This AI model simulates 1,000 years of the current climate in just one day

Gillian Dohrn, University of Washington

So-called "100-year weather events" now seem almost commonplace as floods, storms and fires continue to set new standards for largest, strongest and most destructive. But to categorize weather as a true 100-year event, there must be just a 1% chance of it occurring in any given year. The trouble is that researchers don't always know whether the weather aligns with the current climate or defies the odds.

Traditional weather forecasting models run on energy-hogging supercomputers that are typically housed at large research institutions. In the past five years, artificial intelligence has emerged as a powerful tool for cheaper, faster forecasting, but most AI-powered models can only accurately forecast 10 days into the future. Still, longer-range forecasts are critical for climate science and helping people prepare for seasons to come.

In a new study published in AGU Advances, University of Washington researchers used AI to simulate Earth's current climate and interannual variability for up to 1,000 years. The model runs on a single processor and takes just 12 hours to generate a forecast. On a state-of-the-art supercomputer, the same simulation would take approximately 90 days.

"We are developing a tool that examines the variability in our current climate to help answer this lingering question: Is a given event the kind of thing that happens naturally, or not?" said Dale Durran, a UW professor of atmospheric and climate science.

Wrt industries that consider “data as oil”.
My webuse is solely DU and this chatbot I sometimes rant at called cleverbot. Its owner Rollo Carpenter seems okay. He doesn’t come off as creepy and absent a MeToo, I assume that most random people like that are just random programmers. And that thing has been around for ever.

And I use DU because Skinner, Elad and EarlG are pretty straightforward. It’s not the generic as based model of the web I have a complaint with.

But Google totally creeped me out. And especially if companies like that want to wade into other areas of life.

I thought you mentioned being a scientist Erronis? Maybe I misremember.
The two resident DU scientists eppur se muova and NNadir would may get that the postdoc is already an unstable profession.

It’s not really anything respectable to pretend that complexes of professional science and medicine with Google/facebook/apple/alibaba/tata/jio/airtel/small creepy ai companies etc is almost like democritizing science a la sleuths and RetractionWatch or Wikipedia.

I never even bought into RetractionWatch or Wikipedia or sleuths. Too self righteous.

I sleuth my own work and rely on the system of trust and don’t have patience with anything else. There is already the ORI.

Aside from marijuana use I don’t have anything to hide and I make a web journal so that this implosion of ai and other worthless junk tech can be stopped without taking me hostage.

Fortunately none of the labs I worked in formally nor any of the people I knew in the NiH system were sleazy.

I don’t have patience with sleazy institutions that try to exploit me as has almost certainly happened. But I can’t really prove it. And proving that should not be another spectacle or tumor of a cottage industry.


I just avoid ai and data and use the web as I used to circa 2011.
And the influencer, ad bot and security theatre and politics and garbage entertainment shit invading real life was never gonna work. Actual people are not going to yield territory or sell part of their home to their creepy credit card company or their streaming service etc.

My own govt at both the state and centre level can expect complaints about corruption in the local technology sector, poor data hygiene, sexual and generic harassment (which should grant me anonymity locally) and I post about my medication use without it being a part of anything. I work alone.


I am currently working on a paper that is probably going to end up being a correction to my earlier work. I won’t know for sure till I feed data into my new analysis model and any which I have no issues with the ORI sans any industrial conflicts of interest.

And I am a struggling and failed scientist but I am very clear about where I stand on everything and I take a draconian view of influencer culture leeching into spaces where neither influencers nor industries exist.

I should update a post in the Cannabis forum on that note. And post in the sexual harassment program.
I bet someone tries to sell DU as a lifestyle app someday .

I buy medical MJ from a small company risking a crackdown. I do download the handbook of my country’s narcotics bureau routinely.

But this is a post for the cannabis forum.
