Simulate "The Day After Tomorrow" On Your PC 285

Posted by timothy from the well-not-on-mine dept.
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.

If it weren't for our timely sentience, many species we've killed over the years would still be around (mammoth, anyone?).

            Insects like the cockroach won't "take over" (any more than they already have; most species of land animal are beetles) because you can't get much bigger than a beetle without your exoskeleton collapsing under its own weight. Insects like the cockroach lived alongside the dinosaurs and didn't "take over" their ecological niches when they died the way the mammals did for this reason. "Bacteria" is an even sillier answer because bacteria have been around for even longer than insects.
          • Not necessarily. Roaches have little selection forces at play, same with humans. Perhaps we're both at an evolutionary dead end?

            I think the prime candidates for evolutionary leaps will be the species under great environmental or ecosystem pressure. They have the greatest opportunity for random beneficial traits to become dominant.

      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...

      The earth and life are robust, but we aren't. Most of human civilisation has occurred within a 10,000 year period since the last glaciation in which ice sheets covered much of the Northern hemisphere. The climate has been particularly and unusually stable for the past millenium. This is not going to last. If (as is very likely) the ice returns, or if global warming stirs up the climate, millions could die and many more will be forced to migrate. In terms of life as a whole on our planet, what we do matters little in the long term, but we could, and probably will, make things very unpleasant for ourselves.

    • What most people like to forget or not know is, the possible phenomenon of global warming will be a runaway (positive-feedback) process, just like the runaway global cooling that happened a few hundred million years ago. With increase of temperature, already now many white areas have disappeared. Not only at the poles but also on mountains like the Alps. This decrease of albedo will cause further warming, as more energy is absorbed, hence increasing the rate of warming.
      There is another positive feedback:
    • There are several indicators that Earth did not have a massive carbon dioxide atmosphere, as well as that oil and natural gas are from virgin carbon and not recycled.
      • There were not increasingly greater deposits of carbonate rocks created further back in time.
      • Carbon isotope ratios have not become altered due to recycling.

          Yeah, I read about that as well - and reading between the lines of the media take, they were forced to drop the issue by the government. Apparently the Prime Minister who don't like "so called" experts telling people what to think, don't really like it, when people take issues with his own handpicked experts.

          Since I have not read the (now withdrawn) findings by the Committee, I choose not to base my judgements on their findings.

          By the way - I wasn't even thinking of that Committee, but was thinking of a smallish 5 page (I think) dissection [math.ku.dk] (page 12 to 17 of that pdf) of a just a small part of his book - by Inge Henningsen, who is an associate professor at the Statistic Department [stat.ku.dk] of the Institute for Mathematical Sciences [math.ku.dk] at Copenhagen University [www.ku.dk].

          She also notes in her piece, that he's not actually a statistician like they know them at her department, as he has a M.A in Political Science [ps.au.dk] from Århus Universitet [www.au.dk] and teaches "Methods" there as well. He is (as is noted) "an associate professor of statistics in the Department of Politital Science".

    • That movie is expected to draw furhter focus on the environment and specifically global warming.

      And what we learn from the movie is that this global warming you speak of causes a 10,000 year winter. Or, the warmer it gets, the more snow falls on New York ... or something like that.

    • The Abrupt Climate Change FAQ [ucsusa.org] from the Union of Concerned Scientists, has a lot to say on the subject and the movie:

      Can what happens in The Day After Tomorrow happen in real life?

      No. The dramatic, virtually instantaneous and widespread cooling envisioned in the film is fiction. But like all good science fiction, the film is premised on several important scientific facts. We know with great certainty that the Earth is already warming, largely because as we burn fossil fuels and clear forests we are releasing carbon dioxide and other heat-trapping gases in the atmosphere. This warming is expected to continue in the coming decades, accompanied by changes in rainfall patterns and rising sea levels. The possibility of an abrupt shift in the climate system is only one feature of a changing climate that is expected to become more erratic, with extreme weather events like droughts, torrential rainfall, and extreme heat becoming more common. We can slow down global warming and reduce the likelihood of future abrupt climate changes by reducing our emissions of heat-trapping gases.

      The other interesting thing it mentions is that Abrupt Climage Change refers to changes that happen over years to decades as opposed to climate change that is happening now over decades and centuries. Make no mistake, we have changed our climate more in the last hundred years than in the previous thousand years.

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.
