What science model defines "climate"? Is "climate change" the first derivative of the "climate" function? What is that "climate" function anyway?

Otherwise I have no idea what you're babbling about.
I got to know about this from tyler burns wilan, http://greenlivingideas.com/2015/09/10/tyler-burns-advises-why-environme... .

I hope you're not operating under the impression that the dictionary is a science reference.
