"Incoming: The Chicxulub Impactor, Part 6 â Now What? By Stephanie Osborn"
"In the last 600 million years, at least 3 large asteroids have impacted
Earth, sufficient to generate craters of order 100km (60mi) across or
greater. These are Chicxulub (in Yucatan, Mexico), Popigai (in Siberia,
Russia), and Manicouagan (in Quebec, Canada)."
"It means that Chicxulub ISNâT unusual. It isnât a one-of-a-kind event.
Itâs a semi-regular occurrence on geological timescales. It means figure
out what to do NOW, while thereâs time, because it IS gonna happen
again. No âmight.â No âmaybe.â It WILL happen again."
This is what we need to be spending money on. Not this fake global
A: The interval between large impacts is much larger than the usual duration of species.
Odds are we'll be gone and the things that replaced the things that replaced the things
that replaced us will be long gone before the next major impact.
B: knowledge of potential impactors is much more complete than it was thirty years ago. Odds are
we'll see a mountain sized impactor long before it hits.
C: Except for K/T there don't seem to be many global extinction events definitely tied to
to impacts. Your flood basalts seem to be a lot more effective at streamlining ecosystems.
Note that there was an on-going flood basalt event when Chicxulub happened.
D: If there was an actual rock headed this way that required any sort of major effort to
divert, you'd be part of the Space Rocks Are Fake News crowd as soon as the tax implications
