Time For Some Climate Honesty

Half-truths are doing no good

Let’s assume that you have doubts about ‘global warming’.

Some people do and, truthfully, we utterly lack the ability to accurately model how much warming will happen, where and by when (emphasis on accurately).

The reason is not for lack of trying or continual learning and model refinement, but centers on the complexity of the task.

Even seemingly simple systems that are actually complex are impossible to predictively model. An example is a pile of sand growing grain by grain that will finally slump at some unpredictable time and in an unpredictable way. You would think that such a simple system could be accurately modeled, but that’s not the case. Exactly when the pile will finally slump is unpredictable. Exactly how large the resulting slump will be is also unpredictable. The “when” and the “how much” are unknowable (using current modeling techniques).

All that can be calculated for certain is that a higher pile with steeper sides/areas (a.k.a. “fingers of instability”) is more likely to slump sooner and more catastrophically.

Now consider the tasks laid out before the global climate modelers where feedback loops abound, unknown variables still lurk, and the final result is the summation of multiple interacting complex systems. It’s not a pile of sand granules, it’s a gigantic interconnected system composed of heat flows, cloud formation, wind and oceanic patters and currents, variable solar and cosmic radiation, volcanoes and dust and jet trails and a thousand other inputs all interreacting with and influencing each other…in unpredictable ways.

It’s chaos theory (i.e. the butterfly effect) which means it’s way beyond anything we can currently model with any accuracy or confidence.
