Rules:

Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
- Blogsites are treated in the same manner as social media sites. Medium, Blogger, Substack, etc. are not valid news links regardless of who is posting them. Yes, legitimate news sites use Blogging platforms, they also use Twitter, Facebook, and YouTube and we don't allow those links either.
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF OCTOBER 19 2025
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

AI boom has caused same CO2 emissions in 2025 as New York City, report claims (www.theguardian.com)

Study author says tech companies are reaping benefits of artificial intelligence age but society is left to pay cost

The AI boom has caused as much carbon dioxide to be released into the atmosphere in 2025 as emitted by the whole of New York City, it has been claimed.

The global environmental impact of the rapidly spreading technology has been estimated in research published on Wednesday, which also found that AI-related water use now exceeds the entirety of global bottled-water demand.

The figures have been compiled by the Dutch academic Alex de Vries-Gao, the founder of Digiconomist, a company that researches the unintended consequences of digital trends. He claimed they were the first attempt to measure the specific effect of artificial intelligence rather than datacentres in general as the use of chatbots such as OpenAI's ChatGPT and Google's Gemini soared in 2025.

I don't know about the carbon emissions, the water thing in the article is extremely misleading. It claims that AI is using up more water than the entire yearly consumption of bottled water. The water usage estimates include the water used to cool the power plants generating the power (running the data center).

The last study on this said that the actual usage of water in the data centers is 12% of the total water usage estimate. Data centers don't normally use that much water. It would be like Niagra Falls pouring water over every data center.

Simple reality check: If you look at the cooling system outside any given data center—if they're using as much water as d article suggests—they'd be emitting a massive cloud of water, 24/7. It would be so much, they'd need a cooling tower on par with a nuclear power station.

So what's with the statistic? If you look at any given power plant on Google Maps you'll see cooling ponds all around it. That's the water they're talking about. It's part of the build of the power plant. It's not using potable water that would be going into people's houses.

Having said that, 12% of the water usage is potable water—in the worst-case data center/power plant matchup scenario. Where you have an older data center that doesn't use modern closed loop cooling systems that don't lose as much water to evaporation. I don't know what the statistic is, but I can sure you it's a lot better than 12%. A wild guess would be 4-6%.

Background: I was a security consultant for many years and traveled all over the US going into many data centers (sometimes, by breaking in! Hah). Inside, they're loud AF (think: standing next to a jet engine) and outside they'll have some big ass cooling units that are also kinda loud but not as loud as some of these articles make them out to be.

That was about 7 years ago but I doubt much has changed since then. I guarantee that those data centers are still being used and have been renovated to support AI-style hardware. The power from the utility was just increased and more cooling units were added. I seriously doubt they did much more than that.

From what I've read about the new "giga scale" data centers, they're much more efficient (and quieter... Outside). Those are the ones we want. If we replaced all the old stuff with new stuff, the statistics in articles like this would drop by and order of magnitude (just a guess).
