearless, and loves to attack his big sister.
This seems a little overblown to me, certainly currently.
I agree that it’s a special place in terms of radio silence, and would be a great location for very large radiotelescopes. But I don’t know many people who would want to live there, and never see the home planet. And they could do comm via lasers — no need to pollute the local “air” waves with spurious RF communications.
The fires and rain may give us one in southern CA in a few weeks.
