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.
.. if back at the time of the dinosaurs all this carbon was in the air.. then how can be releasing it be the end of "life as we know it".. The Dinosaurs did quite well :)
Personally, It's my opinion that the earth is a pretty robust system and our climate models will be rather wrong.

Foolish. Current advanced computer modelling isn't even capable of predicting the weather next week with any great accuracy.

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.
Does it come with media fearmongering "THE WORLD ENDS TOMORROW. DETAILS AT 8" addons? Seriously. Every single damn weather event is a showstopper. If my team blew everything out of proportion like the media did, I'd sack em. Also speaking of weather... They can't even get the 3 days forecast even close much less years out.

Interested in weather, love/hate to watch tornados and hurricanes.. trouble is the news makes it out like "The Perfect Storm" is about to happen

So if the computer is big enough, the garbage-in, garbage-out problem disappears?
We can't predict the weather for the next week, but doing it for the next 50 years might work if we only can get a computer big enough?

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.
"There is nothing wrong with the planet. The planet is fine . . . been
here 4 1/2 billion years. We've been here, what, a 100,000 years, maybe
200,000. And we've only been engaged in heavy industry a little over 200
years. 200 years versus 4 1/2 billion. And we have the conceit to think
that somehow we're a threat? The planet isn't going away. We are."

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

You refer to the lie that some of the eco-freaks like to believe in. That is that we're "saving the planet". As George Carlin put it, "That planet is fine, the people are fucked".
You're right that the earths eco-system is very robust. It's survived meteor collisions, massive climate changes, etc. Human society isn't particularly robust though. While you may be fine with the eco-system taking a few thousand years to adjust to a new climate, most people aren't. I think mass famine because of crop failure and flooding of the coasts is a Bad Thing (for us humans that is). That's the real reason people should be concerned about climate change, and not this altruistic bull that a small minority wants to shove down our throats.

when you don't know all the variables involved?

And of course Bjørn Lomborg is wrong and totally unbelieveable according to the overwhelming majority of scientists from a multiplicity of disciplines, ass you should know if you pay any kind of attention to valid scientific debate (as opposed to articles in the Torygraph).
A bit simplified, climate is average weather.
It's a bit like while it is impossible to predict which days will get rain in Bergen, Norway this november, it's pretty easy to predict the average temperature, the annual rainfall and how many days it'll rain.
Take a look at one small section of the IPCC Third Assessment Report (TAR). Note the uncertainties and many "improvements" since the previous report, the SAR upon which the Kyoto protocol is based. Browse the report further for more uncertainties and recent discoveries.
We simply don't know enough about climate yet. For example, water causes most of the planet's greenhouse effect. Increased temperatures will obviously put more water in the atmosphere. But how much will stay as water vapor, and how much will condense into clouds? And will greater cloud cover be as a thin horizontal layer (which might cool the planet if it reflects more sunlight, or might warm the planet as a blanket which traps heat), or will the increased water appear as vertical rain-producing clouds?
