>>90
When they have an atmospheric model that can take 1990's climate data and predict current temperatures--not even weather, just temperatures--let us know. They promise to be able to predict decades into the future. Let them start with 1990 and predict 2010. That's just twenty years, and that shouldn't be too hard, right?
Flawed logic. Later into the future = more carbon = more change.
For example, I don't know where I'd begin modeling average global temperature down to one tenth of a degree Celsius, because I don't know where I'd begin measuring average global temperature down to one tenth of a degree Celsius.
I think you may have a little misconception as to what mathematical modeling means. You can build a useful model without precise measurements. We know the laws of physics. We know how radiation heat transfer works. We use it every day to design engines and turbines. You can guess an average temperature to start with and then run your simulation with different starting temperatures. If there is always a significant increase no matter the starting temperature, then the model tells you that adding carbon increases temperature.
And for the record, I didn't say it was easy, just
easier than predicting a storm. As for how to calculate average temperature, I'm not a climatologist but this is how I would do it and I assume this is how they do it too because it's the only way that makes sense. Take temperature and multiply it by the mass of how much atmosphere is at that temperature. If there are sections for which you're missing data, interpolate (include this in your uncertainty calculations). Do this until the entire atmosphere is accounted for. Add all of these up. Now divide by the total mass of the atmosphere.
Like I said before though, we don't have a way to completely validate our models because we don't have an extra earth. That doesn't mean we should ignore what the models tell us. And burning less carbon is not the same as living in caves. Grow the fuck up.
When you look at the history of these people...
And... you've just demonstrated that you can't look at this objectively. Stay comfortable in your little world where everyone is out to get whitey. That way you have an excuse if you fail just like those whiny minorities!
