Simulate "The Day After Tomorrow" On Your PC

kpearson writes "climateprediction.net, a distributed computing project to predict Earth's climate 50 years from now, has a new add-on project to study THC slowdown (how climate might change as CO2 changes in the event of a decrease in the strength of the thermohaline circulation). This kind of rapid, extreme climate change is shown in the movie The Day After Tomorrow, in which New York City is treated to a 10,000-year-long ski season. Anyone can download the project's client software and participate in the simulation. climateprediction.net was previously mentioned in the September 13, 2003 article Distributed Computing and Climate Change." Clients are available for various varieties of Microsoft Windows, but none are listed for other OSes.

    We all leave our computers on
    - running this software,
    - thereby using more electricity,
    - creating more greenhouse gases and the like,
    - increasing global warming...
    and therefore getting a very accurate answer much sooner.

  3. Concerning the movie "The Day after Tomorrow" by Peden · · Score: 5, Insightful

    That movie is expected to draw furhter focus on the environment and specifically global warming. This is both good and bad, as too much focus on the environment can draw focus from other points of interesets. Danish Scientist "Bjorn Lomborg" (one of Time Magazines top 100 important persons) has been warning politicians to not forget other points of importance, such as healthcare and clean water. I hope this does not distort the vision of politicians around the globe, lets not forget how er priotitize.

  4. Looks like it will be a bad film by QuasiRob · · Score: 5, Informative

    Just from watching the trailers it looks like it will be another contender for inclusion on various bad movie websites.

    True, but isn't that a different problem?

    I admit I'm a bit clueless here, but AFAIK climate modelling deals with overall changes at a high level e.g. "It's going to be colder in the north atlantic by about 2 degrees on average in a few decades" and the like.
    As opposed to weather prediction which says "It will rain in this spot on this day"

    Just because we can't predict the 'noise' in the short term doesn't mean we can't determine overall changes long term.

    Yes my friend, you're missing something. The "pollen" that your friendly hashman refers to is most likely polm. The finest morrocan hashes are polm. I am unsure as to the genesis of the word, but it could be related to palm, or else is an indigenous north african word.

    There are varieties of hash called pollen I believe, but they are "brand names" much like "northern lights" or "silver pearl" are to skunk herb.

    Your dealer is either using the name in this way, or has bastardised polm. It seems to be a commonish error. But, now you know...

    The reason why 100% female plants are preferred to males is that they are much stronger and more productive. The ladies give us concentrated trichomes containing high levels of THC/CBD, whereas the males contain little of the active ingredients and give us a headache and a weak buzz.

    So, spread the word brother.! No more pollen. Polm!

    Hmm...

    Earth may have a self-regulating system we do not yet (fully) understand. When you say its a robust system, you are right. Our climate models may well be worth squat, right again.

    Dinosaurs did quite well for quite a long time, until they could...

    However, the issue is not whether human interventions can fully derail earth's climate or only tackle the parameters a bit.
    The point is, that the changes in the weather we as a civilisation started will most certainly affect our way of life as we know it. Human is considered the most adaptable species, present in all kinds of environments. I cannot argue whether we are going to drive ourselves into extinction or not by what we did to the climate, but surely life (and survival) in either dry deserts, frozen glaciers or stormy swamps has little to do with the current trends in economy. There is a vast difference between a habitable and comfortable climate, you see...

  10. Not gonna work by bigHairyDog · · Score: 5, Insightful

    I did a climate modeling project for my dissertation at university. These guys have a good idea - throw massive computing power at it - but it's not that simple. Compared to SETI or protein folding, climate modeling is not as highly parallelisable. Plus what's holding back the state of the art right now is the quality of the algorithms we're using - they loose accuracy pretty fast as the result of feedback between multiple iterations of a process that introduces quantisation noise each time.

    IMHO this project will produce the same quantisation noise-ruined results we have now, just more finely ovesampled

    Still, they might get some useful insights into how to tackle the problems of parallel dynamic system simulation

      We're not running a parallelised model across lots of computers, we're farming out a run to each of several thousand machines. And the purpose of the experiment is precisely to look into the feedback processes that govern how climate changes. You say: "what's holding back the state of the art right now is the quality of the algorithms we're using" and this - on climate timescales - is what we're looking to explore. Basically, the models that we have these days (IPCC TAR, for instance) lack any sort of quantitative measure of uncertainty. We're looking to find "error bars" for these sorts of predictions. See http://www.climateprediction.net/science/strategy_ adv.php for details of the experimental strategy. [We (& friends overseas) have submitted bids in recent EU Framework 6 and NSF rounds, to try to do something similar with very different models. This will help us conduct a convergence/verification process.] We have recently submitted a "first results" paper and are awaiting the reviewers' comments. So far, things seem to be going pretty well (though we'd love some more participants!). Cheers, Dave Frame climateprediction.net coordinator
