"but do you realize both are models built using the same tools" I suppose it depends on your definition of "same". Climate is a lot easier problem than weather. To predict weather, your model needs to have an accurate model of the world, and the finer the grid the better. Air currents, water currents, mountains, everything needs to be reflected in the model. Despite all that, some of the models do a fairly good job. They've modeled entire months and the model and what really happened are fairly close. However, there are months that don't match. So there is still work to be done. Climate, though, is just interested in the heat balance. A lot fewer variables are needed. A problem that the proponents of "it is all a solar cycle" have is that the solar constant has been, well, constant. Other than the variation that follows the sunspot cycle and the position in earth's orbit, the net amount of solar radiation hasn't changed since the 1970's.

Eric, CJ's "nuance" can be better explained this way. How do we know that high taxes is bad for business, when businesses can't even predict their day-to-day revenues with any amount of reliability? Same thing with global warming. We don't need to know what the weather will be like next week to predict how CO2 is going to affect the climate decades from now. I got that straw man from a letter to the editor of OC Register. I think you know how to respond to that. Tenchusatsu
