I see a lot of people.talking about water consumption by data centers.
Big question is whether the water is consumed or just used.
Water is a renewable resource, so you can take it out if a river, run it through a heat exchanger, and return it and the water isnt consumed, it's just used and returned.
It seems that one major way of cooling is evaporative cooling. So the water is evaporated into the air, and eventually will fall as rain, and whether that's consumption becomes really complicated since it depends on local weather patterns and the like.
I do think there's an argument to be made that there's environmental effects from injecting Olympic swimming pools worth of water into the air every month. I would fully expect that to change the local climate.
Rest assured everyone that the parts stolen from a roadside sign that run my social media empire use not a drop of water for cooling!

@sj_zero Plus where is the water coming from: if rivers or groundwater, it could have effects downstream (either reduced flows or increased temperatures) or in other parts of the aquifer (reduced levels mean some wells run dry).
@sj_zero Water Consumption meme arguments are one of the reasons I became a climate change revisionist. Too many things are attributed to CO2 when a lot of it is likely ecological rebalancing. Removing water and things which contains it means you're removing that much passive natural cooling from an area, and that's ignoring things like shade and the layers of growth in a forest or shrubland.
Take a single square meter, 1x1, and imagine a centimeter of rain falling on it during a spring storm, a totally reasonable amount for most temperate areas. That's 10,000 mL or 10 Liters of water. Water has an incredibly high specific heat and heat of vaporization, which is why evaporative cooling works so well. The single square meter being covered with concrete would remove this. It's easy to see how this plays out in real life looking at urban heat Island effects and seeing how areas like Minneapolis have hotter temperatures than parts of Florida. Basically everyone freaks out about carbon, but the original conservationist movements to preserve woodlands, wetlands, and open areas were always the most correct.

@BowsacNoodle @sj_zero my fav is commie destruction that's magically 'climate change' ie the salton sea or the aral sea
Concrete jungles are awful compared to forest.
When we go camping it's very noticable in how much cooler it is on the lake verses a mile or two away.

@BowsacNoodle @sj_zero AND CONCRETE IS AT LEAST KINDA REFLECTIVE
CONSIDER THE WALMART PARKING LOT, PLASTERED IN BLACK TACKY ASPHALT
IF YOURE WALKING ALONG IT FEELS LIKE THE AIR TEMP JUMPS 30 DEGREES STEPPING OFF THE LAWN ONTO ASPHALT

@BowsacNoodle @sj_zero THATS BESIDES THE SHEER EYESORE FACTOR
@sj_zero THEY'RE NOT TALKING CONSUMPTION OUT OF BIOSPHERE AT LARGE, THEY'RE TALKING LOCAL MUNICIPAL WATER SUPPLY CAPACITY
BECAUSE THAT RAIN WILL VERY READILY FALL OUT ELSEWHERE
>SO JUST SCALE THE CAPACITY UP
THAT WOULD BE THE ACTUAL REASONABLE RESPONSE NOW WOULDN'T IT
BUT WE'VE KILLED THE HYDRO TECHS WHO ONCE MOVED RIVERS IN THE WEST

@dictatordave @BowsacNoodle @sj_zero THESE GUYS SAW THE SUCCESS OF AMERICAN HYDRO ENGINEERS AND GOT STARS IN THEIR EYES THINKING ANYTHING IS POSSIBLE

@BowsacNoodle @sj_zero DRIVING IS ROUGH AND IT CORRUGATES IN RESPONSE TO FORWARD ROLLING FORCE -- BUT ITS A ROAD TYPE THAT YOU CAN RESURFACE WITH YOUR CAR AND A PLOW -- YOU DON'T NEED THE MUNICIPALITY OR CONTRACTORS FOR IT
AND THAT MAKES IT WORTH THE DISCOMFORT
AND THAT MAKES IT WORTH THE DISCOMFORT
@sj_zero WE'VE BEEN RAGGING ON CALIFORNIA TO INCREASE THEIR WATER RETENTION CAPACITY FOR FIFTY YEARS NOW AND NOTHING
THEY REFUSE TO EVEN CATCH THE FUCKIN SNOWMELT
I HATE THIS SHIT SO MUCH
ITS LIKE THE PEOPLE IN CHARGE ARE GUESTS ON A VISIT AND DON'T HAVE TO WORRY ABOUT WHAT HAPPENS LONG TERM

@sj_zero "WELL THE DROUGHT CONTINUES PLEASE MODERATE YOUR WATER USE"
"WELL WE'VE PUT RESTRICTIONS ON RESIDENTIAL WATER USE BUT THAT DIDN'T HELP THE DROUGHT BECAUSE ALL THE WATER IS GOING TO FUCKIN PISTACHIO AND ALMOND TREES"
"WELL WE'VE HAD RECORD RAINFALL AND FLOODING BUT THAT DIDN'T HELP THE DROUGHT"
ITS A GOOD THING THEY'RE TOO INCOMPETENT TO BUILD A BIG PIPE AND SUCK UP THE GREAT LAKES FOR FRESHWATER LIKE THEY WANTED TO

@wildflower @sj_zero WELL LONG TERM THE CASCADIA SUBDUCTION ZONE CRUSHES DOWN AND THE ENTIRE WEST COAST GETS APOCALYPTIC FROM BAJA TO VANCOUVER ISLE FROM INFRASTRUCTURE FAILURE
BUT THAT'S JUST SOMETHING WE'LL HAVE TO DEAL WITH
BUT THAT'S JUST SOMETHING WE'LL HAVE TO DEAL WITH
@sj_zero dont worry guys its science we are not exposing the local water supply to demons trust us trust us trust us trust us trust us
@BowsacNoodle @sj_zero There is a big flood on the whites Brazilian state right now. The state is also a big food producer and has almost no wildlands left.
Meaning the influx to water bodies is much higher than the output...
Nobody talks about this. Only muh climate change!

@BowsacNoodle @sj_zero For a while in the past I'd have to drive a half hour out of and back into a city. I noticed that the city was always 2-4 degrees warmer than the country. No variables like lakes or time of day or any of that, just paved vs not paved, and may be that pollution also had a localized effect over the city.
@deprecated_ii @sj_zero HOW BIG ARE WE TALKING
THE WHOLE PURPOSE HERE IS EVAPORATIVE COOLING
YOU DONT WANNA BUILD A HOTHOUSE AROUND THE THING YOU WANNA COOK

@nugger @sj_zero very big
and skinny
with a hole in top
and condensing plates
and a basin to catch the water and reuse it
and maybe some turbines in there to get some bonus green energy
in the end it's a question of which compromises you want to make. mostly, the compromises are "the cheapest we can get away with on this land we bought because it was cheap" which is not exactly five star systems engineering

@Squadalah_Man @sj_zero This is very true. It's actually common for frost to start later in the cities than the country because of the heat island effects, sometimes 1-2 weeks. That can be the difference between growing plums or not, as they tend to flower close to first frost time north of The Mason Dixon.
