I am not saying there is no crisis coming, but I recall reading that Tehran will be out of water in two weeks, two months ago. What's up with that?

Ever heard of clickbait?

It is unlikely Tehran will just evacuate all at once. They will do something drastic when the problem can no longer be ignored. And random events like rain will delay the inevitable for a while longer.

Perhaps this is how climate change will end up as well.

Sounds like it would be cheaper to build desalination plants on the coast, and pipe the water in. Iran certainly has the technology and brainpower to do that.

They share the same gas field with Qatar, who does all their desalination with all the excess gas production they can’t sell. Qatar has no surface freshwater or groundwater. So all of their water is desalinated. It’s often still quite salty to the taste though - the last few ppms would be an exorbitant cost to remove. However, Qatar has 3 million people. Iran has 92 million people - 9 million in Tehran alone. So thei…

In world first, Israel begins pumping desalinated water into depleted Sea of Galilee

Maybe it’s selection bias but: The saddest thing about Iran I’ve noticed is the stark contrast between the current state of the country and the intelligence of the people I’ve met from this country.

Greed is emotion-based. Intelligence isn't necessarily the best counter against emotion.

Hmm, I'd expect better from Yale to be honest, this reads like BBCesq style snow melts in winter click bait.

Tldr: City that outgrew its water supply recommends moving to a place with more water.

Although you wouldn't really get that from reading the article, which seems more about blaming people for Tehrans rapid growth and weather conditions.

Earlier quoted context omitted.

Clean water use for data center use has literally zero impact on water situation in Iran. Datacentres don't consume water.

Yes, they do. For example, only 60% of Equinix’s DCs use closed loop, non-evaporative cooling systems… https://www.cdotrends.com/story/4492/balancing-energy-and-wa...

Does cooling destroy H20 molecules somehow?

Though the problems of the world are increasingly complex, the solutions remain embarrassingly simple. - Bill Mollison

What simple solution are you referring to? Depopulating Tehran?

I like the idea of working with nature to solve problems. As a start, instead of, as you suggest, depopulating Tehran, they could populate it with trees. Chad is a perfect example of how to turn a deserted landscape into a "Great green wall of Africa" as they call it. And they did in only two years.

Am I missing something? How data centers in US/EU evaporating water thousand of miles from Iran affect it? Does it disturb the rain cycle in Iran or something?

Water is going to be needed to cool all these data centres going up around the world. They will gobble up electricity and water.

You realize the cooling system in a data center is a closed loop that circulates a fixed volume of water, right? Your kidneys are filtering 200 liters of blood per day. OMG, where's all that blood coming from?!

Yes and just like our bodies, that closed loop is cooled by a rack of evaporators on the roof.

I grew up in the Brazilian state of Minas Gerais, a region full of natural resources and, thankfully, aquifers and natural water reservoirs. However, centuries of extraction mismanagement and, more recently, over exploration of mineral resources puts these water resources into jeopardy. (Other problems include mining in open pits and with sludge dams that led to two of the worse environmental disasters in the world i…

You forgot to mention what may be the most serious water problem in Brazil. Agribusiness invests heavily in the Cerrado, the Brazilian savanna. In the Cerrado originate the vast majority of Brazilian rivers, which supply water to almost all of Brazil. Its trees, with deep roots, retain the scarce water of the region. This entire region has been deforested for the production of soybeans and cattle ranching. Brazil is a great exporter of water, which it currently does in the form of meat, soybeans, coffee, and paper.

Today we are experiencing unprecedented droughts in the region. In the future, we will pay a much higher price.
