Title: Would you tell the world if you knew an asteroid was coming to Earth?
Post by: EvaH on 04/03/2021 16:41:50
David asks:

If you became aware that a significant-sized asteroid was likely to collide with the Earth in the not-too-distant future (say months rather than years) would you tell your colleagues or tell government officials or tell the world? Or would you just sell the family home and have a great holiday (assuming post Covid-19 conditions)?

What would you do?

You donít need a nuclear bunker to protect against neutron bomb. Most are short range because neutrons are absorbed and scattered by air. Even a concrete wall or floor will reduce exposure significantly, so a basement/cellar will offer protection unless you are up close and personal, in which case the blast will probably get you!

I would think that any prediction of an impact would also have to include a time of day and direction, from which one should be able to determine a likely hemisphere of the impact.

Although, that would depend on whether it is coming in on a tangent to Earth's orbit where there may be some variance in the calculation, or at a greater angle up to perpendicular where an hour could mean the difference between hitting and missing.

If one knows where it is going to hit, there could be significant preparations possible from moving refugees to ensuring a food supply for survivors (which may be somewhat contradictory goals).

And, of course, attempts to either move it, or shatter it. A shattered asteroid might have a larger debris field, but each fragment would likely be eroded more by atmospheric entry, and one would get may smaller impacts rather than one large impact.

Nonetheless, I'd vote for informing governments, and the people.

Clifford's post#18 sums up the situation succinctly and admirably.  In answering the question - should governments tell the population about an incoming big asteroid strike.

Such a strike would have very different consequences for the total global population - depending on which side of the globe the asteroid struck.

If the asteroid struck the "Eastern" side - by which I mean, the side which consists almost entirely of the Pacific Ocean - the consequences wouldn't be too bad.  From a global perspective.

A 1km-wide asteroid plummeting into the deep waters of the Pacific would certainly create a huge oceanic convulsion

Which would spread out across the Eastern hemisphere, in the form of 300+ metre high tsunamis washing up against Australia and the south coasts of mainland Asia. And possibly South America.

However, the tsunamis would have little effect on the Western Hemisphere.  Which contains the main centres of civilisation - ie Europe and North America.. In these places, the population would not be greatly inconvenienced.

So I think European and North American politicians wouldn't mind telling their people about an asteroid which was going to hit the Pacific.

But if it was going to hit the North Atlantic, or even worse - come down on the land-mass of North America or Europe,
That would be quite a different story.  Then, wouldn't the politicians try to hide the truth from their people, about what was going to happen?

That very much depends on the size of the asteroid. If it was as big as the one at Chicxulub, it wouldn't matter where it hit.

The water hits are the worst actually, vaporizing untold volumes of water, plummeting the entire hemisphere (anything on the same side of the equator as the hit) into a biblical-scale flood and famine. Immediate effects like Tsunamis pale in comparison to the climate impacts.

If one is predicting an ocean impact, then one would go into Tsunami protocols.  A lot would depend on the size of the asteroid, but low lying areas would need to be evacuated, as well as potentially a number of islands.

Ships often like to ride out a Tsunami in a deep sea, but given a few days or weeks advance notice, they could also ride it out on the opposite side of the globe.

How long would water vapor remain suspended? Huge rain storms, but potentially short lived.  I suppose it would depend a bit on how much got up into the stratosphere.

The vaporised water from a mid-Pacific asteroid impact would descend as mere rain in Europe and North America.

We in the West could easily cope with that.   We wouldn't experience any "Biblical scale flood and famine effects".

Such effects would confined to the East.  And could be mitigated by our sending "Relief Aid" to the unfortunate eastern people..  Thus easing our consciences, and enabling us in the West  to carry on as normal.

A sufficiently large asteroid would scour the ocean floor, throwing countless tons of pulverized rock into the atmosphere and triggering a "nuclear Winter" type scenario.

I heard some estimates that the dinosaur-killer asteroid would have left a hole in Earth's atmosphere, and vaporzed silicates from the impact would have been blasted out into space.
- It would have cooled and condensed into billions of tiny meteorites, which would have rained down around the Earth for the next few hours
- This would have heated the surface of the Earth to pizza-oven temperatures for several hours.
- The remains of this deadly rain exists in the geological record in the form of tiny glass spherules, mainly in North America and Pacific

The nuclear winter would have followed, freezing any animals that weren't already baked...

