Contemporary climatic analogs for 540 North American urban areas in the late 21st century

I guess sometimes you just have to throw the officially acknowledged lack of regional skill for GCM’s out the window~ctm From Nature Communications Abstract A major challenge in articulating human dimensions of climate change lies in translating global climate forecasts into impact assessments that are intuitive to the public. Climate-analog mapping involves matching the expected…

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…

Mechanical Models

Guest Post by Willis Eschenbach [NOTE the update at the end of the post.] I’ve continued my peregrinations following the spoor of the global climate model data cited in my last post. This was data from 19 global climate models. There are two parts to the data, the inputs and the outputs. The inputs to…
