Just a reminder to the Climate Change Deniers. For well over a decade overall arctic ice has been decreasing at rates **faster** than older models originally predicted.

@freemo In Mathematics the modeling of something with as many variables as melting ice is never as straightforward as one would think.

@AmpBenzScientist Very true. Thankfully models are completely irrelevant to us knowing that Climate Change is human caused and already very much devastating.

@freemo The simple fact that the models have yet to accurately predict the severity of problem implies that not enough is known. This is similar to Euler's Method when an Improved Euler's Method is required with as many steps as possible.

@AmpBenzScientist That makes no sense. Models arent used to determine the curreent severity of a problem, theya re used to predict the severity we may expect in the future.

Models have no relevance on understanding that the effects of climate change have **already** been devestating, so no they dont and by their nature cant fail at that task, as that is not their purpose.

This seems to be a position drawn from complete ignorance as to what role models play in science.

@freemo A Mathematical Modeling of an event should be able to predict the magnitude of the event at any given time interval. This would include the past, present and future.
The Modeling that I do is much different and I was recruited for the purpose.