The "Nuclear Winter" scenario has never been empirically tested.  I doubt that it represents the truth.  It was invented  during the SALT negotiations of the 1970/80's.  To scare people.

Personally, I think that we should not be similarly scared by the prospect of an asteroid impacting the Earth.

The chances are 70/30 that  the asteroid will come down in the sea.   The sea-water will provide an effective shield against the "pulverised rock" that you refer to.  Most of this rock will be never get out of the sea.  So won't be a problem.

If the asteroid hit the land, it would cause some more serious difficulties.  But I'm sure they can be overcome.

We are not mindless dinosaurs, but intelligent human beings!   We're not going to be wiped out by some stupid rock thrown at us.

Please adopt a more positive attitude!

The "Nuclear Winter" scenario has never been empirically tested.

For obvious reasons... but the prospect of nuclear winter is far more than just speculation. Models of it have been created, and they lend credence to the idea that nuclear war could indeed cause global temperatures to drop enough to cause us significant problems: http://climate.envsci.rutgers.edu/nuclear/

I doubt that it represents the truth.

Based on what?

It was invented  during the SALT negotiations of the 1970/80's.  To scare people.

Citation needed.

Vaporized water can't stop vaporized rock from getting into the atmosphere.

That entirely depends upon how big the asteroid is. A Theia-type impact would kill not only all humans, but all living organisms (including extremophilic microbes kilometers underground). A K-Pg-type impact could still kill many millions, or even billions of people. Even if that didn't make us extinct, it would still potentially represent the largest disaster known to have affected humanity.

Even supervolcano eruptions (like that at Lake Toba tens of thousands of years ago) can cause significant climate change. The K-Pg impact was many orders of magnitude more powerful than that.

Please adopt a more positive attitude!

I'd prefer to adopt a realistic attitude.

Yes, it did. That's another reason we know that charles is wrong about downplaying the danger of a water impact.

There is actually empirical evidence for it, and even in recent history.

1816 is known as "The Year Without A Summer" (https://en.wikipedia.org/wiki/Year_Without_a_Summer).  It is believed to be the result of a massive volcanic eruption of Mount Tambora, causing global cooling the following year.

I'm seeing some estimates of around 100,000 deaths, but today that number could be far greater, perhaps in the millions.  Hopefully not reaching the billions.

We are not mindless dinosaurs,
Dinosaurs were far from mindless. They survived in all sorts of environments for about 170,000,000 years and learned to swim, burrow and fly. The big guys even had two brains, making them four times as intelligent as a politician.

The odd thing about their extinction was its completeness. Land animals (including humans) clearly cannot survive major climate change because their environments are not robust and food may disappear quicker than the animals can migrate. But sea creatures can migrate continuously and the ocean environment and ecology are robust and change very slowly. Sharks survived, so we must assume that their prey fish also were not much affected by the dinosaur extinction event. So why did the ocean dinosaurs also die out?

Yes, the complete extinction of sea-dinosaurs is puzzling.  They might've been expected to survive, and then gradually evolve into dolphins and whales  That would seem a natural evolutionary process.

However, this process doesn't seem to be accepted by modern science, which claims that dolphins and whales didn't evolve in the sea.

Rather, they evolved from creatures which started out in the sea, then went onto the land, became mammals, then went back into the sea.

Is this fully convincing?

Thanks Kryptid.  I just felt vaguely suspicious about the proposed sequence:

1. Sea-living dinosaurs adapt to life on land;
2. Evolve into land-living mammals;
3. Then evolve back into sea-living equivalents of dinosaurs.

This seemed unduly complicated.  From an Occam viewpoint.  However the paleontological evidence in your post is decisive.

One of the surprising suggestions from modeling the Yucutan asteroid impact is that there was a very short, intense period where sub-orbital debris rained down over the entire Earth, raising the air temperature to pizza-oven temperatures for a few hours. That would have killed any animal that breathed it.
- Fish and sharks can both stay underwater permanently. Many species survived.
- Some species of turtles and crocodiles also survived - but they have a low metabolism, and can stay underwater for long periods
- Small mammals & dinosaurs in burrows could breathe the air in the burrow for a while
- However, marine dinosaurs were air-breathing, and needed to surface regularly to breathe

Undoubtedly, the subsequent "nuclear winter" and acid rain also contributed to global extinctions; but an initial sharp, short extinction event explains a few things.

Seeds and tubers can survive in the ground.
