"This "butterfly effect" is discussed seriously in chaos theory circles. "

Yup. Those butterflies still cause a lot of problems.

In chaos theory, the butterfly effect is the sensitive dependence on initial conditions in which a small change in one state of a deterministic nonlinear system can result in large differences in a later state. [2]

That explains why climate change science is so inaccurate, impossible to know all the way initial conditions.
