For the nth time, they're not using these models to predict the future. They are modeling a physical thing. They can physically change the bumpers, airbag positions, etc., on the real thing and see what happens in the crash test. The models only help them put the jigsaw puzzle together and generate the blueprint for the factories.
The process of observing things has a lot of influence, too. Alzheimers. People have lost their minds with old age for millennia. It was called dementia, misdiagnosed. It wasn't until 1977 that doctors basically agreed what Alzheimers truly is and the number of diagnoses has skyrocketed. Not because there are more cases, but because we are better able to detect it. Hey, kinda looks like one of those global warming prediction graphs. Maybe alzheimers causes global warming.
Bullshit, I actually have a friend who does exactly this type of modeling for Ford, and yes, they look at his models and change very major things based on those models. One of the biggest examples is dealing with body design for aerodynamics. First they build a lot of models on the computer, moving vents and mirrors and bumps and such, to ascertain the most aerodynamic results, then more modeling some physical and some computer, then they build a shell and bring that to the wind tunnel (another model) to test and make more changes, then finally they build the end results.
What are you calling bullshit on? Modeling aerodynamics is trivial as well. And it doesn't have to be that accurate.
Denny is funny, doesn't believe humans can do anything that affects the environment, lives in a place that imports 80% of their water.
Doesn't matter, because they can't model the spastic lashes of Denny's buggy whip as he leans out the window shouting at the oncoming traffic. barfo
Man this is getting bazaar. I can't see the connection of CFD modeling and a global warming model. I do see the similarities of the global warming graph and the graph of the interglacial cycle. It looks to me like the only difference between this current cycle and the last one if that humans are in this cycle. But they sure as hell did not cause it to be right on schedule.
That sounds like they are modeling a behavior, but then testing that behavior out in a controlled setting to prove the accuracy of the model. After the actual physical test, they then tweak the models and engineering specs. I think you agreed with Denny Crane, and don't even know it.
Maybe that's a good place to start, then. CFD is in fact a big part of global climate modeling. barfo
Really. Well temperature does effect viscosity, and enough drag can affect temperature. Do you have those projections?
People have come out and attributed a lot of things to "climate change" when there is no evidence that it's something that has been trending upward over a long period of time, or related to CO2 levels. There's no question that humans are causing increased levels of CO2, and that CO2 affects climate. But what would happen if we stopped all co2 emissions tommorow? Does anyone really know? Climate scientists decades ago believed we were heading towards another ice age, based on the former trends. If the Co2 is preventing us from going to an ice age that would actually be a good thing.
I have absolutely no idea whether our emissions are the primary driver of global warming/climate change. However, I do know that there is no amount of reduction of those emissions to which the primary polluters will agree. We could agree to curb ours dramatically and our economy would collapse because neither China nor India would agree to reduce theirs. They would take what manufacturing jobs we have left and keep running their economies on carbon-based fuels.
It's worst than that. If the US stopped all emissions period, it would make very little differnce in the overall emissions. Besides that, the inter glacial cycle would continue on track if every nation ceased all emissions.
From MARIS' article: Fire season in West so far is below expectations Widespread drought across the West had forecasters expecting an above-average wildfire season this summer, which so far has not lived up to expectations. (Forecasters got it wrong, as usual).
We had a record cold spell in Oregon last winter. Doesn't that mean that warming doesn't exist? Go Blazers
