A new study says that violent space weather that could cost $2 trillion in damage is more common than previously thought
In the years 774 and 993, the Earth was attacked from space.
Not by aliens, but by a natural eventâand it was very, very powerful.
Whatever it was, it subtly altered the chemistry of our planetâs atmosphere, creating trace amounts of radioactive elements like chlorine-36, beryllium-10, and carbon-14.
And those provide the clue to what the event was: Those isotopes are created when high-energy protons slam into our air. That means the source must have been from space.
These must have been huge waves of subatomic particles that slammed into us on those dates. Spikes in the abundances of those elements were found all over the world, including ice cores from the Arctic and Antarctic, Chinese corals, and more. Generating that many particles isnât easy, and only extremely violent events can do it.
Several possible sources have been considered. One candidate is that the Earth got caught in the beam from a gamma-ray burst, the mind-crushingly powerful demise of a very high mass star. I wrote about this being the possible cause of the 774 event in an earlier article. However, GRB impacts donât usually create 10Be due to the detailed physics of the blast, so that makes a GRB as the source shaky.
Plus, theyâre very rare events, so having two happen in as many centuries is extremely unlikely (I didnât know about the 993 event when I wrote that article, or else I wouldâve been a lot more likely to wonder about other sources).

Hmmmn.
Haven’t heard this one before. Color me skeptical, but not willing to be completely rejecting it.
Yet.
IOW, whatever events these were, they had mostly a positive effect on civilization.
A CME is the basis for my novel on the subject.
It can summed up as: “Shit happens.” I think that’s something most people can agree on.
I didn't see a link between these events and the Vikings.

SPECUALTION GONE WILD!!!!!!!!!!!!!!!!!
And, yes, the data shows that we did have an era of global warming from roughly 1978 to 1998, just as we had an era of global cooling from roughly 1941 to 1976.
Does anyone remember the chaos and damage caused by Y2K? yes, me neither, but it was great for IT hiring.
It seems that ever since Darwin postulated that evolution occurred etc by using “let’s assume” over 100 times to get to that theory, that scientific method has died. Now, everyone simply reduces the unknowns by using “let’s assume” simplifications.
Example- why do tyrannosaur fossils have sharp teeth? Because they ate flesh.... No facts in evidence, and science, like jurisprudence, must base facts on evidence, not appearance, anecdotals or similarity.
We are returning to the dark ages, alchemy and astrology are the new sciences.
that would throw cold water on carbon-14 dating prior to 700 eh?
This falls under the heading of a comet hitting us. It has happened. It will happen.
And the only difference is we will know what happened and why.
Knowing those things will not changed the degree of sh!t that will happen as a result.
In the years 774 and 993, the Earth was attacked from space... creating trace amounts of radioactive elements like chlorine-36, beryllium-10, and carbon-14... when high-energy protons slam[med] into our air... Spikes in the abundances of those elements were found all over the world, including ice cores from the Arctic and Antarctic, Chinese corals, and more... One candidate is that the Earth got caught in the beam from a gamma-ray burst, the mind-crushingly powerful demise of a very high mass star. I wrote about this being the possible cause of the 774 event in an earlier article. However, GRB impacts don't usually create 10Be due to the detailed physics of the blast, so that makes a GRB as the source shaky.Thanks blam and Robert A. Cook, PE. I'm sure we had some topics about some research done, hmm, in Japan I think, about the 8th century event.

Prof. Gunnar Heinsohn has done extensive research on the “black matt” layer that was the result of a destructive event that brought down many ancient empires and began the decline of Rome around 200-300 AD. Archaeologist chronically downplay the comet-neteor impact causality of several such events, Richard Firestone’s “Younger Dryas” event chief among them.

Obama has cost the world more than $2 trillion in his 7 years as President. So what’s another couple of trillion in damage going to look like?
