Roughly 25 years ago, San Antonio had a snowstorm of 11 inches IIRC. Houston has had at least one ice storm before also, including at least a bit of one from a storm giving Austin 3 inches of snow in early 1985 (or maybe I am 1-off for year, and that occurred in early 1986 or late 1985.) - Don Klipstein (don(a)misty.com)

They'd get us up about 5:30 or 6 AM, and march us to the chow hall (which the A & M call the "mess hall") for breakfast, and we all froze our asses off! Cheers! Rich

I just got my new bill: 116 KWHr. It's 9c in my place, and the thermostat's set to 6c. How about yours? -- Cheers, James Arthur

The snipped conspiracy was: you thought I said something on Nov. 22, the archive didn't support you, so you imagined I somehow altered it, internet-wide, after the fact, on all the world's computers, archives, and servers. That's a conspiracy theory. <snip> > Congratulations.

I've established that I know models are simplified, yet I don't seem to realize models are simplified? That's dense. I write models for Pete's sake. > Despite your scepticism, one can make broad-brush predictions about > the climate without knowing the exact path that the ocean currents > follow from the equator to the poles.

On what basis can you say that you can make broad-brush predictions about climate by representing ocean currents--an absolutely massive heat transport--with a lumped approximation? Here's a lumped approximation: the mean global temperature of the Earth is about 14.5c. Therefore, there's no snow, no ice, and no glaciers. Since those aren't reflecting sunlight anymore, increase your heating assumptions dramatically...Oh dear, we're burning up! Does that work? Climate hangs on not just the global mean temperature, but how the heat's distributed geographically, and the thermodynamic processes that distribute it. You know, poles, ice caps, equator, tropics, winds, clouds, currents, etc. > Obviously, this loses you the bobbles on the on the warming curve that > correspond to the El Nino and La Nina alternation, and the similar - > if slower - alternation in the North Altlantic Multidecadal > Oscillation, but these are oscillations and cycle back to repeat > themselves over the years, while the CO2 level just keeps on going up. > > I'm not saying that a more detailed model capturing more of the > observations wouldn't be better, but computer based simulation always > depends on manipulating a simplified model of reality, and their > usefulness - in this context - doesn't lie in exactly predicting what > the climate will look like next year, but rather roughly what it would > look like in a century. You're thrashing the obvious. The question isn't of minor imperfections, approximations, or limitations of all models, but of gross deficiencies in the global climate models. > Effectively you are asking for a weather prediction program, when you > should know that such programs break down due to the butterfly effect > with a fortnight, and you are ignoring the techniques used to immunise > climate prediction programs agains the butterfly effect, as well as > neglecting the obvious point that the current generation of climate > models are aimed at finding out how difficult we are going to make > life for our children (or nieces and nephews) and their children and > are thus sub-optimal for predicting next years weather. What makes you think a) global climate models are immune to sensitive dependence on initial conditions, and b) initial conditions are sufficiently accurately known to predict future climate? Or that c) Accurate initial conditions aren't needed? -- Cheers, James Arthur |
