Conclusion If we follow George Box's scientific advice, then a logical, unifying, next step for «stadium wave» models is to collaborate with computational / mechanistic global climate models to answer this simple question: By appropriate adjustment of parameters, can mechanistic climate models exhibit stadium waves?

Type 2 results, even from global models used in a prediction mode, still retain real world information in the atmosphere (such as from long wave jet stream patterns), as well as sea surface temperatures, deep soil moisture, and other climate variables that have long term persistence.

Hansen's study — based on statistics, not the more typical climate modeling — blames these three heat waves purely on global warming:

We are helping you to understand that there are other plausible explanations for global warming, and the assumption that it is due to CO2 is based only on opinionated papers hand - waved through the peer review process by friendly referees [while skeptical papers rarely see the light of day], and by computer model outputs, which are invariably unable to predict the future climate, or even today's climate with all available past data as the input.

The major carbon producers data can be applied to climate models to derive the carbon input's effect on climate change impacts including global average temperature, sea level rise, and extreme events such as heat waves.

My idea is to take a simple sinusoidal model of a beat wave composed of 9 and 20 year cycles (the two main frequencies in the instrumental record of global temperature) and subject them to disturbances with a random variable having a standard deviation comparable to the standard deviation of monthly changes in the rate of change in global temperature.

By using an idealized heating to force a comprehensive atmospheric model, the large negative anomalous latent heating associated with the observed deficit in central tropical Pacific rainfall is shown to be mainly responsible for the global quasi-stationary waves in the upper troposphere.
