Okay. I have two options this week. I'm just
trying to decide on which one, and I'm also trying
to... Well, I'm going to give you the sources.
I believe you've done that before, and let's
decide based on that, because I have no other
way how to broadly... It seems the fairest. ...get
you to pick. So we got burstcoms .com. I think
that's what that says. And the other one is fizz
.org. Hmm. Let's do phys .org. We always like
a good physics one. Yeah. So this is from phys
.org. And sorry, I assume P -H -Y -S, right?
No, this one's F -I -Z -Z. Oh, okay. Just kidding.
It's the one you said. Okay. You're like, wow,
I chose so wrong. This one is by Nature Publishing
Group, edited by Lisa Locke, reviewed by Robert
Egan. Major droughts linked to ancient Indus
Valley civilizations collapse. I don't know when
it's from. Successive major droughts, each lasting
longer than 85 years, were likely a key factor
in the eventual fall of the Indus Valley civilization,
according to a paper published in Communications
Earth and Environment. The findings may help
explain why this major ancient civilization,
a contemporary of ancient Egypt located around
the modern India -Pakistan border, slowly declined,
and highlights how environmental factors could
shape ancient societies. They The Indus Valley
civilization was one of the earliest urban cultures,
existing between 5 ,000 and 35 ,000 years ago
around the Indus River and its tributaries in
modern -day Pakistan and northwest India. At
its peak between 4 ,500 and 3 ,900 years ago,
its culture was characterized by advanced cities
and sophisticated water management systems. However,
the reason for the civilization's prolonged decline
after this peak are not yet fully understood.
Female Mishra and colleagues simulated climate
conditions across the IBC region between 5 ,000
and 3 ,000 years ago. They combined these results
with data from several indirect measures of past
climate conditions, including the geochemistry
of stalocytes and stalagmites in two Indian caves
and the water level records of five lakes in
northwest India. From this, the authors identified
a temperature increase over the period of approximately
0 .5 degrees Celsius and a decrease in average
annual rainfall across the region of between
10 % to 20%. They were also able to identify
four long -term droughts between 4 ,450 and 3
,400 years ago, each lasting more than 85 years
and affecting between 65 % and 91 % of the IVC
region, which means... Something. Indus Valley
Civilization. Indus Valley. Yeah. Yeah. The authors
suggest that these droughts influenced settlement
location choice in the IVC between 5 ,000 and
4 ,500 years ago. They reported that settlements
were concentrated in areas with more rainfall.
However, from 4 ,500 years ago onward, settlements
shifted closer to the Indus River, probably as
the drought started to affect water availability.
The final 113 -year -long drought that they identify
between 3531 and 3418 years ago coincides with
agricultural evidence of major de -urbanization
in the IVC. The authors conclude that the IVC
likely did not collapse suddenly as a result
of any one climate event, but instead declined
slowly with the prolonged droughts of major contributory
factors. End of article. Okay, so yeah, I think
we've always known that water is part of a burgeoning
civilization. So it's, I don't know, it's a prediction,
I think, of what's going to be happening in the
next little while, or at least can show us that
we're going to be facing these same problems,
that weather patterns can change. Yeah, yeah,
the interesting is... Despite what you economically
plan for. Yeah. Oh, absolutely. And I think the
interesting thing about it is, you know, 3 ,400
years ago, did they have microplastics in the
ocean? Yeah. I actually have quite the backlog
of microplastic articles. Yeah. We can get to
those when we get to those. Yeah, exactly. So
yeah, I just thought it was interesting about
how it just slowly progressed. For them, ours
seems to be, you know, expanding a little bit
more rapidly, but look at what we're doing to
the planet. Yeah, it's also kind of crazy for
like how long ago it was. It was a really prolonged
fall of their civilization. Yeah, I would say.
It was a few hundred years, which is kind of
surprising. Yeah, how would they mark that? I
was like, here's the start of it. The weird one
was, and it fell in 3418 BC. Which is like, huh,
that's a very specific year. Yeah, no, but that
seems as good. Yeah, I don't know. You guys got
48 hours and 18 minutes or something like that.
I don't know. They seem specific in their numbers,
so maybe I can be specific like that. Probably
shouldn't because we always put it on a schedule,
but I did nonetheless. Anyhow, bye. It sounds
made up. Bye.
