When the relative range was large and the effects of nonlinearity could not be neglected, the nonlinearity periodic relative rotating orbits could be found using the nonlinearity initial conditions.

So too has the Rare Animal Range, replete with deer and guanaco, a South American relative of the llama.

To illustrate the range of probabilities revealed by the 400 simulations, Prinn and the team produced a "roulette wheel" that reflects the latest relative odds of various levels of temperature rise.
