One of the biggest issues facing climate science today is the divergence of reality (observations) from the model output. The draft image from IPCC AR5 (seen below) clearly illustrates this as does the analysis done by Dr. Roy Spencer. WUWT regular Tom Trevor wrote this short paragraph in comments, and it seemed prescient to me, so I thought it was worth elevating to Quote of the Week.
You know when I was a boy I would build models, I wasn’t very good at building models, but I built them anyway so I could play with them afterwards. I would pretend that the models were real ships or planes, but I always knew they weren’t even close to real ships or planes. For some reason these people can’t seem to tell the difference between a climate model and the real climate.
