Editing Butterfly effect (section)

==== Overview ====
The butterfly effect is most familiar in terms of weather; it can easily be demonstrated in standard weather prediction models, for example. The climate scientists James Annan and William Connolley explain that chaos is important in the development of weather prediction methods; models are sensitive to initial conditions. They add the caveat: "Of course the existence of an unknown butterfly flapping its wings has no direct bearing on weather forecasts, since it will take far too long for such a small perturbation to grow to a significant size, and we have many more immediate uncertainties to worry about. So the direct impact of this phenomenon on weather prediction is often somewhat wrong."<ref>{{cite web |title=Chaos and Climate |publisher=RealClimate |date=4 November 2005 |url=https://www.realclimate.org/index.php/archives/2005/11/chaos-and-climate/ |access-date=2014-06-08 |url-status=live |archive-url=https://web.archive.org/web/20140702105624/http://www.realclimate.org/index.php/archives/2005/11/chaos-and-climate/ |archive-date=2014-07-02}}</ref>
