New paper finds more evidence of the ‘poor performance’ of climate models — ‘Paper published in the Journal of Climate
Study 'finds there has been 'little to no improvement' in simulating clouds by state-of-the-art climate models. The authors note the 'poor performance of current global climate models in simulating realistic [clouds],' and that the models show 'quite large biases...as well as a remarkable degree of variation' with the differences between models remaining 'large.'
As Dr. Roy Spencer points out in his book, “The most obvious way for warming to be caused naturally is for small, natural fluctuations in the circulation patterns of the atmosphere and ocean to result in a 1% or 2% decrease in global cloud cover. Clouds are the Earth’s sunshade, and if cloud cover changes for any reason, you have global warming — or global cooling.” This new paper is one of many that demonstrate current climate models do not even approach the level of accuracy [within 1 – 2%] or ‘consensus’ required to properly model global cloud cover, and therefore cannot be used as ‘proof’ of anthropogenic global warming, nor relied upon for future projections.
