What they really proved, at long last, is that gaseous systems are stable for small perturbations.
In layman's terms: the Butterfly Effect is bogus. It takes a very large perturbation to convert a stable portion of atmosphere into a storm, and the flutter of a butterfly's wings is not significant to tipping the balance.

Uhm, no. You do not understand what systems are modelled by the Boltzmann equation, what Lyapunov exponents are nor what "global in time solutions" actually are. Lets pretend that the Boltzmann equation is a good model, on it's own, for atmospheric dynamics. This paper proves global existence of various norms of the solution, so that says that there is no time T less than infinity at which those norms become unbounded. Solution trajectories that start arbitrarily close are allowed to diverge exponentially in time. That is, there can be exponential sensitivity to initial conditions (ie. butterfly effect) with no violation of these results. Someone above mentioned the example y' = y^2, y(0) = 1 which has solutions which become unbounded as t approaches 1 from below. These results rule out that behaviour but not behaviour like y' = y. Solutions here are bounded as t goes to infinity but are bounded for all bounded times. Please, go back to grad school for a few years before claiming to understand what you clearly don't.
"Scientists" scared of goofy analysis are priests, not scientists. Take their funding away and use their PhD parchment for toilet paper.
Nonsense. I have much better things to do, like reading and posting on slashdot, than respond or deal with every crack pot who has an axe to grind but has no real idea how to do it. Seriously, you want to analyze the data? Go collect it yourself.
Those who can, do; those who can't, write. Those who can't write work for the Bell Labs Record.
