Does the Uptick in Global Surface Temperatures in 2014 Help the Growing Difference between Climate Models and Reality?

Guest Post by Bob Tisdale This post includes calendar year 2014 global surface temperature data from GISS and NCDC. I thought it would be interesting to begin the introduction as if GISS and NCDC were announcing year-end business profits at their press conference today. [sarc on.] INTRODUCTION Today, two of the world’s climate-industry giants—the NASA…

The Best Test of Downscaling

Guest Post by Willis Eschenbach In a recent issue of Science magazine there was a “Perspective” article entitled “Projecting regional change” (paywalled here)  This is the opening: Techniques to downscale global climate model (GCM) output and produce high-resolution climate change projections have emerged over the past two decades. GCM projections of future climate change, with…

Interesting Post at RealClimate about Modeled Absolute Global Surface Temperatures

We recently presented and discussed modeled and observed global surface temperatures in absolute terms. See the post On the Elusive Absolute Global Mean Surface Temperature – A Model-Data Comparison. The WattsUpWithThat cross post is here. Yesterday, Willis Eschenbach at WUWT furnished EXCEL spreadsheets that included the outputs of climate model simulations of global surface temperatures…

Hump Day Hilarity – model the bouncing ball

Josh writes: Talking of Climate Models, there is another great Climate Audit post titled “Unprecedented” Model Discrepancy where Richard Betts, once again, provides cartoon inspiration in the comments. It’s a bit like watching a ball bouncing down a rocky hillside. You can predict some aspects of it behaviour but not others. You can predict it will…
