Will their Failure to Properly Simulate Multidecadal Variations In Surface Temperatures Be the Downfall of the IPCC?

OVERVIEW This post illustrates what many people envision after reading scientific papers about the predicted multidecadal persistence of the hiatus period—papers like Li et al. (2013) and Wyatt and Curry (2013). See my blog post Another Peer-Reviewed Paper Predicting the Cessation of Global Warming Will Last At Least Another Decade. NOTE: In addition to the…
